If you want loud go with the Kicker L7's with around 600 - 700 watts to each. They will take more if you have it. $400 brand new for 2 subs off ebay plus you can get the square trader warranty for another $35 which is good for 3 years
i mean 400- 500 for the whole thing. (subs, box, amp, wiring)
so far: borla catback exhaust, audio swap.
waiting for warmer temps
