I was kinda thinking since 2004 TL has it's own Sub output..
how about get another amp and wire directly to the sub line and get a more powerful sub.

Any one knows if this gonna work? or blow my fuse.

 

You already have a sub, as you know. The first thing I'd try is to simply replace the existing speaker with a more powerful and efficient one. It might be enough!

 

I don't think the factory amp has enough power to run aftermarket subs

 

Many aftermarket drivers will me more efficient than the stock one, and put out more sound with the same amount of power.

Just becasuse they handle more, doesn't mean they NEED more power to work. Check the efficiency rating on the drivers. This is specified at xdB out with xWatts of power in. You will find that some, like the Cerwin-Vega drivers can be VERY efficient.

Otherwise, you will probably need to run a new DC power liine to the rear, since the sub amp draws most of the power in an audio system.

 

Thanks....... r u willing to change the sub too?
If u do so.. tell me.. if it's good or not hehe...

 

Why in the name of god would any adult want more sub?
