The guys at L.A. stereo are awesome. Their customer experience is great and they take care of their customers. I got a sub and amp installed in my new car from these guys and they did a great job. Not only do they use materials to keep the install very clean, they also mounted my sub so it doesn't move around and stays put. In addition, they tune the audio to your liking to ensure you get it just right. I highly recommend L.A. Stereo for any of you audio needs.
