Some of their other amps use LM3886TF, TDA7293 (both AB) or MPS7720

I must be blind, someone please correct if i'm wrong, but this comes fully assembled right?

Interested in testing one asap.

Hi Andy,

Have you recieved your amp? I spotted these on ebay and was intrigued as to the sound- the price is right.

Hi James
got it several days ago.
i have only bench tested it.
8/4/2
doing around 70watts at 4 and 125 ish at 2.
more importantly was exstreamly good at 20 khz
well better than some so called profesanal class D amps
costing thousands of pounds.
and allmost no chopper products preasent.
very impressed with it and it cost 20 pound so bit of a p take.

Thanks chaps.

Depending on the outcome of sound trials, I will probably get one of these.

I'm new to class D - just reading thru the stickies right now...

This looks like it could be used to power my subs quite well... by the looks of it I could just hook it up to a 65aH car battery I have spare...

Anyway, my question was could I use a balanced output going to this amp, then each sub to 2 channels...

I'm using car subs, so they are 4 ohms each... so could each sub get around 150Wrms (clean) when running balanced? or have I missed something here?
