Hi, does anyone know what size the jaguar subwoofers that come with the premium audio system are?

I think there are two of them behind the rear seats.

Thanks

 

small, not worth replacing

I just got a alpine 12" with an alpine amp in my trunk. The signal input to my amp comes from the stock subwoofers.
So instead of tearing out my factory soundsystem they just un-wired the stock subs and re wired it to my alpine amp by using a line out converter.

ThenI removed the rear-deck subwoofers soI could hear some more crisp sound from my trunk. It worked great! My stock headunit with the "sub" control now controls how hard my alpine hits.

This was a very nice upgrade

 

oh that sounds really good

 

I did the same thing. I plan on replacing the door speakers too and eventually running them off an amp too.

 

I got my amp and line-out converter done by geeksquad
this cost $120
- $80 amp install
- $19.99 line out install
- $19.99 custom firewall drilling (b.s.)lol
ThenI had to make my subwoofer box and install it so geeksquad didnt over charge me foreasy work.

Sooo worth it!
