ehh i free air a sub for a good 60 seconds at 60hz does the trick for me.

I'd go with the 45 min thing!! No way I could ever wait that long lol. I did listen to the RE8's at low volume for awhile, and turned it up little by little.

Although there are a few diff. methods, as stated before, i usually break mine in for about a week of driving. Keep all bass boost, loudness, etc off and just let the subs play at low volume. Kind of the same thing with a car...let it break in for a while, at varied speeds.

Cool, getting a sub soon, as soon as I get a few more things. Good information.

i had that question a few months ago... there were many different answers. some said play at moderate to low volumes for 10-20 hours, others said to blast them right off the bat. although both are diffrent methods i didnt see that big of a discrepancy in the end result. because after all the reason for "breaking them in" is to loosen the material in the sub.

the sub will sound different after it is broken in. hope that helps

some are skeptic about breaking in subs... some say do it, some say it doesnt matter.. its up to you.. but im sure you want to play it safe... so play some songs at medium/moderate volume, with everything set to 0.. do this for around 45 minutes or so.. or you can play like a 20hz tone for about an hour or so... this is just to burn the excess glue off and losen it up some.. i have a 12" Type R and it will take about a week or a little longer for it to shine.. also the Type R can handle more than its rated for.. im powering mine off a JBL 600.1 and it does fine.. some even power then with over 1000rms.. but play it safe.. remember the gains arent volume knobs.. read the FAQ's for more..

i am about to pick my car up with an alpine type r swr-1042D 10" sub in a Q logic sealed box. please give me a guide to breaking it in, its my first ever sub or car audio aftermarket anything (i also installed 2 sets of components and a 4 chan amp).
