I'm Stuck

I think you can't need a HO alt for 1300 watts rms !

Upgrade your power and grounds to 1/0. Get a voltmeter and watch it.

Then, you will know if you need something else.

You're listening to music, you will not be at full volume every time. Your amps won't be at their max very often.

So, instal and test !

I am on my stock alt (don't even know kind) with a 1500.1 and a 50.4 amplifiers. No dimming, and 0,1 v of drop !

I still have the stock battery.

The AC makes my voltage drop seriously, but not the music.

Good luck

At idle? or at driving RPM's?

I had 1500W in my 00 Sunfire GT (90A alt) and the lights didn't dim.

Was that 1500 watts RMS or peak? Idle or driving? What gauge wire did you use to the trunk? Big Three?

No dimming and 0.1 v dropping with engine on. No matter the rpm.

1500 - 1800 rms ON MUSIC. Music is dynamic.

I have 0 ga for power and grounds. Big3 is not finished yet(Ineed + from alt to batt).

It all depends of your car, your alt, engine,...my car has a Diesel engine, so it may have a stronger alt than others.

I own a 2003 sunfire which currently has a 105amp alternator.

That is what my pos Silverado had and it had NO problems with more power than you are asking. I ran JL power hog amplifiers as well. 1000/1 and 450/4. Correctly wired and voltage drops were far from an issue.

And definitely remove the cap, it is hurting not helping.

Sounds good! I'm looking at new wiring right now. School is done in three days, than let the fun begin.
