try the new trinity IP 5000. It has better numbers than the trackpowers (i own both). Judging by your name you are driving cyclone. The cyclone is one of only a few cars whose upper deck is high enough for the battery to slide under, unlike the RDX you have to have the battery hanging off held in with aftermarket thingy. This is one advantage of the cyclone, u can use bigger batterys and keep the weight closer to the center of the chassis
