Sub wont hit

This is the scotter stereo thing again. ok so the deck and speakers all work great now. but now the sub wont hit. I feel it vibrating but it just isnt doing anything. i have the amp turned up all the way and the sub section turned up all the way on the deck. it is a bridged sub therefore i have wires running from both terminals on both sides of the sub and then the wires from the amp connected properly. also i have the amp side wires of the sub connected to the L+ and the R-

the subwoofer is a c4 x-10 i had to put it under another product because its not an option

Appreciate again the "Ask Me".

Appreciate the "FixYa" rating you have given me here. sub wont hit - moz-screenshot.jpgA request if I may, my being able to assist you is largely dependent on my standing (rating and raking) on the site. Since the Panasonic has been successfully dealt with, perhaps you can re-evaluate and rate the following as you see them fit:

Many thanks in advance. As to your current concern, the 400watt bridged amp:
  • if the Panasonic was wired reversely, might it be possible that the sub amp was likewise wired reversely and therefore suffered similar electronic failure?
  • most high power amps have a built-in DC to DC power supply other than the external 12VDC, these would often fail if reverse power is delivered even just once;
  • since it is heating, then it is actively drawing power. that would mean that (if it is wired correctly), the SMPS (switch mode DC to DC power supply) might have a problem. Often culprits may include:
  1. capacitor;
  2. regulator;
  3. diode;
  4. or any of the other components.
Further diagnosis leading to a repair would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron. Or perhaps you may again seek the assistance of whoever worked on the Panasonic.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

My 10" subwoofer is hitting hard but no vibration, why? please help me to fix this issue.

It sounds like your crossover point is too high ie: 100Hz and up can cause vocals to come through.

Or you are having "crosstalk" between channels.

My 10" subwoofer is hitting hard but no vibration, why? please help me to fix this issue.

You need a low pass crossover set at 80 hz & below. It will stop the music you hear in the sub. Don't expect the feel of a single 10 in a room to be like the same sub in a car. A car fills with pressure & gives the feel you want. A ported box designed to work with your sub will give you 3db or more output than a sealed box.

Red Power Protector light

Hi, the only way i can see the amp resets the stereo is that power is dropping. The amp should have its own wires directly to power/battery so as to not affect anything else.

On the protect, try to disconnet all the speakers, make sure the power is OK. If it appears to work, the there could be a problem with speakers/cables. Try a different speaker to see if it works. If the problem continues with speakers off, a different speaker etc, then there is a problem with the amp. Hope that helps

My deck doesnt not transmit signal to my amp. Is this an rca cable problem

Hi Your problem is almost defenetly that one speaker is hooked up with reversed polarities, making one speaker cancel out some vibrations of the other speaker. So get the wiring phase checked again, its ethier this or a fauly cable. Good luck.
