Not using the RCA outputs and my vehicle is equipped with a factory AMP, anyway to cutoff the internal amp? Line output converter to GMAH24 does not work. I'm getting a hiss from all my speakers with zero volume selected on the HU. When I turn the line output converter down the hiss vanishes but introduces a new sound that sounds like a CD loading.

2008 Corvette w/o Bose

Pioneer F90BT

Peripheral GMAH24 and GMAHCM

Tried the Peripheral ISEV61 (It fixed the hiss, but introduced the new sound above)

Any help?

Thanks

I have a 2005 alitma se-r and it too has the bose system with the amp. I really hate that hissing noise but I am gussing the best solution is to get another amp to replace u r bose one. This is of course what my installer told me and I am not 100 percent on it but it my work for u even with the new noise problem that you have.
