"Does anyone in Columbus have any suggestions for a car audio installer that's not Columbus Car Audio? The last time I dealt with them, I gave them very specific instructions, they charged me $130 to hardwire my V1, then did the exact opposite of what I told them I wanted done, and when I brought it to their attention, they refused to fix it without charging me even more. I need to have their work fixed, my dash cam hardwired, and my new AL Priority system installed, so it's a good bit of work I'm looking for."
