350W Class-D Subwoofer Plate Amplifier - High Performance Amp Board Module for Subwoofers

I wanted to put a car sub into a home theater setting for music listening in the garage. Figured I would hook it up to a plate amp. This amp was best bang for buck for its claimed power output. I didn't expect TOO much out of this set up so I built a sub box out of 1/2" osb scrap from work, especially since the sub is dvc wired in series from 2ohm to 4ohm. It's actually performing so well that I now plan to build a proper box out of 3/4" mdf to actually get the full performance out of the amp and sub. This sub is rated at 800w rms btw. I'm impressed with this amp. I've only had it for a month so if it fails I'll come back and update

I installed this in a Klipsch R-121SW and although I had to modify the opening slightly I am very pleased with the result. It sounds better than the oem amp. Hopefully it will last longer than the 3 oem amps I had to replace over the last 5 years. I highly recommend this product.

This is a great plate amp,rather for a diy of to replace a faulty one . I bought this to replace the amp in my M&k 12" not because it was bad but for the amazing amount of frequency control you can achieve with it over your standard frequency and gain knobs. I have two other subs in my av room and all my speakers are Klipsch including two spl 10" subs and this allows me to fine tune the frequencies to match those .

*Important* This amp is not happy outside of 4 ohm. I purchased this for a subwoofer project. A three chamber cabinet with two 4-ohm 10" dual voice coil subwoofers (125-250 watts RMS). Once wired properly (the amp is 4 ohm stable) in series-parallel, this amp drives the subs without much issue. Good product for the price point. Pros: Good frequency response and adjustable crossover While slightly underpowered for the subwoofers, delivers clean sound with minimal distortion. Cons: Plastic back plate. Deforms too easily and is not a good at heat dissipation. Product information is not informative enough and not product manual. I should not have to have had to experiment as much as I did.

I don’t usually write reviews, but when I’m surprised with the quality and what it produces i’d be glad to spread the word in what I got. This plate amp was smaller than what I wanted and not the power I wanted, but was amazed in the low base it puts out compared to what I had the 18 inch proreck give out on me after two years.. I should have listened to the reviews, but had to try one. The program started to make pop noises when I turned it on they would eventually go away, but then all of a sudden it just quit on me no sound if you’re willing to try this out it’s got low base to it. You’d be surprised and the power too I’m pleased with it. we will see as time goes by. I may have to change my rating hopefully not.

This product seems to be aimed at the home theater market, so my use in a music system is not ideal. I've been thinking about returning it, but I cut-out my speaker cabinet to fit, so replacing with something different would be a lot of work. My application - updating older JBL 10" sub used to cover the below 50Hz range in my living room music system. Pros: -Reasonable price - was $30 off the day I ordered it. -Worked when I turned it on right out of the box. -Plenty of power for my use. Cons: -Makes a "zip" noise when I power on and off from my systems main power strip. (Wish it had "trigger in" power control and a time delay relay on the speaker output) -No option to turn-off 45Hz bass boost circuit. Selections are +6 or +12 db of bass boost, but no flat response option. -Auto On doesn't seem to respond to my normal music listening volume. -Sketchy User Guide. No mounting cutout template or dimensions. No pin out wiring info for balanced input or explanation for use of balanced output jack (daisy chain additional subs?) Best for a home theater to create a booming thunder storm IMHO

As described, prompt delivery, my daughter loved it

Very well behaved throughout the bandwidth. No surging! Deserves a good enclosure.
