Posted October 18, 201113 yr Hello, I am in the process of deciding what I should do. I used to have a 180A alternator and it went bad. I sent it back to get fixed, and they quoted me $170 to build it back to 180A, or basically to fix it. However, they said that for $100 more, they can rebuild it to 200A. (I took it apart just for fun when I sent it back to them, just for fun, and it looked like it was a completely stock alternator which I thought was weird, but then again, I don't know what, besides rectifier diodes, is used to make an OEM alternator a high output alternator. What I do know is that I must've paid close to $350 for it back in 2006.)Anyways, when my system will consist of, will be: two (2) PPI A300 for my frontstagethree 12" 5000RMS woofsAn Amp that can provide about 2000wRMS @ 14v that's 0.75ohm stable.That's pretty much 2600wRMS...do you think that a 180A alternator and Optima YT w/big3 is enough? I read somewhere the YT are not good batteries for car audio?
