Question about DVC subs ...

[s52e368]

i have a premeir (sp) 12" DVC in a large ported box. with a good sized amp.

(this may sound silly)
currently the box is setup with one cup, so the sub is "bridged" so to speak.
im going to add the second cup this weekend to set the sub up correctly..

now my question is: when connecting both cups to the amp do i go to different sub channels ? the same channel for both ? or do i have to buy a second amp ?

Kind of depends on what ohm rating your shooting for and how you're wiring it. Series, parallel.

well im not sure but i found these...







i thought you could run either coil connection to seperate cups on the box ?

If you are gonna stay with one sub, look at it this way: You have a "Dual Impedance" subwoofer. It can be either 8Ω or 2Ω, NO OTHER CHOICES ARE POSSIBLE. This, right here, is what I hate about the industry.

There are no amps on the market worth a shit that prefer to run on a 2Ω load.

There are no amps on the market that like a 8Ω load.

So, here are your choices: a 2 channel amp on a 8Ω load, making half the power you are supposed to, or on a 2Ω load, with excess heat, excess distortion, and letting out the excess smoke.

Understand that the load on a 2 channel amp wired in "Bridged Mode" is shared between the 2 channels, thus a 4Ω load is 2Ω per channel. 2Ω is 1Ω per channel...or acess to the smoke storage module on most 2 channel amps.

Teh goal on virtually every 2 channel or 4 channel amp made in recent years is 2Ω per channel so either a 2Ω (X2)load wired in stereo OR a 4Ω load wired "Bridged" make EXACTLY the same load to the amp, thus make the same power...no difference whatsoever!

Also, most decent 1 channel amps today make their best power on a 1Ω load, so you can run it at half of its intended load, making half of the power you paid for.

So, now that I have explained all of this crap, here are your choices:

1. Add a second sub. 2) 2Ω subs can give you either 1Ω (for a 1 channel amp) or 4Ω (for a 2 channel amp, in bridged mode).

2. Find a 1 channel amp that likes a 2 ohm load. Memphis MClass 500 watt is one that comes to mind, the goofy Sony"P5" series (which do make some rockin'ass power) or the ultra POS "Bolt" series from Lightning, which make some decent power, but need their add on fan to not overheat and shut down on their intended load! With the fan they are some butt-rockin' little amps though.

3. This one is tough, because actual set up needs to be perfect, or you will have a woofer roast on your hands. You can run 2 small 2 channel amps, each one running bridged. The deal is that ANY variance in voltage between channels is woofer smoke in just a few minuites.

Matching voltage between the 2 amps is pretty easy if you can operate a screwdriver. And a DVM. And a radio...

4. A 4Ω woofer

5. Do it wrong.

my current amp is
Rockford Fosgate Punch P3001

You just happen to have the correct amp for your application.

You should have your two coils wired in paralell, to make a 2Ω load, as in the second example you showed.

No need for a second terminal cup.
