hey everyone! - i'm working on custom making a fiberglass box for my C5 that utilizes my trunk drop down for a 15" Audiobahn DVC and i this will be my 1st inverted sub install and i wasn't sure about the phasing if i need to swap the pos/neg to make the sub hit in reverse since the sub is mount in reverse?

Any help is appreciated

i would swap phase just to keep the phase same throughout ur system

yeah i agree, i've got an old school Infinity Kappa 202a 600x1 amp - i've never actually swapped the phase on a sub before, is it as simple as taking the pos/neg from amp and going to the opposite terminals on sub? since this sub is a DVC (dual voice coil) how do i wire that now that its swapped?

pentavolvo

what i would do is wire everything like normal ur VC's etc. Then at the amp swap positive and negative where you hook the sub up

yep i understand, i'll give it a shot once the box stuff is done and wiring is done

The biggest item of concern is having the dual voice coil - make sure they are wired in the same manner - otherwise they'll be cancelling each other out - pentavolvo suggestion is the easy way to do this.

As for reversing the polarity - technically you should so that it matches the other speakers. But the reality for subs is that you can go either way - try both and see which sounds better. Some people with their setups can notice a difference - some can't.

Also, some processors have this feature build in - usually under the 'phase' option - it can either be 0 degrees or 180 degrees - if you have a process like this - you can control it from here instead.

it doesnt really matter as long as you only have one sub. i would reverse the polarity though. i had a box with two inverted subs and i kept messing with the polarity...i did notice a minor difference.

Yes, reverse the phase.
