Silver Member Username: 420pimp2Post Number: 813 Registered: Jan-06 | I use to know what the difference was a few years back but somehow it has skipped my mind. Please give me a simple explanation on how wireing things to 2ohms 1 ohms or 4ohms is. What is the difference and how does it work. I no you need certain subs at 4ohms or 2ohms to work with certain amps so you dont fry them or somthing. Please explain. |

What that means is, when you wire in parallel, the resistance drops by half. In series, it doubles. Therefore, 4ohm DVC (there's 2 4ohm), wired in parallel will give you 2ohms (pos to pos, and get to neg), in series (pos to neg and use the other ends), it'll give you 8ohms. If you look at an amp's spec of, 400w @4ohms, 600w@2homs and 800w @1ohm, to get the desired power, you will need to match the ohms. One 4ohm DVC sub will give you 8ohms or 2ohms. Two 4ohm DVC subs will give you 16 Ohms, 4ohms, 1ohm configurations. So if your car can't handle 2 subs, then stick to 2ohm DVC sub. That will give you 4ohms and 1ohm. |
