good boom boom

I bought it for 229. It works well with factory radios. It wasn't too difficult to hook up either. I like the fact that when you have high level inputs(instead of line level) you don't need to run a remote wire. Power, ground and speaker leads from rear speakers. Plus, it comes with everything to hook it up. Wires, spades and even a remote adjustment knob to adjust the volume of the sub to adjust to each song. The signal from the speakers turns the amp on. What can I say it bumps pretty good and it doesn't take up much space. It can't be beat for the price, size and ease of use. I didn't want a tube so this was what I decided on. Adjustable crossover, 50-250 hz too.
