Ok, so i'm thinking about getting an amplifier to power two 12" subs. The amp i'm looking at puts out 750 watts rms, and at that power, it will draw roughly 108 amperes. The 2002 Tahoe i'm putting it in has an alternator that only puts out about 130 amperes, and im wondering if this setup will be too much of a draw on the electrical system. Also, it's sort of a stupid question, but I was wondering, do amplifiers (even when at low-mid listening levels), put out their rated rms, or is wattage output proportional to the speaker volume. ex.(woulda 750watt rms amp put out say 200 watts at a low volume and thus draw less amperes)?

    Hey, your question was moved to the CAR AUDIO section.....check it out, it's a blast.
    CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.
