I have a kicker 1500 and i plan on using it for either a kicker sc 15 or a cvx 15. My questions are 1. Is a HO alt necessary, i have a 92 saturn sc, and when i had a 900 watt rms amp i had no dimming. 2. I have a kinetic hc600, should i install that as well or is it not necessary. 3 Which of those two subs will work better in a sealed application, they will bothe be givin the recomended amt of cb ft. 4. if i port the cvx instead of seal it, how would it differ, in quality and output. 5 The car is really small so is 4 guage enough for that amp, most likely itll be running at 4 ohms, does it still draw the same amt of amperage if its at 2 or 4.
