Wiring each voice coil separately...

[hoxie08 5,000+ posts]

Okay, so I sold a buddy of mine my RE SE 12. D4. First thing he says when he gets it is, "yeah I'll just wire each voice coil up to a different channel on my amp since its not 2 ohm stable in mono, that way I still get more power out of the amp". I personally have never heard of doing it this way.... seems to me that if something is trying to push the left and right channels differently they would cause interference with each other.

Any input?

I guess a simple Yes or No would also be a fitting answer for this lol.

anyone?

i dont wanna have to bishslap a retard friend cause they blew a practically new sub .. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Hmmm.

Well, to answer your question, yes he can. All that needs to be done is sum the left and right channels to mono. That way there is no difference in the signals going to either coil. But, wiring up the coils seperate to each channel will render the same over all impedance as would bridging the amp. Remember, bridging an amplifier merely means combining the output of both channels. 2ohms stereo is the same as 4ohms mono bridged.

Ah, so basically it would make no difference?

if you ever have amp failure the sub is screwed just incase ya didnt know

Correct.

Running the D4 sub with each coil on a single channel of a stereo amp would have the same result power wise as running the sub with the coils wired in series (8 ohms) to the same amp bridged. If those were my options, I'd go with the 8 ohms bridged. Makes completely sure that the coils are getting the same signal. Sending them a different signal won't hurt the subs but it will cause a bit of distortion.

How do you figure? You can run a DVC sub on a single coil. It just changes the T/S parameters and the power handling.

My thoughts exactly about the 8 ohms bridged... He's not gunna benefit any power wise by running each channel to a coil... Just wire in series and bridge it at the amp to yield an 8 ohm load...

i have a BTL and 2 pdx 1.1000 that arent bridgeable. any idea on how i would tune this? or make sure that the sub is getting the same output?

Set each amp with a DMM to produce the same voltage. Done.

Not different amps, just channels... wouldn't benefit by running it 2 channel compared to 8 ohm bridged (mono)
