You guys gota Help Me

Ive Wired up my car and everything fires Up (The AMP lights turn on)

Ive got a JBL GTO5355e 5 channel 660W AMP
Ive got a Mutant Sub connected to its dedicated SUB channel
And My Front and Left/Right Speakers wired up to the other 2 channels

The problem is, The Sub is working but the front speakers ONLY Play the bass too!
So what the sub plays the speakers are playing aswell. So I cant hear any vocals etc. Any idea why this is happening?

I havn't played with any of the AMP settings. But Is this normal?
I though everything would handle itself
SUB for bass
Speakers for the rest

But no :n:
Help Please

Check the LPF and HPF filters on the amp.

You have probably filtered out all the high freqencies from the speakers. It will be either a switch or a knob you turn. Have a play about with the gains set low.:y:

Rogue_Shadow

14th March 2009, 23:13

I did play around with mostly all the dials on the AMP. But Yea I thought it was somthing to do with the frequencies.
But I Definately couldn't see one that said Gain
I was So PI**ed off, Ive spent 7 hours running ALL the cables, only to find One speaker wont work and the one that did was gonna blow itself outa the doorcard

Stickyjam

14th March 2009, 23:25

sounds like you got LPF on?

Rogue_Shadow

14th March 2009, 23:27

LPF = Low Pass Filter?

Im guessing thats a switch (Prays)
Ive given up for tonight but please, throw your suggestions this way Because im gonna get up early to sort it all out

So I'll check to see if there is a LPF switch and turn it OFF

Thank You

keep it coming :clapping:

Grrr if Only it wasn't dark
Also Side notes to others looking to wire up there cars
AVOID THIS KIT! (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=350105021779)

Nothing wrong with the buyer, but the "Beats 700W wiring kit" is a very cheap and nasty kit. The 4 AWG seems ok, but the 16 AWG speaker wire...No, its crap, the copper can be pratically pulled out.
Cheap n nasty Fuse n holder also!

Avoid peeplings

Cant wait to get my AMP, Sub and Speakers playing Perfectly!
But im sure because of this kit im gonna have to rewire the speakers!

Maybe you have the RCAs [assuming you have two sets from the headunit] plugged in the wrong way round into the amp. So you would have the low frequency bass RCA from the headunit going into the front speaker RCAs on the AMP resulting in only bass playing from them, and the full frequency front speaker RCAs plugged into the sub RCAs on the amp.

Rogue_Shadow

15th March 2009, 15:06

Ive got a single RCA cable (2 plugs) connected into the back of my headunit, that then feeds the Front input on my AMP
I may have to take it to a Techy to sort it out, cause Im not getting anywhere
I managed to get Vocals playing earlyier but it was SO quite and it was still carring alot of the bass (Loads of vibration)
Ive disconnected ther sub and focasing on getting the front speakers carring the right noise.
Could my speakers be crap? They are FLI 5 intergrators 60RSM 160MAX

Well im curently up country for training, but im aiming to drive down to a audio shop and see if they can get it working. Its stupid! why the hell are the speakers copying the sub. I would of thought they would sort themselves out once i wired it. Grr!

Nah its not as simple as that! The amp still needs to be sending the speakers the correct frequencies ...

Sounds very much like HPF.LPF jobbie.... just need someone that knows what theyre looking at

liam_b

17th March 2009, 01:22

as said sounds like lpf filter is on but it could be because you only have 1 rca input to the amp how meny rca inputs are on the amp have you try pluging the rca leads into the different inputs

Rogue_Shadow

17th March 2009, 10:16

The headunit only has 1 preout, which goes to the input labled front on my Amp. I think it requires someone who knows what they are looking at. Defo gonna need to take it some. Huge thanks for your help though!

Stickyjam

17th March 2009, 10:49

if its a multi channel amp you have to send a signal to the other channels of the amp too...

get a rca splitter...

17th March 2009, 13:03

very much sounds like rcas wrong way around or hpf/lpf (check headunit too)

also sure your headunit has 2 pre outs 1 for sub 1 for front

just post a pic up am sure its dead easy thing to fix

AlexGreen

17th March 2009, 15:23

If you only have 1 pre out on your headunit you will need to split the signal when it gets to the amp.

Get a splitter and split the signal into the front channels and the sub channels.

Front channels set to hpf, sub channels set to lpf. Dont have the hpf on your headunit either if you have that option.

My parents took my car down to a Audio Techy who had a afternoon to look over it
He diaganoised pretty much what you guys did.
The headunit is top of the range however its not best suited for AMP's. he explained everything to detail to me, but overal he gave me my options
1) By a Mono AMP to run off the sub of the New AMP and run the 2 FLI speakers and 2 Saxo Stock speakers of the headunit

2) Scrap the Headunit and buy a new one with 3 preouts and run 3 preout cables to the AMP

The headunit is more than enough to power the speakers + I can always upgrade the stock saxo speakers at the rear. However it means selling my new AMP which ive had for 4 days on ebay.

