very low sub output

[cbccadet2002]

alright i just hooked my crappy system back up in my car. i have two rf 10's in a sealed box and a old kinwood kac-729s 600 watt amp. If i hook both subs up whether it is brideged or running two channels then the sub output is very low. but if i just run one sub either bridged or not then i can get power. any idea what the problem is? thanks.

You have the subs wired out of phase from each other. Switch the positive and negative of ONE of the subs. Then you should be able to get output.
