Best kept secret!

I bought one B4 for my Harley and then got another for my Jeep. It's small but big on power,clean power. Going to add a B1 to my Jeep for a sub. Amp runs strong and cool and is built very nice. Get some!

This thing ROCKS!!!

I installed this amp in a 2013 Harley limited. It has a small foot print and fits on top of factory radio inside of the fairing. I'm running kicker cs series speakers front and rear. Amp pushes them nicely. Clear clean sound. I would recommend this amp to anyone. Great choice and you won't be disappointed.

Loud and endless power distortion free

This this hauls the mail!!!!! I was skeptical by the size but Cerwin Vega has outdone themselves. This thing sounds better than my last kicker amp that was twice the size and $100 bucks more! I have it running some nice 6.5 inch components and 6x9 in the rear and my system has never sounded better. This amp is a great buy and I dont know how to tell you but I will be buying more from Cerwin Vega.

Buy it don't hesitate

So far this amp has been a beast. It has brought life to my speakers. I was previously using the Rockford Fosgate PBR300x4 that failed. The Cerwin-Vega B4 is producing some serious sound, clear, distortion free, sound. Be sure to buy some capable speakers or this amp will fry them. This little amp puts out a lot of power. Talk to the Sonic In-House Experts they can really provide some great guidance.
