I took my 2008 Enclave in for a total replacement of my in dash Nav unit. I was extremely satisfied with the level of experience, fast work, very high quality workmanship ( not a carpet fiber out of place) and the very friendly customer services. Lastly, the price I was quoted was the price I paid - no attempt to upchage me for other stuff I did not need or to piecemeal me will additional cost. Very Very Satisfied! Dr. C. Brandon

These guys were great. They definitely know what they are talking about and are extremely helpful.

I purchased two L3 kicker subs in enclosers. The guy went and plugged in the sub in his car real quick just so i could hear if i liked them. Amazing service and amazing prices.

The staff at Mas did a great job on our truck alarm. We have had it over a year. Just last week the truck wouldn't run. The owner of Mas sent one of his tect's over to my house, since I said it was the alarm. They checked it out and it wasn't the alarm it was the starter relay on the truck. They were quick to help us out. I would just like to say thanks for all your help
