dont do it lol, Mitch or someone else will be able to give you some more solid advice but generally car equipment and especially subs will run at a lower ohm, therefore potential to blow it. Are you considering just using this and some other speakers, or what is your plan? Highly recommend just hiring two 12 or 15 inch JBL's from Dj Warehouse or similar, you wont need the sub dude. These speakers will be powered so you wont even need the amp, all hired speakers are already power by internal amps generally.
