Question Regarding Changing Rear Subs

Post by RustyZ4 » Tue Dec 03, 2019 2:35 pm

Hi All

I have changed all my speakers except the two subs behind the seats (the ones in the rear bulkhead) which I was going to change to the Audison plug and play speakers, my question is, after looking I cant seem see how you access them, the grill on the front doesn't seem to be removable or am I missing something, so is it a case of accessing them through the rear panel in the boot?

If it becomes a large job to do, I might looking at putting a single one in the ski hatch instead.

Many thanks in advance for any help

Question Regarding Changing Rear Subs

The two subs are screwed from the front into captive nuts set in the steel rear bulkhead that are sealed enclosures..

To get to them you have to take the rear carpeted area out or back enough to get your driver/fingers/subs in

To get the carpet to move you need to remove the two rear speakers, the two rear top plastic trims hiding the top seat belt d ring, remove the d rings, the rear buklhead trim, the roll over hoop trim and the top trim covering the rear central speaker, the 4 luggage cinch brackets and the boot fold over cover and the rear boot cover rear plastic trim..

TIS info covers it all..its a big job, bigger than replacing all the other speakers put together,,figure on 2 lots of prayers trying to prise things apart like the rear roll over covers..
