great amp. their is a reason john has owned 3 of these. I haven't hooked mine up yet. But I ain't worried about it. I know these things are solid.

$800 for nearly 8,000 watts is sick for the price

its an electronic. electronics break. especially when people misuse them. The previous owner for all you know could have improperly mounted it, ran it at .15 ohms or so many other reasons.

The guy mounted it to his box and broke the legs of the outputs etc.

Broken output legs are a common problem for the rd amps. D5 and d9 have same problem even when not mounted to box. Interested in 2 custom Incriminator 15's built for 3k+ each as trade? Suspension still stiff as hell 1 has fresh recone that's never seen power (had coil rub when I got it so sent bit back do fresh recone. Coils look and read good dual 1. Tons of upgrades and additions.

Yes,and sounds amazing..Kinda one reason I dont want to get rid of it...I know its a bit overkill for a single 15 but ive had a few different 7ks on it and always regret selling them..I cant keep every amp tho and need to move on....

If you change your mind man let me know. Could always run one and keep the fresh one for later :) glws though. Love me some rd's especially after the legs have been re soldered.

Well I dont think they are made for 7k daily but it can take it in burps no problem...atomic rates them at 30k burps..its just a noticeable difference between a 5k and 7k..Thats why I dont wanna get rid of it.

Well heres the ratings for the memphis 16-mcd4kw
MOJO Series Monoblock Class D 4000W Max Amplifer
RMS Power Rating:

4 ohms: 1000 watts x 1 chan.
2 ohms: 2000 watts x 1 chan.
1 ohm: 4000 watts x 1 chan.
Max power output: 4000 watts x 1 chan.

Heres the ratings for the RD-
RMS power, .875 ohms mono 7500w X 1CH RMS power,
1 ohm mono 6000w X 1CH RMS power,
2 ohm mono 3000w X 1CH RMS power,
4 ohm mono 1500w X 1CH
Since its almost identical to the atomic 7k which is rated at 7k@1 ohm I think they just changed the ratings a little.In my opinion if its 7500@.875 it should be closer to 7k@1 like the atomic and cactus..Not 6k..Either way its a powerhouse!
