Part 1: 1ohm amp load to two dvc 4ohm subs how is wattage affected? Part 2: Would I use 1ohm or 4 ohms when using ohms law to set my gain?

[QUOTE="Lasherž, post: 8706003, member: 679555"] That's the most well-organized giant mass of text I've seen on this site so far, kudos lol. Each coil is 4 ohm still, but when they're all wired to parallel your amp sees 1 ohm. It's easier to think of it from your amp's perspective not your subs. Your 800W 1 ohm stable amp is very well matched for a parallel load on two DVC 4 ohm subs so you're just fine doing that. It will effectively be 200w@4 ohm to each coil if you must think about it from the subs' perspectives. The amp you have is exactly what you want, no need to swap unless you don't like how it sounds. You go by the amp load for that equation, you're overcomplicating it by thinking of the voice coils separately when they're connected to the same terminals on the amp. So you would use 1 ohm. The 14.4v thing is the battery voltage of your car. What they're saying is that when the car is running and the alternator is keeping it at a healthy 14.4v it will deliver 800w RMS. Current kills amps, so lower voltage on the battery will lower the power handling of it proportionately from 14.4v. I wouldn't worry about it beyond just not running the amplifier at full tilt with the car off. That's not good for your battery anyways. [/QUOTE]
