The upgrades from Absolute Audio can give a vehicle more function or more flash. Or, in the case of LED headlights with black housing and halo accents, it can give them both.

The auto techs offer all manner of upgrades, but stereo equipment is their specialty. Clients can build their dream sound system—even a waterproof one, for boat owners—choosing from regular or touchscreen displays from top brands such as Pioneer and Alpine, and commissioning custom builds for speakers and subwoofers. Car owners can even match that club-quality sound with flashy exterior detailing, such as window tinting, rims, and lift kits.

Those interested in more practical installations might consider remote car starters with optional alarms, or weather-resistant features such as salt-proof undercoating and rust-proofing for door jambs. Absolute Audio is even a Diamond Level retailer of WeatherTech custom floor liners, which are ideal for four-season climates or those traveling with swamp monsters.
