78 jeep cj alternator

ive been shopping around for a HO alternator for my 78 jeep cj and the prices are well out of my range($375 on up for 180 amp at idle) i can buy a new stock alternator for about $50 (80 amps at idle) so my question-being i have plenty of room under the hood for mounting brackets ect...what about adding a second alternator???if it is possible how would i wire them together? all wires in parallel? my wiring is all new heavy gauge aftermarket the original altenator is working fine but i have too much draw with my 2 amps (i have ensured that i have an excellent ground) and i will be adding more lighting accesories soon (lights dim when the bass is "hitting" hard) and i dont want to go with a capacitor. i'm fairly mechanically inclined so correct mounting of a second alt. would be no problem.
