Love it hook up little amp heads turn

People think you 5000 watts to have bass that not real I have 600 amp you can’t sit car

Still sounding good

I purchase two for home theater Duty back in December they are ran by a 500w RMS plate amplifier still shakes the entire house

The box is very well constructed, the woofer however... in

I have a RP.1200D and set the gains appropriately (knowing this amp is capable of 1400rms dynamic) and i blew the first sub in just a few days. Coil came apart and i knew warranty wasn't an option. Thinking maybe just my own mistake I ordered another from D4S to replace the fried one, went to a local shop and had gains set to about 450watts on an AMM. Let it be for a few days and went back and set the gains to about 650watts and it lasted a while until a song was played that has a constant 37hz throughout the song and it blew again. Not in impressed with the sub but the box was worth the money even if the sub sucked. I re plated the box and installed a sundown SA-12 and it bangs just as hard thanks to this box!

Best budget banger!

This get down for how cheap it is!
