SwaggerWagon Posted February 28, 2011 Report Share Posted February 28, 2011 I have finally designed a box using Torres' calc (awesome tool btw) and just ordered my second amp this weekend. I'm ordering 2 DC level 3 12s Friday as well. My questions are: should the enclosure for these subs be one or two chambers? I dont want to start cutting and then realize the box im building will sound like crap. The reason I ask is because the wattage from the amps most likely will not be identical. The current amp I have (RF P500-1bd) puts out just over 700 watts @ 1 ohm according to the birthsheet. But I'm sure the second amp may not be identical. How do I compensate for this difference? The box is going to be slot ported tuned to 32-33 hz either way. I also have a self-ranging DMM if that can be of any use. Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted February 28, 2011 Report Share Posted February 28, 2011 What is the other amp?

SwaggerWagon Posted February 28, 2011 Author Report Share Posted February 28, 2011 Another p500-1bd. Sorry, should have listed that. The subs will be wired to 1 ohm each as well. Link to comment Share on other sites More sharing options...
bkolfo4 Posted February 28, 2011 Report Share Posted February 28, 2011 One chamber is fine. Wattage will be close enough if they are the same model amp. You can use a DMM and a 50 Hz tone to get the voltage pretty close to the same coming out of each amp.

SwaggerWagon Posted February 28, 2011 Author Report Share Posted February 28, 2011 Do I just adjust the gain when playing the 50 hz tone to match? I'm a little OCD about my car and system lol Link to comment Share on other sites More sharing options...
cqtama Posted February 28, 2011 Report Share Posted February 28, 2011 hook a dmm up to the amp play a 50htz tone and make sure you have the same voltage coming from each amp. then you'll be good. R.I.P '01 blazer you treated my ears well until your transmission blew up.
