hey guys,
This is my 1st post, and yes i already have a problem.....
yesterday i installed my 2 subs and amp but when i went to test em out there was nothing.. all the wiring appears to be correct (i even had a mate look at it) but now none of my speakers work (rear and front).. my 1st thought was a blew a fuse but i cheaked all the fuses and they are all fine... then i unhooked the amp and subs thinking maybe that they were cousing the problem but still nothing.. i am stumped

any help would be great
thanx..

Welcome...

Check wiring,

POwer to headunit?
Power to the amp? rca's pluggd in both ends?
RCA's plugged into the right output? check FAD/BAL settings on headuinit
RCA's plugged into the right input?
Check gains on amp,
Check lowpass/high pass filters on amp
Check crossovers? wirirng all correct?
speakers? Wiring correct?

Trace it back ,it 'll be something simple most likely

Try pluggiong an ipod straight into the amp.

thanks for the fast reply..
yeah there is power to the head unit and the RCA's are in correct.. the speakers were working before sub and amp install but ill have another look at it 2day and look for wat u said..
thanx

Is it a Pioneer headunit? Might have blown the track fuse inside it.

I'm not sure what effect blowing that fuse would have exactly but maybe its worth connecting an iPod or something directly in to the amp like Tim suggested just to make sure they're set up properly and working. Rules stuff out one by one.

hey, i just checked there is power getting to the amp,would pluging an ipod in via the rca cable work?? and no its a kenwood headunit and i check the fuse on the back of it and it looks fine and i replace all relevent fuse's any way still noting but ill try pluging a ipod in to the amp, thanks again for ur help

just checked power again and noticed that the ground wire wasnt doing the job so i took it off and put it on another bolt, then everything was working fine until i turned the volume up a bit (like by 2 or 3) then the speakers went off but the subs are still goin? again checked the fuses and wiring but everything is fine....

thanks heaps for all ur guys help
sorry for all the questions

Sounds like head unit is going into protect mode.

redo the ground wire on the head deck run it somewhere nice with a good o-ring connector

thanks guys i finally got it working...
