i got a saz-2000 watt amp going to 4 kicker l5 15's, my electrical upgrades are 1 optima yellow top battery 2 runs of 1/0 gauge total 1 pos 1 neg, big 3 upgraded to 1/0 gauge, 200 high out put alt, and 1 die hard platinum p1 in the back, i will be running the amp at 1 ohm, people have told me that i should have much voltage drops others tell me i will, what do u guys think, and i want to get a voltmeter just incase how dou you wire it in

hey yall, i just wanted to get your opinions on the volt meter i have. i actually bought this Autometer voltage gauage quite a few months ago for around 60$ (msrp 120$) and um i thinking should i get that install for my system? or should i get a digital one since this one is a gauge and it doesnt tell u the EXACT voltage.. and if the digital one.. which one should i buy? no one near me seems to be selling it less then 100$... thanks!!

I really have all green lights in my truck and i think having a volt meter on the dash or center console or whatever would be pretty cool. Everyone seems to have stinger volt meters.. They dont come in green that i have seen so i have seen some "slim volt meters" or something like that... Do they work good? And how do you actuly attach them? Any comments will be productive. Btw... Ik its only like 6 bucks but i dont have a credit card so would be a hastle to get it especially if it isnt worth it. Thanks for any commenct

i was @ Harbor Freight and saw an analog Volt meter that bosted different color LED's for $19.99 so i got a lil help from Alan Hall and well minus 1 smaller cup holder later... 3/4" Mdf wrapped in Blk Vinyl heres the installed pic off on with motor off on with motor running different colors not bad for a cheep fixx, waiting for Stinger to replace my digital volt meter. http://www.harborfreight.com/cpi/ctaf/disp...temnumber=98479

Anyone know of any good ones? Not like a hand held, like one I can look at while I'm driving or sitting in my seat or something. Like this stinger one, but I just want to see what others there are, and your opinions on some you own... http://cgi.ebay.com/STINGER-SVMB-VOLTMETER...8QQcmdZViewItem or http://i107.photobucket.com/albums/m303/cH...cs/P1020013.jpg (bottom of the pic)

i was wondering if any one could help me by telling me were i could get a in dash volt meter? i have been searching on line and for some reason cant find any only batt terminal volt meters also any recommendation on some brands ? i was thinking stinger put like i said for some reason cant find any mayb im doing something wrong

So , I just noticed that my power cap volt meter is droping to around 11.04 volts when I have my system pounding to its potential - can anyone tell me what to look for as the problem with this - 11.04 cant be right , its usually around 12.5-13.4 , and it drops that low for only a second . My setup is this : Red top under my hood -> isolator -> yellow top in the trunk -> 1.2 farad cap -> amps " Kicker 4ch 70x4rms " , and " Orion 2400D 1200x1@1ohm " . The cap has been grounded seperately from the yellow top - they each have there own , my system is running 4 ga. wire , power and ground .

When I accelerate really quick my voltage drop to like 12.Didi not do this before big three. Any ideas?

Tested voltage drop with most accessories off last night. At idle the car rests at 13.9x, With a variety of music and an Iasca test disc, at the loudest volume i can play the factory stereo at while still sounding decent, the lowest i got it to drop was 12.69, it was mostly between 12.7xx and 12.9 on HARD hits. Electrical system is stock, battery, alt, etc, all stock, no cap/ 2nd battery, extra 0wag ground under hood to battery, extra 4awg ground running to rear of the car where it joins the 1/0 that goes into my amp. Amp is an MTX 81000d running @ 2ohms, Rated 1krms @ 12.5 volts, most people get between 12xx and 14xx on their birth sheets at that voltage. I was just surp…

I have a feeling this is a pretty common problem that some of you have dealt with. So hopefully you can help me. I have a Fi BL 12 running off a sundown sae1200d. And when I play it at full tilt at idle, I get voltage drop into the 13.0 range (and sometimes even a bit less D:) Although when driving or holding the revs at about 2k, the voltage has no problem sitting at 14. I'm pretty sure this is an alternator issue. But ive heard that even HO alternator have poor output at idle. So what do I do? FYI- big three is done. And all wiring is in 1/0 Also, I currently have a quote from Excessive Amperage for a 200 amp alt for $385. Thanks in advance.

