NEED HELP on OHM load

[sciontistbb 10+ year member]

What is the ohm load of three D4 subs wired in parallel/parallel. Or as my friend puts it. All positives and all negatives to the amp. He moved out of state and a coworker is doing his install. They have no DMM and think series/parallel is incorrect even after I've text diagrams.

2.67 ohm load.

This is correct. 2.67 ohms is not correct. Just divide final load of each driver (2 ohms) by the total number of drivers. 2/3 = 0.67.

Got my reference from here:

Rockford Fosgate® - Woofer WiringWizard

edit: just looked at your other link and seems i got the series/parallel ohm load... Sorry for misinformation.

You figured it out already. Your diagram was three D4 subs wired in series for 8 ohms each, then wired in parallel.

My guess is the RF Woofer Wizard doesn't give you diagrams for final ohm loads lower than 1.

OP, make sure your friend's amp can handle an impedance that low.

Your correct it took me a few minutes to find a online guide that have me configs under 1. Ohm

Thanks to all you guys...

You would of thought I was subscribed to my own thread!!! Thanks for the JL diagram. I checked RF, the12volt and kicker with no luck. I figured 0.67 was the correct ohm load but wasn't 100% sure. I had them get a DMM an they were actually reading .65 ohms, the amp is a Brutus 1100.1 bxi model pushing 3 polk audio db's

I got them to re wire those subs at 2.67 ohms (series/parallel). Dealing with this kid installer was a pain in the rear. A real know it all expert, 3 yrs in the business.
