Twonames- well it all depends on what your receiver takes for a load,look on the back and most of the time the speaker impedence is marked.If you don,t see any then I would suggest 8 ~16 ohms.This is generally the average range,hope this helps you . cooltek Mar,15/08

I got 2 10in kicker comps and the rms on them each is 150 watts and can i hook them up to a 1000 watt sony xplod 2 channel amp and do i use both channel or just one or bridge them


1st thing is amps outputs have to be properly "loaded" this value is given in "ohms" if your amp says minimum speaker "loading" impedance is 4 ohms ( I suspect it does) then you may load that 1 channel down to only 4 ohms or amp will be damaged , most speakers are rated in ohm's Impedance (look for Greek symbol for omega) look for its rating somewhere on it doing the electrical formula math if you connect two 4 ohm speakers in parallel to one channel ( +=+ / -/- ) this divides down to 2 ohms (not good) but if you take same speakers and connect in series together (+to-/+to-) this gives you eight ohms (better) , the watts rating is a figure for you to determine the amount of power the speakers will take before failure , hence just because you connect 200 watt speakers to a 2000 watt amp is no indication that speaker will take all 2000 watts ( it will fail long before that point ) watts do ADD together like the above example two 4 ohm 250 watt speakers connected to one channel of amp in series will look like ONE 8 ohm 500 watt speaker to amp of course over 16 ohms load speaker volume will greatly diminish and amps have max impedance loads for them as well although there not often published
this is why I love the old TUBE!!! amps they load all the way down to 2 ohms and go up as far as 32 ohms load with no problems , they sound better as well across the board as well

Trying to connect 4 dual boss 12 to a 5500 boss class d amp


You can only connect an amp which has an output of 8 ohms to speakers that are 8 ohms are greater. You must NOT connect to speakers less than 8 ohms.
If the amp is 4 ohms you can connect speakers of 4 ohms or greater.
If the amp says 4 to 16 ohms then you can't go lower than 4 ohms.
As long as you stick to that rule the choice of speakers is up to you.

Speaker buzzes but it plays no music


Blown speaker driver. Buy a new speaker of the same frame size and ohms (Omega character symbol) usually 4, 8 or 16 ohms. Contact the manufacturer if its an expensive name brand. Check the manufacturer's literature to determine the Ohms, it will be listed. You have turned up the speaker too loud and fried the magnet. Buy better speakers rated in watts RMS... the higher the number, the better.

I have a Makita BMR100 radio. Stock speakers are 3.25" 8 ohm with an 8 watt 8 ohm amplifier. I replaced speakers with better 4" 4 ohm but they're not really compatible with an 8 ohm amp. I...


Buy an 8 ohm speaker and wire it in series-parallel look up images of of combination series-parallel wiring this allows wiring all speakers and keeping the 8 ohm loaf on the amplifier. Should get more linear volume between speakers. Not sure if replacement is worth it, those speakers are pretty good and work well with rain and jobsite conditions. I am planning to install some 8 ohm half inch tweeters on my Makita radio and using the series parallel wiring. Plead note series-parallel wiring is not series wiring or parallel wiring. It is s totally different way of wiring it that uses both names.

I have a pioneergm-d8500m amp and it stopped working and the green led just flashes.. i bought a new amp to replace it and it just does the same thing.. what is going on to cause this


crossed speaker wires or loose strands creating a short circuit, improper speaker ohmage or a blown speaker.

verify that you dont have any positive strands coming in contact with negative strands/terminals, the amp case, the speaker frame, or any metal part of the car chassis.

verify that you only have a 2 ohm load connected to the amp. most car speakers are 4 ohm (siginfied by the greek letter "omega" on the back of the spoeaker magnet, or in the speaker specifications), but some are 2 ohm and/or 2 ohm x2 voice coils per speaker. 2x2 ohm coils/speakers would produce a 1 ohm load, which would cause the amp to overload, and go into "protect" mode. to achieve a safe load, you need to use 1x4 ohm speaker, 2x4 ohm speakers or a dual voice coil speaker with 4 ohms per coil x2 voice coils, wired in parallel.

you can also achieve 2 ohms with 2 speakers with 2x2 ohm voice coils apiece (that is, 2 speakers, each with 2 ohm voice coils apiece, 2 speakers with 4 voice coils altogether of 2 ohms apiece) by wiring the two coils per speaker in SERIES, and then wiring the two speakers circuits in PARALLEL. wiring the coils in series means connecting the positive lead of one coil to the amp positive, then connecting the same coils negative to the positive of the second coil, and finally connecting the negative from the second coil back to the amp negative terminal. if you wire both dual voice coil speakers in series, and then connect both series circuits back to the amps positive/engative, than you have the coils in series, and the speakers in parallel- achieving an overall 2 ohm load from 4 total voice coils between 2 speakers.

if you need a better explaination, comment back with your exact speaker combination (brand and model # of speakers + number of speakers), and i will provide a more specific description with your exact speaker set-up in mind.

A better solution would be
1: Get a seperate amp for the sub itself
2: Run 2 speakers on ch 1 and 2 speakers on ch 2. I assume your speakers are 4 ohms, in stereo mode that amp is stable to 2 ohms. The bridge the subwoofer on ch 3 & 4. That will work if you just want to use that amp. If you need more help you can email me @ thefowlerfam09@yahoo.com Hope this helps...

Will i damage the stereo in my 2001 toyota sienna if i replace the stock 8 ohm speakers with 4 ohm speakers? the rear speakers are blown. if i can should i do all four? i happen to have four 4 ohm speakers


You can use the 4 ohm speakers if you don't get carried away and crank the volume all the way up. If you really crank it up there is the chance of doing damage to the stereo amplifier. 8 ohm speakers would of course be better, but if it was me I'd probably try it. No guarentees though!

Impedance must be matched to have a better sound performance. Althought, it has no problem b/w 4 Ohm and 6 Ohm impedance-it still work but the system may get hotter due to impedance mismatching. You can try and see how the sound goes.

Series wiring of a 4 ohm DVC subwoofer will result in an 8 ohm load.
See the following diagram.
The diagram listed has a dual 2 ohm voicecoil, netting 4 ohm, however in your case, the dual 4 ohm sub will net an 8 ohm load.

General ?


they are dual 2 ohm all L7 are 2 voice coil per speaker so it is like 2 speakers not 1 the dual 2 ohm version is so you can use 2 speakers wired in series to get a 2 ohm load 2 ohms + 2 ohms = 4 ohms then parralel the 2 at the amp to cut it in half to get 2 ohms. I have full warranties on mine and i dont really sell alot of them any way I prefer the hifonics they sound better last alot longer and take way more power and put out 3 times as much sound. but i can check it out if you have the info.
