15'' Sub question

not really. sounds like your plan is good. I recommend 10's over 12's any day. They sound better IMO. many will argue otherwise, but I have installed more systems than I can count too so I would say I am pretty qualified to make a that opinion though Hope it works out for you

 

Agreed ProForce! I prefer the accuracy of a smaller driver. I have JBL 8" in my wife's civic with an old school RF 360a2. No one believes it's only one 8 until I pop the hatch!

 

Hmm... I was very close to buying a 12 and just putting it on the floor behind the drivers seat until I remember'd my truck got broken into a few weeks back (they took my coin tray and a flashlight). I've never heard a bazooka sub before, are they any good?
