Our Plug-N-Play Amp harnesses are designed to make the installation of one of our 4 or 5-channel DSP amplifiers even easier to install. We make a variety of harnesses for different YEAR/MAKE/MODEL vehicles that are equipped with standard factory radios. (Will not work if the vehicle is equipped with any “Factory Amplified Systems” i.e. SONY, B&O, ALPINE, JBL, etc…). These Plug-N-Play Harnesses give the amplifiers both the Hi-Level input contentions and the Speaker output connections. These harnesses also come with a TOSLYNK cable that can be used when installing one of our amps into a vehicle equipped with one of our Generation 5 or newer T-Style Radios, one of our IQ Radios, or one of our Double Din Radios.
