Ive recently bought a set of MA Audio component speakers (5 1/4, tweeter and crossover)...Qusestion: How are you supposed to wire it? im confused because i want to have those speakers up front and 6x9s in the back too..the problem is, the wiring diagram shows that the corssover needs a high AND low input for each crossover (theres 2 obviously)....so if you know what i mean, the crossover needs all of my speaker connections and now theres nothing left for the 6x9's...what am i supposed to do?

Why would a crossover need high and low inputs? It's purpose is to split up one signal into different frequency ranges, so already having it split up would make no sense.
All the crossovers I've used only have one input (run wire from amp and your done). Try just attatching one to the high or low and see what happens then switch. Or, try running both off of one signal (in parallel) like this.

A paasive crossover does not need a "high and a low input." You are misreading the instructions. A 2-way crossover will include both a high and a low OUTPUT. Your woofer connects to the low output and your tweeter to the high output. Some crossovers are stereo and have both left and right inputs, and these will have TWO sets of high and low outputs. Read your owners manual and installation instructions. ------------- Support the12volt.com

thanks guys! i looked over the instructions again with a fine tooth comb, heres what the diagram shows however. See how theres inputs for both high and low, what am i supposed to do? parallel wire like TAudio suggested?

This does not look right to me, I do not understand what the purpose of a crossover would be if the signal is already split between high and low. ------------- 2000 BMW 540i 6 speed

What's the make/model of your crossover? Usually "high input" refers to a speaker level signal and "low input" refers to a line-level signal. I need to look this one up. Post make/model, please. ------------- Support the12volt.com

If it was a low-level input wouldn't it also need a power input to boost it to a level that the speakers will play? That would just mean this crossover is a dumbed down amplifier...

That's why I'm confused. I need to look at the manufacturer's specs. ------------- Support the12volt.com

The reason crossovers have to inputs usually is so that you can bi-amp them (power the lows with one amp or amp channel and the high with a different amp or amp channel).

Actually, this is not at all uncommon. Your crossover is capable of a bi-amp application as shown in the schematic you posted. Look in your packing for a jumper strap or wire that will combine the woofer and tweeter input positives and the woofer and tweeter input negatives. If you don't have one, simply use a short length of speaker wire and run that from the inputs as I just referenced. Run your front channel speaker lines from your amp/head unit to either the woofer or tweeter inputs (you just jumped them so now it won't matter which you connect to) and run your rear channel speaker lines to your 6x9's. Finally, remember to use appropriate crimp or solder connectors and don't turn anything on until you've made all your connections. I can't tell you how many times I've seen wires short out or an amp run with no load. Neither one will prolong the life of your equipment...

This is indeed a case where biamplification is a possibility. It is not new or that uncommon actually. There should be enough info for you listed by those above to get you on the right track.
