Is the big 3 going to be enough?

[NJTStang11 10+ year member]

1993 Lexus ES300

2 12" Pioneer Premier 3004's (1000rms per sub)

Power Acoustik a2400db (1800x1@1ohm)

Wired to 1 ohm with each sub getting 900 rms (approx, considering over-rating)

Panasonic 8100 Headunit

Will the big 3 be enough to avoid massive strain on my electrical system? or am I going to be needing a new alternator/battery down the line?

how many amps is your alternator?

a 93' es300 should have an 80 amp alt stock, so if thats true...yeah you will be wanting to upgrade that soon.

ouch, 80 amps on 1800w rms. Definately gonna need an upgrade.

Yes the alternator is 80amps

Amp is over-rated and was benched at around 1250/1300x1 @1ohm

With the big 3, assuming I don't listen full volume all day, do you think my alternator will survive atleast until xmas?

You are going to need a bigger alty...

i got ~1800 watts on my 120 amp alternator with the big 3, still getting dimming at high volumes, but i don't crank it too often. 80 amps is pretty small though.. probably gonna need a new alt like the people said.

It might. Get it installed right - it won't hurt to try. It's not like it will go up in flames instantly.

I ran around 1000w rms with a 75A alt that had about 200k miles on it. Took it around 2 yrs to finally give up.

i suggest you DIY the big-3 then see what results you get after. only downfall i see is your time and couple bucks for the wire/terminals.
