My friend just got one of these in a 6 cu ft box in the back of his 05 Acura RSX and belive me when I tell you it SLAMS. It can't do the quick hitting bass but hard hitting and deep bass, not gunna lie it hurts a bit. He has an 08 ZX500.1 powering it at about 650 watts rms. Kicker is the best quality for the price, easy.
most bass ive herd so far from one woofer i have it in a pt cruiser hooked up to a 750 kicker amp at 2 ohms and this thing thumps rattle store and house windows all the time
I got two of these in a sealed box being over powered by two kentwood 1800 watt max amps and these beast are still power hungry... Igot a red top and big 0 gauge wire. your teeth will rattle, you cant see straight these are the best
Got one of these in a 95 singlecab chevy. Yes a singlecab! It is pushed by a 2200 watt power acoustik amp. It is behind the seat and it slams. I knocked pictures off the wall. It is packed behind my seat but still slams. Love this speaker.
