hey guys im new to the forum. ive been looking around for the best answers on what exactly i absolutely need to power the system i want to put in my car. the car is a 99 grand prix supercharged. im planning on installing jvc arsenal series HU, JBL power series 5 1/4 fronts 55w rms 165 peak, JBL power series 6x9 rears 110w rms 330w peak, JBL pb1220 12" ported sub enclosure 400w rms 1600w peak

to power this,i am getting a JBL GTO1004 amp for the speakers 600watts, and a JBL GTO7001, 700watt mono sub amp

now the confusing part begins... i have been told that if i run a 4gauge power wire back to the trunk then use a power block and run 2 short 8 guages to the amps with 8 guage grounds on them that i should be fine with stock alt and wiring. however, ive also been told to do the big 3 upgrade or get a cap (both of which seem to not be needed in my case) but im still not sure and cannot get a straight forward answer

so my question is will running those 2 amps off of stock alternator and a newew battery in the car with the proper 4 and 8g wiring be fine? and, whatd you guys think of that setup? all for less than $900 new!

also all speakers and sub are 2 ohm... thanks in advance for the help!!
