[QUOTE="los33, post: 8444157, member: 660834"] Is the stock alt only is 90 amps then during idle it will do near 40-50 amps if your lucky. Just remember 1000 real watts on 14v comes out to be 71 amps. So your alternator having to charge not only for the stock system, but for your radio and amp then you will be left with an over worked alternator. Adding another battery will just add to the load, but will help if you dont listen at full volume 24/7. Since most 99 altimas come with 100 amp alts id say just get your stock alt rebuilt if there is anyone local. If you plan to go big later on then just buy a new h/o alt. If this is just for the drive till you sell your car then add a very large agm like a d3100 and watch your voltage for voltage drop because with such a small alt if you let it dip to low 12's to long who knows how long it will be till your alternator dies.
