Bakerman Posted December 9, 2010 Report Share Posted December 9, 2010 Trying to run 4 alpine type r12's with two alpine m850 amps. I have two optima red tops under the hood, with a stock alternator. Should I beef this up any more? More batteries when i go to the 4 subs and two amps, or will the two redtops be enough. Also the same with the stock alternator? Do I need to upgrade it? If so, what kind should i get? Link to comment Share on other sites More sharing options...

Also the same with the stock alternator? Do I need to upgrade it? If so, what kind should i get? red tops hate fast drain... and have slow recharge... but since it what you have ied try to get atleast a another red top.. because they dont link well with other battery brands. make sure you have done the big 3 upgrade.and if you have the monies get a h.o alt. he wouldnt be the first to say they did a 167 with a system like that (one that clearly DOESNT), but i have to say, he didnt beat me anywhere, ive never competed against the guy. If he thinks his does a 167, mine would probably put him in a coma. :hairtrick: Link to comment Share on other sites More sharing options...

ugpbmx Posted December 9, 2010 Report Share Posted December 9, 2010 before you do anything, you need to tell us what your voltage drop is at full tilt. go ahead and do the big 3, it needs to be done anyway. Red tops discharge quickly, and take a while to charge back up. so they are not ideal for car audio. what amperage is your stock alternator? MY TRUCK BUILD - 1976 F-100 Ranger. Fully built 482 big block, 4 DC lvl4 15's in a blowthrough, plenty of custom fabrication. MY HATCH BUILD - 1993 Honda Civic DX Hatchback . Clean daily driver, dropped, subtle customization.
