Amp wiring help please - Saxperience

Morgiee · 25th February 2010, 14:09

hi i'm used to wiring amp but this set up im doing for a mate has baffled me. The sub box works and the door speakers that im wiring to the amp work too but for some reason its eith one or the other that work but we want both the sub and the door speakers to work of the amp their is no sound. Iv'e got pics of it below but from what i make out its a 650W Kenwood amp and is a 4 channel setup, which is ideal for wiring a sub on 1 channel and setting it to pure bass and wiring the door speakers to another channel and setting it the pure trebble, but this doesnt seem to be the same. The model of the kenwood amp is:

Kenwood KAC-646X

and in the attatchment is a pdf version of the user manual:

And finally the pics of the terminals on the amp:

We also bought two of these splitters so that both phono inputs would rum of the same cable as the back of the headunit only had one set of phono outs:

One to split the red into to and one to split the black into two

Cheers

Those pics aint great. You have two pics of the speaker wiring. Which is components, which is sub?
Cant tell which the components are as their is only one set of cables?
From what i can see your bottom rail (B) is your stereo side so this would simply be your components.
Then on your top rail (A) then this would be your sub, with the settings as they are. Only thing i can think of is that the mono connections have caught you out?
See the pic below and the onces i have circled should work for your mono sub

Cheers mate appreciate this.

To try clear things up a tad:

-All hardware works fine alone
-The channels are both working
-The wiring is all hooked up correctly at the speaker end

I think we just havnt got it set up in the right order/combination.

Ive edited it pal, made a mistake.

Yeh sorry mate the orange cable on the bridge section that goes to the sub and the pic with the white cables goes to the door speakers, initially all we want is to wire the sub to one channel so that we can set it to full bass and no trebble and wire the door speakers to another so that we can set them to pure trebble. Can this be done with this amp? also for the phono cables their is only one set i appreshiate youll need another set so what we did is bought a splitter for the red and black cable a 1 to 2 phono cable so that it can act like their is two cable but of one line. Also tonto_vtr stated a good point that if their was only one phono ouput at the back of the HU then that might be only for subwoofer hense why we get bass in both the doors and the sub.

Is their a way around this?

Cheers hope that cleared things up the user manual for the amp is in the attatchment to help you mate

Well if their is only one sub out on the back of your HU then your likely to be getting an output for sub frequencies.
Still thought setting up your filters should help a little bit but no miracles.
Your sub wants to be wired on top. Side A
while your front speakers on the bottom rail side B
then both sets should work on your current set up.

we tried that but still no luck, it seems to be the case where you plug the phono into port A and bass comes out for rail A but if you unplug the phono and put it into port B nothing happens at least bass would come from the front speakers. Below in the link iv found the user manual to the headunit, if you look at section 25 on the pdf it relates to bass settings and such like. My proposal is to set the frequence to trebble so that trebble goes to the amp and then change port a to low pass for the bass and rail B to high pass for the trebble?

What do you think?

Thanks

you are only going to be using input a mate and they are wied up wrong by the looks of it. play aroud with the wire positions until you have it and is the it just a sub wired? or a sub and speakers? you only seem to have one pair of wires for the lot! all got to be wired separate

sorry yeah the pic doesnt look that good but on rail A which is the orange cable to you is the sub cable and the other pic with the white cable is for the door speakers. Iv'e wired the cble from the speakers to the boot to be wired to the amp. However its strange its for a mate im doing it for but on the back of the HU it only had one phono output and that goes into the amp via port A and that gives the bass. However we want trebble and bass so if we set the HU setting to High pass or something, trebble wil go to the amp but from there we can seperate port A for sub and port B for Trebble? However its causing some confusion. I even got two: phone 1 into 2 dividers so that from one phono lead we can split the red into two and the black into two, save getting another cable plus you cant put another phono in the back of the HU anyway.

Here is a pdf i found of the HU there is a section on the phono setting and bass setting on section 25 of the pdf. I think it wil be possible to split the signal but how need more experties on this one that why iv'e come to you guy's

Here is the pdf:

Just noticed. Its a weird amp. You have another terminal rail which uve put your door speakers onto. This isnt an output for speakers. Its a input level adjustment of some kind. You need to wire your four speaker cables into the terminal B under the Orange cables.

Ah right with you can see it now. However when we put the sub on rail A (which is the orange cable) and put the phono cable into port A Bass comes out.....fine. But when we put the door speakers onto rail B (below the orange cable and is the white cable) nothing happens. I think we have narrowed it down to being the fact that with only having one phono out from the HU and only being bass settings on the HU it can only be bass out frequency, and that there is no way of getting trebble. It will only work if the HU had more than one phono out of it that way we can divide it and use the subwoofer phono for the sub and the normal phono for the trebble..... and when we put the speakers on the same as the sub bass comes out of the door speakers

FEWWWW long winded

So new HU with multiple phono outs is the way forward
