Ram Customer –
I wanted to build my own powered sub woofer. I already had the components except for the amp. So I took a shot at this one. Turn out the quality, and power it puts out is way more than I expected. It works flawlessly, was super easy to install, and I couldn’t be happier with it. Keep in mind to match it with a 4 ohm single voice coil sub. And you most definitely won’t be disappointed. So far I’ve built two matching subs. In so in short… They are impressive and powerful little amps.

I had an old expensive subwoofer in my system. When it broke I was debating sending it for repair, which seems to be ridiculous expensive. A newer model would be even more expensive. Since the problem was with the electronic I also did not want to waste the chassis and the speaker itself.
So I stumbled over this subwoofer plate amplifier. Since this one is only a fraction of the cost as any other options I had, I gave it a try. By simply removing the old amplifier and mounting the new one ( needs a small frame I built ) it worked like a charm. Even with the 300W rating it creates a lot of clear sounding bass. This is a perfect replacement when you are on a low budget.
It has all the knobs you need to tune and integrate it into your audio system. Requires a bit calibration to seamlessly work in your audio setup.
It runs also from 120-240 Volts in case you live in Europe. I’m a happy customer now, every penny well spent.
