There is nothing wrong with the amplifier. It works fine. If you are looking for a lot of power, this is the amplifier to get. MTX does not make these amplifiers anymore! This was and still is one of the BEST amplifiers on the market hands down! It packs some serious punch! $350, not including shipping; this amp is heavy. Paypal fee is not included either.
