Asked by May 06, 2012 at 08:24 PM about the 1996 Honda Civic DX

Question type: General

My Sub's not working... it turns off when bass is mid to max but runs fine with low volume... i had the electrician check it and he
said there's no problem with the connections so far its just a sensor that cuts the power when in high volume to save the circuit
from frying... i have a capacitor and this is the first time the sub is doing this. it never happened before... they say i have to
change my head unit because its the stock one for a civic (fujitsu) or i have to remove the dash to check for cuts especially on the
blue "remote" wire that was actually spliced with the subwoofer wire set for the box. everything seems to be fine except for the
sub going on and off so i cant really play loud music... what else did i miss?

the sensor is inside the NBN sub... how come it's happening now when i bught this unit 5 months ago it was working fine and it isnt switching off on high volume and high vibrations?

check for voltages when its working fine, and the conditions that cause it to fail it sounds just like the wiring is too small, or it has a poor connection, try to remove the cap and see what happens

what kind of subs are you using and what kind of amplifier are you using? you may have the gain set too high

NBN 500W bazooka type, Generic 700W dual channel amp.. Pioneer 220W separates.. i dont think i set it too high, besides the setting is on "filter", not "gain".. i checked the sub and the board is fine, even the audio out connected behind the stock head unit has no problems with the wiring.

and i bought an audio wiring set and i had a professional install it for me, he ran all the wires behind the door, under the floor to the side of the seatbelt mechanism and under the rear bucket seats, then leads to the trunk.. i also bought a capacitor for it..

couldnt find the problem here either...

either nobody on this thread has any type of car audio experience or you guys have been misled for way way too long... First of all he means capacitor in the power wire for surge stabilization when the bass hits. in more recent years capacitors have proven to be a waste of money. second the gain on the amplifier is it separate from the filter cross over switch. game would be the amount of signal into the amplifier for it to amplify in the filters which will determine if its a high pass or low pass basically a subwoofer or mids and high amplifier. sounds to me like your game is too high or you have the bass on your head unit turned up. When running external amplifiers you should always have your trouble and especially base at 0 anything more than that will be putting a distorted signal into your amplifier and most amplifiers are designed to protect themselves from this. try keeping the base at zero on your head unit and then it just in games appropriately with your volume turned all the way up until the Sun clips and then back it out just a little. otherwise you've got a voltage and amperage problem and are not getting enough power to the amplifier for it to run at those volumes. hope this helps...
