Ok, I know this has just been covered...but please bear with me, I want to KNOw I am right for my specific application...

2-dual VC 4ohm subs CAN be run off of a 2-channel amp that is in BRIDGED 4ohm (4ohm x 1) mode...correct??

I think I am right...please verify before I lose it totally

yes...you wire the subs in series...and then parallel them together [img]graemlins/thumb.gif[/img]

Essentially.

You would series each woofer so it was 8 ohms and then parallel the pair which would be a final 4 ohm load for the amp.

You don't set the amp for an output impedence though (unless it's a Linear Power but that's a different story).

yes, I know, Dukk, I was simply typing unclearly...

thank you kindly, gents

Why do you want to run the amp mono?
When bridged amps typically produce the same amount of power as they would in 2 ohm stereo
(ie 250 x 2 @ 2ohm also produces 500 x 1 @ 4 ohm)
With this in mind, you could run the amp in stereo with the coils running parrallel and each coil would get the same power.

[edit] Also running in stereo means you can have your bass running on independant channels. There's music that has the bass sliding from left to right and back and it sounds really cool on seperate speakers - not too noticible when they are both in your trunk. But its a little thing, A nice thing in my mind. [/edit]
I suggest this because I am not a fan of series applications - the imperfections/ colouring of one coil is automatically shared with all other coils in the same series.

Yeah yeah, now everyone can jump on me because "the colouring that is there is so minute you wouldn't be able to hear it" :rolleyes:

^^^^I like your idea. Not what everyone would say of the top, so kudos for being original. Got to keep some flavour going around here. It's stinking winter time!

It is original alright. I have a question though i realize the human ear recognizes direction of a sound because of the fact that the space between left and right ear is a large part of higher frequency wavelengths. But below 200 hz the human ear cannot identify direction due to the fact that the distance between ears is such a minute amount of the wavelength so how would stereo vs mono be of any advantage. As far as i knew sub bass was almost non directional. Like the reasoning behind 1 subwoofer in dolby digital and the fact that in an mp3 lower frequencies are encoded mono. Does it truly improve sound quality? If so please explain, so i can understand!

Series wiring is THE DEVIL!! But unfortunately it is sometimes a necessary evil. I try to keep any series wiring to a single driver.

Stereo bass is certainly a consideration for some systems. As mentioned though if your woofers are side by side in a box in your trunk it's not going to make a lot of difference.

^Dukk is kin to Series, after all he IS the false god of Audio. [img]redface.gif[/img]

Thanks guys,
I figure I can always try it both ways...

I just wanted to double check that my amp would match my subs, impedance wise
