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!

Omg just stop complaining about the ft1 tweeter, just try to help people out, or not. Maybe give productive criticism a try.

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.

oh yeah, they are a blast to drive!

oh man, they're leaving out us Mazda guys!

Any sundown audio zv4 or zv5 for sale? I'm looking for a 15" dual 2-ohm sub, thanks!

That's ok, thanks for the help!

I have the same Question!

yes, that's correct! 2004 Mazda 3 Hatchback 2.3L W/O turbo

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!!
