need help on wiring

[K&c Customs 10+ year member]

ok i have 2 15 in L5's dual 4 ohm voice coils.. i want them to run on a 1 ohm load...

it shows they are both on a 2.5 load... would it nbeing on 1 ohm make a difference?

need help

i hooked them up to a 4ohm load and i put the ohm meter to it today and it showed 2.5... is that right? will i tell a differnece in the performance on 1 ohm?

anybody know

your questions dont make sense

i reread it a couple times

your dmm is probly reading 2.5 ohms because the coils are not actually dual 2 ohm dcr or your dmm is cheap or maybe u have bad connections where u have the subs wired to 2 ohms

the subs are dual 4ohms and there wired to 4ohms. Will i tell a difference if i hook them up to one ohm? Also the ohm test was done at a stereo shop

yes u will see a large gain going from 4 ohms to 1 ohm as you will be more than doubling power

so would you say it was running on 4ohms or 2.5 ohms with the ohm meter saying 2.5...also i have 18guage speaker wire on it and im about to put 8gauge wire on it would that make a big difference also?

the nominal impedance of a speaker is not the same as its DC resistance.

impedance is frequency dependant and is an AC measurement.

when you measure a speaker with a multimeter, you are measuring its DC resistance, which will be lower than the drivers given nominal impedance.

in reality, a "4ohm" speaker, may have an impedance anywhere from 2 ohms to 20 ohms, depending on the driver itself, the frequency, aswell as the enclosure its in.

if you were to wire all 4 coils in parallel, to give a theoretical 1 ohm load, in reality, you'd have a 0.625 ohm resistance, which will more than likely be present to the amplifier at certain frequencies, and may cause it to go into protect.

you'll have to try it and see.

ok 1 how are u wiring to 2.5 ohms? each sub is 2.5 and then u parallel themtogether to 1.25 and you may see a slight gain on that wire change

I just answered all your questions d!ckhead, what more do you want us to say?

they are wired up like the rockford fosgate thing says.. to 4 ohms...

changing speaker wire from 18 gauge to 8 gauge make a difference?
