2 amps, one sub?

Just wondering if it is possible to run 2 amps, one to each voicecoil, to a single sub???

If so, is there anything special I should do if I was considering this?

Thanks

You can do this, but you have to be careful... It's much easier to use a pair of strappable amps when dealing with a single sub, but if yours are not strappable, you'll have to gain match them very carefully. Get a good digital multimeter and take turns adjusting the gain on each of the amps until they give as close a reading to each other as possible (in AC volts).

Sorry, yes, same amps. They aren't strappable though....

Just a little help with the multimeter thing... I'm fairly handy with the whole audio thing, however I've never played with the multimeters....

You just touch the end to the (+) wire and measure voltage???

Thanks!!! Especially for the quick help...

Put the + probe of the meter to the + speaker terminal on the amp, and the - prove to the - speaker terminal

Here's a tutorial on the JL site:JL Audio

And this is a calculator you'll need in order to get the right output voltage on your amps:

You betcha, I'm pretty sure that's the way to do it, but if I'm wrong somebody's bound to correct me.

When you input #'s into that calculator do you use peak watts or RMS watts?

Go with RMS... peak numbers are for the birds... the retarded ones. It's best to use a true RMS multi as well
