Battery needed?

[swangandbang 10+ year member]

My intended setup for 2003 Altima:

- Hifonics txi 6406 (4 x 85-Watts RMS @ 4-Ohms)

- SLC 230

- SL 6x9

- Sundown Audio SAZ-1500D ( _________ @ .5-Ohms)

- 2 15" SI Magnums

- Pioneer DEH-7800MP

Since this is my first time install, I was thinking of getting a battery to put in the trunk because there's a spot where it would fit perfectly and it would make my install much easier. The problem is, how will I keep it charged? If the steps needed to hook up my 2nd battery to an alternator are harder than just wiring it some other way, let me know. Do I need a 2nd battery for this setup? If yes, than should I get kinetic or optima yellow top?

wouldnt hurt ... between the kinetik and the optima i would go with a kinetik for 3 reasons. 1. has more reserve 2 . if you happen to nuke it it gets replaced 3. if you run down the 2400 generally it takes a charge without haveing to worry about it doing damage.
