Speakers popping

So Ive looked and searched the forum and i haven't been able to find anything to fix my problem.

2003, 3.0, Top HiFi.

Radio turns on but all i hear is popping noises from the speaker behind my head (not the sub). All of the fuses on the fuse card and the fuse on the amp are good. i bought it broken. I tried disconnecting the battery for an hour, but it didn't do anything.

Any other suggestions? I think the amp is broken, but i dont know how to check. Should i check for continuity in the amp or speakers? I checked the price of a new amp and its $1200.
 
An aftermarket amp would work and cost a 1/4 of that price. You could fit a whole new system for less than that. Cant help with the popping though.
 
An aftermarket amp cannot be a drop in replacement for a Top HiFi amp. A new system is actually the best recourse for a bad amp. Be sure it's not the speaker itself before going through great lengths.

really ? On my last car i kept the standard head unit but upgraded all the speakers along with an underseat sub, i amped the speakers separately aswell as the sub straight from the hu could this not be done on a stock system ?

I would not define what you did as a drop-in amp replacement. What can be done depends on which "stock" system one has, there are 3 different types. The top hi-fi system amp is driven by a digital signal, the wires in the boot cannot be used for an aftermarket amp. You could connect straight to the HU though. The other issue with top hi-fi is the subs have unusual electrical requirements. Of course if you replace them with something conventional, a conventional amp will work as well.

@JohnnyC - To test the speakers, obtain some device to output sound to the speakers, a home audio unit will suffice. Refer to this site to identify which pins at the amp are for which speakers: http://www.bmw-planet.com/diagrams/release/en/e85/index.htm

Remove the speaker connector to the amp and supply an audio signal to each speaker in turn. You will likely find they are fine. The fault then would either be the HU or the amp. I've heard of amps going bad, but not the HU, but I suppose it's possible. As long as the HU is outputting a signal that can be used by aftermarket amps, you best course of action would be to decide which speakers you want to drive with new amps, as you probably do not want 10 channels worth of amps, nor the over priced mediocre OEM one. If you still want a sub, you'll need a new sub speaker and amp, because as mentioned above, the current subs will not perform well with a conventional amp driving them.
