Had this Bazooka subwoofer installed in my '04 silverado(single cab). With limited space having the amp built-in to the subwoofer really helps conserve space. I had it mounted behind my driver seat and still able to slide seat all the way back and lean it back just like i had the seat before it was installed. First time i turned it up i just started laughing because the sound was so amazing. I'm only running it at about +2 and it goes to +10 so there is still TONS of power left in it.
What's great about it: LOTS of power yet sounds very clear. Takes up very little space
What's not so great: Took me to long to find it !!!
