I have to do this post to inform anyone needing professional audio installation...... This isn't the place. DO YOUR DUE DILIGENCE!!! I had wires exposed, a radio and speakers mproperly installed and my truck had screws missing where they disassembled my truck parts. After the initial installation I was so out done at the subpar work, I expressed my thoughts to them about the work, dome tweeters installed in the wrong area of the truck(partition between the driver and passenger windows) the treble was directly in your ears you couldn't have a conversation. Also after the install my guages in my Hummer stop working for seconds at a time often and the road hum do to improper grounding and/or filtering was horrible. I thought who in the hell would deliver a $1200.00 install (not including parts) to the customer in that shape. After expressing my thoughts they begged for the opportunity to correct the install, I reluctantly agreed. I was apprehensive for fear of further damage to my truck. After the 2nd install the road hum was solved and the dome tweeter was relocatied directly above the factory dome tweeter, go figure huh!! This is totally my fault for not doing my due diligence, being excited to get the new system installed. I took the truck to a major chain in New Orleans!!! $685.00 later she purrs like a kitten. When you view the installers at TOS in person ask yourself "are these the people I would put my trust in to do a professional job"? GUAGE PROBLEM SOLVED AS WELL. GOOD LUCK, LESSON LEARNED
