[QUOTE="gunz4me2, post: 6508260, member: 613729"] The X1 or X10 setting is just a multiplier on the crossover. Let's assume you are tuning your crossover for 80 Hz at X1, if you engage the X10, that frequency would be 800 Hz. I ran a set of the Alpine Type S coaxials and didn't find them to be all that great. They have almost NO output from 80 to 120 Hz and I found the midrange to be quite dirty on them. I switched them out for a set of Type R woofers, which sounded much better on the midrange, but still lack output in the 90 to 120 Hz range. Unfortunately, I am limited in that particular vehicle by door depth, so I am going to have to do some custom work to accommodate anything deeper than an Alpine Type R woofer. When it comes to setting one's gains with a DMM... a DMM should only be used to get one in the ball park and should NEVER be relied on as a means to an end. In other words, sure it is nice and what not to set your gains via DMM BUT your amplifier is going to respond differently once you load it down with drivers. Learn to trust your ear! Also, DO NOT make the mistake of leaving your speakers connected when setting the gains via DMM.... Unless you have the desire to replace those drivers.
