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 .

Bought this to power an old sub that I didn’t have an amp for. Marked and cut out the old cabinet then screwed this in. It was super easy. I can’t say this would be for an audiophile as it has an audible low frequency hum at zero volume. For the money it drives the sub just fine and I’m happy with it.

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

Worked great as a replacement for my 15” Monoprice 41499 powered subwoofer. It took a little modification but I can say my sub sounds better than it did before the original amp went out. I read a lot of forums saying Monoprice will not sell just the amp so you’re forced to buying a whole new enclosure. Stumbled across this and thought I’d give it a try. Worth it!

As described, prompt delivery, my daughter loved it

I have a powered 12" subwoofer enclosure that I use in my outdoor movie theater where the built in plate amplifier got wet and failed despite me keeping it covered (strong storm I guess). So I replaced it with this one. I had to cut my enclosure a little to make it fit properly, but the connections were easy and OMG! I get soo much bass without even turning up the gain very much. Amazing experience!

I swapped out ancient 100w class ab amps for these in my little homebrew living room subwoofers. the power increase is fantastic. the amps run cool. i ran some bass mekanik tracks to run them in hard. i could feel port wind in my chair 15 feet away and the amps kept chugging. no csa, ul, or etl rating on these but the build quality and performance inspire confidence.

Als Austausch für mein defektes Aktiv Subwoofer-Modul in einen HK-TS11. Passt fast perfekt in meinen alten Harman Kardon TS11 Woofer. Ich musste bei der Platine nur die Kanten um 1mm mitm Multitool abnehmen und ich konnte es in das alte Gehäuse einsetzen. Die Leistung reicht bei uns locker für das ca. 30m2 Wohnzimmer. Günstige Alternative zu einem neuen Subwoofer, wenn nur das Modul defekt ist oder zum selbstbau eines Woofers. Die Einstellmöglichkeiten am Woofer sind vielfältig zum Justieren um den Klang für sich einzustellen… Einziger Kritikpunkt, die Auto-ON Schwelle könnte niedriger sein, wenn ich abends nicht zu laut habe, dann schaltet er öfters einfach ab. Das Problem wird aber in zukunft mit einer Master-Slave Steckdose gelöst…

I used this amp to replace a broken one on my Polk audio DSW micropro 3000. I figured going from 1200watts to 350watts would have a significant decrease in performance but I was ok with that. The cost for the original amp didn't make sense. Over all the 350watts was more than an adequate replacement. It works great. I personally cannot tell if there is any difference. The Polk audio sub box is heavy and it does dance around the floor with the new amp. Please note that you may experience a loud hum as many others have mentioned. This is usually due to long subwoofer cable and having the power plug for the subwoofer far away from from the main receiver amp. That hum can easily be removed by putting a simple inline ground loop isolator on the subwoofer cable. Usually they have a left and right channel connections but you just need to connect 1 of the channels and it will work to remove the hum. The filters are typically $20. I used https://www.amazon.ca/dp/B077Y5DLBB?ref_=cm_sw_r_cso_cp_apan_dp_F5DV40GXDDRN0R72QDWM I used a sheet of plexi glass to make an adapter plate for mounting.

Hab gleich 2 bestellt und beim 2, wenn den einschaltet dann fällt die dab+ Antenne aus witziger Weise

I have been using this for a week or so and so far it is performing excellently! I used it to replace the failed amp in my KEF subwoofer which is connected to a Yamaha AV amp. It seems almost better than the original! I did have to make up an adapter plate as this amp is smaller than the original. The only slight negative for me is the brightness of the red standby led, which makes a red circle of light on the wall it sits next to!
