Sub Problem

**CraigoT** · 2nd February 2012, 21:37

Well about a month ago i fitted 2 12" subs and they worked perfect, a few weeks ago i had a few problems such as the ground and power wires coming out the amp when i was moving the seats up and down.

So today i decided rather than just put it all back together the same and keep having this problem i moved the amp to the other side of the car so the wires had better fitting and less chance of coming out.

But now i can't get both subs to work at the same time, i have the amp at the side of the sub so there is a short set of wires and a long set that goes round the back to the other side. Only the short one seems to work and if i turn the sub around and change the wires i still get the same. So both subs do work but only down 1 set of wires, could it be as simple as the longer wire is broken i dont have any type of wire to cut a new bit and test?

could be as simple as broken speaker wire
are you running both channels on the amp left and right
if so have you checked the shorter wire on the opersite chanel and the opersite for longer just to rule out blown channel or broken audio leads

i didnt think to change the wire and try it the other way, il go see how cold it is outside and maybe try it now

ok so i just went out and test the problem a little more,

I have a "working - short" wire that if i put that in the red circle it doesnt work and just makes a popping sound to the bass of the music but its not very loud but if i put the "working - short" wire in the green circle it sounds and works perfect.

Now the "broken - long" wire doesnt play a popping sound or the music its just silent as if its turned off and it doesnt matter if i put it in the green or red circle.

im sorry if this is hard to understand

so long wire is broken somewhere along the length
but the red circle shouldnt be popping so in order to rule out if its the amp is to swap the audio in left and right if the popping sound switches to the green and the working one to red you know you need to fix or replace audio in which is from headunit to amp
if the popping stays on the green sounds to me like the channel on the amp is broken

sorry if it a stupid question but

Does this just mean swap the rca leads so they dont match like red to white and white to red on the amp?

yes just to rule out damage to the channel on the amp if the popping sound goes to the oppersite side you know its the leads/rca

right i swapped them over to the wrong way and the red one started to play like it should and the green didnt work

so does this mean i should get new rca leads and a new wire to replace the longer "broken" wire?

yep new wire and a another speaker wire better than a new amp
went through a few myself when i use to have amps and a wife throwing a buggy in the back
in the end i bought new jack plugs and use to solder back together when they broke

try some new rca leads, if thatdoesnt work then id guess that you left the battery connected as you moved the amp and youve shorted the rca to the head unit... this is likely to damage the rca fracks in the head unit. if its a pioneer they have protection for this and can be a cheapish repair.... if you're running a line converter then you may bave fried it...
