This amp is great for the price

I bought this amp with 2 Directed 10" subs. and it pushes them very well. Lots of power! this amp is great for the price!

By George on July 13, 2007

Great budget amp

Pushes a solid 300+ watts RMS without any distortion as it has burned a couple 250 watt subs voice coils. Different subs in different boxes. It is also inexpensive. Full featured with high and low pass crossovers, and adjustable bass boost. Nice weight to it which is usually a good sign. Large enough to dissipate the heat it produces. This thing can be turned up most the way and not overheat, although I seem to remember that it will overheat in the summer at full blast. Has been through several short circuits due to a couple blown subs and its protection circuitry has kept it safe. Also has dual 25 amp fuses which 13.5 volts * 50 amps = 675 watts. This is above the RMS power rating which is a good sign. There are 500 watt amps with only a single 15 amp fuse which obviously will not put out what they say.
