HU Crossover or Amp Crossover??

Recommended Posts

Just purchased a Sony HU that allows me to set crossover points. Does it affect the sound or make a difference if the xover is set with the amp or the HU. I would prefer to set it on the HU as I can pick the precise Hz, rather than guessing on an analog knob. I assume that I would just need to turn all xovers on the amp to their base numbers and let the HU do the work. Does it make a difference? Thoughts?

If you use both crossovers you would change your slope and you my have under over lap frequency gaps ..it’s best to use the decks crossover and set your amp flat and bypass ..

How do you turn the xover off on a sub amp that has no on/off switch?

It should have a "full pass" setting or something like that.

I read that I can turn it to 250hz which would be basically turning it off

if there isnt a full pass switch, just turn it all the way to the highest point so itll interfere as little as possible

If the amp lp is undefeatable id just use the amps LPF like I said using multiple crossovers deck processor amp ..ect increases your crossover slope and will have weird effects on the sound ..your deck should have a setting for through but still maintain the sub level for adjusting bass level ..I’ve done a lot of research on this area when I was competing ..because a lot of the bigger amps had undefeatable crossovers as well ..I’ve gained over a decibel in competition by just using the amps crossover and bypassing the decks internals ..

Can overlap and gap be used in same context 😂😂😂 

Ok so it's best to use deck. Great thanks answers my question.

Incressing slope does not always equal bad effects 

Ok so it's best to use amp. Or not! Lol

I like to use both. Is there not an application for this? Why choose between hu with limited frequencies cross or amp with limited slopes ect. Using both will give steeper slopes and more frequencies to choose from. sometimes this is encouraged/sought after. No? Thanks

When traffic was booming, we had a big team of mods, but I think I am the only remaining original moderator.  But there are a few others, overall there very little moderation that is needed anymore.

I prefer a switch or numerical value over a sweep knob where you have no idea what value youre actually setting it at. So in this instance, i would presume the HU has actual numbers and i would use that.
