car is a 96 toyota corolla with a half wall, currently i am running 2 batteries, 1 small interstate under the hood, and a odyssey/stinger 1700 in the trunk, stock 90 amp alt. will probably be adding a couple of optima batteries for finals along with a big 3 upgrade. have tried to burp and/or roll the amp at .25 ohms and it went into protect which doesn't surprise me considering i don't have the electrical to back it up and its quite a low load, so i guess i am stuck leaving it at 1 ohm. this car has been a challenge to make loud compared to my previous cars, i am planning a rebuild of the box in the next few weeks also. its currently only in the mid 140's which is nothing in no wall.
