I was wondering if anyone had knows the input voltage limit for the JBL amp (2004 ITech model). I have read the the factory head unit sends 2v, but I am wanting to connect an aftermarket head unit via the RCA outs with are 5volts. Just wondering if anyone knows if 5 volts is too much? Thanks
I would think 5 would be way too hot a level, you could always pad the output to achieve the desired voltage with some resistors.
Prius JBL amp has DIFFERENTIAL inputs, don't ever try to screw with RCA et al. Prius JBL Audio system response, specs, and photos - RTFM first.
