We offer high quality expert service with flexible nationwide coverage backed with a lifetime labor warranty. Our Professional Installer will install an aftermarket 2-channel or mono amplifier including wiring it to an existing car stereo system. The installer will mount the unit while wiring power, ground, trigger, speakers and the input from the existing car stereo. An amplifier installation kit needed for the installation is not included and can be purchased directly from InstallerNet at the time of scheduling or the customer can supply the part. Some vehicles may require additional labor and/or parts due to the complexity of their wiring and accessing replacement products, for example - if a bypass harness or hi—low signal adapter is needed, or extra labor for speaker wire accessibility.  Please note - this item is non-returnable after 90-days or if the installation was completed.
