I need a new alternator. I'm wondering if you know how big I should go (just stay stock or upgrade to 200 or something). I currently have two gauges, a pioneer 7" touchscreen, and a 9" sub with amp. I always keep the sub on the lowest setting - I just have it because I lost all bass when I installed a shaker 500 years ago. I listen to my tom petty at a decent level... Just wondering what size alternator to go with because mine has gone bad.
I thought id post in this section since it's going to be you electronically inclined folks around here.
I appreciate any insight!

 

Lol... not even close to needing a 200 amp alternator. Most of what you listed draws miniscule amounts of power

 

Another stock one will do? I had my stock one rebuilt last summer and it's bad again so I thought I might be using too much or something

 

Such things happen naturally... and with rebuilds. Unless you are pushing tons of power into your speakers (you aren't from what you posted) it sounds like pure chance in your case.

 

I agree, you aren't pushing enough power to worry about a bigger alternator. But... if it costs the same I don't see a reason to not get a bigger one.
