I would say definitly, Your only going to get the best performance from your equipment when supply adaquete power. I just ordered a 160 amp from Ohio Generator. It was very pricy but They have been around since I started installing in the 90's and have a great rep.

cause i was thinking of getting a US Amps USA-300X..old school...900x1@ 4 ohms...and its 135A fuse rating...but would I be okay with just a yellow top..cause I plan on getting one really soon...as for the alternator....ohio gen is good really good...But who would install the alternator?? Cause its not like its a stock replacement that the dealership is used to...I am sure my local shop can do it...but it dont hurt nothing to put on a bigger...say 200A alternator..just adds more power...i guess i will check out ohio gen web page..if i can find it..thanks

Actually the alternator they have for your car and mine is a stock replacement but with different internals. I just got the call that mine is ready but they are cash only, they will not except debit or check so I have to go down to Ohio to get it.//content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif
