EASY PASSIVE CROSSOVER QUESTION

bdgf2004 · 17th April 2011, 04:30 PM

i understand how the basic crossovers work and i use some calculators on the internet. but usaully when i hook something like this up i do not bridge the amp. in this case i will be bridging the amp which means both of outputs will have power (2 inverted signals), not one terminal with power output and one with only a reference. my question is should i install the crossover (1st order) on the positive terminal only like normal or should i have to insert a cap on both terminals? it just seems like to me that if i only install 1 cap on 1 speaker terminal there would be some sort of colflict.

One of the bridge terminals starts out being the "+" and still is after bridging. Use it for +

okay. it just seems like that would only filter half of the signal going the the vioce coil
