Alpha 60.4 Car Audio 4 Channel Class AB Amplifier, ALPHA-60.4AB

It's a good product for what I'm using it for

I have this amp hooked to 2- 6 1/2 Cerwin Vega , 2 6×9 cerwin vega in back, Alpine tweeters And a 12 inch kicker. Is unbelievable for the price!!! Loud and crystal clear.... I'm buying another one just to use on my door speakers in tweeters. I might even buy a spare. They're only $50..

Amp distort ch 1 & 2 & have me thinking my front speakers are bad, then hooked it up to ch 3 & 4 it’s shuts off after a couple of secs smh🤦🏾‍♂️ bottom line amp doesn’t put out enuff power & can’t handle the small power from simple factor speakers 👎🏾

I have a long history of car audio going back to the late 80s. I have cracked windshields with some of my setups back in the day. So I'll skip straight to the point: this amp for the features at the current price point is an absolute steal in my opinion. I have added a 10" subwoofer to a pinball machine (powered by a AC to DC power converter, not needed for a car of course), and this thing is way more power than needed for my application. It sounds clean and I could not be happier. At some point I do have plans for a car restoration, and since this amp is so overpowered for my current use, I plan to switch it out to power a pair of 10" or maybe 12" subs. So while this amp is not a "competition" level device, again for the money you are going to get some serious power that sounds great. Very highly recommended.

Don’t expect high end quality here. Basic amp for basic car stereos. If you want more noise for cheap, here you go. I’d probably spring a little more cash for a basic pioneer before buying this amp again.

This amp is for the budget minded person and it does it very very well. Is it going to match the quality of say a Focal? No, but that isnt the purpose of this. Will it drive it sub when bridged? If you have a good quality sub it will indeed push it without any trouble. Just don't expect earth shattering bass but it will give you perfectly acceptable levels for normal music listeners.

Cheapest thing that made me place the order in the first place but not regretting my purchase at all. This amplifier has exceeded my expectations and is definitely worth every penny. The sound quality is crystal clear, and the power it delivers is impressive. Highly recommended!

Looks is all it has. This has to be the lightest amplifier ever, in other words no substance.Let's do some amplifier math, it says 480watts with a 10amp fuse. So car running voltage is 14.4V, times that by 10 amps equals 144 watts. Now we have to calculate the amplifiers efficiency. No amp is 100 percent efficient especially class A/B they are typically 55 percent or so. The most this amplifier could possibly put out is 80 watts total, 20 watts X 4.
