60 Amp Alternater.. Headlights dimming.. What to do?

[Troydb 10+ year member]

I've got a POS 60 amp stock alternator on my truck. Currently, I am running 2 class A/B amps with about 520W RMS total (120W on components & 400W on sub).

With the gains set pretty conservatively, I get very little, if any, headlight dimming. The problem is, I want a little more output which leads to more headlight dimming when I turn the gains up slightly (to where they should be).

I was thinking about doing the BIG 3, but I don't know if that would be all I need to stop the dimming. Another thought was to get an aftermarket high output alternator, but a 200 amp alt is well over $300

I am also considering going with a Class D amp on the subs, but I want to go with a 150x4 on the comps to go active. I could gain some efficiency with the Class D on the sub, but the larger comp amp (class A/B) would draw a good deal of current.

Any suggestions on what I should do to keep from having to spend $340 on an high output alternator?

Try getting a bigger battery and doing the big 3, that may help and save you money from the alty idea...

New to the whole hi output alternators, but I have seen DB Electrical ones on Ebay for under $200... they say they are new with a 1 yr warranty. Not sure if they are decent... I've heard good reviews and they have perfect feedback so they can't be all that bad...
