Went to another shop here in bozeman for wiring. Afterwards something just wasn't right. So I took my car back and after messing around with it for atleast 20 minutes, the guy told me that my amp was shot and wasn't getting power to one side. After trying to sell me another amp for $200 I immediately drove out to Sound Pro. Tim came out, messed with the amp for maybe a minute tops and showed me one switch that pretty much fixed everything. Then further explained to me what kind of amp I had. And upon installing a new stereo a couple days later, made it sound 3 times better than what I had expected! When entering the shop I felt like I was dealing with professionals, and I was NOT disappointed or let down.
