I see all these alts out their that are like 180, 200, 220amps But the idle is only 110-125 What the heck, so basiclly if i'm sittin thier at the light my car will still dim

So I got my kinetik hc1400 and installed it today, and then tonight my dad was like did you get a new alt too?.. I was like what omg?!? you told me not to invest in one in this car.. And he was like well I didn't know you were going to buy more batts, he's like you seem to need a lot of power so you might as well just get an alt.. I was like omg yay, SO.. Now I figure since he said I should get one, that gives me a good excuse to finally buy 1 I have dreamed of getting one for 2 years. So Im going to save up for one now but need help first, Alright.. Down to the point, I have no idea how many amps I need the alt to do for my system and I need a good alt because I don't …

I have a 2002 Chevy Silverado 1500HD that I have added the big 3 in 1/0 and a stinger spp1500d to. Inside I have a crescendo bc2000 powering a dc xl 12 d2 and a merlon meam50.4 powering my components and coaxials. While playing music with the bass up the low notes make the voltage drop. Sometimes down to the mid 12s from about 14.18. What can I do to fix this? Would an alt be the best way to go? If so what size and brand do i need? Also has anyone messed with the alts on dbelectrical.com?

I saw a discussion about this a long while ago on some audio site and can't find it again. I just wanted to know if there are any substancial advantages to running power wire directly from the alt to the back battery bank. For example: I have 4 runs of 1/0 running from front to back, 2+ and 2-. Right now, both + are running back from the + on my front battery. Would it be advantagous to run one run back from the + on the front battery, and the other from the + on the alt to the back battery bank? Advantages, disadvantages, not matter? My electrical will consist of 2+ and 2- runs of 1/0 from front to back, big 3 in 1/0, one 290 amd DC alt (2 in the future), g34 YellowTop u…

could i go wire straight from the alternator to the battery in the rear? the alt would also still be wired to the front battery as well. the car im installing is an 2000 honda accord. would i need to fuse after the alternator and before the batery in the rear? in my head this would work but ive never done it this way before...

well my stock alt (105a) is starting to chit out on me. at red lights, the volts drop real low, and the car sometimes will shut off then back on real fast....its not the batt, i tried it with my stocker, as well as a kinetik 2400. its prally when i played my powerbass xa3000d on the stock batt, and the alt couldnt keep up recharging the batt....

In an Alero, what kind of alt will I need to run a 4000W amp @ 1ohm with 4-600W for components? How many runs of 1.0 wouldn't be overkill? Will one battery stayed charged and properly power 4500ish watts? Big 3 of course. Thanks.

I will be needing to purchase either a 160 amp alt. or a 8-20 fared cap. eventually both. I have a voltage drop problem. My current alternator is only 80 amps. my amp , I think has 4 20 amp fuses, its a soundstream tr880/2. My headlights dim quite a bit. Would a 8 or 20 fared cap fix the problem well enough to forget an alternator. I can get a 20 fared soundstream cap on ebay for $169 new, $129 for the 8. Or should I go with the 160 amp alt. Which would be more effective. Most people I've seen have only a 1.5, 2, or the biggest I've seen in a car was a 4 fared. What do you know or think? This guy at a audio shop told me that if I were to replace all the major ground wire…

I have a 2000 Chevy Blazer(s10) I was wonderin if anyone could tell me what size alt. I need I will be runnin around 2400rms thankx for any help

hello all been awhile .. i have a question about alts i have 3 alts 2 for system the other powers the van. its a mecury/toyota van. yes mecury /toyota they called it mercury villager but made by toyota. im using chevy small case alts..they charge fine i only use the one wire off of them the sence wire. i dont use the dummy light wire.. now i was told that buy doing this alt.it would not draw power with sence wire connected to audio batterys . ive had many people argue the fact it does not draw power.. ook well this eve i was standing by my van and could here a slight wine.. i opened hood and related it to the alt sound was clearly from alt . second the alt is warm just s…

Hi have a problem have 2 saz 3000 amp strapped who master and slave, ven conect the master slave cabel i get alternator sound, just only ven strapped, anybody have a sulution??

just installed a brand new chevy alt on my mecury van , its chargeing but not fully i ran over my DMM so i cant test it till tomorrow.. theres 2 wires on the alt one is grey the other is white.. 3rd wire is the big red battery wire.. the gray im told is to battery power and white is a exciter wire but am told you dont have to use this white wire because at 1200 rpm itll turn on.. so a quick test and it was chargeing but i was using a test light for the time being and it was lit but not as bright as the vans own alt when i hooked it to van alt it was bright.. not as bright with second chevy alt .. any one have a clue why its not fully chargeing or am i missing something..…

as i was doing the big 3, i was looking for the engine ground, but it is in a very difficult place to work on, ill have to take a hose, some spark plugs, and other wiring to be able to connect the wire, is there any alternative to the factory engine block i have a 2000 silverado 4.3L

well i am looking for a good brand after market alternator, if you know of any help me out,

Holy s**t! How much are you guys paying for alts? I called H.O. Alts & to replace my stock 130 amp with an oem repl 210 amp is $699.00. That doesn't incl tax, ship, etc! BTW this is the only one that won't require any mods or interfere with ecu so it's the cheapest route. Just got sticker shock & wanted to see if this was an average price. Called a couple local places but thier alts require a lot of other hassels with stock elec system.

