Sony XM-475GSX Car Amp

Pros: Good outputs, and the list of features goes on and on!
Cons: Possible line-noise problems

If you're just powering door speakers, this is a great amp! Delivering 75 watts RMS to each channel is nice, especially if you like to blast your music. The built-in bass boost, and high/low pass filters are VERY nice features, and having high-volt inputs that don't require an adapter can be a god-send for someone who wants to keep their factory deck. The only issue I had, was that after installing my new amp (an Alpine MRV-F450) I noticed that the speaker hiss, and sound of CD spinning through the speakers was gone. However, it may just be that the new amp has some kind of noise reduction.
