I purchased this amp cause my other one wasn't strong enough for my set up I'm running tx 6.5 & 5.25 in my doors and got a custom rear deck with 4 6.5 midbass with tweeter and it's super loud and amp gives amazing power to run all that will be ordering skar midbass to replace the ones in my rear deck real soon

Good amp for a great price!

I have this amp running 2 sets of Skar components, on channels 1/2(wired down to 2ohms) and 8 coaxial speakers, on channels 3/4(wired down to 4ohms). Amp does get hot, but hasn't shutoff yet. Nice build quality. Only complaint, it was missing the bass knob and remote. Very pleased with it. Check it out on my IG@210.designs
