Setting crossover...which is the lesser of two evils?
This is my first time installing equipment modern enough to have a built in crossover! We just didn't use to worry about such things.
New amplifier with built in crossover. Crossover offers three settings: flat (crossover off), 90Hz and 60Hz.
The Infinity 4x6 component speakers are rated to reproduce sound down to 72Hz.
So which is worse...choosing 90Hz and losing some bottom end reproduction (but perhaps saving the speakers), or taking your chances on speaker damage and getting all of the low frequency response you can out of the speakers?
FYI: The car has the UQ7 factory sub-woofers, so they will help fill in on the bottom end some.

Re: Setting crossover...which is the lesser of two evils?
I personally run my cut off frequency for the 4X6s on the higher end(90Hz in your case).
I don't really notice any difference in additional low frequencey sound if I try to get my 4X6s to produce anything lower, and the possibility of distortion(and subsequent speaker damage) is increased when trying to have the 4x6s reproduce lower frequencies.

Thanks Zane M. That seemed like the safer answer.
Everyone agreeing with this?

Are you certain that's not a low pass crossover? In other words, it allows 60hz or 90hz AND BELOW. What's the brand and model of the amp?

It says high pass, but I appreciate your asking. As I mentioned at the start, while I understand the concepts, this is new territory for me.

Re: Setting crossover...which is the lesser of two evils?
In that case, I agree with Zane...90hz. That gives you a little wiggle room to allow for roll off.

Super. Thanks guys. The switch is set, and once I bury this thing in the dash, there will be no changing it!
