Review on Sound Storm Laboratories LOPRO10 Amplified Car Subwoofer - Boost Your Bass on Limited Space by Joshua Overacre

Most people looking at this product think that 1200W is a lot and it is. But don't let that number fool you. The actual wattage to look out for is RMS watts. This is usually about half the peak power. In this case, I would say that the RMS power output of this subwoofer is 50-100W RMS, which is quite weak to be honest. I've had this subwoofer for about 5 months now and it's not great. The sound is decent at low volume (when it is), but once you turn up the volume the extra volume doesn't increase past a certain volume level. In my opinion that sucks. But you get what you paid for. I'm already looking for something worth the money.
