ACE Auto Sound, Paramount

Cars tend to leave ACE Auto Sound sounding better and looking sleeker than when they arrived. This is thanks to an inventory of electronics by top brands such as Sony and JVC, and technicians with the skills necessary to install said electronics. ACE's techs deftly equip cars with stereos, amps, and subwoofers, not to mention navigation systems and remote starters. And to ensure that cars look as good as they run, they can spruce them up with LED lights and window tints.
