pioneer avic-d3
stock bose speakers (absolute crap)

tentative upgrade:
mb quart premium PVF 213 - 5.25" components (front doors)
mb quart premium PAB 2100 - 2-channel amp
mb quart premium PWH 302/304 - 12" 500-watt rms sub
mb quart premium PAB 1200.1D - mono amp

any feedback on the mb quarts? should i do rear door/deck speakers as well and go with the PAB 4100 (4-channel amp)? will these components fit? is this even the correct amp for the sub? should i go with two subs?any other suggestions?<ul><li><a href="http://www.mbquart.com/en/produkte/car/premium/">http://www.mbquart.com/en/produkte/car/premium/</a></li></ul>

My personal experience and opinion with the MB Quart subs is a definite recommend.

Yes, the components will fit.

If you have the extra money, change out the rear door speakers as well, and use the 4 channel amp.

Do it once, so you won't have to re-do it later.

Yes, that's the right amp for the sub.

No, you won't need 2 subs.
