I have a Lightning Audio 4 channel amp that is bridgeable but was told it can only be bridged if all 4 inputs are used. My stereo is a 4 speaker, 2 channel system and I had planned on bridging it. Since the stereo only has a right and left channel to input into the amp, can the output be bridged? Does anyone know about this?

You can always us a RCA-Y adapter to split your two low level signals to each amp channel.

One thing I forgot to mention...this is on a Goldwing motorcycle factory radio and until I can figure out how to get a low level, high impedance output from it, I am forced to use the high level, low impedance speaker outputs. I don't really understand why I can't just wire the speaker outs to all four inputs on the amp but a tech at LA said there is no way to bridge the outputs with this setup. Seems like there should be a way to double the outputs to drive the four amp inputs without changing the impedance or whatever the problem is. Thanks
