why is it that you need more power?
a 90 amp alternator, 133 total amps of draw at maximum power. Unless you're constantly running the amps at their full rating (very unlikely), the battery should be well enough to provide the rest of the power

Re: if anything, it would be best to upgrade the alternator first
i can't really find any place to do it. every place just says the best they can do is rewind it. and that as what i've been told, just boosts up a few amps and burns it quicker

Did you check out the Ultranator?
www.ultranator.com. Maybe you could get a 110-amp and have it rebuilt for 150 amps if you wanted.<ul><li><a href="http://www.ultranator.com">http://www.ultranator.com</a</li></ul>

well
audi electrical systems are very good. And I'm assuming that your talking max power with that amp figure. I don't know of a high current amp made by JBL so yours probably isn't one. Heres what I did to my 88' 80 with a 830watt RMS (true power) and 3 JL 12W6's. First clean battery terminals, Upgrade alternator power cable to at least 8guage amp wire(found 40ohm drop on my stock cable), run extra 4guage ground cable from battery to good ground on body, If lights dim when bass hits get a good 1 farad capaciter(lightening cap ~$100) I also had my alternater rebuilt to 110amps (any knowledgable auto electricale shop can do this using a stator coil from another audi). a second battery is unesessary, but will always help. An optima yellow top is a deep cycle battery and is pretty ****ty for starting an Audi (or anything besides a honda) so it should only be used as a stereo battery
