Question about Infinity BASSLINK Car Subwoofer

1 Answer

LED lights up but! ???

I connected a wire from the remote wire on the head unit (SonyCDX-L600X) and connected it to the Remote on the Basslink and the power on LED lit up, but still no sound from Amp. I turned the Gain back and forth and adjusted the fader to front, center and back, still nothing. I also used RCA splitters as recommended by the owner of the local car audio instalation shop, he said there was no need to splice into the rear speakers and connect them to the speaker level plugs on the Amp, he said just use 2 sets of RCA splitters on the 2 male RCA plugs on the cable coming from the 2 audio out jacks on the head unit and just plug all 4 into the 4 RCA line level input jacks on the Amp and that should be all it takes to get the front and rear speakers into the Amp from just the 2 audio out jacks on the head unit, Well, I did exactly that and still no action???, even tried changing the configuration around, front rear, L/R, nothing, I have no Idea where to go from here. I also noticed a new problem, the right rear speaker channel is very weak even when i go to full rear fader and full right balace, i tested the speaker, it works fine but when i run 2 test leads from the right rear speaker +/- wires directly at the rear of the head unit and connect to a test speaker, the right rear channel is still very weak even at high volume, all other channels are strong. could something have fried that channel. Help with these 2 problems would be greatly appreciated.

Sounds like there is a problem with the amp. Try switching the inputs around for that output on the amp. If that does not help, Yes I would have to say that there is a problem with the amp output circuit.

Infinity Basslink. I wired and connected everything and sounded amazing. I removed my center console to construct a box to put the Basslink in. When I was putting the Basslink sub into the box (tight fit)...

I would get a test light and see if the remote line is still working. Otherwise, yes you probably fried it. Doesn't take much in car audio to fry an amp.

Power light

Hi Bill, I believe the power problem is related to the Remote wire which should be blue or yellow. The remote wire is suppose the turn the Basslink on and off when the radio is turned on and off. The yellow wire is normally used for power antenna. Traditionally the remote wire is blue. You can use a Speaker level adapter and splice in with the L/R rear speaker wires, and the adapter will convert the speaker level to line level. The output of the adapter will go to the Rear speaker input on the basslink., Write back if you need more detail on the adapter.

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


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.

Basslink Powerlight comes on then fades quickly

check to make sure your remote wire is hooked up to your amp turn on that runs straight out of the stereo not your power antenna also make sur you have a clean ground(no paint or rust) and also check your connections make sure you have a strong connection to all wire hook should check to see that your remote wire has no tears in it or small rips or cuts because that can interrupt your current to and from the amp and radio

Power Never Comes on

that remote wire has to be hooked up to the power or the radio power antenna wire which will switch the remote wire on when the radio is turned on, so that remote wire really should be hooked to the radio wire that gets power when the radio is turned on , thats why the sub is not turning on

Infinity Basslink killing battery

Both issues sound like they are related to a non-connected or loosely connected remote wire on the Basslink.

If you're using RCA preamp wires to connect your stereo to the Basslink, make sure the remote wire input on the Basslink is solidly connected to the stereo's remote output.

If you're using the speaker level inputs on the Basslink and not the RCA preamps, make sure the remote input is not connected, as the Basslink will automatically turn on when it senses the speaker level inputs are active.

No power


Other than the +12V, the ground (-) and the 2 RCA inputs, normally external amps have also a remote trigger which switches it to active on. The remote trigger is activated by a wire from the head unit. Colors would either be yellow or blue but depends on manufacturer of head unit. Alternately, you can connect a simple toggle on/off switch to activate the external amp.

Additionally, pls verify that the 2 RCAs from your head unit are audio out and not audio in for aux source.

Good luck and kind regards.
