but is there room to run a duel set up under hood i did in my old jeep but not sure if there is room in my 89 runner
you can always move them. A lot of people move their batteries to under their bed, when they run duals. I could probably fit another battery under the hood in my '86 4runner with a 22re, but it'd be a tight squeeze. It'd be near impossible in my '91 with the 3.0
