Setting crossover on amp question...

[Hercules 10+ year member]

Hi all,

I bought a Kicker ZX700.5 amplifier. There is an option on the amplifier to set the internal crossover to off, or high. If I have component speakers with its own crossover in the front, and 6x9 3 ways in the rear hooked up to channels 1&2 and 3&4 respectively... should I have the amplifier crossover on or off for the channels, or some combination?

Let me know... just trying to make sense of it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thanks!

You'll want your crossovers set to high pass.

Both sets to high?

Can you explain why? I am just a little confused because I have a crossover for my front components alone... so I'm curious. The manual states:

In the OFF position the amplifier passes a full-range signal to the speakers. The HI position should be selected when connected to speakers, which you do not want to receive any sub-bass information.

Isn't the front crossover supposed to take care of that?

I will follow your explanation, but I just want a little insight into the logic //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Setting your crossover to high will probably protect your speakers in the long run. Try hooking them up with the crossover off and tune it to how you like at the volume you will listen to it at most often. If the speakers seem to perform how you'd like them to, then leave them be //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif If your midbass sounds kinda crappy, you may want to try throwing your crossover on.

*Edit: what kind of speakers are we talking about here?*

Alpine Type X 6.5 Comps in the front, Alpine Type S 6x9s in the rear.

I would cross them over, if you are using sub(s). They will let you turn up the volume higher without the small mids overexcursing. Putting a high pass filter on your mids works the same way as the built-in high pass crossover on your components for the tweeters - it limits lower frequencies (excursion) from distorting and/or damaging the drivers. If you don't have subs, then at least crossover the 6.5's. I would highly recommend subs, though.
