Wiring help with dual 1 ohm voice coil sub to 4 ohms

[gymdiver426 10+ year member]

Hey guys I have a sub that's a dual 1 ohm voice coil and also have a 2 channel amp that's only stable at 4 ohms bridged. I would like to know how to wire the dual 1 ohm voice coil sub to 4 ohms if that is even possible. If you could explain that to me or show me a diagram it would really help out.

Nope u can only wire that sub to .5 or 2 ohms ....go to Car Alarm, Car Stereo, Mobile Video, and Cruise Control Info for Installers. and learn about series and paralel wiring

not possible.. You would either get .5 ohm or 2 ohm.. You could get a roll of 14-16 gauge speaker wire that is like 50 feet long rolled on a spool to add resistance and raise the impedance to 4 ohm. Might need to be longer or shorter of a spool of wire. Just get a dmm and measure the ohms on the wire from the end of the spool after you connect the wire from the speaker to the spool.

Start ith 50' and if the resistance is above 4 ohm then shorten the spool, if its lower then lengthen the spool. Only way i know that works

Or u could jus do research and buy the.right sub to begin with ..or a amp that will run at 2 or .5 which isnt hard to find

Yea he could do that, but if he is stuck with what he has this is a possible solution! Improvise!

I would sell the amp and get one that will work or sell the sub before i rigged up a spool of wire lol

I so wanna try this for sh*ts and giggles!!

its the old school way homie! its just a "coil" that adds resistance and its a lot cheaper than a new amp //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thanks guys, sub is an old soundstream T4 10" and I might end up just getting a different amp that will handle 2 ohms, thanks for the help all!
