Exclamation Audio! Help!

I jump started my 01 x5 4.4i and all of a sudden my speakers have a loud noise like if it was on an unknown radio channel, I have a Lear amp hifi dsp! Did I blow the amp? Or speakers? Only the front tweeters work. There is no water damage in trunk at all, and there is no other problem with the vehicle the jump start ONLY affected the speakers so I'm not sure if it's the amp or the speakers.

something definitely fried inside the amp... the amp is designed so it takes basically two input channels (left and right) and transfers them into 12 outputs... you would need to narrow down to specific speaker(s) that stopped working... the troubleshooting might be rather extensive - you would need to tear apart the left side pocket area in the trunk, to gain access to the amp... and then use the amp pinout to troubleshoot each channel - use your third party speaker to connect to the amp and see if the sound is distorted, and then use a sound signal to send down the wires to the car's speakers to see if the speakers can reproduce the sound...

based on your description that the multiple speakers are malfunctioning, i would suspect that the problem at common point, which is the amp...

what is the exact date of manufacture of your car?

Exact date of manufacture is 05/01
And it's all the speakers including subwoofers EXCEPT dash tweeters. I tore the trunk apart already anyways and I have the amp in hand wasn't that hard to remove with proper tools! But I don't have a third party speaker or any of that. So it's probably the amp? Should I just pay to get it repaired?

No that's difficult and can't read them is there an easier way or is this the only way to check the amp?

This is how I would proceed with the amp testing. Maybe there other, simpler methods I don't know about. Try replacing the amp, maybe it will take care of the problem

As side note I highly doubt speakers you can blow from jumping a car something like a amplifier or head unit finals are more subject to spikes in voltage/amps.

those DSP amps aren't cheap either...do you have a good salvage yard or 10 nearby to search for the proper DSP amp. A 5-series amps will work, but you have to get them recoded by someone with a DIS as the adjustments are all wrong for the X5 if the amp came from a 5-series (E39 M5's all had DSP).

If it is toast, you might want to just go aftermarket, but that's not cheap either...nor is it simple with DSP vehicles <sigh>
