Review: Compact and all I needed! - Powers my 10 inch home theater car subwoofer with the right amount of power. Easy to adjust gain controls and is powered by a 12 volt power supply I also reviewed on here. Great match of power, small and compact. Well worth the money. Sound quality is punch and perfect for my subwoofer. Took 10 minutes to install and works great!
Review: Surprisingly capable amp - The amp does work and works very well for the size and the price. It's strong enough to push 2, 12 inch subs. The only thing to note which I did not till after purchase is the fact that this amp does not have a bass boost feature. The adjustment knob works well but the bass is limited to out of the head unit/radio.

## Features

- Car audio amplifier 450 watts RMS at 2-ohm load (14.4v); 300 watts RMS at 4-ohm load (14.4v);
- Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry
- 2-4 Ohm Stable - Able to continuously power loads of 2-4 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
- Engineered to be the most efficient car monoblock amplifier in its class so that you can get the most out of your vehicle’s electrical system
- MOSFET pulse width modulated power supply and proprietary heat dissipation design will ensure the amplifier for car subwoofers runs cool for even the most demanding playlists

### ⭐⭐⭐⭐ Good for now.
*by J***A on October 11, 2025*

Just installed today so we’ll see how long it last. Hits my 12” really hard and I only have the bass knob up half way and this sub was used on a different and bigger amp also. Used with a factory radio and with a kicker line out converter with the auto on feature with rca cables. Has plenty of power and output and didnt try the amp inputs because I already had this setup. Make sure to play around with the knobs I think all the way to the left was the setting for a sub high and low frequency.
