You may have a ground loop issue. Make sure your ground lead is as short as possible (<1ft, if possible) and that it is mounted to a nice, clean (unpainted) spot on the vehicle. If you have multiple amps, try and ground them to the same point.

Bridge two 12inch subs together


it depends. what is the ohm rating of each sub, and the amp. are the subs DVC(dual voice coil)? and are you trying to bridge them directly to the amp? i need more info, but i can say that if they are 4ohm subs, if you run them parallel, they will become 2 ohm. to keep them at 4 ohms, they need to be run i n series, and you need more than 2 for that.

Rockford sub squeaks


Hello markwasicki,

You did not specify what type of enclosure the subs are in or if they share the same airspace. But the sound you describe sounds suspiciously like the enclosure is at fault and not the sub itself.

Remove and reverse the subs in the box and test for the noise again. If the noise is still produced on the same side of the box, it's the enclosure. If the noise follows the sub, then you have a problem with that sub.

If the box is making the noise, and it's a ported box, you probably have "port noise". If it's a sealed enclosure, you could have either an air leak or flexing noise. In either case, repair the enclosure or put the subs in a new one. If the sub itself is making the noise, there probably isn't much you can do. Most likely some part of the voice coil assembly is touching where it should not.

Hope this helps.

Can the sony xplod 1000watt amp be bridged for more power to just one sub? also what problem would cause a subwoofer to make a slight burp noise whenever the car is shut off or into the non accessory...


Hello,
This amplifier can only be bridged for a single subwoofer with an output rating of 380 watts bridged. The amp is not rated for 1000 watts.
The burping noise you here is the electronic switch discharging power off on the large capacitor that are used in high performance amplifiers. Regards, rcampsr

High Pitch Noise Coming Out Of My Subs?


sounds like it could be a warning sound that indicates either a short or a bad connection and is tripping the safety warning. check all speaker terminal connections and connections on the amp to make sure there is nothing loose or touching

High pitched noise comin from sub


if sound also goes away when throttle is released and sound returns when throttle is pressed down, then you have engine noise from car engine electronics. In older cars, this was quite noticeable when the cars had distributor caps. The electrical noise caused by arcing required for the spark plugs could be your issue. It is resolved with a noise filter which gets wired inline leading to your in-dash deck and power amp (if you have one). The filter can be found many places including Radio Shack and Crutchfield.com. First find your total wattage draw for each component of the sound system (deck and amplifier), then divide by 12 to get current draw through filter. Purchase that size filter or larger.
