Craziest system on stock ALT!!

[audioholic 5,000+ posts]

You could hook up a million watt system to a stock alt and have it survive, if you know what you're doing. But if you are pretty much clueless and think your 12 volt charging system is run by magic and voodoo, then that's not gonna happen.

The key to running a large system on a stock alt? Two ways... burp it, relying on your batts to maintain as much charge as possible through the relatively large demand but short duration. Second, setting your adjustments artificially low and/or never turning the volume knob up so you never actually output that large wattage number. Either of these tactics, followed up by bragging to your friends what your system's advertised wattage is, while running on your stock alt, is sure to impress people into believing the whole voodoo thing.

But the truth is, you cannot get something from nothing. Every watt of energy your amps put out to your speakers must/will be generated by the alternator.

i run 3k daily on a stock alt with a kinetik 2400 in a hyundia tiburon.....voltage drops to about 12.6 after beatin for 20 minutes or so

I had a stock 110a alt, kicker zx2500.1, zx650.4, zx350.4, stock battery, and gel bat in the rear and I had no problems. I have a friend that's running a 7kd, jl 350.4, yellow top up front, 3 or 4 bats in rear, w/ 2 batcaps, and stock alt. doing about 149 or so on a termlab legal. We hadn't clamped anything so who knows how much power we were actually getting.

Seandub has an 5000D on a stock Izusu Rodeo.

He has some test results too.

i ran 2200 watts from an IA20.1 in my civic with an 60 amp alt. stock battery. alt. died 2 years after i took system out.

people say they ran alot of power on stock alts say like above 20.1 on stock battery upfront and stock alt, but did u trully turn the gain up to put out all the power the amp can do and did u run at full tilt and if so i am sure u had low voltage and that amp is a beast then

I put a Hk4000d in my old Mustang and turned it up on the stock 105a alt and 2 batteries just to test the amp. Voltage dropped from 14-11 and the amp would shut off lol. It was only in there 5 mins though, I was just testing it.

yea most amps will just shut off if they dont have the correct voltage right

kicker is one i am asking about

id run it at full tilt all the time. gain was never really even touched. maybe 1/4 of the way. i was happy with 154db off a termlab in a trunk car, with two 12's. of course my voltage dropped. but it never came to the point to where it shut off.

if my voltage gets too low the kicker will shut off before frying correct

i had 1800rms on stock (only big 3 and 1 primary redtop) without any problems, just the typical headlight dimming, nothing major.

well i'm running around 2000W.. big 3 and yellow top. No light dimming issue. sometimes voltage drops reall bad about 12V. up or down.

No light dimming at all unless i demo really loud. At moderate listening level volume around 13/30 is fine... if i crank to 20 it'll b my max listening level and HU lights will dim at 18/30 volume. My headlights is fine...

I ran about 3k worth of watts on stock alt w/ Stinger SP1000

Idle was 14.1 and full tilt was 12.7

was the full tilt at idle or crusing over 1k rpm

i'm running a bxi1606d at 1ohm , an mbquart p4100 (600watt rms worth to component) and a cheap power acoustic 100x2 to my rear speaker... so that's around 2400 watt rms worth of stock on a 75amp alternator (accent 99).

My big three isn't finished ( the alternator is a ***** to gain acces) but my batt neg is done. No deep cycle battery, only a cheap 750 cranking ampere battery from walmart.

With the car on, the voltage drop from 13,8 to 12,4 at max. This is on iddle i can't mesure it while on the road.

No problem so far, but i'm pretty sure the battery / alt will be to change real soon. No real dimming on the highway exept if i run the system at full tilt , witch is too hard on the hearing
