Hi,

I've read in the 'car stereo cookbook' that the solution to my noise problem is... "capacitor to ground at the alternator output"

However, I don't really know what the heck it's saying... I have a bit of noise from the stereo that you can hear and it changes slightly with the engine speed. I guess I'm lucky that I don't have more but I would really like to fix the noise.

Thanks for the help - David

Hi,

It's in an 05' camry.

Bose amp, bose speakers (taken from an 03' chevy silverado). The amp has a simple power, ground and a turn on/off wire.

Speakers are connected according to a silverado wiring diagram.

Thanks,

David

Bose factory systems ( especially the Nissan ones ) are extremely sensitive to input level. It usually falls somewhere between pre amp and speaker level. Your camry's output is likely much higher then what the Bose amp needs. Get a differential converter, two if you want to fade. My favorite is the PIE PDC-LOCv2 but other companies like peripheral, soundgate and blitz make them too.
