Question about Car Audio & Video

1 Answer

Hi, My Sub has stopped responding the light is not turning on so I assume there may be a fuse inside the sub which has blown. I have taken out the speaker and foam filler, taken out the screws for the back panel but cannot get the unit out the back of the box and am scared to push too hard. Is it siliconed in? Should I just push harder? Thanks Ryan

SOURCE: subwoofer works at high volume, doesnt work at low volume

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.

SOURCE: Sub is blowing fuses!! :(

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.

Sub Speaker giving intermittent loud crackling and sharp loud popping sounds even with main volume control turned off. Crackling sound can be reduced by turning sub volume control off.


It may be the control itself too. In time, these controls can get dust build up inside it. There are volume control spray cleaners available from Radio Shack or other electronic parts stores. The cheat on cleaning the control is to just rotate it from stop to stop as many times as it takes to clear the noise.

Why does my MCS sub 10 not turn on?


Is that the right part number, MCS 10, and not MCS100?

The MCS systems use a basic sub which is matched to the satellites. There's very few controls other than level on the MCS100. So as long as the power light is illuminated the there's very little other than the volume control that could be set wrong on the sub. So what it comes down to is either

  1. a blown fuse (no power at all at the sub);
  2. a broken input (#1 cable, #2 sub input socket, #3 blown sub plate amp);
  3. incorrect connection at the receiver end or the wrong settings

As a quick test, unplug the sub cab from the amplifier/receiver end. Switch on the sub and turn the volume down all the way. Briefly put your finger across to short the RCA/phono tip and ring. The sub should make a buzzing sound. You now know that the sub is working and the cable appears to be okay

Switch off the sub and reconnect the phono/RCA to the sub out socket on the receiver. You now know it is connected correctly.

Go in to the receiver's menu and check the speaker settings. Is subwoofer present? Yes/No

Are the satellites all set to Small? (they should be with this system)

Are you playing a 5.1 source in DD or DTS to ensure that the sub gets a signal? Play a BD or DVD.

On the speaker balances, is the sub channel set to 0dB?

As long as all the above is set as listed, then the only things stopping the sub working would then be insufficient volume at the sub's Vol control (so increase it), or an intermittent cable connection (wiggle the cable), or a broken subwoofer out signal at the receiver.

How to fix blown sub (replace fuses etc)...? stop protective light illuminitating?


The first thing to try is to disconnect the sub and all speakers from the amp's output block. The only things that you need connected to the amp are the 12V power, the ground wire, and the remote wire to turn it on. If the protection light comes on with only these three wires connected - your amp has been damaged internally and will either need to be repaired or replaced.
