Car Audio? How much does Big 3 Upgrade cost?

the BIG 3 UPGRADE is a new 200 amp alternator and have to upgrade the wiring for the power and the ground to chassie and you need to install 1/0 gauge wiring to run to a second smaller battery some were next to the amplifiers then i would attach a distribution block coming off the pos post on the second battery so you have 2 power lines on the pos post one from the first battery and the second with the distribution block attached to is then downsize the wiring going to the amplifiers to what they call for.check with any auto parts dealer for the high output alternator,could be at least 2 hundred,second battery about 60 dollars distribution block about 20 dollars and any electrical shop sells 1/0 gauge wire by the ft and 20 to 30 ft should be plenty unless you own a bus.that's about 30 dollars.so i think it will cost you about 3 hundred for parts and whatever the installer charges you to install the alternator,about 100 tops for the labor so that's about 4 hundred total.then you will be producing some big power for your sound system.
