Bass boost knob broken

Hi, my bass boost knob for my subwoofer seems to be broken right off. When I remove the cover in front of the subwoofer, the chord is no longer attached to the knob, so it's broken right off. Is there any way I can fix this?

Need schematic diagram infinity basslink subwoofer


Design: The BassLink brings together a 10" subwoofer (treated paper cone, foam surround), a 10" passive radiator (to increase efficiency and limit distortion), and an extremely efficient, specially designed 200-watt Class D amplifier that work as an integrated system. Special circuitry monitors voice coil position to maintain linearity at high power levels, so you hear loud, clear bass.

Enclosure Type and Materials: The enclosure is made of an acoustically inert polymer which is rigid enough to resist flexing and dampens any resonance.

Servo-Control: The servo-control system continually monitors the performance of the speaker and ensures that the amplifier delivers exactly the right amount of power.

Class D Amplifier: This unit has a built-in 200 watt Class D amplifier which is highly efficient and designed specifically for use with the subwoofer and passive radiator combination.

Auto Turn-On Feature: When the speaker level inputs are used, the system will automatically turn on and off with the radio. Note: The auto turn-on feature does not operate when the preamp level inputs are used, unless the remote turn-on lead is connected.

Low-Pass Crossover: The low-pass crossover frequency can be varied from 50Hz to 120Hz for a seamless transition between the output of this unit and that of the other speakers in the vehicle. The crossover has a slope of 12dB per octave.

Bass Boost: The amplifier includes a continuously adjustable bass boost from -6 to +3dB centered at 40Hz.

Phase Switch: Allows you to select normal or reverse for best bass.

Mounting: You will be able to put BassLink in a variety of in-vehicle locations, thanks to its compact size and mounting feet that enable the rigid polymer box to be mounted vertically or horizontally.

Vertical Mounting Dimensions:
Width: 14.625"
Height: 13.375" (including feet)
Depth: 8.675" (10.076" including feet)
Horizontal Mounting Dimensions:
Width: 14.625"
Height: 9.5" (including feet)
Depth: 12.75" (15.1875" including feet)

BassLink LC Remote Level Control

Overview: The BassLink LC allows you to adjust the volume of BassLink powered subwoofer.

Installation: The BassLink LC may be mounted under the dash or may be dismantled and mounted inside the dash for a factory appearance.

Under-dash Mounting: Select a mounting location that allows easy, safe access to the control while driving. The BassLink LC has mounting "ears" to use as a template for drilling pilot holes. Attach screws through the "ears" to secure the BassLink LC to the mounting surface.
In-dash Mounting: Disassemble the BassLink LC by removing the Phillips-head screws on the front, rear, and top panels. Remove the bottom and side panels and disengage the RJ11 connector from the back panel. Choose a mounting location that allows easy, safe access to the control, and provides 1-3/4" clearance behind the mounting surface. Drill a 9/32" hole in the mounting surface. Feed the BassLink LC's potentiometer (with the knob removed) through the hold and use the nut provided to hold the control in place.
Connecting to BassLink: Route the cable behind the dash or other interior panels and under the carpet. Do not route the cable outside the vehicle. Connect the cable on both ends.

Inputs and Controls

Inputs:

Universal Interface: Front and rear, left and right Universal interface speaker-level inputs (for use with the supplied speaker-level input wiring harnesses)
Line Level RCA Inputs: Front and rear, left and right female preamp level inputs
+BATT (+12V): Gold-plated screw terminal, 0.350" wide
REM (remote turn-on): Gold-plated screw terminal, 0.350" wide
GND (ground): Gold-plated screw terminal, 0.350" wide
Fuse: There is an installed 20 Amp fuse
Remote Gain Control: Phone type jack for included remote gain control

Controls:

Gain Control: Rotary control that sets gain (variable from 250mV to 4V)
Crossover Control: Rotary control that sets the low-pass crossover point (variable from 50 to 120Hz)
Bass Boost Control: Rotary control that sets bass boost level (variable from -6 to +3dB, centered at 40Hz)
Phase Switch: Selects normal or reverse phase (0 or 180 degrees)
Power LED: The power LED glows red when the BassLink is on
Servo LED: The Servo LED glows green when the servo circuit has determined that the woofer has reached maximum excursion and power to the woofer has been modified to provide maximum performance. The LED should light momentarily during high-level bass transients. Note: Avoid adjustments that cause the LED to remain lit for an extended period of time

Hi, I cant get my bas to work with 5.1 only with my front right and front left. what channel should i use? please help


Please rephrase. "5.1" and "only ... front right and front left" are mutually exclusive. Look at manuals.

In general, bass is 'managed' by directing it toward or away from any speaker the user declares to be LARGE or SMALL, usually based on arbitrary cone sizes instead of bass handling capability. There 'managed' bass is rerouted to the presumed capable LFE/Bass/Subwoofer channel to avoid potential damage to bass-shy speakers. Therefore, if one lacks a subwoofer one has to tell that to the receiver and designate the other speakers as LARGE or the bass will get tossed in the bit-bucket

I turned my 15" L7 kicker and smoke started to come out the box


As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)

But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)

Here is a link to your manual for the subwoofer.
http://www.kicker.com/sites/default/files/SoloBaricL7Series.pdf

So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)

Consider yourself lucky if your subwoofer is still working without issues.

5.1 surround sound


Here is how you fix it. Its really easy actually take a look at your Subwoofer 99% of the time you can control two controls for your bass somewhere around the Subwoofer. If you raise the volume of your Subwoofer you'll get more bass. Try it and let me know how this works out for you alright.

Need to know the right setting to apply for my subs


You need to match your amp's input voltage (the gain) to the output voltage supplied via your deck's preouts. Turn you radio up to normal listening level, and turn the amp's gain until you induce audible distortion then back it off slightly. Set the bass boost and crossovers to on and type (highpass for front/rear full range or lowpass for subs).

Bass boost/Gain


Both the bass boost and the gain generally do the same thing, except the bass boost is essentially "additional gain" at a particular frequency (in this case, 45Hz). I would suggest lowering the bass boost (10?) and adjust the gain. Honestly, you may have to play around with both settings until you find a happy medium. There is going to be a maximum the amp can provide no matter how you get there. Hope that helps!

Speaker/sub bass


Hi, it is possible that the sub volume control is worn out. If your particular brand/model uses the rotary/wiper type (variable resistor) then replacing it should do the trick but this involves soldering which be done by an electronics technician or qualified to perform such repairs/replacement. Hope this helps. Cheers.

Crackling Sound From Subwoofer


Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection.  Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.

If the crackling is on the subwoofer only, it might be damaged from bottoming out.  See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.
