Listen to the install shop. I went through this with Crutchfield. They sold me the PWR-1 adapter from Soundgate. They insisted I needed it. First of all, there isn't enough room behind the deck to fit it. Secondly, there was a constant hiss because of some mismatch with the external amp. I drove around with the hiss for months until it drove me completely nuts. Finally, I went to an authorized Alpine dealer near my house and asked them if they could solve my problem. They took out the stupid PWR-1 device Crutchfield sold me and replaced it with some sort of noise filter. This took them all of about 20 minutes and cost me $40. Well worth it because the hiss is gone. Keep in mind that these guys worked on BMWs all of the time and were very familiar with Alpine decks. I also had the wire harness adapter from Crutchfield that allows the deck to plug into the existing harness. They guys who fixed my stereo said they would have just spliced into it if I hadn't have had that. Keep that in mind when doing the install. If you never plan on selling the car, no big deal. But if you ever want to put the stock radio back in to sell the car, you'll have problems. Sorry for the long post, but I felt that I had to share my stereo woes so others can skip the painful parts. Remember, Crutchfield are not the experts they claim to be.

More opinions I got on this (of course, they conflict):

A different install shop (one that is supposed to be pretty good) says they can wire it into the existing amp w/o a problem.

However, a Crutchfield tech says that I would need something called a "Power Line Level Power Adapter" to be installed to use the existing amp. He quotes the price of this deal at $50.

Any idea on who (if either) is right on this one?
