Amp is loud and clear. Running 4 6x9's and 2 6.5's. Gets hot after awhile and cuts out, but I'm torturing it. Bumping full blast everywhere I go..no breaks even at red lights. Only time I really turn it down is when I see a cop. Lol. So I'm not disappointed at all. I'd buy again.
Bought 2 the first one had a dirty signal on the number on channel. Blew 2 right front door speakers. Luckily I had more. Swapped to the second Rp150.4 and no problems. Crispy highs and kicks I feel in my feet. Pairs great with the Rp 2k on my subs.
