Not really. I assume u mean u need a HU that has preamps so you can connect a amp to the HU to run your subs? No HU can power a sub with its built in amp.
Most HU's provide around 15watts per channel. So no you can not power a sub with just the HU's internal amp. U can power door speakers but even that is kinda cloudy as 15watts is not alot of power for any type of speaker.
$350 is awfully close the MSRP of the upcoming new Pioneer DEH-80PRS. NOTHING can come close to it except for used gear, add or subtract a $200 or so, in terms of features:
Ik I can't power the subs or speakers with the hu. I stated my #5 statment^ when I was in class at school. So I didn't really have to long to type it out, kinda have to think fast. What I meant was to run the hu with the amp which then to the sub. sry bout dat bruh
I really don't know a whole lot about pioneer at all. My friend just recently got one of their hu. The one reason that I don't know if I trust them is because they sell some at wal-mart. But I don't really know a whole lot about them. =P just sayin . . . whats your experiences which them?
