Amazing Amp

I bought 2 of these amps and they are amazing. Feature packed and tons of true power. Remote bass knob has clipping indicator which is very cool also.

Amazing amp!

I purchased this amp to push my 2 12" American bass hd's and does this am do the job. This is an amazing amp. I love the bass knobs clip detection and power/thermal/short detection even though I have never used the thermal or short protection indicator it still is a really nice feature. I no others have said this is power hungry and they may be right but in my case I am running this on stock electrical for right now and I drop about 1 volt maybe. But if your going to run 3200 watts on stock electrical how could you not expect that. I am just waiting for my mechman 240 amp alternator and maybe a better battery and I'll be set for now. My plans in the very near future is to purchase 2 more of my subs and 1 more of these and make another custom Midgate box in my 2009 Avalanche. Hoping for a fairly loud set up with that lol!!!! I love hifonics and sonic electronix.

P.s. Only reason for 4 stars is because I received an amp that I could tell was returned. (Warranty seals were broken and had scratches and scuffs on it). But I haven't worried about it because it still works fine but I may try to get another NEW one since I'm still in my 60 day money back.

Nice Amp

Best amp that i've owned for the price...The only thing bad that i've seen is its very power hungry (but thats expected for the size...), So dont try and run it on a stock electrical system.
