But that said, it is decently punchy and can keep up with the mids/highs of the factory setup. Low end is a little lacking, but anywhere north of ~60hz it's pretty solid. For the amount of space it takes up, it is a great option for sure. I am glad my truck came with it, though it was tuned so badly at first, I didn't even know it was there. If you are interested in how I re-installed it check out my thread... I redesigned the factory CD changer/BT/etc brackets to hold the BSW amp so it looks like a factory piece.
