Right now I have a 130 amp alternator, big 3 in 4gauge, and a everstart battery (no specs) powering a PA a3000db and mtx ta7402. Im looking to replace the battery under the hood with a yellow top or leave what I have now and add a Stinger SPV35 in the back of the truck. Any suggestions as to which one I should do? I know the alternator isnt putting enough power but I dont have the money right now to get a higher output one. Just jumping from 95 amps to 130 was about $140.
