I had a pioneer 12" IMPP....with a kenwood 300 watt bridged down to one channel....and i opened the trunk yesterday....and there was a clean split from the metal cap...to the foam...no ipact on the sub...b/c there is nothing to hit it...so i don't know what happened.....anyways...it was in a sealed box...and my friend decided after he bought two 12" Audiobahn's dual voice coil....400 rms handling...and is now selling them ( never used ) for $100 a piece...so i will just drop one into the box....
anyways....
i'm not to sure what the diff is between the dual voice coil and single is.....and if i should bridge my amp to one channel....or keep it at two...it will be in a sealed box...i've never really used dual vc before so ....any input would be appreciated....

It depends on what the ohm rating of each coil is on the Audiobahn - lets assume it's 4 ohms per coil:

Basically, wiring the coils in parallel will give you a total 2 ohm load to the amp. I doubt you Kenwood amp can handle a 2 ohm sub - it is probably rated for 4 ohm minimum when bridged.

There are othe options - wire the coils in series - this will add the ohms - for a total of 8. Not the best option either, because your Kenwood amp rated for 300 watts is probably (again) at 4 ohms bridged - you'll only get 150 watts at 8 ohms.

If the Audiobahn has dual 2 ohm coils, or dual 8 ohm coils, you'll be okay. Ifthey are 2 ohms each, wiring in series gives a total of 4 ohms. If they are 8 ohms each, wiring in parallel gives 4 ohms, also.

You need more info on this sub first. Find out the specs, and reply - this might not be the sub for you.

BTW - I made the same mistake, buying a DVC JBL sub - I basically couldn't use it. Luckily, I was able to sell it on eBay, and actually MADE money on it. I didn't know what the hell a DVC sub was either. Live and learn. Get the specs for the Audiobahn and post them.

Been reading alot about Pioneer subs just cracking on the cone. Sheesh!

Also, don't just hook up one coil of a DVC sub. I don't think your amp is the best for a DVC sub.

No doubt that you amp wouldn't handle a 2 ohm load...

when i bridge it down to one channel....it's running 2 ohms...all i have to do is run it paralell to the voice coils ( the sub must run 4 ohms total ) so that's 2 ohms each side ( total 4 ohms )....

it worked when i tried it...but the sub is VERY power hungry.....so when i turn it up...it fades at parts when there is a lot of bass...

so i turned off the loud setting on my deck..and the low end down...and it sounds nice now...till i find a bigger amp...

.... i'd like to find another 300 watt kenwood....bridge both down .....run the same signal to each amp...and run 2 ohms off each amp.....the placement in the trunk would be cool...

Oh for sure man, any dual VC is power hungry. I had 2x12" Soundstream USA's running off a Reference 500sx. When I first installed it I cheaped out and ran 8awg wire to the amp. When I cranked it up for the first time it melted the coating right off the power wire.

So then i ran 1/0awg.... No more problems

i've got 10 gauge down now...but when i get more power...i'll get 40 gauge from my buddy..he an electrician....so i get it for nothing...:P

hihoslva

40 gauge? That'd be a little thin don't you think?

Just kidding - I'm sure you meant 4 gauge.

jgoertzen

wow...i gotta start reading what i type before i send it...yeah ...i meant 4 gauge....
