The bold has me worried.

Plus:

According to the site, it has a 250 amp fuse included. It claims 8000 watts at 14.4 volts, but even at 100% efficiency at 14.4 volts at 250 amps, it would only do 3600 watts. At 80% efficiency it would do just over 2800 watts. It might do what it claims, but I highly doubt it.

Plus the THD is a little high. Most good, high quality amps of similar power have closer to 1% THD from what I've read.

I have never heard of it, but from looking at the specs, it is 2 amps in one case, and the Distortion is higher than what I would normally like to see at rated power, so at 3K Rms it is at 3.5% I would normally not get a Class D amp that is above 1%.

Its says it does 3000wrms (8000max which is irrelevant....)

[CaptainzPlanetz]

I guess I was right about it being 2 amps in one case, Like the AP3000, Oh and this made me laugh in the link that the OP gave if you scroll down to the bottom that has the customer reviews some guys says he has the amp hooked to his Sonys LOL.

[Mikesmith0890]

it only claims to do up to 3400 watts not 8000......

[Marlo Stanfield]

The case and internal pics look very very familiar, can't quite remember to what though.

But that amp only does like 3k and the price tag is astronomical.

[immortal_82]

Yeah... I agree that all your comment... the quality of bass sound is low but still come out 3000watts RMS@ 2ohm

[HHR Ed]

looks like an older stetsom 6k or 7k type design. Those amps were kinda fragile. Its actually 2) 1500w amp boards side by side in one case.

Actually, thats like the older Hifonics Colossus design too. Which was a fantastic amp that did 3200w
