so far ive come up with is a pair of type Rrrrrs for 250

and these pioneer champion series subs Amazon.com: Pioneer TS-W3002D2 12 In. Champion Series PRO Subwoofer with 3500 Watts: Electronics

thanks for the help il look into those AQ's aswell

Don't mess with the pioneers, I've had those before they're decent but not earth shattering. Get a pair of these.... http://www.vminnovations.com/product_3203/Audiopipe_15_Inch_2000W_Subwoofer.html

The ipipe is the same as the txx-apx's and those are known to be budget beasts, hit hard take their wattage and have 3 inch voice coils...

Here are 4 audiopipe 15's with about 500 watts a piece starting to move hair. You would be running half the subs, but in a lot less space With more power..... SHOULD BE PRETTY SICK......
