Can I run both the amplifiers on the same 2 gauge wire running to there full capacity even if I have to But a capacitor and if so what fared?
There currently is no fuse/block to protect the battery, AKA the "main power source", only a fused distribution block totaling 150 amps! Sundown recommends a high output alternator and additional battery for this amp, and goes on to say "a factory electrical system is NOT capable of supporting [this amp's] current draw demands. I'll throw another curve your way. 500@4ohm
My question is, should I run 4g off the distribution block to each of the amps as well as from the battery to the distribution block? But I'm a little confused on the total RMS thing. Also note that 00, 000, and 0000 gauges (generally refered to as 2/0, 3/0 and 4/0 are progressively larger in size and are represented in the Wire Size Calculator as -1, -2, and -3. You'd also need a 200-amp to 250-amp fuse to protect your wire and vehicle from fire in the event of a short circuit. 4 x 75w @ 4 ohm
Should you rate the wires from the distribution block to the amp separately? John, According to my figures and the stats I can find, those three amplifiers will together try to pull as much as 207A from the electrical system, and 2-gauge wire may be a bit too small for that, unless it's a short run. Jeff, Sounds like you have your power wire requirements covered. If you plan on adding an amplifier with a total output of 110 watts RMS, then you will need a 10-gauge (2.59 mm diameter) or a 12-gauge (2.05 mm diameter) amp wiring kit, depending on the length of your installation. #3 wire has an ampacity of 95A, it used to be "close enough" for 100A services on homes, but that got changed to #2 which has an ampacity of 125A. Yahoo is part of Verizon Media. Crutchfield customer service is outstanding. Second I just bought another t1000.1 and was wondering if the kinetic 2000 is enough and is the 2 gauge from the front battery good enough? And be sure to mount it as close to the battery as you can. Should i also have fuses at distribution block? If it's an AB amp, then maybe 2/0-gauge cables will be needed. What AWG would i need for this setup. But if the chart could lean either way between two sizes, going with the larger wire size would be the smart choice. David, Seeing as you are the second commenter who read that "divided by" sign as a plus symbol, I am going to rewrite the formula in English, with no mathematical symbols. Joey, Without knowing the specific model amplifier I can't be sure, but if your amplifier really is capable of putting out 1600 watts RMS of power (RMS not peak), according to this article's formula and chart it needs either 2-gauge or 1/0-gauge wiring, depending on the length. Keep up the great work! block and then 4 ga OFC wire to the amps. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience. So 100A total. So im guessing the door speakers will see about 90W each. ... you connect 6 or 4 gauge from your battery to your amp from your battery terminal. I'm using a Kicker 4g wiring kit with a 100amp fuse. The fuse holder showed signs of heat and the wire in the clamping part/set screw of the holder was brittle and broken. There is never a problem running a speaker or sub with less power than its rating, as long as you don't send it over-driven distorted signals attempting to get more volume out of it than the amp can deliver. The distance from the fuse block to the amps would be less than 2 feet. 1800 watt amp on 0 gauge wire... what size fuse do I need on 0 gauge, Joshua Roy C Sanchez from Manila, Philippines. Hi Buck, impressed with all the knowledge sharing here! Sub: JL Audio 10W3V3-2
Alpine PDX-F6 (150 x 4 RMS = 600W) powering:
Jason, If you're referring to a Rockford Fosgate Prime R500-1 amplifier, it won't work well with a 1-ohm load, and will probably go into protect mode before overheating. *** Although wire gauge sizes smaller than 10 gauge may be acceptable for the amount of current draw, we recommend using 10 gauge as the smallest wire size for any amplifier of 100 watts or more. I want to be able to push my subs to their full 2400 watt capacity without causing damage to my alt or battery(ies). My amp also had an RMS output of 1200w x 1channel at 4ohms but states bridged. Normally, the amp requires 4-gauge power and ground wiring, but for your short runs 8-gauge or 10-gauge will work as well. I own a 2000 dodge neon manual 2.0l. There are many ways to connect subwoofers to an amplifier. They will be pushing two 12" Cerwin-Vegas. Why is it that all your recommendations exceed what is considered safe in 310.15 b 16. Maxwell, In this case, yes, you should figure each amplifier's power and ground cable requirements separately. Two 15 ampere fuses does not, a 1,200 watt amp, make. That means that the voltage divider is more like 30:40, or 75 watts from the 100 watt amp output is making it to the speaker. Sounds like you have room to add a bunch of bass. I have a volfenhag element-5 2600 watt full mosfet monoblock amp wanting to know true rms of it and if it is 1 ohm stable or can power four svc subs two of them are 400 watt rms the other two are 300 watt rms can i run it parallel and be ok. Lots of good info here,but I just want to double check. Don't knw what's happening? Could you please point me in the direction of potential causes? For this you will want to use 14ga wire for this. I would not even consider getting a capacitor unless, after the whole installation was done, the headlights dim when the music hits hard. I went through a lot of problems thinking I had smaller wire because my protect was going off. What that means is the total impedance of the subs, in ohms, is lower than what the amplifier can handle. To use the chart, you'd figure it for a current draw 150% larger than usual. Their toll-free number is on your invoice. Pankaj, Most stock vehicle system have about 15 watts RMS output per channel and use 18-gauge (1.02 mm diameter) wiring. Your figuring is correct: you can use 100A fuse at the battery and a 60A for the sub amp and 40A for the 4-channel.
