Hi guys, went back to DC sound about 4 months ago this time to get my stock speakers changed out on my 2015 Silverado to DD Audio and also a DD audio 12" shallow mount subwoofer .They also found a subwoofer box for me online and put it under the rear seats with no modification to the truck. Drove it around a few days but didn't like the sound of the subwoofer for the money I spent. I called Carlos and he was more then happy to get it right. This time around they made me a custom subwoofer box and changed out my single 5 channel amp to two amps for more power to the subwoofer. I was very pleased this time around for having 1 12" sub. Sounds good and has good quality. My truck still looks all stock they did a great job, you get what you pay for. Thanks to the guys at DC sound yet once again, they really take the time out and getting it they way you want it. So if your in need of some good quality sounds with a great warranty you should stop by and at least check them out.
