siucsaluki11 Posted June 20, 2012 Report Share Posted June 20, 2012 Well, I've been looking into these, contemplating running 2 batteries, my stock starter under the hood (now 3 years old) and my brand new Kinetik HC1400 in the trunk..... Then i decided fuck it, ill just put the 1400 under the hood, but mitsubishi's engineers decided to make the cable that connects to the positive battery terminal all sorts of retarded, so now I'm back to thinking of just running 2 batteries. One thing that kept coming up when i was looking into dual battery setups is battery isolators. HOW NECESSARY ARE THESE REALLY? Ive seen everything from you must have, to completely useless. To me, the science says yes, it will be needed over time, but how long is that time? Can i get away with just throwing the new battery in my trunk for now? Also, how do some of you trunk guys have your batteries secured in your trunk? woman..cant live with em...cant shoot em...guess were all fucked You might be a Redneck if you use your leftover gutters for a speaker box port...

IdleSilence2580 Posted June 20, 2012 Report Share Posted June 20, 2012 I can only see using one if you will be playing with the vehicle off a lot cause with an isolator it will keep your front and rear batteries isolated while the vehicle is off. That way, if you happen to be playing for a long time with the car off and the rear batts happen to go dead on you, your front battery still has juice to start your ride and you're not stranded. But don't use one if you don't see that as a problem or want all of your batts working together no matter if the car is on or off. This is how some of my buddies explained it to me anyways, hope it helps.

siucsaluki11 Posted June 20, 2012 Author Report Share Posted June 20, 2012 Alright, now how do you guys get your batteries to stay in place in your trunks? I don't have a ton of space, but i have room on the passenger side of the box to fit the battery. I can't really drill into the floor, don't wanna hit my gas tank. So how would you put your battery in your trunks? woman..cant live with em...cant shoot em...guess were all fucked You might be a Redneck if you use your leftover gutters for a speaker box port...

Purplehaze Posted June 20, 2012 Report Share Posted June 20, 2012 They suck for car audio. Period. Tried one, and they are not meant for car audio. They don't give the aux. batt full charge, it's more like a trickle charge. So if you like running your system @12.7 volts or so, then you may like them. Otherwise, forget about it. It's not meant for us.
