Grounding issues could cause such a problem (if your headlights don't dim but the amp's voltage drops 'n stuff, it could indicate a wiring problem on the amp side, power or ground)
Where are you getting those voltage measurements BTW?

Some things you should test are your battery and alternator. Is your battery in good shape? Has it been asbused from cycling? Is it sulfated? Is your alternator putting out enough amperage/voltage to charge your battery adequately?

The only concern I have is, the stock electrical system doesn't like to idle too low. So if you have a manual, make sure to raise the idle a bit to about 750rpm, as opposed to the 600rpm. If you have an auto, I wouldn't worry about it at all.
