No. Reducing the resistance of a sub woofer effectively means that more power is available from the amp. It does not improve power handling of the sub itself. In order to improve power handling of a sub, you need to improve its ability to manage heat.
In the audio industry, companies generally improve heat management by giving their subs large diameter voice coils and more massive magnets. The large voice coil provides more surface area from which to radiate excess heat. The more massive magnets provide both greater magnetic field strength and more mass with which to absorb the heat from the voice coil.
Mr. Van said: The impedance of the speakers must match the output impedance of the amplifier or there will be wasted power loss, usually converted to heat. This heat sometimes damages the output transistors or integrated circuits in the amplifier, or the speaker, or both. Some amplifiers have protection circuits that may prevent this by blowing a fuse, tripping a breaker , or just reducing the output power.
What else can I help you with?
You have an Alpine type X 1243D subwoofer you are trying to decide if running it at a 2ohm load at max power or a 4ohm load at two thirds of its power range will work better?
Multiple subs wired together must be the same coil type and impedance. If they’re not, the power won’t divide evenly between them, and some subs would probably be over-powered while others get under-powered. If you want to run different types of subs in a system, each type needs to have its own separate amp. Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating. Figure out the possible total impedance(s) that the subs can be wired together to form. (SVC = single voice coil, 1 pair of terminals; DVC = dual voice coil, 2 pairs of terminals.) 1 SVC 2-ohms can only have 2 ohms of impedance 1 SVC 4-ohms can only have 4 ohms of impedance 1 DVC 2-ohms can have 1 ohm or 4 ohms of impedance 1 DVC 4-ohms can have 2 ohms or 8 ohms of impedance 2 SVC 2-ohms can have 1 ohm or 4 ohms of impedance 2 SVC 4-ohms can have 2 ohms or 8 ohms of impedance 2 DVC 2-ohms can have 2 ohms or 8 ohms of impedance 2 DVC 4-ohms can have 1 ohm or 4 ohms of impedance 3 SVC 2-ohms can have 6 ohms of impedance 3 SVC 4-ohms can have 1.3 ohms of impedance 3 DVC 2-ohms can have 1.3 ohms or 3 ohms of impedance 3 DVC 4-ohms can have 2.7 ohms or 6 ohms of impedance 4 SVC 2-ohms can have 2 ohms or 8 ohms of impedance 4 SVC 4-ohms can have 1 ohm or 4 ohms of impedance 4 DVC 2-ohms can have 1 ohm or 4 ohms of impedance 4 DVC 4-ohms can have 2 ohms or 8 ohms of impedance Look for an amplifier that can put out power up to the RMS wattage at an impedance load the subs can be wired to form. 8 ohms — figure on the amp putting out half the power it would at 4 ohms 6 ohms — figure on the amp putting out three-quarters of the power it would at 4 ohms 3 ohms — figure on the amp putting out the average of what it would at 2 ohms and at 4 ohms 2.7 ohms — figure the same as for 3 ohms, and add a few watts 1.3 ohms — use the 1-ohm spec and take away a few watts Example: You have two Alpine S Series S-W8D4 8" subwoofers and you want the right amp for them. They are DVC 4-ohm subs rated at 300 watts RMS each. Two 300 watts RMS subs together need a maximum total of 600 watts RMS. Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a 16-ohm load. The last is too high a load to be practical, so you’ll look for an amp that can put out up to 600 watts RMS into either a 4-ohm load, or a 1-ohm impedance load: up to 600 watts RMS x 1 at 4 ohms, or up to 600 watts RMS x 1 at 1 ohm Among Crutchfield’s selection of amplifiers you’ll find: Memphis Audio PRXA600.1 — 600 watts RMS x 1 at 1 ohm JL Audio JD1000/1 — 600 watts RMS x 1 at 4 ohms Kicker KEY500.1 — 500 watts RMS x 1 at 1 ohm Any one of these high-quality amplifiers would work well with those subs. It doesn’t matter which impedance an amp plays through — 600 watts RMS through a 4-ohm load produces the same volume as 600 watts RMS through a 1-ohm load. You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms. Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms. Two subs on a 500 watts RMS amp will want about 250 watts RMS each. So you’ll look for subs each rated for 250 watts RMS or more. Using the chart in Step 3, for two subwoofers, a final 2-ohm load can be achieved with either two SVC 4-ohm subs or two DVC 2-ohm subs. So, you’ll look for two subs that are either SVC 4-ohms or DVC 2-ohms, rated for at least 250 watts RMS each: 2 SVC 4-ohms, at least 250 watts RMS, or 2 DVC 2-ohms, at least 250 watts RMS Among Crutchfield’s selection of subwoofers you’ll find: You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms.

Dual 4 ohm subwoofer what kind of amp should you use?
4 + 4 wired in paralell + to + and - to - will give you 2 ohms. do this on both subs and then wire them together + to + and - to - and that will give you 1 ohm. so now get an amp that is 1 ohm stable 95% of mono block amps are. add your subs rms wattages together not peak let say your subs are 1200 peak and 600 rms then 600 + 600 equals 1200 watts rms is what you need. so for this instance i would need a 1200 - 1500 watt rms mono block 1 ohm stable amplifier. I like more power just in case after the subs get broke in they want more power.
How can I add a subwoofer to a PA system effectively?
To add a subwoofer to a PA system effectively, connect the subwoofer to the main mixer using an appropriate cable, adjust the crossover settings to blend the subwoofer's low frequencies with the main speakers, and ensure the subwoofer is placed in an optimal location for balanced sound distribution.
How can you add a subwoofer to a Pioneer T1808 receiver in a Scion xD?
To add a subwoofer to a Pioneer T1808 receiver in a Scion xD, you'll first need a powered subwoofer that has speaker-level inputs or a line-level input. If using speaker-level inputs, connect the subwoofer's inputs to the receiver's rear speaker outputs using appropriate wiring. Alternatively, if the subwoofer has a line-level input, use a RCA Y-splitter from the receiver's pre-out to connect to the subwoofer. Ensure that the subwoofer is properly tuned and positioned for optimal sound quality.
What is the resistance of a parallel circuit with resistance of 2 ohms 4 ohms 6 ohms and 10 ohms?
R = 1/[1/2 + 1/4 + 1/6 + 1/10] Add up the reciprocals of the resistances, and take the reciprocal of the answer.
A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?
In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms
What is the total resistance of 15 ohms?
That depends how they are connected. For example, if they are connected in series, just add the individual resistances.
What size amp do you need for 6 and a half Sony speakers that has 190 Watt peak power and 40 rms and Sony 6 by 9 speakers that has 300 Watt peak power and 60 rms?
200 RMS 4 channel or 2 channel so u know add the rms of the speakers to find the amp rms needed
Can you add a subwoofer to a factory Jeep liberty stereo?
Yes, you can add a subwoofer to a factory Jeep Liberty stereo. This typically involves using a line output converter to connect the subwoofer to the factory head unit's speaker wires, or by using a subwoofer amplifier with a high-level input. Make sure to choose a subwoofer that fits your space and power requirements, and consider upgrading the vehicle's electrical system if needed to support the additional power draw. Professional installation may be recommended for optimal performance and integration.
