3/0?

Hope you got connectors....

1/0 should be able to handle the 200A of current without problem...

cool,i'll get the 200 then...next question,i've got some 3/0 welding ground cable,will this be ok for my big 3,or do i have to use car audio grade wire?...thanx

I can tell ya that 2150SX at 2 ohms (or 4 bridged) will draw upwards of 90A by itself. lots of power, lots of current draw. If stock was 100A for the alternator, you'll want ample excess current for that audio system beyond the stock rated juice.

When my alt fried, I had to leave my truck at a car wash overnight. Go with what kiki said. Don't forget to upgrade your wires too.

go with the 200A

Depends On What You Plan On Doing If You Plan On Going Bigger Than What You Have Go Bigger Other Wise I Think You Will Be Ok.

so,i'm driving home from work the other night and all of the sudden my voltage meter drops to 12 volts,i turn off the stereo,rev up the engine,it goes back up to 14...as soon as i let off of the gas it goes back down to 12...so i'm looking at a ho alt for my truck...here is what i'm running for amps,nothing extra besides the stereo

orion 2150 sx stero@2ohms per [email protected] volts

monitor 1 mk 2.70=140wrms [email protected] volts

my stock alt was a 100amp...my question is...will a 160 amp alt from motor city reman be big enough,or sjould i go with the 200 amp?