Arghh what to do

Rogue_Shadow

17th March 2009, 18:13

Ive think I know what Im gonna do
Im gonna run the Sub through the AMP and run the speakers through the Headunit

Yes its a waste of the 5 channel AMP (only using one channel) However
Im aiming to buy another car within the next year or so and I dont want to Buy ANOTHER AMP to power a SUB if Im gonna be waiting to power up my next car (so i'll hold onto the amp)
The headunit does everything I want it it to, its major flaw however is it only has 1 set of preouts which is messing with the signal before it gets to the amp.
However Id be spending ALOT if I wanted a headunit that could run the Amp and have all the features this one does.

+ There is the buying and selling of the gear

Better off making as much us as I can with what I have and plan the build for my Next car

17th March 2009, 18:35

A top of the range head-unit which isnt suited to Amp's?? That doesnt sound right to me mate... Most top of the range head-units should be more thasn capable to run a sub and amp.. Anwyays,Post up a pic so we can see exactly what you've done and im sure it can be sorted from there.

Or.. As you said, run the sub off the amp stand-alone, and run the car speakers straight off the HU.

Best way IMO

imydaking

17th March 2009, 18:38

doesnt the amp have a 'high' inputs am sure it does

basically you take the normal car speaker wire and put that into the amp and thus giving it the full signal and not just bass for the front speakers...

also try rca splitter if the headunit pre out is full range

Stickyjam

17th March 2009, 18:57

sounds like you actually have a shit headunit...

so may aswell buy a real one so you can put that in this car and take it to your next, save the current to leave in the car for the next owner :D

just use rca spliters or buy a new headunit you dont need to spend mega bucks to get a decent headunit with 2 or more preouts

tbh i would try using rca spliters and see how thay go

same though this "audio tech" seems to of decided his sub pre out is only sending low notes?

dunno much about it tbh i always thought they were just labelled for ease of use...

rca splitters are cheap and potential useful later.. i linked to some earlier if you want to try...

liam_b

17th March 2009, 19:51

only sending low notes :S ive pluged the sub preout to my amp and got all signals

i dont see why a headunit with 1 pre out would only have a sub pre-out that only sends lpf

but it that in the case and it is only send lpf i would keep the amp and just get a headunit with 2 preouts

either way you need to buy a rca spliter unless you get a 3 pre-out headunit so id buy some try them if still nothing get a 2 pre out headunit

Rogue_Shadow

17th March 2009, 23:27

How does the RCA splitter work? I wish I could draw on this forum ha ha, would make it easyier. I'll detail at the bottom of the post how its all wired up.
My headunit only has 1 preout, which ive connected via RCA (red/white)to the input labled FRONT on my AMP.
My headunit by all means is note state of the art, but its not a Shite on Im sure
Have a Look ---->>> Headunit (http://www.caraudiodirect.co.uk/pioneer-dehp3100ub-p-7225.html?cadid=mhc0busgehivf9u9bdffn5jtq1)

(How its wired)
4 AWG from Battery to AMP
Remote Cable from Headunit to AMP
RCA (RED/WHITE) from Headunit to Amp (front input)
2x Speaker wire running from speakers to AMP channel 1 + 2
Sub Wired to dedicated Sub channel

Ohh, this is my Amp BTW (http://www.jbl.com/car/products/product_detail.aspx?prod=GTO5355&Language=ENG&Country=US&Region=USA&cat=AMP&ser=GTS)

Like I said, when I do get home, I'll most likely wire the speakers to the headunit and the Sub to AMP...At least Ive got some ICE then. Untill I figuer out whats the next step

liam_b

17th March 2009, 23:43

ummm have you tryed putting the rca leads into any of the other rca inputs on the amp? if not try that and make sure you have the hpf switched on

that headunit should be fine sending signal to all speakers

have you got the manual for the amp btw?

