Can any of you audiophiles give me any advice on setting the crossover frequencies on my radio. I have a Kenwood DDX712 connected to the stock speakers and an Infinity Basslink sub, with the stock sub disconnected.

The sub goes from about I think 40Hz - 120Hz to Through.

What does this mean?

And I can also adjust the front and rear speakers.

 

your crossover frequency is the line at which your head unit (or basslink, in the sub case) stops sending signal to your speakers. in the case of the sub, your talking about a high-pass filter. this means that the sub is going to get all frequencies below this set frequency. i would set this at around 80 Hz. that's where mine's at on my T110d2 and it sounds great. this is all a matter of personal preference, so play with it.

as for the head unit crossover points, you're talking about high pass filters. this means that your head unit will stop sending signal below these frequencies (at a given slope, usually 12 or 24 Hz per octave. this means the rate at which the signal will drop off below your highpass filter. the higher this number, the faster it drops off) to your chosen speaker(s). i have my high pass on my head unit set at 100 Hz, and a HP on my 4-channel amp powering my speakers at like 125 for my front speakers (5-1/4" components). again, this is a personal preference thing, so play around with it...

 

Thanks! I'll play around with the settings tomorrow see what I like.

 

Thanks for the advice, I played around with the settings and went with 80Hz to the sub and it sounds much better than it did on Through.
