Title: Sub Help..
Post by: ju571n on 07 October 2010, 19:21

Right then. Im looking at getting a new system for the motor, ive had many a system and always built and wired them myself and never had a pronlem so far but never a dual voice coil sub and to be quite honest, its confusing the s..t out of me!

So im looking at getting a Dual 4ohm sub, could i wire it up 2ohm to the amp. Or will it double in resistance to 8ohms? Or if i wire it parrelel will it stay 4 ohms?

I ask because if its gonna be wank and cant wire it up at 2ohms then ill look at another sub...

Any light will be apriciated.

A dual 4 Ohm voice coil sub can be wired to give a 2 Ohm load at the amp.

Parellel will show 2ohm.

Series will show 8ohm.
