This car audio lover came in looking to give his 2012 Toyota TRD Tundra a sound upgrade. The client liked the options of the factory deck but couldn’t stand the volume or poor sound quality. We started with an AudioControl LC2i line converter mounted under the passenger seat. The converter gave us full-bandwidth 9.5Volt RCA output to the amps. Powering the system is a JBL GTO-5EZ 5 channel amp. This amp was chosen because of its phenomenal sound quality and small mounting footprint. This allowed us to custom mount the amp behind the rear seat. On the receiving end of the amplifier are 6 Infinity Reference series speakers. The front doors now house a pair or Reference 6500cx 6.5” components. The rear doors now house a pair of Reference 6502ix 6.5” speakers. All doors and behind the rear seat have been sound and vibration dampened with black Hushmat Ultra for ultimate high fidelity sound. We also built a custom enclosure under the driver side rear seat for a Kicker CVT 10” sub. Work was done at Quality Auto Sound 11870 N. Washington, Northglenn, CO 80233; phone number 303-255-6006.
