I've got a resonant engineering se d4 15 inch subwoofer for sale. It has dual 4 ohm voice coils and will handle ~800 watts rms. To power the sub I have a Cadence A7+hc mono block class d amplifier. This amp will put out ~1400 watts at 1 ohm, ~750 watts at 2 ohms and ~400 at 4 ohms. To go with the sub and amp is a 4 awg wiring kit from stinger. I also have a mismatched pair of 6 and 1/2 inch coaxial speakers. One is a kicker ks6.5 and the other is a jl vr650 cxi. The speakers sub and cables have never seen power and the amp has never been abused. Asking $450 or best offer. This is a lot of sound for the price.

Anyone looking for a small powerhouse amp, this is it. Mine is the "silver clamp" version.
