vehicle fit guide

The JBL GTX500 is the ideal upgrade for those car audio enthusiasts who want exceptional bass without breaking the bank. And don’t let its size fool you. While the GTX500 may be compact, with a max power output of 750 watts you can drive your subs as you see fit. While its true JBL sound sets it apart from other subwoofer amps, it’s ease-of-use and installation, configuration and calibration makes it truly stand out—it connects to OEM or aftermarket systems without complicated adapters or setup routines.
