just for your information
my standard system will MAX out a 4 gauge oversized wire (equals 2.97 awg)
its only 2 amps, a PDX 100.4 @ 60 amps and a KAC-9104d @ 60amps.. thats 120 amps, and pretty much the max of any 4 gauge (over max for cheaper brands) wire on the market
for your future reference, both amps are Class d and extremely efficient. And i dont think you should be giving advice and suggesting having another battery or CAPS
caps are kinda useless for extended listening, great for about a whole 3 secs (if you have a 6 farad with my system for instance) but otherwise, a big empty space
if nething an upgrade of the alternator to a high output alternator is all you need (which also requires replacing the stock ground wire for the alternator!)
Id have to say that your car would have had to be running 2 gauge or smaller in order to run a 2000 RMS amp and a 400 RMS x4 amp... in fact it should have ran 1/0 or even 2/0!!!!
if you are talking bout systems that are bought from walmart, no they prolly wont need 4 gauge... BUTTT and thats a big but they might
for instance, my gfs system was walmart type stuff... a jensen 400 RMS amp and a pioneer 60x4 RMS amp... this put me just over the 60 amp max of 8 gauge wire, so in this case 4 gauge was just perfect.... but only to a distribution block where it broke down to 2 8 gauge wires ;-P

no, the system was designed by me and a spon in Ral who held the loudest vechicle in the world status for 3 years, Creative Acustics, Stroker Van. I was running 1-bd1000 Rockford Fostage amp with the dual VC speakers set up as a 1 ohm load), a Rockford fostage 400a4, all these went into a fuse box mounted on the amp wall (front part of the sub enclosure, but not part of the actual sub box), also into the sub box was a 600watt dc/ac converter to run playstation (also ran my dj euiptment off of it), off this cam a 2gauge wire to the 2nd batt (optima yellow top) concealed in the base of the wall. The 2nd batt got power from a 2gauge wire running from the first battery/altenator with a 40amp circuit breaker on it (originally used a 40 amp fuse, but the fuse kept breaking (like cracking in half) due to vibrations. stock alt. and normal batt under the hood. My mids/highs were MB Quarz componant speakers (before they got bought out) and my head unit was a kenwood Video touchscreen (before they started putting dvd players in them) will TV reciever. this was in a 97 dodge dakota extended cab, with the full backseat removed and replaced with the subs and amp, the 2 18" dual VC rockford subs pointed straight up with a comp. tuned box, pushing 145.9bd of bass to the front windshield, i could have gotten more db by adding a 2nd bd1000 to the system with a 2 ohm load on each b/c it was designed to do this if we wanted without having to re-do too much of the set up (if you saw it you would know what im talking about), but i didnt feel like re-enforcing my windows, also if i would have taken the head liner out i would have gotten a few more db's but at the same time, i wanted it to look somewhat good inside. this was back in 1999 or so ( give or take a year or so)
As for what I know about running power things in vehicles, I worked for a Communication shop for a long while, installing police lighting and 2way radios (with some of the larger ones pulling ALOT more power then any audio system you will put in a civic, think about a fire dept moble command truck). We didnt even keep 0gauge wire in the shop b/c it was never really needed, Exp when you can run 2 smaller power wires for much cheeper then running 0gauge. But then again, what Do I know, i just studies lighting and sound system design for theatres in college (wich those amps draw even more power than any veichle can handle, i know, diff type of thing, but i still have to design the power source for these things as well when i design a system). Plus I have been install car audio since 1995, and police lighting and 2 way radios since 2000. Plus, did i say I'm a FCC licends radio operator, witch means i had to take many test on electrical systems (FCC id KF4ZZE)
