Look else where !
two channels stopped working just two days past return date. contacted Amazon to do an exchange. What a nightmare. Orion sent me a new email asking question’s for three straight days . Finally after that I was emailed a UPS tag and item return number. After Orion had the amp in there hands for over 20 days I sent and email to customer support with all tracking and return numbers looking for a return date. received no response. Contacted Amazon support to see if they could help. All Amazon could do was summit a report to Orion. Not vary helpful.After Orion had the amp in there hands for 30 days I recieved a email with a tracking number from Orion. No other info.They sent me back a amp that was covered in black smoke and dirty finger prints. Not mine! The amp smelled like a wire fire really bad. Now my truck smells like a wire fire.Vary disappointed in this entire experience. Orion sucks.

Punchy Polished Bass!
I just got this amp installed and it functions incredibly well. I use to have a premium lightning audio amp that was a a monoblock D class amp with tremendous output. Unfortunatelly mine died and am going to get it fixed. I tried another amp which was a compact kenwood. TOTAL GARBAGE. I was worried this one was going to sound distorted like the kenwood. This little amp is incredibly powerful! Not only that, but the low bass is super punchy and polished. The 40hz is also polished as well from most amps I have heard. No distortion either I encounted when adjusting the amp and its output. For reference, this is with 2 Kicker Comp C12 subwoofers.

Orion cobalt is just ok
Works well. Don’t really put out that much sound. I was trying to push a skar 12 and it seemed like it wouldn’t push. So I’m not sure about this

Works great. I doubt it’s 4500 Watts but it’s atleast 1600 Watts. Doesn’t overheat or ground out. Pushes two 12 inch subs no problem.

I bought this Orion amp, it claims to be 1 ohm stable, clearly it was not,had the amp wired with a 1 ohm load checked it with my digital multimeter. The amplifier worked in my truck perfectly for less than a week and out of nowhere the amp let out a loud pop and and a large puff of smoke sent it back in August it’s now October 18 and I’ve still not heard anything back from GTA electronics as to whether they are going to replace the amplifier that I purchased
