[QUOTE="audiolife, post: 1265280, member: 541383"] alts dont just produce full power when on. i had 2 soundstream 3.0's and a 6.0 in my old firebird no class d all a/b with no caps hooked up on a 120 amp alt at 2000 rpm (was about 90 ish at idle iirc) and never had a dimage problem it ran 2 eqs a x over 3 amps a noisegate with a pair of controlers everything in the car was powered it didnt dim at all, only problem i ever had with it was with key off tuning sessions killed 2 red tops. all 3 amps were also modded for more power oh yea was also a 4th amp used as a line driver a usa 100. now i have a vga 320.4 requires 90 amps of fuse (has an 80 anl) my alt is an 80 amp alt (full power) no cap, 1 battery no dimming at all reguardless what i turn on. for it to be a "strain" all the time there has got to be a reason/problem as it souldnt be a real strain until you try running a test tones through it full bore for more than a few seconds [/QUOTE]
