before i go orderina bunch of shit heres what i had planned the set up to be

2 FI Q18's, running off of 2 memphis pr 1000.1 amps. the amps are flexible on what i should get thatswhy i posted this because i relly cannot decide what to get amp wise, i thought about that kicker zx2500 amp and have it powering both of them but i have a friend that works at x-treme audio local shop around here and he said the 2 memphis amps would probly work best. i just need some others input onn it !!!! pleasee, also this would be my complete setup

2 FI Q 18's

2 memphis pr 1000.1 1 channel

then another memphis 4 channel amp probably somewhere close to a 250x4 watt powering the door speakers.

then a kenwood head unit

i have been told all this cannot be ran off the stock alternator with the exception of a new optima yellow battery, but still im just not sure if all that could run off the stock alternator.....(wasnt planning on spending another grand on a altanator) or any more money on an altanator...... and im trying to keep the price of the amps or amp 800 or below,,,, all inputs would be nicee!!!

well why dont you buy a used zx2500 and still have enough money left to get your alt?

how many amps is your stock alty?

i have a 130amp alternator, kinetik800 battery, kinetik2400 battery, and with 2000RMS @ 0.5ohms, i had slight dimming while driving and bad dimming at idle (at full volume), voltage dropped to right around 12 while driving, and im sure it would drop far below 12 if at idle.

i think a stock electrical could hold up to about 1500rms after that voltage drop is gunna be realy bad, then ur ish is gunna start getn hot.

get a kinetic for the back of the car,

and get 0 gauge ,

its better to invest in the elctrical before u even start getn ur large amps and subs,
