I have a set of boston 6.43's and I'm not sure how to hook them up.Would I use the lowpass or the high pass input on the crossover?I'm running it in just 2 channel stereo.

 

You want to highpass them...


Id start at 50hz and work up from there to see what sounds best...

 

I dont know,I'mvery new at this.I will be running them with a punch 400x4 bridged into 2 channels.I will have the 3 speakers hooked to the 3 way crossovers and one side of the amp will run each crossover.Not sure to use the high or low input of the crossover?I'm sending a full pass to the crossover and want it to do it's job from there.

 

Could you post a picture of the crossovers? I would like to see exactly what were talking about.. Something sounds strange here....

You should be running fullpass (or, as suggested, highpass crossed at about 50hz) from the output of your amp into the crossovers' input and connecting each component to it's proper output on the crossover.. It should be marked which component goes where.. Just post a pic and I can help you out more if you're still confused..

 

if you're using the stock x-overs that came with the 3-way set, what's the problem? a full range signal out of the deck, and amp is what you want going into the x-over... am I not understanding what the problem is?

It doesn't say full range on the crossover,it has high and low pass inputs.I will be running fullpass from the amp and going to the highpass on the crossover.It is the original 6.43 crossover.

 

^ It sounds like your passive crossover has "bi-amp" capability where you can run the midbass on a separate amp from the rest. This is usually considered a nice feature to have.

Most passive crossovers with this feature have a switch or jumpers on the circuit board that enables or bypasses the bi-amp feature so you can run off just one set of inputs. If your passive crossover does not have such a thing(I've never seen one that doesn't), just split your speaker leads to both inputs.

 

thank you,that must be it.I have jumpers that you can put on normal or by amp.If that is the case,I will set at normal and hook the speaker wires on highpass?

 

^ If you put it on 'normal' and not 'bi-amp' then either set of input terminals should be fine. I would try the 'high' first.
