Up for sale is my Arc Audio 400.4 KAR series amplifier. I had it run my MB Quart components for the past few years. It is an incredible amplifier, and made right here in Modesto! It is in excellent condition! The newer model runs the same power, but in a new black shell.

I will take $140 SHIPPED within the 48 states. I live in Nor*Cal if you want pickup. Other than that, if you have any questions please ask me. Thanks for checking this out!
