Pioneer 12's? Right now, I'm looking for a system for my 2008 Dodge Ram Quad Cab.. Obviously, the best place for subs is under my rear seat.. I already bought a box for 2 12's from Fox Acoustics which gives a total of 1.8 cubic feet.. Right now, I have two Memphis M-Class 12's in there.. Not enough air space for em... I'm selling the memphis system and need something else.. I was looking at 2 Rockford Fosgate shallow mounted 12's being powered by a Kenwood 9104d amp, giving the subs ( by what Kenwood is saying it gives out ) 450 watts a piece running at 2 ohms. The subs are rated at 400 rms.. Sounds good.. But now, I'm hearing alot of hype about Pioneer's shallow subs.. Now, I just need to figure out which way to go would be best, before I buy something and not like it.. Thanks.
