    Is the big 3 going to be enough?

    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?

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

    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?

    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.
