Hello all,

I've just bought my first Scooby - a 01MY WRX - and one of the first things I've done to it is fit a new stereo. I've put in an Alpine 9831R in there, largely following instructions from this forum. I've also put in an old Rockford Fosgate amp from my last car (GTi-6), which is driving a sub and the front speakers.

I thought I'd finally got everything wired up properly, but when I turn the head unit on, a horrendous "THUNK!" noise comes through the front speakers. What on earth is that?? Can anyone suggest where I may have gone wrong?

Cheers,
Phil

 

is your amp a 2 or 4 channel? did you try disconecting it from the front speakers and c if the sub does the same.

 

Take out the Girls Aloud CD and throw it away..

 

There are no Girls Aloud albums anywhere near my car!

Also, it's a two channel amp. A mate at work has suggested that it could be because the amp is attached to the constant 12v wire and not the "remote switch-on" wire coming out of the head unit. I shall swap 'em and try that out tonight.

 

Okay, that was it. Fixed!