Alright, so I've done some searching and can't find any posts similar to what I'm dealing with. The closest I can find on google is something referring to the battery current sensor. Aparrently its only on 2005+ Tahoes though, but it senses draw and adjusts alternator charging output accordingly. Mine is a 2000, and when I went through my Big 3, I saw no such sensor as expected. The issue I'm having is a lot more noticeable now that I have a Stinger volt gauge in the dash (Installed same time as new HO Alt, 9/11/19) When I start up, I'm at around 14-14.3v.. after warmed up, 13.9v is consistent. Now... I've notice multiple times that when I am coming to a stop, or slo…

I have 2 fi SSD woofers in my 2001 Celica and the lights dim real bad every time the bass hits. I have a 2.4 farad capacitor, is that even worth putting on? or should I go for a new alternator or battery

i have an 03 mazda protege dx...it's i tiny four door car similar to a civic in size....the alt is a stock 80 amp the problem is they do not make a HO alt for this car...i have one yellow top under the hood and i guess it's getting old now considering the voltage is getting lower when i am hittin hard.. i do have s 2.5 farad cap and i know it doesn't cure the problem! but i'm afraid of adding another battery in the trunk because wouldn't that make it harder on the altenator to charge 2 batteries?? Amp is a titanium 2400 Subs 2 15" fi Q's voltage drops to like 11.8 to 11.3 the lowest! any way of working around this? or do i need to add another batterie?

So lastnight I installed a digital volt meter in my dash, and today I noticed that when starting the car it reads around 14.5v, when not running it reads around 12.8v...However driving around a bit I see my voltage drop down to around 12.8v, not staying at 14.5v, even if I'm not pushing my subwoofers... Is this normal? I assume it has something to do with the alternator?

Hi 99 Oldsmobile Alero Yellow optima up front and one in the rear Powerbastards 220amp alt knu 1/0gauge (+ and -) front to back, big3 as of today. no fuses. problem persists Im getting a drop from 14.4 to as low as 13.2 when I bring the car to a stop Sometimes it stays at 14.4 when I stop but most of time it dont 13.2 is about as low as it gets, its random and sometimes doesnt drop at all I only get this reading from the rear battery I dont have any of my amps connected, no sound, still a drop The rear battery is grounded to the negative in the front I have also tried grounding the rear battery to the point under the seatbelt bolt that i have used before (no luck) The fr…

I was wondering if anyone can help me with this. I drive a 2005 colorado with a HO 200amp alternator with a deka intimidator group 34 under the hood and 2 group 31's in the bed. The big 3 is done in 0 gauge, Two runs of 0 gauge to the rear batteries. I measured the voltage at the amp. At 1/2 tilt I was at 13.4 at idle, as soon as I turn it down it jumps back to 14.4. As soon as I crank it to full tilt it drop to 11.6 at idle. My amp is saz3000d at 1ohm. I think I covered everything. Do I have a problem somewhere or do I just need more. I didn't want to piss the neighbors off too much because so I will have to measure the voltage again at 2000 rpm to see how much differenc…

So far I'm loving the new system but I've noticed with some songs (the loudest) and also at idle my voltage can drop down to 12v. It always jumps back up to 13.8+ volts after the bass hits... Should I be concerned? I still need to upgrade a ground under the hood, hoping that will help a bit.

