Looks like one of those too good to be true deals, but is perfect size when you have no room in an mr2. My only issue is i can not believe that they get time much wattage from that size, let alone no heatsink. Thoughts?

Output power: RMS 75 Watts x 2CH (at 14.4V DC)

peak power is 250w per line.

in reality it will push out a continuous 75watt per line

meaning of RMS power

generally those Chinese amps are get what you pay for,

In saying that i ran a v12 "1400w" actually 300w

that powered subs up great with very little distortion but was terrible on speakers.
since the mr2 is so small i found running speakers off the head-deck to be perfectly acceptable and just run the sub through a amp

I'm running 8 speakers & two 12" subs off two biggish amps (about 8 year old Sony Xplods) mounted in the frunk! Yeah a bit of overkill, but sounds awsome & I can still fit the spare!
