i am now on my second 12" L7 sub and i dont want to blow this one and go through all of the trouble of getting a new one again, i have been told that the break-in period for one of these is 500 hours. This sounds rediculous to me, when can i turn the amp way up and pound this sub hard? the amp is a kicker zx 750.1 I have been playin the sub at about 1/4 power on the amp and about 1/2 bass boost for a little over a week now.

Yea, 500 hours.... you just keep playing that sumbitch and tell us how it really sounds.... 3 years from now


I played mine at about 30 - 40% for about a week to a week and a half.... been bangin' them for over a year and they still sound great....

I know I will get jumped and bashed for saying this. But I installed Kicker subs for a year and a half and I replaced so many of them because they weren't "broken in" that I lost count after the first couple months. And I would have the same problems with them in Kicker's prefabbed box, so the problem was not my box. I wouldn't even use a Kicker sub for a paper weight I hate them so much.....

But that's just one man's experience and opinion.

Just don't rag on it for the first couple days and let all the parts that flex loosen up a bit. And MAKE SURE you aren't getting any distortion through that sub or you will be replacing it again.

I've been told to give it about 2 weeks minimum
. Personaly, at the start of the second week I would slowly start "Pushing the Bar" a lil' higher with the gain on my amp (KX850.2) and turning up the Vol as well :D

If you gotta turn your amp up over halfway thats your problem there.

I had alot of problems with those subs in a sealed box. Ported they work much better. In the sealed they always burn the lead wires from the connector to the voice coil. Good luck with your sub.

s**t, when I have Cerwin Vega's, I went through at least 2 subs every 4 - 6 weeks b/c I would just through them in the car and start bumpin' away.... of course I was also running a Rockford amp....nuff said


Lay them low for about 10 days, its worth the wait.

The high-performance suspension system makes the speakers very stiff "out-of-the-box". Approximately 2 weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. A "broken-in" subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

thats what i heard also... so play your Southern Smoke and 3 6 mafia, and Young Dro-Jackie Chan song at a decent volume...like where u can talk a lilttle bit inside to somebody...it will loosen up the speaker surround some.i'm sure u notice quality speakers are always super stiff out of the box.

The only reason you have a gain knob on an amp is to match the ouput voltage of your head unit. It should not be used just to "make it louder". If you have a head unit with 2 volt preouts then your amp should be matched to 2 volts. If you have it turned up more then you will be sending your speaker distortion and it WILL blow.

If you have to turn the gain up on your amp too much then you need more power.....

here's how to set your gain.... turn the gain on the amp all the way down... then turn the headunit all the way (or most of the way) up... then, go to your sub amp, and tuen it up until it starts to distort... turn it back down a bit, and you're set... This is the non DMM way to do it, but Ive been doing it that way for years, and Ive never blown a sub in my life...

also, for break in, Id keep it low for a week or too at least... just dont beat the **** out of it at first..

that usually means it should get less power... sealed is usually the higher powered setup as opposed to ported...

Ive got absolutely 0 practical experiences with l7s though, so Im not sure.

I have 4V preouts on my head unit, but several "gain setting calculators/tutorials" say my amp should be set at 69V :confused: .

You would get 69v on the output section on your amp. This is how I would set up a customer's system back when I installed ( link )and I NEVER had someone blow a speaker that didn't mess with my setting after they left (not counting Kicker :D ). Once I did it a couple times, I could tune a whole system in about 10 mintues or less depending on how hard it was to get to the amps. Although it is for a JL Audio amp, the only difference will be the actual voltage settings. Just refer to your manual or call whoever made your amp and they will know. Just make sure you have your car running while you do this so you will be getting 14.4 volts (or close to it) to the amp. If you do it without the car running you will only get 12.5 or so, and your settings will be thrown off once the amp is seeing more voltage. If you blow a speaker after setting it up like this your either don't have enough power for that speaker (I have never seen too much power blow a speaker), or your box is not built to spec.

Subsonic filter should be set right about where the box is tuned. If it is tuned at 30hz then you should set the filter at 30-32hz depending on the slope that the filter works on. If it is 24db/octave then you can safely set it at the same freq. as the box is tuned. if it is 12db I would set it 2hz higher than the box is tuned. As for bass boosts......I never use them and would never use one on a ported box. This is how I do things, someone else might have another way. I hope this helps.

im confused on your response to the subsonic filter, on the amp there is a switch that says subsonic on or off, what should i do?
