Tips on setting my system up?

[NexDeus 10+ year member]

Hey all!

I recently snagged up a audiobahn a8000V (Audiobahn A8000V Mono subwoofer amplifier 400 watts RMS x 1 at Crutchfield.com) to go with my Rockford P2D415 (http://wwv.crutchfield.com/p_575P2D415/Rockford-Fosgate-P2D415.html). Im slightly confused at the DVC aspect here with a mono block. I have the sub wired at 2ohm. Is it 250w rms total or per coil? In other words would I want to set my amp for 250 watts or 500 watts? Sorry if I'm not proposing my question correctly. It's late

thatamp rated at 800 watts rms at 2 ohms your sub or subs are what determine your final ohm and how you have them wred. if you have the sub wired at 2 ohms your fne just turn the amp down a little bit or you can run it at 4 ohms

The amp is mono, and I have a 4ohm DVC sub, I couldnt get that to 4 ohm at the amplifier could I? What I'm trying to figure out is if the 250w rms of my sub is total or per coil.

You can't use this method unless you are 100% sure the amp does rated power. In this case you can't be sure.

Per coil. 500 total.

Hey NoLoud, thanks for the reply here. So I would want 500 watts from my amp, or 31.62 volts? I read somewhere that whether it's DVC or SVC the rated wattage of the speaker doesnt change, which is why I'm confused. Could you provide some documentation that explicitly explains the difference in wattage between a single and dual voice coil just so I can learn how exactly this works, or explain it to me? Does that change if Im running off a mono amp, since I cant control each coil's wattage directly since Im at 2 ohm?

*Edit* I just read on manufacturer's documentation "125w per coil" So that question is answered I guess lol

When a DVC is connected it basically becomes one coil. Shouldn't be confusing at all TBH

The reason it's not confusing to you but somewhat confusing to me is because you've learned these things, I'm still new to them. No reason to be condescending.

Not giving you a hard time but this is very basic info. I wouldn't set the amp higher than 400 watts also. Use a -5db tone to help out with dynamics.

Essentially, you are connecting the dual coils in order to make one coil to power the speaker that is transferred into both coils. For dual voice coil, it just helps diversity in wiring just as a dual 2 can be wired to 1 ohm or 4 ohms with either series or parallel wiring. Parallel = lower ohm load, series = higher ohm load. A single 2 can only be wired to 2 ohms. If you have a dvc 4 ohm sub and your amp does its rms at 2 ohms, wire it in parallel the way that NoLoud4u showed.

your amplifier is 2 ohm stable, wire your DVC sub parallel straight to the amp and the amp will see a 2 ohm load. If your sub is rated for 250 watts then its rated for 250 watts then its 250 watts of power handling total. Dont over complicate things, its a lot simpler then you think.
