If I have two 400 watt RMS subwoofers what size amp do I need? How can you tell?
Probably 800 watts at half the rated ohms of one speaker. Your amp must be able to push 800 watts at, say, 2 ohms if these are 4 ohm speakers or 800 watts at 4 ohms if these are 8 ohm speakers.It will say on the speakers what the impedance in ohms is.Get an amp that is specified with 800 watts or over, at an ohm rating that is SAME or UNDER…half the ohm rating of one of those speakers.That's the answer here's a short ramble:Almost inevitably you will be running the two speakers in parallel. Whether you have two outputs on your power amplifier; or if you go into one speaker then go out from that speaker to the next; the connection you don't see inside the speaker with in and out or inside the amp is a parallel connection. Parallel connections divide the impedance (ohms.) It takes a bigger amp to handle lower impedance, because lower impedance is lower AC resistance. Lower resistance means more amps flowing for the same output voltage. More amps requires a beefier output section. The actual equation for total speaker ohms of speakers wired in parallel is:Total ohms = 1/((1/ohms#1)+(1/ohms#2))…If you put in a third speaker there would be another similar term in the denominator, (1/ohms of speaker #3). More speakers, lower ohms…The amp will say what the watts and ohms are on the back, or at least in the manual it will tell you what it can handle. Be at or below the ohms, and above the watts.
What size amp do i need if i drop 2 ohm subs down to 1 ohm?
Did I read that correctly? You are going to use 4 of those? In that case, you want a mono block, and it would have to be 1 ohm stable. The subs are rated at 1000 watts RMS each, (RMS is all you need to worry about ignore peak) so you would need an amp rated at 4000 watts RMS @ 1 ohm. This would be rather expensive, so you would probably be better off with multiple amps. Now comes the real problem, supplying power to a 4000 watt system, your car would require significant and expensive upgrades to the entire charging system, and electrical system. you may want to rethink this, if you want to avoid these upgrades, depending on your car, limit your total system power to 1000 to 1500 watts RMS.
What size amp do i need for my 2 15inch subs?
is that 1500 rms? you can run the subs off any size amp, if you run the watts too far below the rms then you can do some damage to your subs in the short/long run, its always better to have just a little bit more power then the rms. so you can use the 1900watt but your losing power on the sub
What size amp do i need for 2 12" sony xplod subwoofers (SON XSL124P5B)?
you go by rms. for these i would go with: Kicker ZX-750.1 Mono Channel Amplifier Details: RMS Power: 750W x 1 @ 2 ohms RMS Power: 375W x 1 @ 4 ohms THD at 4-Ohm RMS Power: <1 % Speaker Level Inputs Preamp Outputs LP Built-In Crossovers Bass Boost: 0 - 18 dB Frequency Response: 25-200Hz Signal to Noise Ratio: 62 dB Advanced chassis with extruded aluminum heatsink Efficient class D circuitry Top-mounted controls KickBass 0-18 dB variable bass boost at 40 Hz Variable 50-200 Hz low-pass crossover with 24 dB/octave slope Defeatable 25 Hz subsonic filter High level or low level inputs (125mV-10V) PreAmp Signal Transfer (PAST) RCA outputs Delayed turn-off logic circuit Soft start turn-on circuit for reduced startup load Short circuit, Over-voltage, Reverse polarity, Thermal overload (SORT) protection Included remote KickBass control Fully CEA-2006 compliant specifications for real-world power here is a link: http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=16918
What size amp do i need to power 2 12 inch subwoofers?
500 watts, buddy, isnt the actual power. You look at Watts RMS, Rms is the continous power, those subs each could only have true power of say 175 watts rms. Get a 900 watt amp, make sure it is RMS watts, not peak or max
How many Watt Amp would I need to push 3 12 inch subs?
i had like a 100watt amp set up with two mtx 12" subs, and my friend gave me another 12" alpine, and a different amp which i think is still just 100w because mine wasnt a 2 channel, if i hookup both subs they arent getting enough power, whats a good amp to push these 3 subs?
Is it bad for the wiring kit to overpower the amp/subs?
The larger 0 gauge wire will not add any more stress to your amp or alternator than the smaller 4 guage. In fact if you use the smaller 4 guage, you would be adding more stress to the amp since you would be restricting the power flow to the amp. Keep in mind the ground that you use needs to be of the same guage as the power. If you use a smaller ground than power, you will restrict the power. What comes in must go out. Your biggest problem here is the alternator rating. At only 95 amps, you will be stressing it with the amount of power the amplifier will be requiring. Not the power wire. Adding a capacitor will not reduce this draw on the alternator. In fact, it will add to the draw. The capacitor only assist in providing the power to the amp at a quicker burst rate. What this means is that it charges at a quick rate, then discharges when required by the amp at a equally quick rate. However, it still needs to pull the power from the alternator. Adding a second battery will assist you in reserve time while the engine is not running but also will add to your draw on the alternator. I would highly recommend that you consider upgrading the alternator to at least 150 amps as soon as possible. These can be found a numerous places such as your local stereo shop to even in a J.C. Whitney catalog. Although not cheap, they will be the best investment you can make in a high output stereo system. The fuse link that you are using on the power line should not be any higher than your total amperage draw from all your equipment. I.E. the amplifier(s), capacitor(s) and so on. You should check the specs on your amplifier to see what it recommends for the fuse size. If you are using multiple amps, you add all of the fuse sizes together. Some capacitors will also list an amperage rating which you would also add if you are using one. The fuse link should also be no greater than 12 inchs from the battery or alternator if you connect it directly to it. In conclusion, use the 0 guage wire. It will not hurt you. Look at upgrading the alternator because the amplifier will draw more than you can provide at current status. Choose the proper fuse size based on your equipment needs. By following these guidelines, you will enjoy years of audio from your equipment without failure. T.G.P.
What size amp and wiring would i need to run two SOUNDSTREAM T5-15's ?
Ok I have an answer to ur problem! First ur gonna wanna get the high capacitor as well as have ur alternator tuned up on amps to protect the value of the car or in another case get a deep cell battery! As for an amp I reccomend either of these brands Kicker, JBL, JL Audio, Or Memphis! The rest have at some pont in time been bought out by other companies and arent as good in quality as they once were! Example Rockford Fosgate has been bought out and now there amps and subs are ****. As far as wattage be on the safe side since ur subs handle a max power of 1000 watts each go with a 1500 to 1800 watt amp as to not over do it and blow ur subs. If u wanna go max power I recommend buying either Kick Solar Barricks or JL L7's
