It was stock alt and stock batt with xls power batt in the back and two runs towards the back of 0 gauge and big 3... the problem stopped for awhile and I took my system out until I buy my DC power alt but today my car died for a quicker sec while I was driving as in stereo dead and rpms fell evryrhing dead but got back up??? And I drove it home started it again and it started good but went to the store and died completely!!! I took off Tue pos battery terminal off and waited for 5 min. Then it got electrical again and I took it back home??? Any ideas on what's wrong with it (back to step one fuck me)
