sub amp box and wireing packages?

[haz_pro]

ah yeah i see what you mean now, maybe i should order the sub and the box from different websites i guess, would a ebay one be bad?

[Ashleyp]

im not sure mate.. i dont really understand boxes and that.. but it would be best to have a custom box.. but obv its hard on a budget (i have the same problem)

so with the sub from bassjunkies £85
wires from caraudiodirect £26
postage will take it up to around £125

ive got one of these boxes, it come free with my sub

however maybe coonper could reccomend a box when he comes online

[haz_pro]

i heard ported is better for like rock music, is this true?

Sealed boxes: For deep, precise bass
A sealed box is best for any music that demands tight, accurate bass. Expect flat response, deep bass extension and excellent power handling. Because a sealed box tends to need more power than a ported box, you'll need to use an amplifier with plenty of watts to get the most bass out of your sealed enclosure. Some sealed systems can give you great bass from a relatively tiny box, which helps you save space for luggage.

Ported boxes: For forceful bass
Ported boxes use a vent (called a port) to reinforce low bass response. You get more output than you would from a sealed box at any given amplifier wattage. Some people prefer the sound of ported boxes for rock, heavy metal, dance or any hard-driving music.

Bandpass boxes: maximum impact!
Bandpass boxes are a special type of ported box designed for maximum slam. The woofer is mounted inside a dual-chambered box, with the sound waves emerging from the ported side. The sound that comes out of the port is extra loud within a narrow frequency range. Because bandpass boxes are super efficient within that range, they tend to boom. Their aggressive sound is great for rap and hard rock.

Free-air subwoofers
A free-air system consists of woofers mounted to a board attached to the rear deck or placed in the boot against the rear seat. The boot of the car acts as an enclosure which houses the subwoofer. Free-air systems save space and have flat frequency response. The woofer must be specifically designed for free-air use.

hope that helps

yeah that helps. hopefully order sub and box and wires soon, want to make the right choice on the box.

yep.. well with the pioneer sub, and that jbl amp.. you should have a sweet system in the making

but people often overlook things like wires and boxes.. no point going for the cheapest option.. quality is whats needed here

maybe buy the sub / amp / wires i showed you

and just wait a little more till you find a decent box?

youll have things laying around in your bedroom for a while.. but better to build up to a quality sound system instead of rushing everything!

failing that.. you could build your own box? im sure one of the people on here who understand box sizes / porting etc will be able to give you valuble advice! and mdf if like £10 from your local diy shop

[Ashleyp]

im actually becomming quite tempted with that set up actually haha

the pioneer sub and the jbl amp will be producing a sweet 1000watts RMS

and only £205

[haz_pro]

yeah thats what i was thinking, im still stuck on the freeking box aha, it would be a shame to ruin a nice set up by getting a below average box! Is the celcus installation kit any good? or is the autolead set better that coonper posted.

[Coonper]

Hi mate!

When you say youve bought the amp is that the gto1201? If so, good lad!!!

This amp will do 1114 rms @ 2 ohms, therefore to get the most out of this amp ideally you need a sub which will handle at least 800rms and to have dual 4 VC's.

Or, if you are struggling to find a suitable sub to take this much power then you could buy a sub with dual 2 ohm VC's, as this can be wired to show 750rms at the amp. Then you would only need a sub which will do around 500rms

P.s. Dont go with in-phase!! They are vibe's sub brand and are cheap and crappy with overated figures.

With regards to boxes... You obviously want it to sound loud, punchy and deep for rock musci. With this in mind i would go ported, however, you cannot design a box until you know the THS(thiele small parameters) of the sub in hand.

If you get in touch with BFUK they make very good quality boxes for about £40-£50. They will recommend you an enclosure size, tuning freqency and the box can be made to fit the boot of any car.

And with that amp, you want to use AT LEAST 4 gauge cabling! 2 gauge or 0 gauge would be ideal, but its expensive. Its one hell of amp!