But if the amp is only 50 watts, 16-gauge would be fine. Thanks. From where are you people getting a need for these huge wire sizes? Here's the board tpa3116d2 specs the amp is using. Ill get right on that as I have not pushed it in the slightest yet. 99.9% chance that wattage rating is the "max output" rating, which may happen in small increments. Will, The fact that your amplifier is blowing 300-amp fuses should tell you that something is wrong. If you want to drive two 2-ohm speakers, or want to bridge the amp to run a 4-ohm subwoofer; 400 watts RMS x 1 channel; 400x2/13.8 = 58 amperes; you'll want 8-gauge or 4-gauge wiring, depending on the length needed. However, you should be aware that some brands of wire don't meet the same standards and over-state the size of the conducting wire inside the insulating jacket.
Sorry if that's unclear. Bryan, Without knowing precisely what vehicle, what its factory system consists of, and what upgrades you want, we can't help you with system planning. Take into account all corners and risers. Hello Buck, I have POLK PA D4000(125RMS @4OHM) and JVC KS-AX3101D (400RMS @2OHM). ;
I think my math might be off but I arrived at 460 amps which isn't listed. You could upgrade to 4-gauge cable, so you wouldn't have to re-wire if you got a stronger amp in the future. Davey, That amplifier needs 4-gauge power and ground wires and a 100-amp fuse on the positive wire near the battery.
It could be that the power ratings were exaggerated by the manufacturer, a common occurrence, and you won't need cables that large at all. And an alpine 300watts.4 channel..i was thinking of running 2 or 0 gauge from the battery to the distribution block in the trunk and from there keeping my true 4 gauge wires to the amp. From the block I have 4 ga going to an audiopipe apsm 1500 at 1 ohm doing about 1400 watts rms and from the block 8 ga going to an autotek 1000.4 with 4, 4 ohm door speakers. I'm running two apms. And thanks for your help. I have four speakers all Kickers that have 60 watts rms. My wire is not cut down due to having the Caps and I actually added an extra 5 feet or power and ground to accomodate both caps for placement. It'll be easiest with a fused distribution block. My front speakers are 90watts rms and the rears are 60watts rms. comp sub. Austin, For your high-power application I recommend using 14-, 12-, or even 10-gauge wire if it fits. I am installing a Hertz HDP4 amp, it is a full 17 Ft cord length right now. If you're asking about the amplifier's power and ground wiring, 8-gauge is what its specs call for.
It's a class AD amplifier so I'm unsure how to calculate the correct power wire gauge. Chances are it won't ever hit that rating. Thank you! So if the amplifier is putting out 400 watts, it's actually drawing about 533 watts of power from its source, and the amp's wiring needs to be big enough to handle that draw.
I just got a Kicker CompVR 43CVR124 with a Kicker CXA400.1 amp. Product Overview. Let me know if I missed any details. To handle this higher current, it is recommended to use an appropriate power wire during your installation process. Matt, If the wattage you quote is watts RMS, then 8-gauge power and ground wires will work in your application. Capacitor: 1.5 farads
Estimated wait for next available agent : We’ll email you a transcript of this conversation for your records. I will just get a different one that plugs into cigarette lighter. Ok I will list components and see what you think. Plugging that number into the chart at 7-10 foot length shows that you can use 8-gauge power wire from your battery to a distribution block. You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. MRV-F300 will be 50 watts by 4 configuration. Dustin, I would use 1/0-gauge power and ground wires for that amplifier seeing it has 200-amps worth of fusing. Thanks!! 1 star 2 stars 3 stars 4 stars 5 stars. Otherwise, I'd use 2-gauge power and ground wiring. Crunch PX 1000. Thanks again! I'm just hooking up a basic system with 6 x 9 speakers for now. For 4-gauge wire, use an 80-125A fuse. Wires that connect an amplifier's output to a subwoofer should be anywhere from 16- to 12-gauge in size. For consumer safety reasons, this article uses calculations based on a typical Class AB amplifier, which are usually about 50% efficient. Is the chart you provide for OFC or CCA wire? Sheri, It sounds like your wiring kit is too small for that amp. The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. Amp is an outdated Alpine 4 channel that puts out 70rms/channel at 4 ohms and 100rms/channel at 2 ohms. The fact that you say you've blown an amplifier and now they're running hot tells me that you're trying to drive an impedance load lower than what your amplifier can handle. I'm about to overhaul my Pontiac G6 system, including new main speakers and stereo (pioneer AVH-X4800BS). Don't forget the inline fuse near the battery. Can i use an 8 gauge power wire for an 1000 watt amp 2 12 p2? In other states where we don't collect sales tax, it may be the customer's responsibility to assure that all appropriate state use taxes are paid. Do I need to drop down to a -0- gauge kit, or larger if necessary? Now my car was made with the battery located in the rear of the car. alpine also i am using the biggest power wire the stereo shop had which is big but not sure what gauge it was. Questions:
