Alpine IDA Series Crossover (?)

[liquidfluidity 10+ year member]

Probably a newb question but this will be my first HU with a crossover. Is the crossover active when using the internal amplifier or just when using external amplifiers?

The IDA series can not go active. Read the active vs. Passive sticky in the speakers section to understand what active is.

Ok , I pretty much knew that but does the fact that it has a choice of specific points to choose from , and not infinitely variable , make the crossover on a IDA-X200 passive?

Well, technically, any crossover on any HU is active. A pre amp crossover is considered active while a post amp crossover is considered passive. However, the term "active" is commonly used for a networked crossover system. This would be a crossover system that:

1. is a preamp crossover

2. let's you lowpass a sub, bandpass the mids, and highpass the tweeters

3. is usually a stand alone processor or built into a higher end HU

When you mentioned active, this is what I thought you were talking about.

the models that can use the imprint can be active. read the manual.

Ah yes, and if you did want to go "active" with it, you can use the Imprint kit which can be purchased seperately. Good call nineball. I forgot about that.

keep in mind the sq from the ida line, even with the imprint, sucks.

Ok guys , back to my question - does the crossover in the HU actually function when using the internal amplifier(of the HU). Say I am just to hook speakers up to it , will the x-over work that way or will it only function with the pre-outs in use? Hope this makes sense. Thanks for replying and the info , guys

The crossover will work with the internal amp or the pre outs.

you are kind of asking 2 different things. you can use the hu sound controls (bass/treble only) with the internal amplifier or the pre-outs. if you want to run active, or use the imprint crossover network, you have to use the pre-outs.

Thanks nineball. That's exactly what I needed to know. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