I have an 01 tahoe with 2 15's kicker cvr dvc 4 ohm wired down to 1 ohm. Us amps xt 4000 1500rms@1ohm and a crunch 1400 4 channel and a 4 farad performance teknique power cap. red top under hood and db electrical ho alt. Have not did the big three yet. At idle my voltage drops to 13 or even 12 when bass really hits. Will the big three help with 0 gauge wire. Should I buy a powermaster D680 or D975 and get rid of the cap

this weekend i worked on the car some. i installed my voltmeter, when i installed it it said "LO" figured cuz the car wasent on well i was working on it and the batt drained some. so i hooked up a charger and let it charge well i finnished wireing my active front stage and my sax100.4. when i was done i turned the car on and i had nothing playing at all. volt meter went up to 11volts, i drove around and the highest it goes is 11.4. i have the big 3 done. i have an optima g35 under the hood 720 cold cranking amps. when i stop at a red light it drops down back to "LO" witch is under 10 volts. i have an 06 envoy. when i was running my wires and installing everything i notice…

So i'm sure many of you have heard this question before but i cant seem to find a good answer.. I'm running an Fi bl 15, on a sundown sae 1200d in my scion tc. Big 3 is done. Stock battery is some kind of panasonic. It seems that its not regenerating power quick enough or something. I will start my car in the morning and be at like 13.8 volts, and start it up a few hours later and be at like 13.4 upon startup. I want to be at a consistent higher number than this. Also how can i prevent my voltage from dropping so low when at loud volumes, getting tired of seeing it drop in the mid 11's and having to worry about it. I was going to get an optima yellow top but dont really …

I currently have 2 Kinetik HC2000's in my Tahoe, one under the hood, one under the back seat maybe 15" of power cable away from the amp. Have a db-starter-aternator 220A alternator (which for some reason i cant locate the one i bought from them.. maybe they stopped selling it? lol) It listed it makes its power at like 1200 RPM or something.. should have never bought it.. but thats what I have, I took the voltage meter outside today and looked at both battery's.. Car not started in over 24 hours the battery under the hood was sitting at 12.6 with the vehicle off.. back battery at 12.5. turned the vehicle on which had the rpms at like 1300 or so since it wasnt warmed up.. s…

Whats up everyone, alright so i came across this voltage meter on amazon today and was wondering what you guys think of it. Its a ciggarette lighter voltage gauge. Do you think it would be accurate? If not how off do you think it is and why? i know the cig lighter is hooked straight up to the battery and its a 12v lighter but will this volt meter be accurate at all? here it is http://www.amazon.com/Equus-3721-Battery-Charging-Monitor/dp/B000EVWDU0/ref=sr_1_3?ie=UTF8&qid=1307664465&sr=8-3

I have a xp2000 in the back and when I bought it I put it in my car and it charged at 13.1 or 14.4 @ 2k rpm. A few days ago when I turned my car on my voltage was at 13.1 like it normally charges at but when I revved the engine it wouldnt charge to 14.4, it slowly then dropped by .1 around per day until I unhooked it because it got to around 12.2. So I checked my connections and grounds and saw no problems. I then looked at the front battery and it was charging at 13.1 and 14.4, but the xp2000 in the back does not charge when its hooked up. So I hooked it up to a charger overnight and it read about 14.4 in the morning and unhooked it, I then went to work and came back…

so i got: optima yellowtop under the hood kinetik hc2400 on the back iraggi 240/165 amp alternator it was running fine for about a week since i installed it, my voltages were: 14.2@idle, 13.4v w/ engine off this morning it was running fine too so when i was leaving this afternoon, i noticed the battery gauge was pretty low i checked the voltage and it was only 12.7 while the car is idling and system is off so i turned my car off and checked the voltage, it was 12.8 so i disconnected my powerwire that runs to the back battery and the amps after about half hour driving i checked the voltage, while idle it was 12.3 when it was off it was 12.5 what do you guys think? did my …

Hey guys, so i'm at a stump with my electrical in my car. I have two sundown SA-15's in my Honda CRV being powered by a hifonics HFI 1500d. I would love to upgrade my amplifier and get about 2500 watts to the subs but my voltage is too low for that type of power. I have been searching for a compatible high output alternator with the CRV for a while now, but have had no luck. Also the alternator is located under the engine so I would have to pay a shop to go in there and install it. All lots of money i don't have to spend. Are there any other ways i can give my electrical system a boost to maintain that 13.8+ to power a higher wattage amplifier? I have already done the big…
