its a JBL 800.1 with a 2008 kicker L7 12". its under powered a little bit but it beat pretty good. i hit 158 DB just can't remember what freq. i hit. i have a bad memory. lol but i had a set of JVC 3 ways 6x9 in the front a set of VR3 4 ways 6x9 in the rear. they were powered by a little kicker 350.4. a 2.5 farad cap and a pioneer advic-D3 head unit. lol also had some little headrest monitors and a ps2 hooked up to everything. pretty nice keeps all the kids quiet. lol but i already got somthing in hers. right now i have a kicker 350.1 pushing a kenwood 12" that i got a best buy. but thats it right now. it beats pretty good. hatch rattles from it so that good with me.
