Question 4 Ohm VS 2 Ohm

Hello everyone I just got a couple quick questions about wiring options.

1) What is the difference between 4 Ohm and 2 Ohm.

2) Does one sound better than the other?

3) Which one should i go with?

Thanks again for the help cheers!

4 ohm. 2 ohm. it is the impedance (a fancy word for resistance that also included inductance and changes with frequency) that the speaker has and what the amp sees. There is a debate as to whether there is any audible difference. Some say that it is easier for an amp to drive 4 ohms. However modern amps are designed to handle 2 or even 1 ohm

It is not a matter of what is better but what you need for your amp. If you will have only 1 sub then you can pic 2 ohms to maximize the output from your amp. If you want 2 subs then teh best may be to get 2 4ohms subs and put them in parallel to make the amp see 2 ohms.

there is a lot of good info on the various car audio sites. just google it and do your homework.

I think what we would all like to know OP is what you have heard about 4ohm vs 2ohm and which you think would be better.

Basically good info, but it's not exactly complete.

Personally I don't see much of a difference audibly, I look at it as being able to match your subs to your amp. If you wire in series (+ on amp to + of sub1, -of sub 1 to + of sub2, -of sub 2 to-of amp
) you will double the value. If you wire in parallel (all + together, all- together) you will halve the value.

If you take a minute and search for rockford fosgate's wiring wizard, it will show pretty pictures for the concepts I described.
