many amplifiers protect against a short and against an open. They are looking for speaker resistance within limits. Your wire to the speaker may be too long or too thin. You may have hooked up more than 1 speaker per output causing too low resistance. Keep your wires short as possible and use 12 or larger gauge wire if you are driving large wattage speakers. Check the ohm rating on your speakers and compare them with what the amplifier calls for. Hope this helps

Recommendations for replacement 6 inch speakers with the Jensen AWM 968? They are for my rv, and are the only speakers in it. Thanks in advance for any help!


In-car entertainment systems, especially the types chosen for camper vans, etc., are often capable of quite high power outputs and usually need speakers capable of being driven at those high power outputs without damage.

The trouble is, such speakers usually don't sound so good at the very low volume settings needed for evening and late night use in a campsite environment to avoid annoyance to neighbours.

It is a big problem choosing speakers that sound good at low volume and yet can withstand the higher volume needed to overcome the wind and road noise of driving. There have been many technological advances in speaker design and a hi-fi specialist will undoubtedly be able to make suitable recommendations that are resistant to damp conditions, long-lasting and with cones free enough for good reproduction at ultra low volumes but robust enough to withstand high power outputs and such drive units are likely to be fairly expensive.

For myself I would choose to use a dual speaker system with a multi-speaker system comprising several low-powered speakers strategically placed for low volume use and a fairly standard high-powered system for normal use and a selector switch.

Speaker at low volume and can't increase


How are you connected? , if were less, try with a cable and first of all use high quality audio, no bad recorded stuff and full batteries . it should be doing it . if none of the connection modes offers a higher volume, then it's the unit.
greeting, Richard

Subwoofer makes noise like an untuned TV regardless of volume knob


I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

Sub static at low volume fine at high volume


Prob always there just can't hear it at higher volumes. Check the grounds of the amps an the Caps if you have them. Then check the preamp wires from the head unti to the amp. Keep it as shielded from power wires as you can. Some times tying a ground from the amp back to the head unit ground can fix a hiss or static

Stereo volume goes up itself


Funny huh? Actually, some aftermarket radios like Pioneer have a setting where it senses cabin volume and ups the radio volume itself to overcome cabin noise. I doubt this is your problem and belive the unit is really "mental" and needs repair/replace...

Sub woofer volume adjustment


The gain dial is not a volume control. The gain dial is used to compensate the output level of your car radio head unit. all car stereo units output are not alike. If you set this gain level too high, it will cause major distortion (clipping) to the audio output of you speakers when cranked up. This excessive distortion WILL eventually, or even quickly damage or blow your speakers.

I personally blown speakers this way no not properly setting this. (lesson learned, I guess :| )

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.
