Highly recommended the sound deadening. The rear 1/4 are massive cavities, thinking back should have maybe doubled up on the deadening in the big panel (small strips) to really control the panel.
We where looking at getting some focal speakers for the car, but the jbl amp is a pain with it running separate channels for the tweeters. I think I posted the ohms for the speakers also, as there isn't much information floating around. If you do replace your rear speakers, I might be interested in grabbing them as a friend of my dad's has an rcz with a blown rear speaker so I might look to help her out and replace it with yours.
Highly highly recommended grabbing those trim clips from China, soo much cheaper than from Peugeot!
I've been trying to find out where people have been running the amp wire to the battery through the firewall but with no luck... I never actually saw this thread when I searched...
Sorry I can't remember that we'll the clearance for the speaker, but they are riveted in place from the factory.
You might find it just easier to replace the factory amp.
