I was testing voltage drops on Two fully charged batts. the Stinger deepcell against a kinetik battery...

If the car was off, what was the point of showing the volt meter? Of course it going to fall off.

damn, that sucks.

Cap won't help with 300+ amp draw man... I have a 200amp alt... car was off...

im a fan of fosgate audio and they look pretty good. nice excurzion. get a cap to get better results because ur falling into the 10 volt range and it should be 12 volts or higher. just a sug.
