Sorry. Been busy lately. I haven't hooked it up yet. It's been too hot in Texas, so it will be a fall project. However I had a simular unit in my old Nissan pickup and it sounded great. Couldn't break the law with it but it had plenty of rich bass for just rockin' and rollin'. I plan to just tap into the speaker wires behing the head unit with those side clip-on wire connectors. The wire harness on the unit is sturdy enough for the amount of wattage this will carry. Also looking into a small amp for the door speakers and a 7" gps/dvd head unit. Found some on lightinthebox.com for under $300.00. Again waiting till fall.