You can power as many subs off a mono amp as you want. However, if the amp is 2 ohms stable, then you cannot drop below this. When wiring in parallel the reisitance of the VC halves, and it also halves when adding another woofer. However, when wiring in series the resistance doubles. With this in mind, if you were to utilise parallel and series wiring it is possible to get a few options of resisitance. So you can power as many sub sas like as long as you dont drop below the amps minimum stability.

[haz_pro]

Right,

Well i didnt want it for rock music, that was why i was asking so that i didnt get a ported box if it was for rock. I listen to mostly grime and drum and base.

Does the pioneer sub i posted have 4 VC's? as it is 1000 rms and 3000 max so it sounds like a perfect match, is it not?

I think i will have to go with 4 guage, as i am seriously over budget haha.


heres the sub - http://caraudiosecurity.com/shop/pro...s_id/6710.html

[Coonper]

That sub will be pefrect to run off the jbl amp.

However, the sub will just be strangled in that box! See if you can buy just the sub on its own, then get a custom box made.

People on here dont seem to understand the importance of a good box. The box is the biggest factor of how the sub sounds! It makes more of a difference than the actual sub itself!!! Hard to believe i know, but trust me! Its true!

Get in touch with BFUK. They are currently making mine!

And also, ported will give you much much more output(volume) and it is also suited well to d n' b, but this requires a bigger box. How much boot space are you willing to sacrifice?

[haz_pro]

As little as possible to be honest, but i guess if i have to use the space then i will, i can get the sub for 85, plus postage. If i get the box off of the BFUK then will it have the connectors and everything, how hard is it to put the sub in a box and wire it and everything?

How do i contact BFUK, is it a website? i guess it must be worth buying a better box in the long run.

Best off ringing them, cus they take days to reply to emails, when they do! lol

Ask them about the terminals and that, but i expect they will put them in for a couple of quid extra. This will sound awesome if you put that pioneer in a good box! Hope you like loud bass! lol

[haz_pro]

yeah, ill give them a call. Should end up having a good set up hopefully, im going to be so skint hah.

Did you no request the ports to be put in?

how hard is it to wire everything up?

Does anybody know how i would wire the sub to 2 ohms to get the most out of the amp?

Thanks.

Well you tell them situation you are in, what sub you have, what car you have, what music you listen to and physically how big you want the box to be.

I expect they will say...

"we will do you a 2.25cuft slot ported enclosure tuned to 34-34hz"

You will need to know the size of the cut out for the sub as well though, but you can let them build the box, then when the sub arrives ring them up and tell them how big it is. Its normally about 11.25".

Wiring is easy mate, it just takes time to feed the wires through. But you can get the whole lot installed within a couple of hours.

With regards to VC wiring. you will need to wire the VC's in parallel, to show 2 ohms.

This means pos to pos, and neg to neg.

ok, thanks alot mate, if i get a standard installation kit wil it come with anough wire to do all of the system. How big the cut out? woudlnt it be 12 inches? maybe not, i guess i will cal lthem up first and see hwo much it will be, then if the price is right i will order the sub and the box serperately.

Recomend me a wireing kit please.

and, how much is the postage on the box they are making you?

If i wanted the base to be tighter would i get a sealed box?

Well you wanna be using a 4 gauge wiring kit mate.

Like this one. Unless you can search and find one cheaper?

http://cgi.ebay.co.uk/PYLE-1600W-4-A...2em118Q2el1247

You definitely wanna get it ported mate! No question about it
The postage is £7.50, but i think he will do the whole lot posted for about £50.

The cut out size isnt actually 12", as the basket is often smaller than the cone of the sub and in order for the sub to fit tightly you want to get it to quite a tight tolerance. Chances are they will know what size to do it anyway! I mean, after all, they make boxes day in day out and i expect they have done a fair few pioneers before!!

[Ashleyp]

read a little bit of whats happend since ive been gone, but not all lol

as i said mate.. get the pioneed sub from bass junkies, and save £15

the boxes or CAS are shite if you actually care about your soundsystem!

custom box FTW

[Ashleyp]

http://www.rockfordfosgate.com/rftec...1&woofer_imp=4

found that for you mate.. shows you how ud need to wire the sub in order to get the impedance of 2ohms

hope that helps
