Retain OEM Amplifier - Retain OEM Subwoofer - Bypass OEM Amplifier - Toyota Wiring Harness
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.
When replacing your factory radio with an aftermarket radio you will want to most likely retain your OEM subwoofer for your bass notes. Subwoofer retention harnesses make this very easy with a simple plug and play connector so you don't have to splice signal wires to aftermarket connectors that your new aftermarket radio can use to send the audio signals to the factory subwoofer.
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.
