Speakers,Subs and Stereos

Hi all,I’m getting my Jimny next week off of a mate, and I’ve got the first few bits sorted, wheels, tyres, crank sensor etc. But looking further into the future I want to upgrade the speakers and stereo system. I was wondering if anyone had had any experience with fitting the slim underseat subs, as well as speakers all around. And also if anyone has fitted anything in the way of the new Pioneer SPH-DA120 7” screen with CarPlay if it even fits.
Any help greatly appreciated

I fitted a double din Sony into my 2009 Jimny so it can be done ( SPH-DA120 appears to be double din also), but the vehicle age will determine what bits are required.
What is common across all ages is the poor standard speakers. Uk only gets front speakers, but the factory location for both front and rears speakers limits the size you can fit. If you want the best sound reproduction relocation of the speakers to door cards etc may allow better sizes to be fitted. From memory if you are lucky 5" is as big as you can go in the standard locations, more likely 4inch. The good news is that even though the rear speakers are not fitted they are cabled from the head unit.
If you stick to standard speaker locations your are going to need some form of base unit in my opinion, as you say maybe under seat.
I cant offer any suggestions on this but will read any offered with interest.

Awesome thankyou Mike. Yes I may look into fitting rear speakers also. Looking into the location of the 03 stereo location and the 09 it maybe be too angled down in the 03 to be functional. I may end up getting the new Pioneer SPH-10BT with the smartphone screen. Thanks for your reply!

I have for a very modest outlay got quite a decent system. 4 inch 3 ways in the back, 5.25 inch 4 ways in the front. They required spacer rings and some trimming of the internal structure of the kick plate covers but they are discreet. I also have an underseat sub and a simple single din pioneer in the dash. It's never going to make your ears bleed but it's not bad certainly not for less than the cost of a branded double din touch screen.

I got mostly the same set up as Lambert here.
All original stuff must go. First a 2Din Pioneer AVH 3700 something DAB.
then changed the front set to two way with small tweeters on the dash top, Later changed the bass elements to JBL 5 or 6" mid bass down front.
I cut holes in the kick plates.
Rear sides i bought some cheap but almost OK 4" off ebay.
You should get 5" inside with some work.
And I have a way too cheap ~40£ bass box under the passenger seat.
All helps, but i regret buying all the cheap stuff. Typically me trying to save money but end up throwing it away after a while just to buy better stuff

Only thing I am pleased with is the JBL's and the Pioneer head unit.

In my SJ413 I had a speaker system attached to the rear door. In my Pajero I have a system attached to the roof behind the rear seats.
