Seymore Posted April 10, 2014 Report Share Posted April 10, 2014 So the way I see it, DD-1's and oscilloscopes can only measure your deck or amplifier's output. But say that you have a 1500w amp and a 600w sub, how can you make sure your sub's getting it's RMS with a multimeter and some math? is there a formula for box rise?Don't really know much about this part of audio, but i'd love to learn :/ 2001 Civic LX SedanPioneer DEH-7500HD Big 3 in 1/0 Knu CCARockford P500-4RF Punch P165-S in doorsRF Punch P165 in rear deckFront doors deadened with DamplifierNextSQ's new HDS208 8" in a T-line whenever it FINALLY COMES OUT I CAN FINALLY AFFORD IT Bend over and I'll show ya. how is it 2 days work? half a day at most, i may be an idiot, but im not an idiot.

Seymore Posted April 10, 2014 Author Report Share Posted April 10, 2014 I know the formulas for ohms, volts & watts by heart, and amps/volts/watts ect, but I'm mainly concerned about box rise in this post. 2001 Civic LX SedanPioneer DEH-7500HD Big 3 in 1/0 Knu CCARockford P500-4RF Punch P165-S in doorsRF Punch P165 in rear deckFront doors deadened with DamplifierNextSQ's new HDS208 8" in a T-line whenever it FINALLY COMES OUT I CAN FINALLY AFFORD IT Bend over and I'll show ya. how is it 2 days work? half a day at most, i may be an idiot, but im not an idiot.

Joe X Posted April 10, 2014 Report Share Posted April 10, 2014 Impedance rise only occurs around two narrow ranges of frequencies above and below tuning, only if you are burping near or within those ranges it may be of concern to you. You can roughly tell how much power is going into a sub by clamping. Link to comment Share on other sites More sharing options...
Seymore Posted April 10, 2014 Author Report Share Posted April 10, 2014 Clamping, as in using a multimeter or something like an amp dyno? 2001 Civic LX SedanPioneer DEH-7500HD Big 3 in 1/0 Knu CCARockford P500-4RF Punch P165-S in doorsRF Punch P165 in rear deckFront doors deadened with DamplifierNextSQ's new HDS208 8" in a T-line whenever it FINALLY COMES OUT I CAN FINALLY AFFORD IT Bend over and I'll show ya. how is it 2 days work? half a day at most, i may be an idiot, but im not an idiot.
