Anyone making a direct replacement for the meridian sub that's under the driver's seat? I'm assuming JLR is using this system in a few cars and hoping someone offers a better quality sub as a swap.

 

I managed a car stereo shop right after college and went on to start a business in custom audio, theater rooms, etc. so I might be able to help.

My Defender is still on order and I only had a 3 minute test drive so I didn't even turn the radio on. It's an HSE but I assume it's another middling set-up that I'll have to throw some money at.

What is it you are looking to change about the sound? Distortion? Lack of range, punch, etc?

 

I'm also interested in upgraded the sound system. My vehicle is still in port waiting for rear tail lights but I'm sure my X isn't going to produce the punch my custom JL setup will in my F250. I'm assuming I'll need a bigger amp and would love to fit at least a 10" sub if possible.

 

I'm thinking the same. Tapping the wires into the existing sub to keep the factory controls, adding a 12" sub/amp, and throwing some Dynamat in the doors.

 

Looking for better low end/bass response. I want to feel the bass, not hear it, if you know what I mean. Was hoping there was a simple sub swap available.

 

Yep, unfortunately what's in there is more of a woofer than a subwoofer. Adding a 10" or 12" sub in a box with a dedicated amp would really be the way to get some boom.
