04 Mazda 3 cant handle an HO alt?!

[RT32 0]

Hello, I heard that Mazda 3s computer systems cannot handle new HO alt's, so that being said I wanted to just fabricate a new bracket for a secondary alt instead, but there is no possible room to put another alt. so I was thinking of just getting more batteries instead, is that a good choice? or should I investigate and try to get a new alt anyway. Right now I'm currently running 1800 rms with stock alt big 3 all 1/0 100% OFC and XS power XP750 and getting pretty bad voltage drop, I'm going as low as the upper 11s . and my amp gets a little hot (i think that's why). I plan to upgrade to 3500 rms, so that's why i want a new alt. HELP! thanks!

As long as the alternator runs at 14.4v, I am not sure why there might be an issue.  But some cars are touchy, I didn't have any issues with my Mazda Protege5 alt wise.  An upgraded starting battery, BIG3, and a secondary battery is always a good practice for upgrading the stereo.  So you look like you are off to a great start.  

Did you upgrade your starting battery?  Do you have room for more XP750's?

I don't have a stock starter battery although it is better, I can't say by how much. Also as far as my plan goes, I don't think I will have room for more xp750s. but at the moment its really tight already. I did just find a 250 amp HO alt for my Mazda, would that be enough along with the xp750, for 3500wrms? and what starter battery would you recommend. also, I do want room for improvement in the future. 

Thanks for the help!!

I can check if we have one for SSA, alt wise.  250amp will help for sure.  2004 Mazda 3 correct?

Ok, let me check.

Ok, sadly, we don't do Mazda alts for SSA Alts.

Agreed.  I used to have a 2004 Protege5 manual.  Loved that little car.

Was a great car for me.  I did a lot of work on it and tracked it a few times.

That sounds like fun, I would love to track my Mazda but I wouldn't want to damage anything by mistake lol. I want to get like, a dirt cheap Miata and track that, or an old Volvo and drift it lol.
