This amp kicks out plenty of power to work any speakers. I have 4 Pioneer Premiers running off this amp with no problems overheating or lack of power. This is a great high quality amp.

Customer Testimonial

I bought some Focal speakers from Sonic for $150.00, They are $220.00 in the local stores plus they will rip you on installation.. I put these in myself and I finally felt good about a car stereo equipment purchase.. Plan on getting some more stuff also. Thanks Sonic Electronix.com Your the bomb!
