One of my rear speakers is blown and I was just going to throw another set of speakers in there. Mine has the Monsoon system and was wondering if they made speaker adapters. I am having trouble finding any.


Here is the plug:




And just to make sure, its a 6 x 9 right?

EDIT: Ended up just buying a replacement speaker. Found it on amazon new for like 55$ shipped.

 

Just cut the plug off and solder the wires on to the new speakers. And yes, they're 6x9.

 

make sure you get the correct ohm speakers.
i think you need something like 4 ohm

 

There is two sets of wires there one set is a low pass for the sub part of the 6x9 and the other is highpass you will have to use the high pass if you want it to sound good at all heres a tech sheet on what the wire colors are
