This amp is great. I have had it for six months without a flaw. It is very compact and sounds awesome no matter what I am listening to. Sonic Electronix had the best deal by far so I would recommend them for all of your electronic needs.

I replaced a terminater 1200w amp with this one because the terminater was overheating frequently. I am totally satisfied. Sound is crisp and clear. The thump my 2x 12" subs make is incredible.
