I've had a little work done here on things I'm either too lazy to do, don't have time for, or don't have tools for.
They put in my headunit and my alarm.
Most of the stuff in store is fairly expensive (It is a local store, to be expected)
Labor is actually reasonable, with mount and cutting (took cutting/trimming of dash to get double din to fit my car) I believe install was around 100-120?
Alarm parts and labor was around 220 I believe (maybe 200 or 240), brought car to them and was done same day
Install guys are real helpful and willing to answer questions, however they dont seem to follow internet brand and trends like Sundown, AQ, etc.
Overall if you need some install work done they'll do a good job for a decent price usually, also do fast work typically like I said.
They will also test equipment for fairly cheap, been a couple times i've bought amps online and had em test it for me for around 20 bux
