i've heard OF THEM, and i remember seein a sticker on a Bass loaded car at a "Cruise" that vibrated my chest :!: .
i've also seen their website. and the Amps' Stats look like they could Launch a rocket into space.
i was going to buy from them ON EBAY (for their good deals) [direct website prices are still pretty steep].
But i ended up buying from ICE DOG (ebay-member).
Buying one of thei amps, means you have more money to spank on a Decent SUB, and you will need GOOD ones to handle all that power.
(8000w peak on their biggest amp [almost a metre long])
if i had a second chance, i would try Loudest.com out for CLASS D amps.
Make sure you get a good POWER-CAP, at least 1Farad per 1000w amplifier power, (Not RMS Power).
the brand of Power-Cap aint as important as the FARAD rating.
(FARAD = amount of power in reserve)
