Great amp, runs cool, BIG Power!!!
Great amp, runs cool, very power altho was very pissed with installation manual that came with it PMX series which is totally different.
I struggled figuring out which was + & - on the speaker terminals as there are no markings on the amp, there were + & - marks on the amp speaker input plugs. but that is useless since the plugs go into amp either way.
I referred to the manual, but noticed the pictures of the amp were different, then the cover of the manual had PMX-640 on there, this is a PDX amp.
overall very happy with the amp, maybe my luck they put the wrong manual in the box, had no luck finding a manual online either, no birth certificate as only certified alpine dealers supply certificates
