Review on Powerful 6 Inch Ultra-Thin Subwoofer: Under Seat Car Bass Amplifier with Low Sound by Heather Welsh

I'm very impressed with something so compact and plug and play. Paired with my Pioneer deck with built in crossover I can send just the sub frequencies to this speaker and I can remove the sub frequencies from the door speakers, get rid of all those broken lows and add a nice hum and crystal clear highs to the doors. Very happy with this subwoofer. This thing is easily worth twice or more than it's worth.
