Hey everybody, i have a wiring situation here i need some help with. I have 2 DVC subs and i need each of them to get about 100w. My amp is a 200w rms x 4 @ 4-ohms, so i need to use on of the channels and wire the 2 subs to recive half of the power. The problem i have is how to wire them up. Because the way i have figured the numbers out, if i wire them i series, i will get a 16 ohm load?! Is that correct? And would this give me 50w per voice coil? Aka 100w per sub? Can some one help me out here? Thanks alot.

what type of sub and amp are we talking

if you wired your subs up like so, and then turn your amp gains down you should be ok, but reply back with model #s | 2 DVC drivers with Voice Coils in Series / Parallel
Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 6 Ohms
Dual-4 Ohm Subwoofer: 4 Ohms
Dual-2 Ohm Subwoofer: 2 Ohms | | | |

you are running two 4 ohm dvc subs off of a 4 channel amp correct? is the amp bridge able.
what are your brand and model numbers?

assuming you have dual 4 ohm coils yea, you would get 16 ohms, but, wire them at 16 ohms to the amp, and ur lucky to get 50 watts total. lol. tell us what kinda equipment you've got man, we can help you out a little more once we know that.

Heh, well equipment is the following (not much to be too proud of, but hey it works. And the only reason im using these subs is because they ar cheap, and i am only using them for a project in school. Amp - Pyramid: 200w RMS x 4 @ 4 ohms
200w RMS x 2 + 400w RMS x 1 (3 channel mode)
400w RMS x 2 @ 4 ohms (bridged) And the subs are cheap little $20 "Roadmaster" subs from walmart. Im using them to get some experience with DVC subs. They just look cool, so its like some cheap Audiobling, but probly sound better... I only plan on using 1 channel, not be bridged. Im thinking now, that i could hook them up like shown in the picture above and end up with 100w per sub?... Thats exactly what they need, they are 100w RMS / 200w peak subs. -------------

well if you take into accoun that the outputs on that amp are probally not anywere near what the company claims, you could just run each sub to a seperate set of bridged channels running the vc in series. or you could run both subs to a single pair of bridged channels and run the subs in a series parallel setup.

Thats actually already takin into affect. They claim 250w rms per channel, i know its not that, so its actually about 200w. Its a "1000w" amp, but really an 800w amp. I don't bother saying it has that much power, i know its lower than what they advertise. So i just compensate whenever I mention the power of the amp.
