Will my alt push it?

[ShadeTreeMechanic]

Install what you have now along with a volt meter. Start saving for an alt. The volt meter will help to keep you from operating beyond the alts capability. This will be hard on the rectifier and the volt meter will let you know when one of the diodes fries. I would bet you could go a whole year before this happens. Hopefully you can get a big alt before it leaves you stranded.

You sure about that? My old system saw under 10v quite a few times and took it like a champ. And lol at thinking you have to spend $600+ for 2 batts, I paid $90 ea for 7 group 34 dekas

gotta love real world testing lol

Um...so....what? Lol

I haven't found a HO alt for my car that's anywhere near being cheap....under $300.

What would I need to run a 1kw? 120A? Lots of stuff here, lots of confusion lol thanks though!

Did you look at US alternators or check any auto electric stores local to you?

I'm lost as to why yall are telling him he needs an alt for a 1500w system, I'd run a decent agn or two and call it a day. But then again I'm not one who freaks the fuck out when voltage drops to 13.0 either.

Because if you see under 13.6v, you are now using everything that alt can put out, and stressing it. Do that for long enough, you will kill it, and possibly create power problems in the cars system

Edit: I say the thing about an alt dying ^^^^. From experience, my alt in my ford escape is a stock alt, don't know how big it is but it's probably 90a, tiny thing. Even with a big 3 upgrade I still dropped to battery power any time I went full tilt. Well I drove full tilt every time I was in the car. The alt got screwed up, now when I crank it, I can very easily drop to 9v. Why did this happen? Because my barely 1k watt amp was too much of a strain on the alt. It handled it for a while, but it wasn't meant to. So OP, if you want to save yourself the money down the road, of having to replace parts that break down, spend a decent amount now on something worthwhile, that should never have to be replaced.

I have had my t1500 and t400 on stock alts in both my f150 and my scion. I haven't had an alt die yet. As much as we like to overkill things here, it's not that crazy to run that amount of power on stock electrical.

Get a couple XS D1200's, Plenty of juice for 1.5k and small enough to put anywhere.

because its a 90a alternator which will be putting out around 60a at idle .. he wont even be near 13v try 9v.. been there done that with a stock 105a alternator.

the amp alone will use up all the alternator. now add what the car needs to run

Let alone the minimal 20-40a a 4 channel could need at full tilt too.

Just for the OP, yes stock alts can run things. Yes people do it. Yes, they have not failed in some situations. But just expect the chance of it dying in a year or two, the possibility is definitely there when trying to use more than what is available.

Whew! Lots of stuff! Thanks guys! I'm saving up for everything, just need to add some extra for an alt.
