changing ohm load on subs
 

hey all

something I've wondered about for awhile.....say I had 2 dual 4ohm subs, wired at 4 ohms together and run them like that for 6 months. Then I decide to get a new amp and want to run them at 1 ohm until I can afford to get a second amp, at which time I would be switching the subs to 2 ohm load on their own amp.

will this effect the life span of my subs???

reason being. I'm looking at getting a new amp/s. My subs are dual 4ohm, 750RMS. Currently running at 4 ohms.

The amp I'm looking at is 1500RMS at 1 ohm. 750 at 2 ohm. this would be perfect for me. I could use just the one amp, but, I don't really want to run my subs at 1 ohm. So, I was thinking that I could run my subs at 1 ohm until I can afford to buy the second amp, and switch the subs to 2 ohms.

I would accually prefer to run the subs at 4 ohms, but, I don't think I'll find an amp the pushes 1500 rms at 4 ohms without selling a kidney.

what do you all think? subs will be fine.....or will it shorten their life span?

power is power is power. you'll be fine ;)

no problem i think u will like 2 amps on 2 subs

Dude, you have confused me here. First you have 2 single 4 ohm subs, that means that if they are wired in stereo to a 2 channel amp, you have two 4 ohm subs. They can be wired in series to 8 ohm on a 2 channel amp bridged or a mono amp (but a total waste of power), or wired in parallel to a mono amp that is stable to 2 ohm. These subs cannot run at 1 ohm, no matter what way you slice it.

Now the subs have magically morphed into dvc 4 ohm subs running at 4 ohm which is a series parallel circuit only. No issues running them at 1 ohm or 4 ohm or even a higher load on a mono amp. Maybe I'm just tired after playing with peoples stereos all day but I think I am seeing things correct here.

Run the subs at 1 ohm and be done with it. Will you hear a difference? With that amount of power be it with one amp or two, I highly highly doubt it.

ya if they are 2 dual 4 ohm subs then u can run at 1,4 or 16 if u get bored haha. i dont see why you would buy a second amp when running at 1 ohm they will get approx 750 each teh same as having two of the same amps...:dunno: the difference between teh 2 wold be minimal.

o ya, my amp runs 1600rms bridged at 4 ohm hahaha

Ya dont waste your money with a second amp. It will run fine. If those are DVC sub and have 4 ohm coils then wire it all up for 1 ohm mono and if the amp is spec'd out at 1 ohm mono. Everything should run smooth. You will not gain anything by going to two amps. Except the cool truck full of amps syndrom. :) Both and amp and the subs are designed to do exactly this. Good luck have fun.

thanks all...by the way...I fixed my error....yes, the subs are dual 4 ohm. Sorry for the confusion.
