These subs hit hard believe me i have 2 of these with a crunch 1000 watt amp, and they just kill!! As a matter of fact I can't turn my stereo up really high because, everything just shakes and I cant hear. But, these subs are clear and basically a steal for 30 dollars!!

I have two of these in a custom sealed box powered by a 1000w Crunch mono amp and it sits in the trunk of my S.L.A.B.. It hits nice, loud, and clean inside the car and you can hear it coming a block down. I'd recommend it to anyone.

Customer Testimonial

I did my 1st purchase with SonicElectronix while stationed overseas. No problems. The service was so good and prices unbeatable that I decided to come back. They beat the price of a couple of local shops and then to boot they beat their own price when I ordered. From here on, it's Sonic all the way!
