Im confused, the title says daily, but everyone is talking about burps.
To the OP, you are planning on running 4-4500 watts 'daily' on a stock alt? Your realize that amplifier can draw over 350 amps, by itself right? Consider that when you are only upgrading the big three and dropping in a couple batts. Even with a serious alt, that's gonna be a heck of a draw on your charging system to deal with on any sort of regular basis.
Lastly, I do not understand the idea of buying a mega huge amp, then trying to find speakers to match it. What was it that told you you require 4000 watts plus for your daily system? I mean, if you were someone who had their heart set on a pair of subs that needed that much power, i could understand going from there. But to buy a 4000 watt amp, then ask a bunch of strangers what can handle it....? Seems like backwards logic to me. Not dumping, just wanting to follow the logic, at its getting more and more common.