Will i need an aftermarket alternator if im running a hifonics bxi2608d? at around 2200~2400 watts in a 2000 Hyundai sonata with 1/0 power wires and Big 3 upgraded.....

so my question is, what size alternator should i need. i have 2 cvx122 kickers running off a saz2500d running at 2 ohms, custom ram-designs box, (which by the way is sweet and well worth the money ) 2 runs of 0gauge pos, 1 run of 0gauge neg, big 3, 1 d3100. its a 98 s10 4.3 x motor(hi output). i bought a 220 powermaxx but unsure if this is enuff. Any way to calculate if i need more or another batt?

Trying to figure out what size alternator I'm going to need and how many batteries I'll need. I'm figuring at least a 250 amp alt and 2 D3100 powermasters, plus a yellow top under the hood. Will be running a Clif Designs 4800.1lx and probably a Sundown 100.2 or 125.2. Is there a way to calculate what I'll need or is this all a guessing game?

so this kid on SMD claims that i should be ok with an 80 amp stock alternator running off an audio pipe 2000 together with a rockford 250.4 as it is i have major volt drop, have a yellow top under the hood and an xs power xp950 I'm looking forward into buying a singer alt 180 amps but trying to see if it'll be good even after i purchase a larger amp which I'm thinking about the soundqubed q1 3500 let me know what you guys think, should i stick to the 180 amps and still be good in the future? (still gonna purchase a second xp950 in the near future)

Is there a way to find out how much room is left in the alternator output after running the vehicle? I am just wondering if this would be a way to see or prevent power drops and messing up the car/truck electronics.

so i have 2 18" fully loaded BTLs waiting to be put in with 2 2400 watt rms hifonics amps....1 amp for each sub... but i need to know how many batteries do i need ?? also what brand / model ?? i know XS Power Batteries but which model ..im thinking the HC2400 for each amp ??. i wanna get 1 battery for each amp ... and then 1 battery for my cars electrical... also how many amps does the alternator need to be ... i know i need to upgrade the alternator.... im pretty sure i wanna go with DC Power alternator ive heard nothing but good things about them... what brand ?? where can i get the alternator ?? also what gauge does the speaker wire need to be ?? 12 gauge fine ?? im no…

Hey guys just trying to get a little info about some electrical from more experienced people. Im looking into getting a new alt, i have a 2005 chevy silverado 5.3L. Now i see iraggi has a 300 amp alt and dc power has a dual bracket kit that comes with a 185 amp alt, all in the same price range which would be best for me? Run a single big alt or have the 185 to the amp? Also i have a xs power d3400 as my starting battery, but i was wondering if i put a 900 cca as my starting battery could i put the xs power in the back and be ok? Cause i read something like you cant have two different sized batterys in the vehicle, i plan to run a crescendo 3500, just trying to see my best…

Ok so I understand that if you dont want to deal with upgrading your alternator, you put more reserve of power (aka batteries). However, I understand that if your voltmeter tells you that voltage is below ~12v, then you are running into problems. I have a question regarding this. Let say I play my music and I see voltmeter says 11.9v but I already have my main battery upgraded, and an extra battery. At that point of having 2 batteries, will my problem be easily fixed with ANOTHER (a third) battery or would I have to get an H/O alternator? Reason Im asking is because a group 31 is ~$300, and an alternator for most cars is also around that price. However, I have a BMW and g…

So while I was deployed to the middle east I acquired my car audio equipment. But now I'd like to know what amp alternators and batteries would work best for my system. I'll be running a 15 BTL off of a Soundstream DTR2200 which should push 2200 watts to 1 ohm. I'll also have a 4 channel Soundstream amp pushing 100 watts a piece to 4 6.5s in the doors of my Tahoe. It'll be ran off of a Pioneer deck. I've heard al lot about Optima batteries but have read mixed reviews on them. As far as alternators, I'm open to any decent brand that audiophiles have had luck with. Thanks in advance for the help.

Hey Gents, i am new at car audio systems and would like to know how the BIG 3 is done. Can somebody explain this to me please. I got a response in a list form but didnt get it. Some help please? Also, does this help with dimming?
