    Same damn problem, Infinity repair center out here says it's the main board that needs replacing (I'm looking at mine right now, just took it all apart), and that's as much as a new Basslink. This is a horrible product that sounded decent for the year or so that it worked. This does not help Infinity's reputation.

    Same problem here. Bought unit used, should have listened to it work first. Power light comes on, but no sound. Believe me, I've checked every possible connection including every combination of speaker input and pre-amp (rca jack) inputs. I would like to know if this is a common problem with this unit.

    I loved this thing in my Jeep Wrangler for the year or so it worked. No changes were made to my system and it stopped working. I am a electronic technician and know that ... with verified input ....either line level of speaker level ......there is no output. The amp is shot. Was looking to buy another of the same for replacement but not after what I am seeing about all the problems with this thing.

    I had the same problem. Mine turned out to be two fried resistors, numbers R143 and R144. They are 3.3K Ohm, 0.5W, +/- 5% resistors. I identified them because one end of each f them looked corroded and rusted. I checked them with a multimeter, and they had infinite resistance, i.e. were blown. I just got the new resistors at Radioshack and soldered them in. Now, it works fine! Your problem might not be the same as mine, but once you get the amp off to look at the board, just look for things that look wrong and replace them. It's not the most direct way to go about the repair, but when parts cost a couple bucks each, why not at least try your hand at it?

Basslink works for a few seconds after i turn on the stereo, then it fades away. The servo light is always on even when i disconnect the input line and turn the knobs to the min level. What could be wrong?


Hello, check the +15v and -15v on the Switching Power Supply Control board. If one or both are missing, it is probably Q117 for +15v and Q118 for -15v. If one is missing the limit comparator will rail to one side and cause the auto variable volume control to trip the servo protection.

Servo light


You have an internal problem in the amplifier of the sub woofer box. You need to take it in to be checked at a service center, there are no quick fixes for them. Sorry,

Basslink has no output, but Power LED and Servo LED always on.


Hi,

One or more of the DC to DC outputs might be bad. Check the
/- 54v on the main PCB and the /-15v on the switching controller PCB.
Losing one side of the 15v will cause the limit comparator to rail and force the servo protection, even with no input signal.

Is the light on the infinity basslink suppose to be red or green


Hello jmw3031,

The Basslink should have both a red power LED and a green servo LED. The red LED should be on when power is applied. The green servo LED should only come on during high-level bass transients. Turn the gain down slightly if it stays on for extended periods.

Hope this helps.
