AMP connection problem?? - BMW Forum

So here's the problem. I have no brains when it comes to electronics...I had to remove my sub box (w/ amp) to get to my spare this past weekend....went to install the wires back into the amp again and.....nothing!

The only thing i can think of is that when i first touched the power cord to the amp, the negitive and positives, were lined up wrong, b/c i heard a crack from the contact. So i flipped it around so that it plugged in correctly, finished connecting the inputs and such, and.....nothing!

Anyone got some tips for me? I didn't think this was such a big deal, but now i'm pi$$ed.

PS. The system is a single Rockford Fosgate P3 10 in. on a 400 W Presion Power AMP, and yes...a restrictive stock deck.

Thanks

if the amp was installed by a reputable dealer, check by the battery (within 18"), there should be a fuse holder and i'll bet that fuse is blown. the crack you hear may have been from the internal capacitors charging and thats normal. good luck and post results if that doesnt work.

hope that helps...

That makes sense. I'll give it a try

Thanks

So it turns out it was the fuse. Only one problem still...the sub's working, but defintly not hitting as hard as it used to. It used to rattle my licence place cover like crasy, and now i got nothing.

Is it possible that the bridge was disconnected. Its a 2 channel 200W that i had bridged to make 400. I've checked all the settings on the amp, and they're exaclty how they were before all this happened.

Just in case it has anything to do with anything.....i have the system running with a seperate sub-bass control knob...?...

Help me out!

Thanks
