Bypass OEM Amplifier - Speaker Replacement - Retain OEM Amplifier - Toyota Wiring Harness

Bypass OEM Amplifier - Speaker Replacement - Retain OEM Amplifier - Toyota Wiring Harness
Bypassing the factory amplifier is a more difficult undertaking but provides the best sound quality gain. When bypassing, it takes a more work because you have to run the bypass harness to the factory amplifier, which is often located in some other part of the car. Bypassing the factory amplifier will require an aftermarket amplifier or using the aftermarket radio's internal amplifier.
Easily replace your factory speakers without cutting a single factory wire. Speaker replacement harnesses make this very easy with a simple plug and play connector so you don't have to splice the factory speaker cables.
Retaining the factory amplifier is the easiest option when replacing a factory radio. In some vehicles retaining the factory amplifier is the only option. But your new stereo's sound is limited to what the factory amplifier's out capabilities are.
