Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 466 Registered: Oct-05 | ok this is really starting to bug me this is my 3rd 15" kicker l7 i blew this time i even turned the bass boost off and set the gain not even in the middle and it played for about 2 days and blew apart again. idk what to even do anymore because i set the amp really low and it still blows. what else could be the problem i have a really really big box tuned to 35hz and i have the sub facing upwards because it wont fit in the trunk standing straight up could the box have anything to do with the problem because idk what to do anymore |

Silver Member Username: BasssquaredKansas Post Number: 774 Registered: Nov-06 | i was just playing but you should check your voltage i think your clipping the sub |
Gold Member Username: Van_manBoston South, MA Post Number: 2583 Registered: Mar-06 | what are you feeding it? As far as rms? What amp, what vc L7? whats the box size? A 15 L7 will take 1500-2000 wrms easily. |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 468 Registered: Oct-05 | how do u check the voltage how would the voltage damage my system tho. the box dimmenisons is 37.25" x 17" x 14" tuned to 35hz |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 469 Registered: Oct-05 | it has the kicker zx1000.1 amp so its only gettin like 1100 watts. its wired at 2ohm |
Silver Member Username: BasssquaredKansas Post Number: 776 Registered: Nov-06 | hahahahahahahahaha how would the voltage damage my system thats a good one |
Silver Member Username: ImalikSD2.5......ED9.1=Boom, New Jersey Audioque...N... Post Number: 390 Registered: May-06 | Do you have a DMM? you just cant put the gain at halfway...there is no way you should be going through L7's like that. |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 470 Registered: Oct-05 | no i dont have a dmm, and thats why i was wondering if the big box would have to do anything with it its 37.25" x 17" x 14" tuned at 35hz. |
Gold Member Username: WingmanaliveA pic is worth 1000 posts!! Post Number: 7934 Registered: Jun-06 | That's around 5cu's. Shouldn't be the problem. You sure it's wired right? Have an angry ex with keys? |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 471 Registered: Oct-05 | what else could it be do i need to get a new battery or sumthing or alternator my alternator is 90amps. could these be the reason why the sub keeps ripping apart and i mean ripping apart by the black plastic part near the voice coils. |
Gold Member Username: WingmanaliveA pic is worth 1000 posts!! Post Number: 7937 Registered: Jun-06 | The spiders? No, you said plastic, hmmm. Sounds like over excursion. Three in a row is pointing to the install/settings. A bad alt could mean clipping if the power isn't there. Do the lights dim? I have zero experience with Kicker so I'm just throwing sh1t out there. |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 472 Registered: Oct-05 | no the lights barly dim at all thats why idk what the problem could be. the longest the sub lasted out of the 3 was like 2 days. and i turned the bass boost off like ppl recommended and i still get the same problem. Does is sittin cuz i have the box laying down with the sub facing upwards cuz the box wont fit in my trunk standing up |
Gold Member Username: WingmanaliveA pic is worth 1000 posts!! Post Number: 7939 Registered: Jun-06 | No. $20 DMM is next. Let's make sure the numbers are good. Your gain should be set according to voltage not "around half". All I got. My drink is empty. |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 473 Registered: Oct-05 | where can u get a dmm at and is the directions self explantory on how to use it. and what should the numbers be saying |

Silver Member Username: Skibum12189Cleveland Post Number: 797 Registered: Mar-06 | with a 90 amp alt, he should be fine |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 474 Registered: Oct-05 | so with the dmm when i go to use since my amp is zx1000.1 which is 1000 watts is that what im gonna be looking for on the dmm meter? |

Gold Member Username: WingmanaliveA pic is worth 1000 posts!! Post Number: 7943 Registered: Jun-06 | Looks like 44.7. |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 475 Registered: Oct-05 | i got the pioneer premier mp780 and i have the equalizer set to vocal and the loudness on because it makes the music sound better? couldnt i still set the gain by leaving that stuff on because thats how i listen to my stuff |
New member Username: FlakkoPost Number: 2 Registered: Jun-07 | its called clipping. i like to set the gains by ear. play a song that bangs, or use a 60hz test tone and turn the gain up gradually until you hear stress on the sub then back it down a little until you dont hear it anymore. if you can't do that, dmm liek stated above. |
Gold Member Username: WingmanaliveA pic is worth 1000 posts!! Post Number: 7949 Registered: Jun-06 | Turn it all off. Gain, BB, loudness, it all. You're looking for a base level to set the amp's gain to. Did you read the link? "Disconnect speakers. Turn your gain/input sensetivity all the way down. Turn off bass boost and any crossovers. Turn on your head unit. Set the volume control to 3/4 of full. Set all equalization and bass/treble controls to zero. Turn OFF loudness and BBE processing. Probe your amplifier's outputs. Insert your tone CD. Select a tone within your amplifier's playing range. Play your selected tone and adjust the gain until you reach your target voltage. Reconnect your speakers and verify proper operation. Set crossovers and adjust levels for proper tonal balance." See, now I'm turning to rum. I like rum. This is where the picman comes out lol. Naw, just kidding. |
Gold Member Username: 420alldaylongPost Number: 2122 Registered: Sep-06 | What ohm is the sub? How big is the port?LxW |
Silver Member Username: Kpa2727Post Number: 152 Registered: May-07 | brings up a intresting point, not to jack a thread but simple question, since my hu is wired to my speaker is it ok to set my gain with the speakers connected? |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 476 Registered: Oct-05 | this is the box im using for the 15 and i still dont know why 3 l7's went by that fast and only lasted for 2 days the longest. http://cgi.ebay.com/15-CUSTOM-KICKER-L5-L7-SUB-BOX-S15L5-S15L7-3FT-3-35Hz_W0QQit emZ170124653583QQihZ007QQcategoryZ18804QQrdZ1QQcmdZViewItem |
Silver Member Username: ImalikSD2.5......ED9.1=Boom, New Jersey Audioque...N... Post Number: 392 Registered: May-06 | The box is not the problem...Do you have the correct VC settings for your subs? Are they 2 or 4 ohm, This may help you out http://www.rockfordfosgate.com/rftech/woofer_wizard.asp |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 477 Registered: Oct-05 | yes i know its wired correctly because when i wired it wrong before the amp wouldnt let me play and would just go right into protection mode. the sub is dual 4 ohm wired down to 2 ohm load. |
Silver Member Username: CriedErie, PA US Post Number: 473 Registered: Jun-07 | How come in the video, it looked like he had speaker wire hooked up, and most places say disconnect your speakers? Hmm.. |
Gold Member Username: InsearchofbassPost Number: 5415 Registered: Jun-04 | yes i know its wired correctly because when i wired it wrong before the amp wouldnt let me play and would just go right into protection mode. the sub is dual 4 ohm wired down to 2 ohm load. A) a dual 4 ohm can only be wired 4 or 2 ohms how is it that the amp wouldnt come on? it should come on at either ohm id think |
Gold Member Username: InsearchofbassPost Number: 5416 Registered: Jun-04 | opps i meant 2 ohm or 8 ohms |
Gold Member Username: InsearchofbassPost Number: 5417 Registered: Jun-04 | are you sure your port is tuned right??? |
Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 478 Registered: Oct-05 | yes i know it comes on when it was wired wrong but everytime it tried to hit the protection light came on like it wouldnt let teh sub play. |
