how to wire this!
Thursday, April 20, 2006 12:28 PM
ok ive looked at that one site were it tells you how to wire subs up but it doesn't show how to wire them up to two channels. it is a 4ohm sub that i want to hook it up to two channels .... can some one PLEASE help me?

Single voice coil, wire the positive side to the positive terminal on the left channel, and the negative side to the negative terminal on the right channel. That's the most common. If it's a dual voice coil, wire one coil to the left channel, and the other coil to the right channel.

actually, dvc, i woyld wire them to the proper ohms then bridge them

ok sorry i wasn't very clear in the first post and i will make it more clear. I have a 4 channel amp right now. I have the front hooked up to my component set, and i have no rear speakers so i was going to hook the Doil voice coils up to the amp until i get the next amp. i dont want to blow this sub up so how would i go about wiring it... diagrams are always helpful

dual 4 ohm voice coils wired in parallel for a 2 ohm load



dual 4 ohm voice coils wired in series for an 8 ohm load

Ok sorry to piss every one off but here is whats all going on so far in my trunk!

i have a Avionixx 440.4 amp right now it is a 4 channel amp (all i haev right now will be getting upgraded as soon as i get the money for it) here are the specs on it ...
MAX Power @ 4ohm 2x440 Watts Bridged
RMS Power @ 4ohm, <0.05% THD 4x85
RMS Power @ Bridged 4 ohm <0.5% THD 2x220
RMS Power @ 2 ohm, <0.5% THD 4x110
Power Bandwidth (Rated Power -1dB) 15Hz - 30kHz
Frequency Response (+0/-3dB) 5Hz - 70kHz
"A" Weighted Signal to Niose Ratio >-90dBA
Channel Seperation >60dBA

The sub is a SE12 witch is dual 4ohm

I have a in/out put converter connected from behind the headunit to the amp. The rear RCA cables go from the converter to the amp as do the front.

I know that the amp is NOT 2 ohm stable ... 8ohm i dont know eather.

I had one coil hooked up the one channel each and my sub does not work to this day and im ordering a new sub.

I know that amp will underpower the sub if i can get it hooked up right but again i plan on getting a hifonics sub that will fully power it and i will be abel to power a second one at the same time. the amp will be a mono block so i wont haev to worry about the pita deal im having now.

So the actual question .... Will i be able to hook up this sub to this amp or will i have to get the new amp to make my sub work safely?

Dude, you seriously need to proof read ur posts...ur gettin a hifonics sub to power ur sub? i know u mean amp but stil...

u really should power speaker and a sub of the same amp, iirc

If you Bridged the four channels to make 2, you could wire it to your sub, 1(bridged) channel per coil.

i think he said he is powering his fronts with the amp as well, so no dice on this unless the amp can run tri mode (2 channels on an amp that can run bridged but also run them stereo to their seperate components).

my DVC is wired to 2 channels on my amp, the other 2 channels powering the fronts.

this is my best setup as my amp is not bridgeable. you could bridge the both channels and power your sub with each of the bridged outputs, then power your fronts IF YOUR AMP CAN RUN TRI-MODE. if not, the setup i said above how i run mine is your best bet.

if you are amping your fronts and your sub, but the sub wont work and the fronts do, try flipping them around. what i mean is if channel 1 and 2 are for your sub and 3 and 4 are for your fronts, but your sub isnt working, try running your sub off of 3 and 4. if the sub works when you run it on the other 2 channels, then your amp may be shot.

check your wiring, if you have 2 sets of RCA's from the head unit back to the amp and your sub wont work, the rca could have cmome out of the back of the head unit or eq or what ever you are using.



Injection is nice but id rather be BLOWN!

ok i know my amp is not shot! i have my front component set running on them right now! I am getting a enw sub because i had a RE12 sub and it fried the voice coils are shot!

I am upgrading to a SE12 sub... i have no clue if the sub will do the same thing as what happened to the oher one. i know the specs for the SE12 is a 600 RMS and 1200 total watts and my amp only puts out 2 x 220.

i was talking with chris h and he said that i could hook the sub up to a 2 ohm load but my amp will not do a 2 ohm load. the amp will fry.

So i dont think there is away to make the sub work until i get the new amp. unless im wrong then thats goign to be the route. I had this all planed out that i would order the sub hook it up to the amp until i had the new amp ready then i would switch it to the other amp after i got it wired up.

The SE12 is a dual voice coil, 4ohm per coil I believe.

with a 4-channel amp, the easiest way to wire it would be to bridge two sets of channels.

Now your 4chan amp is a 2chan amp, each channel sending handling a load of 4ohms.

Hook one bridged channel to the POS and NEG of one coil, and the other channel to the other coil.

There are other ways, but then impedance starts getting messy. The sub only handles 200WRMS anyway, so your amp can more than handle it.

BTW, your amp puts out a PEAK power of 880, and the sub can only handle a peak of 450. This is probably why you blew the last one, but I can't for the life of me remember how to correct it. :S

ok i got that idea down but the problem is i have my component set hooked up to the front channels ... i only have the rear channels to work with!!



Re: how to wire this!

you have 2 set's of rca's goin to the amp right????

hook the frount 2 up to the comp. set you have and hook the rear left ch to one coil and the rear right to the other coil. thats the only way your goin to do it unless you run it at 2 or 8 ohm's.

if you tryed the and it don't work make sure you have the rear cross over set to lowpass and set it around 80hz's. also you can blow the rear ch of the amp and the frount still work so you might want to hook the comp set up to the rear just to make sure..



Re: how to wire this!
Saturday, April 22, 2006 12:05 PM
the rear still works. yes i have two rca cables going from the input/output converter. so i can hook the sub up with one channel per coil? will the sub be safe or will i wreck it?

He wasn't running it off all 4 channels...the peak power is all 4 combined i believe, 2 channels bridged on his amp is a peak of 440, so he was puttin that into the sub, not 880...

with a 4 channel amp, it recieves a L and R from each RCA wire.

so since you have 2 channels to power the sub, hook each left and right from each line level output to your sub voice coil....

example

CHANNELS
1-2-|-3-4

1 and 2 are powering the f components.
3 and 4 the sub,

__RCA___ CH3:::::::::::::: L and R :::::::::: Coil 1 + and -

__RCA___CH4::::::::::::::: L and R ::::::::::: Coil2 + and -

thats probably the best way to set yours up since it isnt 2 ohm stable when bridged.

ok so i could wire each channel up to each voice coil.

now the question is will i be safe? im not going to hook this 190 sub up and blow it before i have a chance to get the right amp for it. im fine with just waiting until i get the right amp if we cant deside on if its a save way to hook it up ot not.



Re: how to wire this!
Saturday, April 22, 2006 7:21 PM
how would you blow the sub???? the olny way your blow the sub is if your amps clippin really bad and if its in a ported box you should be able to smell the sub before you blow it.

oh and i had 2500 watt's goin to a single se, if your smart they can take the power




Re: how to wire this!

^ Agreed. You're not likely to blow the sub on power alone unless you're running massive amounts of power that causes the coil to separate or overheat or otherwise do bad things. Clipping the signal, on the other hand, is a whole other story.
