Prob always there just can't hear it at higher volumes. Check the grounds of the amps an the Caps if you have them. Then check the preamp wires from the head unti to the amp. Keep it as shielded from power wires as you can. Some times tying a ground from the amp back to the head unit ground can fix a hiss or static

Hello. I do speaker reconing and amp rebuilds for a living and the L7's often suffer from tinsel leed wire breakage which can cause "poping" and "screaching" noises in the sub in various cone positions. You need to remove the sub and push straight down on the cone repeatly and determine if you can feel or hear crunching noises to make sure the voice coil and/or spider are not damaged. A faulty leed wire can usually be identified by a dark spot or obvious breakage. All of the L5 and L7 models can be successfully repaired as long as they are the older models that have a center cap in the cone. The newer capless models will have to have an upper brace cap glued to all of the cone's fingers and will have a rather ugly appearance. Leed wire overhauls usually run around $30.00 for the older models. Voice coil and spider overhauls run around $90.00.

Run the subs in series then bridge the amp. So run the normal + to - to the one sub then hook up a spare wire (not connected to the amp) to the same + and - connections. Then run the spare wire to the + and - of the other sub. This will tie the 2 together so you can bridge the ampfor more power instead of using 2 seperate channels.

You had the settings set incorrectly and overdrove it. The voice coil leads are burn't open. If you look at the little flexible braids by the terminals I'll bet they are black/brown and maybe even burn't in half. It's toast.

It could be your receiver but you can try seeing if the Woofer has a input knob at the back, maybe this down, or maybe.if possible turn down the amount going to the woofer with your receiver.

Well, you have the 4 ohm dvc kickers, and your amp being stable to 2 ohms doesn't go together very well. If you wire the voice coils in series, and hook the speakers to the amp in parallel, you get 4 ohms, which doesn't use all the power your amp is capable of. If you run the voice coils and the speakers in parallel, you'll drop the resistance to 1 ohm, and probably fry the amp, or at least deal with overheating issues. Better be safe than sorry. You need to run each speaker in series, which means running a positive and negative to each speaker, and a jumper from those terminals to the opposite colored terminals on the second voice coil. Diagram can be seen here: http://www.kicker.com/06/tech-support/manuals/manuals/02SoloBaricL7manual.pdf That puts two 4ohm voice coils in series, and raises the resistance of each speaker to 8 ohms. Then, you have to run both speakers in parallel to the amp. When you run two 8 ohm circuits in parallel, the total resistance of the circuit is 4 ohms. That means seperate positive and negative wires to each speaker. If it is a mono amp, connect both negatives to the negative output, both positives to the positive output. If it is a multi-channel bridgeable amp, You'll probably connect the negatives to one side output (right for example) then connect the positives to the opposite side output (left for example). If you need to bridge your amp, make sure it is bridgeable, and also that you have the speakers bridged to the proper amp outputs. If not sure, reply back here with the amp model number, and maybe I can help you further.Thanks, and I hope this solves your problem.

take off the outer ring then take a razor to the under part of the rim . carefully cut the sillacone glue from the metal rim .After that remove the coil fin the same way . find the wire and take really thin solder wire and use a very small amount to repair

Hi Hector, if all the wiring is connected properly, you then mite have a problem on the circuit board, or with the subwoofer itself. While its switched off try moving the switches one or two times just in case there is a dry contact. Next would be to take in the unit for an independant bench test before opening the unit. Cheers.

About all you can do if your really wanting to "fix" it, is tear it apart & completely recoil both voice coils.
Otherwise you can just run it on the one good side like a single voice coil sub.
