Rockford Fosgate 401S 1200W two channel Amplifier. Perfect for installing sub woofers for a massive sound system. Bought new from Best Buy a few years ago for near $300 after taxes, etc.

Asking $150 plus shipping Negotiable.

For another $100, will include all the monster cables, Sub Volume Knob, Stinger SCB100 High amp circuit breaker, and capacitor needed to install in almost any car. All lines long enough to reach the back of a 2003 civic EX. All you would need then is a sub (or two) and a box.

For everything: $250 plus Shipping
