4ohm and 6 ohm

[99RangerBoss]

Hey would you guys know if you could run a 6ohm sub off a 4 ohm amp. Would you know the limitations of an amp like whats the most and the smallest about of impedance you can run?

You can have a higher impedance no problem, up to about 16Ohms you just have a lot less power going to it, but you can't run under the lowest impedance listed.

so would it be possible if i ran my two 6 ohm 8 inch subs in my truck with my amp no problem?

How many channels does your amp have? Because if you have only 1, you could do 12 or 3 Ohms, a good name brand amp should be able to handle a 3Ohm load.

We need to know how many channels your amp is, if it's bridgeable, how many voice coils are on your subs and what the ratings are on your amps and sub and at what ohms.
If you have 2 subs each with a single 6 ohm voice coil, you will be able to get to either a 12 or a 3 ohm rating on a single channel amp. If you have 2 channels you will also be able to get 6 ohms. What that basically means is that is how much resistance your amp has to go through to power the subs. The higher the number the greater resistance.
Your amp has ratings at different ohms. Most amps are stable as low as 2 ohms, while the competition ones can go down to 1 or even lower. An amp that is rated for say 400 watts at 4 ohms should be rated at 800 watts at 2 ohms.
Here is a link to some diagrams that may help you understand it.
