in my civic hatch i got 1 12" MTX sub, the thing sounds great! i love it.
as for the splits up front, i got a pair of 4" pioneers with the tweeters, and i wouldnt be lieing if i told u i cant hear anything coming out of em.. the 6x9's (kenwood 300watters) completely overpower them, and isnt worth the money, considering i payed $140 for the 6x9's, and $160 for the splits.. other than that my system pumps pretty hard
Now these speakers are F#cking awesome, i want em but $$$!
