see what I want is for it to be so loud inside the truck that its hard to breath will 15in subs do that ??
with the limited power you have you need to max out the drivers you are going to use. You want your amp to keep good control of them, while getting them to their xmax. so high wattage subs for the most part won't yeald what you want with the equipment you prsently have.The type-x is more of an SQ style sub (ok SQL) than an spl sub.
Why not get a couple 12" Pioneer Premier TS-W3001D2. I mean **** you can get them for 150.00 a pop on online car stereo.I wish i had the one in my avatar. The ones I have are Pioneer Premier TS-W1207D4 cheap crap.But anyway with what I have to work with two 12in sub might be all i can run because
my amp runs 2600 rms so that's 1300watts a sub thats why I said ALPINE type X
because I can get SQ and still beat hard. And then maby later Ill go for SPL
