4 ohm vs 4 ohm mono wiring help?

[Bass911 10+ year member]

I have a 5 channel amp. The fifth channel is rated 250@4 ohms and 500@ 4 ohms mono. How does the amp know the difference between the two? I'm guessing you need 2 4 ohm dvcs to get the mono load and just one sub to get the regular 4 ohm load? I'm trying to decide between 1 Re srx12d4 ported or 2 rtpro10d4 sealed. I'm not looking for the loudest, just want to add a little bass to my mothers car. I don't want to get the 2 dvcs if the amp is only going to put out 250 watts. I already know how to wire it for the 4 ohm mono load, but I was just wondering how the amp knew the difference between the two?

What amp do you have.

Audiobahn a5005j

The amp will see whatever load you wire to it... To get a single 4 ohm load you need either: a single sub with single 4 ohm VC, a single sub with dual 2 ohm voice coils (wired in series), or 2 subs with dual 4 ohm voice coils wired VC's series / subs together parallel, or VC's parallel / Subs together series - either way will give you a single 4 ohm load...

that's what I figured. I was always told that you needed 2 channels bridged in order to get a 4 ohm mono load. Maybe it was the usual Audiobahn misprint?

Well if it's a 2ch amp, then yeah... if you're only running a single 4 ohm load then the 2 ch would be bridged //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
