Infinity BASSLINK Car Subwoofer - Answered Questions & Fixed issues

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 there an existing sub in the car .

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.

what are you talking about unit01, you talk too much but isn't revealing the main prob. it's the Electronic board that is deffective that's why it's turned on, but no sound, because the board of the sub is not operating anymore, maybe a busted capacitor or IC. that's why. ok? don't listen to unit01, it's a non sense talks lol

Check the fuse in your car's fuse panel. If it is burnt then change. If it is still good, check the fuse on the head unit and amp.

Run the ground back to the battery. The body is not a good enough conductor.

The issue is most likely a short in the amp internal circutry where power is essentially flowing without resistance acrosss the short. You may or may not have sound or crackling noise as it depends on where the short is.

If you are electronically inclined, I suggest the folliowing:

- disconnect all power and open the amp up
- look for any burn marks around the circut board and parts.
- first focus in on the area where the power comes in - see if any diodes (black cylinders with stripes on them) are burnt / cracked
- next have a look at all the MOSFETS. These should be 3-legged components and will likely be mounted to the shell or heatsink. Look for any burn marks or cracks on these.
- also look for any wire or component that may be shorting other components. Generally all wires should have shielding and all components should be soldered firmly. Anything crossing other components could be a problem.

If you find any burnt/cracked components, they will need to be replaced.

Here is a sample image showing the MOSFET chips to the top and bottom on the aluminum rail.

Hi,

Does the servo led stay on? If so, you might have a fractured solder joint. Inspect the switch control PCB for fractured solder joints and check the Positive and Negative 15v outputs on the same board.

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.

check your amps ground wire i had similar prob the vibration from engine caused the wire to move interupting the current

Hope this solves your problem. Thanks for using FixYa.

i think you dindt but the remote right were it suppose to

If the sub already has an enclosure, (box) put some legs on it and enjoy! If no enclosure, you will need to find out what size and type of box you want, go to a car audio dealer. I have replaced my home speakers with car speakers, MAKE SURE YOU KEEP THE OHM RATIMG THE SAME!!!!!!!!!!!!!!!!

Simple as it sounds, try Home Depot/Lowe's! They will have them! Been there, done that!

Sad to say but this usually happens when one of the capacitors go bad or something else internally. Most of the time it's cheaper to get them fixed, but I have seen them get up there too! Hope this helps some.

go to the website that built the part. they usually have manuls you can download and get exact part number.. then go to ebay or google t for fix andddd parts cosr

if it has a short some where in the lines it will do that

remote wire hooked up also?
