Amp or speaker or speaker wire problem?
« on: 15 February 2009, 23:56 »
So not had any problems with my setup since doing it 10 months ago. 2 components, 1 subwoofer and a 4 channel amp. Now tonight I noticed the sound on the left hand side wasn't great, it was quite quiet, but came back in to normal sound again, but then went back out, this would happen every 5 - 6 seconds. The sound compared to the right hand side it is defo wrong.

Now looked into the boot and realized the sub and amp had fallen over. Put it back up, and it worked fine for 5 mins and started again doing the above. Now I don't know if it's the speaker cable itself, the RCA cable, or the speakers or amp?

What should I do?

See if it is the speaker and not the amp by putting the sub to the front channel, see if there is a change. Wire your sub to the front output on the amp.

I take it you have a RCA for the sub? Is it non-fading? if it isn't swap the RCAs around, Sub to front, and front to sub.

Yeah I got RCAs for front speakers and one for the sub that run separately. The only problem is the sub is on a bridged channel, surely putting it on a front channel will give it decreased power resulting in a poorer sound anyway?

Would it not be worth putting the front left speaker onto the other terminal (right)?

What do you mean by non-fading buddy?

What is the amp?  Don't bridge the speaker just wire the front left to rear left. See if it goes quite.

Is it just one speaker, sub?

Swap the RCAs around

Sorry I forgot it was one speaker not both sorry.

non-fading is a channel on the HU that does not have a bias. Have you used the "rear" RCA ports on the back of the HU to power the Sub?

The sub is an Infinity Reference one. I see what you mean now with regards to the wiring to rears.

I haven't used the rear port as the HU has RCA ports for front, rear and sub.

It's a JBL GTO1004e 4 channel amp.

So if I first wire the front left to the rear left, and see if that goes quiet? If it does what should I do? If it doesn't go quiet?

Also swapping the RCAs around on both the HU and amp is that what you mean?

If it doesn't go quiet then it is the amp/hu or could be the left front RCA (White).

So put it all back to normal (Front speaker to Front on amp) then try swapping the RCAs around on the Amp, this will tell if it is the amp.

If it does  go quite it it could be your speaker grounding its self out?

I'm either tired of stupid but typing this is even confusing me.....lol

No it's cool man, you're making sense :) I'll give these a try tomorrow, I hope it's not the amp as it's out of warranty now :( then again I hope it's not the speakers as that's the same, damn I'll be paying £100 either way tbh lol!

I swapped the two front speakers around this morning and all seems to be ok now :) Is it possible there was a loose connection?
