no the wet cell will kill the agm, happened to me shits no fun. Just wait a week dude. OR make a small buss bar where ever your 0ga is running and hook your 4 channel up to that.
look into the deka intimidator batts sealed agm battery for about 175 shipped, specs are pretty close to the yellow top but im not 110% i would have to compare them again
im getting a jeep grand cherokee as well pretty soon hopefully, as long as nothing happens to my trade in value. My plan i 2 15s at first then a rear seat delete for a wall or just a really nice no no wall box.
you ever think of looking an hour or two away? Im sure theres got to be some shop around you within an hour or two drive. Would be worth the drive and be cheaper than shipping door panels.
