Ok hey guys so went to clean my Windows today in my truck went to start it and nothing. Then I went to the driver side I let is crank for like 10 secs and it turned over. While it was cranking the voltage was slowly climbing now it did start. I took it for a ride everything seemed fine. Got home and put a new cps in it. Been starting fine since then so I'm like wtf lol I has 2 brand new batterys. Also for the last week or so at idle after work it kinda sound like its caming like every 2 secs its sounds like someone is behind me with subs yall know how that's sound I'm thinking its from my stacks vibrateing Mayb some one can help thanks.
