[QUOTE="blazian87, post: 8399445, member: 574798"] I like your enthusiasm. I doubt that the shop will sit down and show you the ropes to tuning an active setup without paying them. It is pretty time consuming that's why. You can do it at home by yourself for the most part if you do your research but a lot of it is personal preference. It's best to understand what each thing does by actually sitting in your car and listening to it while you change one thing to another. I've never had good luck with auto time alignment so if you decide to use it, use it as a start and go from there. Same applies for Auto EQ. Factory speaker locations are fine but do you have sound deadening inside your doors and seal it up good? That's very crucial to getting the cleanest sound out of your mids. The farther the speakers are away from each other, the more you have to time align and harder to blend. Crossover slopes are pretty important when dealing with active speakers because it will make a speaker sound more narrower/sharp or wider/smooth blending. For tweeter and mid, I would recommend starting at -12db/oct slope to get a good start. If you feel you need to sharpen up the tweeter or something, then move it to -18db or -24db slope for a much sharper sound.

Can you list your equipment here and what other work you have done to your car? speakers, subs, amps, HU, electrical, etc.. How did you set your gains for everything so far? [/QUOTE]
