The RP 600.5!

This amplifier for its size and price pushes incredible power to the speakers and extremely efficient! I have 2 gauge Ground and Power so it gets plenty of power. So much in fact that the dynamic power from the amp is overwhelming to the speakers. I have everything tuned and the tx60 series are not enough nor is the 9 series subwoofer. So I will have to purchase a new pair of six and a half and upgrade the subwoofer to handle this app. Love it! Awesome job Skar!

Great little amp

Nice little amp and packs a punch sounds great thank god I didn’t go with Rockville most Definitely great for the price

Skar RP 600.5

This amp is powering 4 JBL GX 600c component sets and a Skar IX 12" sub all at 2ohm. Plenty of power and a good quality of sound and for the price it won't be beat. Very happy.


I haven't had the chance to install everything I've purchased in the last few weeks. HOWEVER...SKAR AUDIO has been extremely helpful...VERY prompt on sending the items I purchased.....I'm SURE the amp I just bought will be the same high quality as EVERYTHING I've bought in the past. Thanks SKAR TEAM. I'm doing a complete rebuild very shortly. will be running 2 ROCKFORD 1000s. Building a wall in my van with 2 -18s. 2-10s n 2 -12s. 2-6×9s in each front door. Will be GREAT. ROCK ON FRIENDS. My existing system ROCKS. Just time for a change. We will see👍🤘

Great Amp

Just finished installing this amp in my Mustang running 4 SK-68's, and 2 VD-8's. Sounds great so far. I can't wait till the subs break in.
