Very nice, clean power and I really like the remote control! We installed this into our 2003 trailblazer which will be used by our soon-to-be 16 year old son who will be the primary user of the vehicle. We wired this up directly to the battery, using the supplied fuse. My son did a nice job of wiring under the molding all the way to back of the vehicle. This sits right next to the subwoofer which was handy for hooking it up. The remote control that came with it is also wonderful and allows me to turn the gain down from the window-rumbling volume to which he listens to it, to the more comfortable levels that I listen. This also allows me to balance it with the 6 factory speakers that came with the vehicle. Very, very nice.
