Good Bass, expected a little more but adequate

Need to check on fit, installed on 2006 Wrangler TJ Rubicon and seat will not latch down, not good when people are sitting in it, maybe it's the seat cover but the Wet Okole's were as much as the sub's! The amp is a little underpowered, the guys should match the amp to the capabilities of the more than adequate subs. I'd rather have too much and turn it down a hair than have to fine tune everything to the decimal point, you really need to boost through the head unit, if you do you will be happy! In all a good product if I get the back seat to latch. As far as Sonic Electronix goes, great company, fast shipping, super customer service! will order from them again!
