Re: Question about dvc subs and bridging my amp...
This won't be much help.. but.. depends on the amp for 2 ohm stability.. Most times an amp won't run bridged at 2 ohm.. If you have dual 4 ohm coils, you pretty much end up with 2 ohm or 8 ohm.. at 8 ohm you have 1/2 the power you thought you had at 4 ohm (roughly).. just like going from X at 4 to 2 ohm tends to give 2X..

Now that I finally picked up my dual voice channel sub (10w3) I'm totally confused. Before I bought the sub I was clear on the notion of bridging two of the channels on my amp (its 4 x 65w at 4ohms) and how the 2 channels would double in power (so they go from 2x65w at 4ohm to 1 channel @260w at 4ohm). I figured the 260w (or probably less than that depending on the amp efficiancy) would be a good fit for the 10w3.
But now that I have the sub I'm learning how if you wire it in parall the sub goes down to 2 ohms or if you wire in series it goes up to 8 ohms. How does this relate to the amp? If the sub "goes down" to 2 ohms how many watts will the sub see? Is this stable/ok?
That said, you could bridge each coil.. that is, you have 4 channels, right? you can do 2 bridges (to 4 ohm each).. a pair of channels for each.. Now, the tricky bit.. you have to have the exact same signal to each VC or you will blow them.. But, if you have the exact same signal going to all 4 inputs on the amp, you can run a bridged channel to each VC (at 4 ohm).. At least, others have.. or so it seems..
Knowing the amp type/model will probably get you more help.. That's all I can offer from what little I know..
(1) Alpine CDA 7892 HU ($214)
(2) 12" Pioneer Premier 1241DVCs in sealed MDF box (gonna glass them eventually) ($69 each)
->removing.. ->(2) 10" Pioneer Premier 1041DVC's in sealed MDF box (gonna glass them eventually) ($59 each)
(2) Lanzar Vibe248 1200 watt 2 chnl amps ($119 each)
It's bump'n GOOD!
