I would recommend these to anyone looking to feel their music but not rattle there car apart. Running about 100 watts @ 4 ohms and it has an amazing sound quality. I can push 400 watts no problem but it shakes my windows. Not bad at all.

Overall, decent subs for the cash (I bought a pair). DVC so alot of nice wiring options. Voice coils durability not up to par with sub (hence the 3 stars) and blow fairly easy. Really sucks because everything else on the subs seem very rugged and as good as the amps MB Quart makes (there amps are awesome). But for the price I can't really complain. I have the ONYX series subs and amp system going (soon to be speaker system as well) and they are the perfect fit. Would recommend for anyone looking for the BEST value for cheaper subs.
