I hope you understand you'll have to make big improvements to your power supply, bigger alternator (try marky.b for an Ohio item), split charge etc. You're going to be pulling huge amounts of current there.
you need to try www.utopiaaudio.co.uk for anything on ohio alternators, I have one as I am a db drag competitor and run my system at 16v (charging between 18-20v), you best option will be to uprate the battery, try finding a bigger alt that will have the same mounting from something like a diesel from the same model or get the alternator rewound. Also remember to upgrade the cables from chassis to battery, battery and alternator and if the alt to chassis (if it's earthed) with 4 gauge as a minimum.
