so i bought a 10 inch sony explode for a little more bass and when i hooked everything up i got a very loud annoying thumping in my sub and in my right rear speaker! all connections and wires look great i checked them 3 times. any ideas??

What deck are you using?


Did it work fine before the sub was hooked up?


What amp are you using?


Do you know sony xplod is garbage?

You would have been better off going with a bottom line kicker or alpine 10. Better sound. Less distortion and a fuckload more durable than the shit voice coils and surrounds that sony uses.



Right now, my money is on a bad ground, bad deck or bad amp. If your power wires are too close to your signal wires, you can also get feedback from that too.

wires are fine, yes sony explodes are garbege(no money! needed more bass!), deck worked fine before adding the subs.

Your getting interference form something..does it do it with your car in accessory mode...meaning with the car off?

Unhook your amp and see if you're still getting it from your mids and highs.

where are the wires routed? did you do it properly and put the power and signal wires a minimum of 3' apart? or are they running right next to each other?
