Watch the bass Posted March 7, 2010 Report Share Posted March 7, 2010 (edited) Hmmm, ok? I said for the big 3, not for the amp runs. You have bought into some marketing hype somewhere along the line. Go back to physics and AC/DC 101 my friend... How many amps are 1130 Watts at 12.5 volt is = ...? And what gauge is right??? 1/0 gauge is right, electrical saftynes is one of the most important thinks in caraudio, in case of carbeque.If he shared the power in the trunk with a fuseblock to 4 gauge is ok for each amp.

toaster Posted March 7, 2010 Report Share Posted March 7, 2010 (edited) How many amps are 1130 Watts at 12.5 volt is = ...? And what gauge is right??? 1/0 gauge is right, electrical saftynes is one of the most important thinks in caraudio, in case of carbeque.If he shared the power in the trunk with a fuseblock to 4 gauge is ok for each amp. What is a "saftynes?" Anyway, again, he already has a 4 gauge big 3 completed. At 120 amps @ 4 feet, he will experience less than .06 tenths of a volt drop. But, his alternator is only 70 amps. Upgrading to 1/0 is not going to make his alternator produce more current. Once the alternator is upgraded, his voltage supply for the 750 watt amp will be higher. Higher voltage = less current. You don't begin really pulling a lot of current in low power situations unless your voltage drops. Less voltage = higher current draw. To answer your question, however: 1135 watts @ 12.5 volts is 90.4 amps of draw. Well withing a 4 gauge run of 3-5 feet. Once the alternator is upgraded, and we are not dropping below, say 13.5 volts? 84 amps of current draw. Don't get me wrong, I am all about overkill in car audio. However, don't jump on a guy and make statements like you did when in reality, what he has is just fine for now.

Watch the bass Posted March 7, 2010 Report Share Posted March 7, 2010 Upgrade first ur electrical, BIIG 3 in O/1 gauge, 2. change ur batt under the hood, take the biggest and best what u can place, (Kinetik, XS, Stinger), maby u can get a nice offer in the "want to sale section" Than can u switch to a second woofer and later u can put a second battery in the trunk together with better or H/O alt. So u can go step by step. Still my stand. Quote "in the abundance of water, the fool is thirsty" Bob Marley Link to comment Share on other sites More sharing options...
imupabove Posted March 7, 2010 Author Report Share Posted March 7, 2010 Four gauge is fine for the big 3 with what you are running.If you ever decide to run 5kw+ and need a few hundred amps of current, upgrade to 1/0. How long of a run is it from your battery to your alternator, 3-5 feet max? batt. to alt is about hmmm for sure no long than 5 feet. so toss out the cap asap? yeah looks like i will have to invest on my electrical. so alt first than the biggest batt. under the hood? i wanted just H/O alt and one big battery setup, and a 2k-3k watt system. but you never know, you know how it is "we just want more" lol. but yeah around 2k-3k watts is what im aiming for in the future. i seen a guy on youtube, he's running 2500k just with a hc1800 and a 260 amp Ohio Ben alt. thanks people for all the replies. i appreciate it for your time.

imupabove Posted March 7, 2010 Author Report Share Posted March 7, 2010 Still my stand. if i were to get a H/O alt and do the big 3 in 0 ga. what kind of differences will i see? please check out this alt. cheapest one i can find that is a known brand out there: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220489683226&ssPageName=STRK:MEWAX:IT Quote iDA-X200/Clarion EQS746 RF T500-1bd (2) 12" RF HX's Kicker 350.4 Alpine & Polk Speakers Stock electrical Link to comment Share on other sites More sharing options...

For what you have now, you are fine. If you are going to throw out the kicker 750, and get a 2-3kw amp, upgrade your big 3 to 1/0 IF you upgrade your alternator.
