The two storage boxes behind seats are empty,one has a plastic liner,the other is material,with a stiffer lid that clicks into position.

Does this mean it had factory sub at some time?

There is no wiring in there either.

Is the factory sub a viable and easy fit,as I have access to one for free with upgrade speaker in it,or am I creating more work than necessary.

The speakers all appear to have been updated,but it needs a little bit of a lift

My other option is a small underseat sub,but would prefer if it was just in the storage box.

Any help or advice would be greatly appreciated.

Cheers
