I have a 2003 Maxima SE with the BOSE sound system. I plan to put in a new head unit, amp, and sub. Below is a list of things that i plan on buying to add into with installing:

Pioneer DEH-X6500BT Head Unit
PAC ROEM-NIS2 Integration for the bose speakers
Antenna Adapter
Dash Kit
12" Kicker Solo Baric L3
12 Gauge speaker wire
750 watt Kicker Amp
4 Gauge for the amp

I was wondering if i was going in the right direction for installing the new head unit, kicker amp, and kicker sub while leaving the bose speakers in and bose amp?
