I wouldn't mind doing a slight mod of an alternator, but without a grinder, it looks like I can't use the Maxima alternator. I'm going to look for a direct replacement and hope I find one that had high amps. If I can only score a 60 amp, then I'll just keep the sub turned down. Thank you all for the helpful tips

An XT6 alternator? Is that a type of alternator, or is that a different Subaru? What year XT6 do I look for to find that alternator?

Im sure the amp doesn't work if the volts are higher than 14v. Shoot, I've never replaced an alternator before. Hope it's not too difficult.

I installed my sub and amp (500 watt RMS) into this 91 Loyale that I just inherited from my Dad. The sub and amp was previously in an 02 Buick Regal, and worked perfect. When the Loyale hits higher RPM (about 2500), the voltage gauge goes up, near 16 or 17 volts, and the amp turns off. Once the RPMs go back down after I shift, the amp turns back on. Can an alternator provide too much voltage? I thought the voltage was regulated but maybe it's not. The lights don't flicker or get dim when the sub hits, so there's plenty of amps. Is there maybe a way to mod the alternator in some way to make it put out a constant voltage?
