Massive Audio NX5

Amazing 5-channel amp. Pair of RK6, CK5, Extra par of massive Tweets and Pioneer Primier 12". Also how small the amp is easy to place at any location. Nice clean flat black design. I love Massive!

My installation goal for my new 2011 Subaru WRX 5-door wagon was to keep the hatch area open for gear. I decided to try a five channel amplifier mounted under the driver's seat to run an active two way front as well as a subwoofer, The NX-5 came highly recommended on DIYMA so I decided to give it a try. It receives its signal from a JBL MS-8 and powers a pair of Dayton RS180 midbass drivers and Tang Band wideband drivers as well as a Diamond Audio D1 10" sub.
When I opened the beautiful Massive Audio box and saw how small the NX5 was, I was skeptical about clean power from such a small footprint. Particularly with no heatsink fins or internal fans. I have been genuinely impressed, though. Power output is easily as high as advertised and clean all the way to uncomfortably loud listening levels.

As suspected, the amplifier does get quite hot after extended listening, particularly when it was simply velcroed to the carpet (no air movement beneath the amp). Once I raised it off the floor, it only gets warm after extended listening at loud volume levels. The amp has never gone into thermal shutdown, even after once mistakenly kicking a gym towel under the seat and completely smothering the amp.

My buddy has this amp hooked to an orion 12 in a mini cooper set at 1ohm and does it hit or what wow. very impressive only thing is the amp gets pretty hot quick and i dont remember seeing a fan anywhere on the amp, but other than that great amp.

This is a great amp, it does a lot with a tiny footprint. Lots of power, pretty good looking, no bass boost which is a HUGE plus. I'm glad this amp does not have bass boost.

The 4 channel section is 80x4 or 240x2 bridged, the 480 x 2 is a peak number just to clarify. It does still put out a pretty sizeable amount of power. It gets the job done.
