Why did you choose this?
Sonic Electronix Store
Loved the brand since the 80s
Ernie R on Aug 31, 2015
Small amp to put under seat cause room is lack of in a truck.
Mark L on May 24, 2015
My stereo installer recommended this to go with my Cerwin Vega Stroker amp. The small form factor makes it easy to mount and keep out of the way while delivering all the power I need to drive my components and coaxl speakers

Is it possible to wire directly into speaker inputs by cutting wires at harness prior to RCA inputs?
Chris c on Jan 14, 2015
Best Answer: Hello Chris,

I think what you are referring to is "High Level Inputs" , if so then Yes. However, no cutting of RCAs is necessary, because Cerwin Vega ships the B4 with a 'High Level Input Harness', pictured below. Is this what you mean?
