Hi I've purchased a Skytec STP-1 crossover. This is so I can take the 8 ohm output from an amplifier (100w) into an 8 ohm guitar cab (140w). The crossover splits at 180Hz which is ideal for me to protect the speaker against damage from low frequencies from my bass guitar. By using it this way I will only be using the high output from the crossover and not plugging anything into the sub output. Does anyone know if this method is ok? I don't have a high level of knowledge when it comes to the components in a passive crossover so am a little anxious that I could adding 1 + 1 and getting 3 here!
