Like it says... Im not much into bass, but an 8" is perfect for double bass drum hits to rumble a little and my pioneer 6.5" speakers arent cuttin it. my cars all wired up for sub/amp so itll be good to go. I just want an 8" sub, dont care what brand really... it doesnt have to be pretty either cuz its gunna be tucked away in my ginormous trunk! lol... If its got a build in amp, like a bass tube, thats a plus... but if you got an amp for it, thats alright too... It can be in a box or not, but mind you Im only lookin to spend about $40... so theres the price, name what you got!
