break er in

[Braindead]

So to break in my ab xd's should i just keep my gains at half for a week or so, and turn it up once i can press on the cone and the suspension's loosened up?

you already know the answer. no you dont need to break in subs.

Does it matter how quickly i push the suspension to its max? Like would it damage the suspension to push the full 1200w to them on the second day?

It will if you think the gain is a volume knob.

Ah. Duly noted. I'll keep the gains low for a little while

They're nice subs but not terribly stiff in the suspension, so while you should expect to hear a change in output as they loosen up, you don't need to go easy on them. They will be breaking in for quite a while until they eventually stabilize, but for daily listening it's nothing to adjust the gain for.

Do you know of a shop or local enthusiast who can tune an amp with an oscilloscope or DD-1? You really should have your head unit's pre-outs checked to know when they distort and of course get the amp set so you know it's not clipping hard.

I'm not really sure if there's anybody in my area who can help me, i'll just have to guess. Can i hear clipping?

ive always played any new sub i got free-air on a 20hz tone on low power for a few min before i install them. dont know if it helps and honestly i dont care. i will keep doing it simply because subs loosen up as they play, and giving them a chance to loosen before you throw full power at them cant be a bad thing.

You shouldn't set the gains on a sub amp with the subs connected, at least that's my opinion because the test tone gets loud enough to cause pain. You can do the DMM method and set the gain to make less than the RMS power rating of the amp, and on that amp it shouldn't be clipping. The output on music will change constantly, so your #1 priority is getting the gain close enough to the input voltage so you're not clipping the amp hard.

A lot of people set their gains by ear on their loudest song, and when you turn the gain up and it stops getting louder that's when it's clipping. Some people can't hear the bass getting crappy sounding from clipping or distortion but you can hear when it's no longer getting louder.

I have a dmm, should I set the gain around 1250w rms then mark the spot on the knob? Also I should avoid bass boost on my HU and amp right?

Also what test tone should i look to download?
