You can review the specifications for this amplifier at Pioneer's own website here.

This amp has never been used. It does not include the original box but it does include everything that came in the original packaging, including a pristine manual. This is a brand new product.

You can view the product manual online here.

I am also including a Monster Car Audio interconnect package. I purchased it for $80.00. Its specifications are below. It is used to connect the amplifier to your head unit. It is in perfect condition, has never been used, and comes with its original manual.

The manufacturer's suggested retail price is $200.00.

This 4-channel amplifier was built along the same lines as the GM-X564: very low distortion, brick-house construction, and a bridgeable 2/3/4-channel, capability for added system flexibility. The GM-X364's PWM regulated MOSFET power supply delivers high power (300 Watts peak) and provides RCA outputs and speaker level inputs (4-channel). Also, a built-in selectable crossover (see specs) makes the install much easier. Architectural Digest would give it a centerfold.
