No you can't bypass it.
Even volume control passes through the amp.
You can only take high signals from the amp and pass them through an aftermarket amp with high to low converters.
Audison BITONE is the best for the job.

Yes, providing you get a wire harness from Beat Sonic or the Scosche dash kit. I replace my stock radio via the Beat Sonic harness (2007 IS250 without ML) and the sound quality along with the volume improved significantly. In my current setup, I bypass the factory amp.
