I installed it in my setup, and the difference was instant and mind-blowing—the lows are tighter, more controlled, and hit hard without distortion. 350W of clean, efficient power that makes my subwoofer come alive. It runs cool even when pushing it hard. No muddy or bloated lows—just tight, responsive bass that enhances movies, music, and gaming. The adjustable crossover, gain, and phase control let me fine-tune my bass exactly how I like it.The plate design makes it perfect for custom enclosures, and wiring it up was super simple. No bulky heat sinks, and it runs like a dream.

The 6db boost was a bit much for a small room. Moved it to larger room, problem solved. Driving an older 10" speaker craft sub and it handles it effortlessly.

As described. You may need to amuse cabinet opening to accept it as I did to fit a keg 400b sub.

Bought to replace a much more expensive Dayton Audio 500W plate amp and I was very surprised at how it handled my 12" amp. Its so light too. No clipping yet either, but I also haven't pushed it hard.

This amp is probably best suited for putting together a custom enclosure and subwoofer, although I've repurposed it for an old unit that died and it's worked well for that. If anything it's completely and wholly overkill, as I do not have a use for XLR inputs and outputs. Having options for frequency cutoff and phase makes it more flexible, though.Auto power off seems to work without issue, as do the various audio tweaks around back. There are no external heatsinks, just a couple of ~0.5cm aluminum plates. It doesn't seem to get overly warm, at least, but that will depend on the size of the enclosure and what exactly you're driving. I'm not having to push it very hard so far, at least.A fully featured amp for building a sub - or bringing an old one back to life, it seems.

Easy set up. Fit my subwoofer fine. Really good price for a 350 watt amp.

I got this amp to replace my existing subwoofer amp that died. This was fairly simple to install. I just had to increase the size of the hole on my speaker box to fit the plate. There are a lot of extra options and control features on this sub more than what I probably need as a beginner. Once it was hooked up, it took a bit to learn what all of the switches and knobs do there was a user guide supplied, however I needed to consult the Internet on how they actually worked. As a beginner this was very easy to install and sounds great. Thing to note, this did introduce a ground fault when connected to the DAC that my computer uses causing a steady hum. When disconnected from the computer and using Bluetooth, it sounds amazing. There are no other issues I’ve had with either installing or using this amplifier.

This should be a great asset for someone building a sub box for subs from 8" to 12", without much issue.The wattage is a bit limiting for anything larger.I have it setup with a 10" Sony sub with paper cone, which is rated for 350w, and it's working perfectly with me home stereo setup.Instructions included are adequate, but it's easy to setup anyways.

I recently installed this 350W Class-D subwoofer plate amplifier, and it’s been fantastic. The power output is impressive, providing deep, clear bass for my subwoofer without any distortion, even at high volumes. The amp is compact yet delivers solid performance, and the Class-D technology makes it energy-efficient, which is a plus. It was easy to install and has a solid build quality. The controls for adjusting bass and volume work well, allowing me to fine-tune the sound to my preference. Overall, this amplifier is a great choice for anyone looking to improve their subwoofer performance with a reliable and high-quality amp

The plate amp is perfect for making a new, or reviving an old subwoofer, to an active subwoofer.Suitable for use in a home theatre or audio setup - not intended for car setup.The size and power is suitable for an 8 inch to 12 inch driver and box.May work with a 15 inch driver if its an efficient driver.This amp will need a 7-1/2 by 8 inch opening to mount.Needs 3 inch clearance depth inside.8 holes for mounting but the mounting screws are not included. The screws needed will depend on your cabinet material and wall thickness.A standard red and black wire lead is included to connect to your driver.This wire can also be disconnected at the board and you can install your own 2-pin connector and wires.This inside is made well with good looking solders and clean boards.Sealant is a little excessive and sloppy but shouldnt affect performance.No external heat sink.The panel controls are very complete with many options and adjustments.All functions are clearly marked.Balance inputs is a nice feature for long cable runs.A detachable power cable is important for upgrading (thicker) or extending (longer cable).Accessible external power fuse.110V or 220V selectable.This has all the features of modern subwoofer amps and more.Performs well if not pushed too hard.

Works well so far.I had two active, Earthquake subwoofers with dead amplifiers.Factory looked at them and said they couldn't be repaired.Wanted $800 for two replacement amplifiers.I wired the two cabinets in series to get 4 ohms and this amplifier does the job.
