Can a stock alternator handle this entry-level system?

[mikez0rs 10+ year member]

I currently have a 1995 Oldsmobile Delta 88 with a stock alternator.

My system:

(2) Kicker Comp 12 4-ohm subs wired in parallel = 2 ohm load.

(1) Kenwood KAC-8105D Mono amp that does 500rms at 2 ohms.

Each sub does 50-150rms meaning the max load could be 300rms total on a 500rms amp (no issues with this).

Will a 1995 stock alternator handle this? I couldn't find the amps on the alternator online.

Thanks

depends on the alt ,what car /truck?

1995 Oldsmobile Delta 88. V6. My initial guess is that the alternator is 80+ amps. The max load will be 300rms with both subs at peak performance (but the amp will be putting out 500rms). I'm guessing average load will be 200rms and that number seems safe for a stock alternator.

Problem is the alt amps are very low. That's why the extra battery and or big 3

@mylows10, he should be fine. That is barely any power.

Trust me, it'll be fine. Unless your alternator is even lower than I imagine, I'm assuming it can handle recharging on a 500w pull.

Your stock alt is 120 amps. You're more than fine.

Thanks for all the replies. You guys make it sound like this system is going to be weak =P. I've only heard good things about this amp, and the subs are in a nice ported box. I'm going to give it a shot without doing the Big 3. For what it's worth, I just installed a new Interstate battery, so maybe that will help.

Your stock alt is 120 amps. You're more than fine.

Thanks. I've been looking for this information. Do you just know this or did you find it online?
