Toyota Stereo specs-Anyone?

Even if Toyota did have the specs someplace, they're probably not going to be readily available to the public. But I'm sure the specs are just fine anyway. Factory radios are usually a little short on power output, but most aftermarket radios are so poorly designed that I'd never put one in my car. Plus, you can always add an amp if you want more power. Some car stereo stores carry male wire harnesses that will plug into factory radios, and the harness will have standard wire colors that are listed on the package. See if Metra part # 71-1761 will fit your radio. If it does, great. If not, your radio is probably designed to work with a factory Toyota amplifier.
