Digital Car Audio at 10955 Alpharetta Highway, Roswell, Georgia.

I made an appointment to bring the car in to remedy electrical engine noise leaking through the stereo. When I showed up on time, they were ready for me. They listened to my description of the problem and immediately went to work. They quickly found the problem which was the RCA connectors from the radio to the power amp and explained what my options were. I decided on the shielded high-end RCA connectors they had in stock, which was their recommendation. The connectors eliminated 98% of the noise. All this was done within 45 minutes. They went the extra mile spending another 10 minutes trying to get rid of the last 2% which they determined was coming from my 5 year old Pioneer radio. Replacing that would do the trick, but the noise was just barely audible and couldn't be heard while music was playing even at low volume anyway. I elected not to replace at this time.
They were professional, courteous, knowledgeable, efficient and their inventory was various and well-stocked. Their prices were very good as well. I highly recommend them and will go there for all my auto accessory wants and needs.
