Sub & Amp

[compress'rolla]

I have a vibe limited run sub that I got off eBay £150 the best for buck iv seen and had. For the wiring I ran my supply (Battery cable) down the left sill and the data (pre-outs and b+) down the right... Space was tight and don't want alternator noise :) and I earthed mine on a bolt under the seat because it's a clean earth. No sanding lol whole installation took about an hour that's with the cd player and all.

Forgot to mention run your sub and amp in for 20 hours so the rubber on the sub doesn't burst as it is still ridgid and so your amp components get used to heating up and cooling before ur bass is up so low to mid volume it hould be. I never and mine works intermittent lol gutted!

thanks for the reply's guys

but here's a quick update guys

today my sub and amp arrived

i started installing it and after i connected all the wires and fuses and everything else, it dont work...like there's nothing

what do i do?

this is the package: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110706119292&ssPageName=STRK:MEWAX:IT#ht_500wt_1156

and this is my head unit: http://www.pioneer.eu/uk/products/25/121/61/DEH-2320UB/index.html

can anyone shed some light on this?

sorry in advance as this reply is going to sound like I'm talking to a kid, but I dunno how familiar you are with electronics and in car entertainment.

1) I take it you've run a fused power cable from the + on the Battery at the front to the power input on the amp?

2) you've grounded your amp to the chassis of the car, on (potentially sanded) bare metal.

3) You've run the L&R RCA cables from the headunit to the AMP.

4) you've run the REM cable from the headunit to the amp.

5) you've wired the sub to the amp correctly as most if not all sub amps I've seen need 2x speaker cable per input (so 4 wires in total).

if all the above is checked then:

is there any kind of power light on the amp?

is the gain at the correct level?

are there any whiskers on the wiring that could be causing a short?

are the fuses hunky dorey?

is the headunit set to output on the RCA's?

also do you have access to a voltmeter?

[corollat3sport]

yeah the power light comes on but the sub doesnt kick in so what else am i doing wrong?

and no offence taken wangtastic, i aint familiar with any of this lol

thanks for your help mate, really appreciate it :D

What wangtastic said +1

[wangtastic]

well it's a good start that the power light is on. :)

so can you take a few pics for me?

I'd like to see:

the amp,

the wiring from the amp to sub (both at the sub and at the amp)

and the dial(s) on the amp :)

if you could mate then I can have a mosey :)

[wangtastic]

sorry to double post but also do you have access to a voltmeter?

[pimp1chez]

i betting a bad earth here , any other bets ?

[compress'rolla]

RCA cables swapped?

[SaraB]

i have a sub and amp for a quick sale. PM me if you are interested

Cheers

[corollat3sport]

right guys, im very sorry for the late reply

sorry wangtastic, i do not have access to a volt meter but i will try and get hold of one

also where is the best place to connect the earth wire with a bolt?

here are pics and if you want any more i will be more than happy to take some more :)

this is how it is at the moment

[wangtastic]

cheers mate you don't need the high input connected so I'd unplug that and put it to one side.

see if that helps :)

[corollat3sport]

thanks wangtastic, i took that high input wire off and there is still nothing?

where is the best place to put the earth wire?

also i connected the purple wire to the HU where it says system remote control and this makes the power light come on

[pimp1chez]

Looks like you have the rite idea so far . if you pull up the boot ,fold down the seat , there should be a cross member running the width of the car ,there should be some kind of handle there ,should be two.

they are used to attach bungey and rope ,to tie stuff down.

if you have them in yours ,sand down all the way to the metal ,and earth there .

if thats not there ,go for the seatbelt anchor ,make sure its solid metal under there mind

[wangtastic]

well because the power light is on it's a good start it means you've definitely wire up the amp correctly (as long as the PROT light isn't on!!)

I earthed mine in the boot on where the luggage hooks used to be:

(follow the brown lead from the Fusion amp)

It's gotta be something on the HU or amp that's not making the sub work...

is your headunit set up to output on the RCA's correctly?

[corollat3sport]

thanks guys

right what will i have to do to make sure that the HU is set up right?

[wangtastic]

TBH I don't know, let me have a look to see if I can find a manual for it.

Bare with...

[wangtastic]

Right so from what I understand there's two stages to this:

1) Switch RCA to SUBW

2) Enable RCA's

so for step 1 refer to page 11 of your manual where it says SW Control you want to set this to the SUBW setting.

Then for step 2 go to page 9 of your manual where it says SUBWOOFER1 and set this to NORMAL.

if you don't have you manual it is here:

[corollat3sport]

:D:D:D:D:D:D.....il explain when i get back!!! lol

[wangtastic]

I take it you got it sorted then?

[pimp1chez]

thats why i only use sony h/.u`s .

dedicated rca sub out ,no faffin

[wangtastic]

exxxxxactly!

TBH all the headunits I've used in the past have had RCA's enabled by default, this is the first I've seen without!

My alpine has everything set from default. plug and play ftw lol

[corollat3sport]

yup every things working fine now so thank you all for helping me :D...really do appreciate it

also i am also surprised that the head unit was not set up for the sub woofer

[wangtastic]

any-time mate :) s'what we're here for
