Just get a Stinger Alternator (180 amps), big three mandatory upgrade, two D75 Optima yellow tops, and keep the engine rpms at 1500 or more when beating on it. The MOJO's are great for the money. A local guy has two Mojo 15's in a box in the bed of a 2005 Sierra Denali Pickup. It is ported through the bed into the back cab and is running two JL 1000/1's, twin Stinger alternators, and twin Optima Yellow Tops. Also has a 450/4 JL amp for mids/mighs, navigation, train horns, 4 monitors, strobes, and all HIDs in front-explains the electrical system upgrades.
Anyway, that truck hit mid-150's decibels a couple of weeks ago at a local show on the termlab. Sounded real tight (looks nice too on 26's!).