Rogue_Shadow

17th March 2009, 23:55

Yea Ive been through the manual and located all the dials for LPF etc, Ive had music (By music I mean PURE bass) playing through the speakers at low volumes and ive fiddled with EVERYTHING. But it didn't work
Yea I may try the other RCA inputs
Its strange why its doing this, Aw well, Hopfully I'll have somthing to show for all this eventually

liam_b

17th March 2009, 23:57

im looking at the manual at the moment you should have

1: the rca,s in the fr,fl rca inputs on the amp(there the left rca inputs on the amp)
2: 3 switches across from the fr rca input is the lpf, flat and hpf switch this to hpf
3: wire the front speakers to the fr and fl speakers outputs on the amp
4:tune the headunit on make sure it on low volume and see if you getting sound if no try the swtich that says EXT/INT Switch see if that does any think

if still you have nothink try turning the Front Input-Level Control knob that is next to the fr rca input if still nothing try the knob next to that

hope that helps mate its hard trying to fix things when you cant do it in person lol

edit: only just seen the post above try what i just put and if still nothing il have a think lol

Rogue_Shadow

18th March 2009, 00:00

How would a RCA splitter work? I connected the RCA cable from the Headunit into the Splitter then into the AMP?
Arghhhh
Just want to have somthing to show for all the time ive wasted on it lol

18th March 2009, 00:02

Thank You very much for your help

liam_b

18th March 2009, 00:04

im not sure if the rca spliters are going to help as it should be working without them

can you borrow a headunit off a mate to test as im thinking it might be a setting on the headunit as the headunit says its has 1 pre-out that is rear speakers or sub

Rogue_Shadow

18th March 2009, 00:10

Well my folk took ti down to this Audio techy who does these amazing boot builds, Ive walked past alot and see them. He said that I needed 2 preouts and to Run the RCA cables to the AMP..But whats the point of plugging in two rca's if Im only going to be using the front speakers? Aghh All this shit is confusing me now

I think im just gonna rip the Speaker wire I put in OUT (Because its poor anyway) wire up my speakers to the stock wiring and run the Sub of the AMP in the boot.
It will be a waste of an AMP but I'll have somthing to work with.

It seems my only way outa this is to get ANOTHER headunit, But If I do that I'll loose all the great features of the one Ive got now like ipod control, USB and Aux, No way Will I get one for a similar price. The its the hassel of selling what ive got now.

Major Suckage ICE!
Gonna have to think things over

Ha, i live in cornwall, thanks ha ha
its cool, ive got it sorted what im gonna do
run the sub off the amp and the speakers of the headunit. While i look for another headunit and get the cash together. So i need a headunit with 2 preouts! how was i to know lol. Ugh what a mess
what makes it worse is im miles away from my car till Friday. So all i wanna do is fiddle around but i cant ha ha

technically you dont need a headunit with 2 preouts you just need some splitters

---------============ RED

----------=========== WHITE

bam signal split from one rca into the same as 2...

Rogue_Shadow

19th March 2009, 15:04

So what do i need to attemp the rca splitter? ive got a rca at the headunit connected to the amp. So i need the splitter at the amp end...and im guessing another rca cable? id love to fix this with just a rca splitter, but i doubt it would be that simples

Stickyjam

19th March 2009, 15:11

http://www.caraudiodirect.co.uk/audio-rcay-interconnect-p-7025.html

id linked it earlier...

your current rca cable goes into that and the signals split then match white to white same as if it was 2 cables... etc

19th March 2009, 15:19

Mate, you need to set your pre-out to REAR not SW on your HU. read your manual.:y:

sounds like a possible problem.. but you will also need the splitters if you are to have both sub and speakers working off this amp and headunit combination

So that RCA splitter
I use it where the RCA cable meets the amp, and I plug one of the RCA plugs into the Splitter, then plug the splitter RCA's into the AMP?

pretty much white split into the white rca's on the amp
and the now split red into the red rca's on the amp..

obviously relating to the channels youll be using if theres 3 rca's on a 5chan?

Rogue_Shadow

19th March 2009, 18:32

Ok, But I had my RCA cable plugged into the input labled Front on the AMP

So Are you saying that plugging the split RCA's into the Rear Inputs, Everything will even out?

Rogue_Shadow

19th March 2009, 18:34

This may help

My RCA's currently connect to the Far Left RCA's (FL and FR)

Once youve split them send one set to the front channel and one set to the sub channel......left and middle on your piccy.

Set your pre-out on your HU to REAR, then set your filters on the amp.

liam_b

19th March 2009, 18:55

make sure you get the right rca spliter you want one with 1 female that splits into 2 males

try this
Use the MULTI-CONTROL to select SW SETTING 1 Press MULTI-CONTROL to display the setting mode and change it to off see if the output in now full range

Rogue_Shadow

19th March 2009, 19:31

I think when I tried it last, nothing external (stock speakers worked) when I turned the SW off in the settings. However reading over the manual online, seems there is an option I didn't access before
Under the SW settings there is an option some where to toggle between Subwoofer preout and rear speaker preout
I need to select the rear speaker preout option im guessing to get the right frequencis to the front speakers!
I ordered the FLI RCA splitter (http://www.caraudiodirect.co.uk/audio-rcay-interconnect-p-7025.html)
Ohh and they Sub input says Sub 1 and Sub 2? Surely I dont plug them into that?
