ORIONCobalt Series CBA2500.4 High Efficiency 4-Channel Class A/B Amplifier for Car Audio Stereo – 2500W High Output, 2/4 Ohm Stable, Adjustable Low/High Pass, Bass Boost, MOSFET Power Supply

Before I say how good this amp is, I want to identify that it is extremely hard to find the “rms ratings” for these amps. This is the really to measure the power of your amp.So like you, I was very skeptical over the cheap price and I really thought my 3500 watt version (which is actually 170 watts rms x 4) would be very distorted and or wouldn’t get loud enough. I replaced a pioneer 125 watt rms X 4, and man what a difference. My music sounded crisper and more alive if that makes any sense. This a class A/B amp and the pioneer was a class fd. It’s so loud that I can’t turn it up all the way as it makes the speakers pop from to much power and bass. I highly recommend this brand and special this amp. Good car audio doesn’t have to be expensive! :)Make sure your wiring is clean as it’s missing the circuitry to clean the input. But just do it right and buy a “rca filter” and it will solve your issue.

Worth the money.

worst amp i’ve ever had last me 3 days and stopped working please don’t spend/waste your money on this crappy amp one of the worst in the industry

I have been a Orion customer for many years great product that last for years and sound quality is outstanding.

Sounds clean at first start still need to adjust but awesome amp

Got the 2000 watt CBA. It's a decent little amp, just doesn't put out 2000 watts at max. If you've got some lower wattage subs, this amp will work. Watch the heat, it gets HOT. For the price its not bad at all. It is their introductory line I believe. If you want a strong amp go with the XTR line or the HCCA. I love orion, this just wasn't the product I was looking for.

Good

It sounds good but gets really hot. I bought the 2000.4 to run 2 4x6, 2 6.5 & 2 tweeters. Gain 3/4 on ch 1&2 and 1/2 on ch 3&4 has it blazing hot. Running it at 4 ohm w clean electric. (No issues w d4s running 4 12s) This is not what you're looking for. It was a shot in the dark for me. Wanted to try a cheap class a/b amp. And it did very much disaapoint.
