Good luck. Most of the shops here hire children with little knowledge. The guy who owns Sound FX up on Grant and Oracle does know what he’s doing, but you will probably get a stoned installer who smokes blunts in your car while doing the work. Audio Express is hit or miss, I’d avoid there. The specialists will have nice overpriced equipment, but it’s sold to you by a 20 year old who only knows what he read on the computer screen in front of him. The install will be decent there, just really overpriced. I’d probably go with Sound FX if I were to need an install on something. The owner their has competed and knows the audio game pretty well.
