12V 600W Subwoofer Board Bass Module High Power Mono Channel Car Audio Amplifier Board, Powerful Bass Car Audio High Power Amplifier Amp Board

Works better then expected

I haven't tested it yet. I'll update this when I install it. I plan on using it to power an old 8 inch Legacy subwoofer. There is no way this thing pushes 600 watts. Even if that's max that'd mean ~300 rms. No way it'll do that either. Hopefully it'll do 150 @ 4ohms. Posting this though because it says it needs a 20A fuse and came with a 30A installed! No biggie, swap it out, but it was in there extremely tight. As you can see in the picture, it broke. Thankfully I could get the guts out with pliers and get the 20A fuse in there. Just wanted to mention that, not sure if it's a QA problem or just the manufacturer hoping to get more juice out of the components. We'll see how it does in a week or two when I get my radio system built. Hopefully it does the job!

I’m gonna start off by saying it does work but!!!Basically the switches junk. It doesn’t work right and I have mine glued down into the right corner so that the low pass filter actually works and functions. The level knob only works from halfway up to full tilt and if it’s in full pass, then the knob doesn’t work at all. There’s no volume to it. However, the low knob works fine. Seems to be putting out around 33 Hz at the lowest. And 300hz on the high with it saying 30 to 280 I feel that’s close enough. This product does work, but it is finicky and I would not recommend putting it in a box. It’s gonna vibrate a lot. it also came in just a plain box with no cushioning so I’m 100% sure that it was thrown around in shipping. And I added another picture of where the speaker cable goes in for the ones still looking to buy it’s worth $20 but if it’s over $25 don’t bother there are thousands of better ones for that price range can’t wait for a V2 of this cuz they have a good start here

well i made it a nice home in a box i built with outpit spring loaded amplefier terminals only to never make a sound, there is nothing to say you can only hook it up one way clearly marked but no sound
