Just wondering if you can run a 4ch amp to a single dvc dub by bridging the amp to 2ch and connecting each channel to a voice coil.

I'm thinking of running a 50x4 Orion Cobalt on a dual 4ohm L7

 

What size L7 is it? Don't they usually like a fair bit of power to work their best? Just curious....

 

level matching isn't enough, make sure that you have a mono signal going into the amp aswell, or your DVC wont last very long

 

its a 12" in a ported box. The amp will put out 150-200W to each voice coil. I'm just adding it to the factory system in my work truck so I don't need alot of bass

 

ok, thats exactly my problem with that setup. The right and left stereo channels will have a difference in signal between the two. For instance, if the song, track, advertisement, whatever, sends an 70 Hz signal to the left channel, and not the right one, (which happens more often than not) then only the left channel on the amp, will be active, not the right, meaning, that only one voice coil is working. And scince the V.C.'s are interwoven, this can cause heat, wear, and basically, total destruction of your coils. Just imagine now if the left channel played a 74 Hz note, and the right played a 70 Hz note, it may not mean immediate activation of the magic smoke, but it cant be good for your sub, and a good sub is an awful thing to waste. Now a good way to stop this problem, is an easy answer. Probobly the best and easiest way is to purchase either a three channel ACTIVE crossover network, or an ACTIVE sub crossover, with a high level input. This way you can run the sub off the rear channels, and have a guaranteed mono, and crossover at whatever Freq. you want. Just split the RCA's after the crossover. We have a nice one by power Accoustic.
