had an install of my own equipment. quoted me 350-400. charged 400.. When they called n said it was finished i showed up to find my speaker box wasnt secured and wires hanging out, one of the 2 subs not even hooked up. opened door to find drilled bass knob into my woodgrain console, door tweets exposed on door n no cover put back on withg wires exposed, trim around stereo not on. No explanation how to use top of line head unit. new loud noise when rolling down window. Have two batteries n they say i dont need a fuse or breaker within 10 inches(standard) of battery. After taking car back 3 times, they gave me attitude and said having a fuse or breaker next to each battery is like having sex with 2 condoms on and not neccesary..I have $5000 into system and wanted all the precautions i could take..I consulted 4 other installers in town to confirm the need for aditional fuse and they all agreed.... Now window doesnt roll down properly, trim around stereo falls off, and still have hole in woodgrain console.. Definatelly would not go back, nor recommend
