I was looking at a mechman alt for my car and they only have one 370 amp Elite series billet alternator for CS144 replacement - Mechman Alternators

My question is how do i know what batt to get with that alt just the biggest i can fit?

Also anyone know of another alt place that may be cheaper? lol i wasnt expecting to drop that much on an alt.

The batt in it is a duralast gold but im not sure how old it is and i figured with the bigger alt shouldnt there be more storage space? Truthfully ive never put a bigger alt in my older cars always just put a new batt and delt with the lights dimming all the time so im new to this aspect of the audio game

"This unit is not reccomended for use above 5,800 RPM engine speed, but we also offer a 250 amp version with all the same features that will tolerate high RPM much better than the OEM CS144"

Look into DC power or Singer.

DC has 185 to 370 amp alternators for your car. $300 to $900

If I dropped that much money on an alt, I'd get a good AGM too.

My alt and batteries were about $1,600. Took three months to save up for them

With a 370 you should never even touch the battery. I wouldn't waste the money till you see what it does

I was thinking a 3500rms at 1 ohm amp but then started to really think about the 3 HDS310s will be wired to 1.34 ohm so they wont see 3500 off an amp and then to account in box rise and crap maybe itd be best to run a 4k rms amp at 1 ohm to get close to them seeing anywhere close to 3500rms at 1.34 ohm after rise.

But again first time im thinking about this stuff as well

Omg lol i was hoping to keep this whole build under $1,200 but box subs and amp is gonna be a lil over $1,300 not to mention wires, wraps, terminals and other misc items

Do you think a 370 is over kill? Even though i was told when i first joined here when it comes to electrical you cant over kill it

Lol, this build kind of got out of hand. Hopefully this is the last one I do for a while. I may need another alternator too. Going to see what voltage drop is first though

Lol i think they all happen like that, hell at first i was thinking 2 12s with around 2k rms now its 3 10s in the back seat off 4k rms and upgraded electrical im sure by the time i get the subs something else will change lol

I thought a single SA8v2 on less than 1k with stock electrical was going to be enough. That was less than a year ago. Now look at my sig and avatar, lol
