Question bout subs
- Thread starter Groza187

the choice of 2 or 4 ohm is determined by the amplifier you are going to use. Some amps produce there best power at 4 ohms, others at 2. Thus amps and subs must be selected to match.
Manufacturers give you the option of 2 or 4 ohms so that you have the ability to use numerous amps and different numbers of subs.

hey I have two Kicker L7's 12 inch, There 4 ohms. I have a Fosgate 600@4 crossed over. Have no clue if this is a good combo or how to tune it right. So I cant really help. But if any one knows what settings i should have feel free to tell me. Also since they are dual voice coils i know you can wire the speaker in parallel or series circuit, But i also dont know which to do. Help me too!?!?!?!?
What is the model number of your Rockford Amplifier and your Subs.
Hmmm the only numberI know is L7 for the solobarics and fosgate 600@4. What other numbers are you saying?

The minimum power you should be using for those subs is 300 watts rms apiece from a good amp no BS Jensen or Sony.
The kicker kx600.1 would be my reccomendation for 2 2ohm, dvd L5 10's. You wire the DVCs of each sub in seires to get 4 ohms per sub then parallel the subs together to get a total 2 ohm load which is the best to run the kicker amp at.

Here ya go!
In this diagram you wire 2 sets of 2 subs in series, one subs + to the other subs -, then you parallel the sets.
When you series the subs each set becomes an 8 ohm overall load and when you parallel the sets you get a 4 ohm total load.
2 ohms is not possible.
Every time you series 2 subs of the same impedance you get the impedance of 1 sub times 2. SO if you have 2 4 ohm subs, (4x2 = 8ohms)
Every time you parallel 2 subs of the same impedance you get the impedance of 1 sub divided by 2. SO if you have 2 4 ohm subs, (4/2 = 2ohms)

Here you go.
When you series the coils, the blue lines, it is like a single 4 ohm sub, when you parallel the subs, red and black line you get a total 4 ohm load.
If you think this is bad try wiring my 4, 2 ohm DVC JL Audio 8W3's.
nothing like 8 voice coils to wire.
What do you guys think of this?
