Question about Car Audio & Video

1 Answer

I was listening to my stereo system in my car and all the sudden all the speakers stopped working and the sub has a constant and quick vibration. I disconnected the sub but the other speakers still aren't working. I have 4 Jl audio speakers and 10 inch w3 Jl audio sub run on a 5 channel 1500 watt amp. What could the problem be?

SOURCE: I hooked up my two 10 inch JL Audio W3v2 2 ohms to

try one at a time. if they work then try hooking them up differently. if none work, then check to see that your amp is not in protect mode. if amp is ok, then check to make sure you have your rcas connected to your amp. in other words, re-check all your wiring. if still nothing, try your amp on your friends car and vise versa.

Why does it play and stop but monitors work fine?


Some subs are switched on and off according to the level of the input signal. The purpose of the switching is to prevent initial "pops" and sub-audible pulsing from damaging the speaker. To the listener, however, it creates the sensation of a sudden loss of hearing followed by restoration.

I have the Klipsch Sub-10 Subwoofer, and it no longer plays music. Now it hums (vibrates constant) and corresponds (louder or softer) with volume control. Light is home but no one home situation. V


Does the subwoofer have the same hum when the input cables have been unplugged? Many input cables use very fine conductors, which often fail. A bad cable will often introduce a hum and prevent a signal from getting through. If the noise is still present without the input cable(s) connected, then repair options are limited. No schematics are available. There's a daughterboard that has been available, but its failure usually causes the system to die (short-circuit). The cost to repair the amplifier may be close to the cost to replace the entire sub.

The subwoofer output on my Kenwood VR-606 has suddenly stopped working. I have tried the "setup" several times, turning the subwoofer off and back on. Also, when I first power up the system, it emits a low...


It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps.
Cheers, Don.

Wierd problem with my subwoofers please help


It sounds like your RCAs are pickin up noise somewhere, are your rca cables next to your amp power wire? this could be the problem. Just recheck your signal wires and make sure they aren't close to any significant power cables. Also does the noise only come from your subs or your car speakers to? If it comes from all your speakers you may have a headunit problem... hope this helps

Subwoofer pushing out problem


it sounds like one channel in your amp had shorted and letting dc go to the speaker...a speaker is an electromagnet and requires ac to make it pulse..the amp has a blown channel and would have to be repaired and a factory service center...there is no quick fix..

Subwoofer noise


You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub
