Are there any problems with wiring a 4 ohm speaker and a 6 ohm speaker together (I assume this becomes a 3 ohm load)???

i dont think your suppose to mix voice coils

depends how u wire it...

parallel: (1/Req)= (1/R1) + (1/R2) = (1/4) + (1/6)
Req= 2.4ohms
Series: Req = R1 + R2 = 4 + 6
Req= 10ohms

im going with parallel ... but the real question is there anything wrong with wiring these 2 different speakers together?

well it kinds depends. i wouldnt recommend it for regular speakers, but it should be fine for subs. you just need to understand how the power is detributed and how much they can handle

Im bringin back old general physics knowledge here, so be advised, there may be mistakes ha ha...

P=(V^2/R)

now the Voltage across all resistors in a PARALLEL circuit (not series) is the same. So the variable is the Resistance. so you got a 4ohm and 6ohm resistor...

P1= (V^2/4ohm)
P2= (V^2/6ohm)

compare to ratings, if they dont exceed RMS power handling, you should be set

- That's an old myth. Total ohm load will be less than 4 ohms. The 4 - ohm speaker will get a little more power than the other. other than that, it will work just fine.

the power will not be distributed evenly, even if they handle the same power load current takes the path of least resistence so your 4 ohm speaker would get more, in return would probably have one speaker drown out the other. Wouldnt be recomended, i say seperate the subs. what does everyone else say?

You can do it, but it won't sound good.

They arent subs ... Eclipse 6.5" coaxials (fronts @ 4 ohm) and these random 6.5" mid-bass/woofers (back @ 6 ohm).

I'll see how it sounds. Its not a permanent thing so its not a big deal if sound is perfect. I just want to get the speakers louder and clearer.

Back speakers are retarded and wiring them that way would be even worse. If you want it to sound "clearer" that isn't going to help at all.

you would lose all ability to fade your music front or rear.. just to give you the heads up.

why would ou wire you fronts and backs together anyway, run fronts of HU and then backs of a little 200 w amp and ou wont even have to worry about 4 and 6 ohm. just dont wire them together.

Did you mean the other way around? :)

Im not worried about fading right now (I probably will when the speakers are amped though, lol). The only reason I want the backs amped with the fronts is because of the mid-bass driver. It doesn't get loud enough off HU power as it sits now. The eclipse's really have no low end umph (I know they're not really made for that purpose), so i wanted those to act more like high frequency mid-bass with a side of tweet. Either way, I'll probably wire the speakers both ways to see what I like better.

yeah i did, sorry my bad. ^^^
