Don't bother replacing just the factory amp. The reason is because the crossovers for the component speakers are built into the amp. If you replace your amp with a nice aftermarket amp, then you'll have a full range signal coming out of the amp. However, you have three way components up front (woofer in the kick panel, mids in the dash, tweets in the A pillar) and two ways (woofer and tweeter) in the rear deck. You won't have the crossovers necessary to send the proper signal to each speaker component. If you really want to keep the factory head unit, you probably should replace both the amp and the speakers. If you're willing to part with the factory head unit then you could replace it with an aftermarket head. You could use the new head to drive the BMW amp and speakers or you could drive new speakers directly with the new head unit's amp section. Or you could do what I did: replace everything!

Many of us has swapped audio components so there's lots of free advice to be had here. Don't be shy to ask!

The sound quality of my factory stereo system has degraded to the point I can not stand it any longer. The sound is very crackly and seems to fade in and out at random. The speakers all seem to be OK, I have treble and bass at all four corners. Is this amplifier or stereo receiver problem. Has anyone just replaced the factory amp with an aftermarket??
