I bought this amp used.

I finally subs! I had a lot of amp (or new low-end or high-end but a bit old) and it really active all four of my 18-inch subs.

Amp lightweight, efficient and reliable a priori. They designed a real system of self management: permanent control of the power supply against voltage drops, real limiter / attenuator which makes virtually impossible any breakage if it is properly adjusted.

Can be expensive at first but the price is worth it. The manufacturer announced a rise time under a load of 4 ohms 2 times less often to others, resulting in the output signal is very faithful to the input signal despite the burden and power: the lower the better does it include !

In short I do not pretend to buy another but if I needed it so I do it again this choice without hesitation.
