The owners manual doesn't say. Here is a link to the Owners manual on alpine,

The outputs on my HU are 4V, I have an Alpine CDA-7893 Unit.

Rep Power: 0 yea, I just looked at the specs and your right, Maximum Pre-Out Voltage 2V/10K Ohms. Does that mean I have to adjust the gain even lower or something?

Ok, let me tell you this then. At one point, I had my amplifier professionally tuned with this new set of XRs. Here's what happened at the time that caused me to have to change the settings. Basically, when my car was at rest, in the garage for instance, and I was listening to my components at a high volume, even with the gain half-way set, the speakers didn't make this cracking/popping noise. But when I started driving, the tweeters just start doing it all of a sudden. When I got it professionally done, the people obviously didn't hear the cracking because it was at rest. Well they told me that it didn't have anything to do with tuning, and that id have to pay to get the entire system looked over. Now I know for a fact that the XR crossovers are good, I switched them with my old ones and the same thing happened. I also know that my wiring is perfect, power wire on one side, RCAs on the other. I am just starting to think that it has to do with the type of amplifier that I have as well as the aluminum dome on these tweeters. But whatever, right now I have the HPF pretty high and the gain a notch below half and on the XR Crossovers I have the jumper set to High Mid Bass and I have some midbass coming from them, it isn't all flat anymore in the front. I want to say that for this particular setup, the amplifier has to have a high HPF in order to comply with the components, some amps may work differently with some speakers than others. But thats what I think.

Rep Power: 0 This is going to seem pretty stupid since I have been posting so much, but yesterday I was messing with the settings on my amplifier, I turned the gain down another notch, so it is only a quarter of the way up now. The volume went down somewhat, but the static didn't come through the tweeters. It is weird because if I recall, when the gain was set that low, there was still static. But anyways, so far I haven't heard any static and I set the tweeter jumper in the XR Crossovers to +1.5dB and the mid jumper to high mid and it sounds really good now. The only thing is that from what someone told me, if the pre-outs are 2V, then the gain should be set 1/4 of that, or something like that. If thats the case, I would think that the gain could go up higher than a quarter of the way on the ****. Maybe im still unclear about how the gain works. If someone could enlighten me again, it may be helpful.

Rep Power: 313 the gain is used to match up the voltage of the radio to the input stage of the amplifier. setting it to 9 volts when the radio puts out 2 volts underdrives the amplifier, while setting it to .25 volts when the radio puts out 4 volts has the potential to clip the crap out of your amp!
contrary to popular belief, its not another volume ****!
this isnt to say that you need to set your amp gain to the 4V position if your radio is rated for 4 volts out, there is a balence. the bottom line is that it doesnt matter whether its 1/4 the way down, 1/4th the way up, or pointing at the 1.5V tick notch. its set in the position that provides hte best clarity of sound if you like quality, and the position that provides the greatest potential for volume without harming the speaker for block-rockers.
its probbaly the #1 reason enthusiasts retune their amps from shop settings. some tune for quality, some for max volume before safety. and itll be the opposite of what the consumer wanted.
