Our customer brought in his 2015 Ford F150 for an upgrade in sound. We installed 2 JL Audio, CS110TG-TW3 10 inch subwoofers under his rear seats powered by the JBL GTO-501EZ 500 watt amplifier. We coupled this with Infinity reference speakers in all four doors, powered by the JBL GTO-504EZ 4 channel amplifier. It gave this truck amazing, crystal clear sound. This Ford F150 subwoofer system was recommended and installed by the tech crew at Audio Express 7200 W. Chandler Blvd. #10, Chandler, AZ 85226 (480) 961-0962 your car audio installation experts.
