Installing aftermarket rear speakers

[Christian H]

I have been meaning to do this for such a long time and am only now getting round to it

I'm not interested in sacrificing space for amp's and mega sized speakers I just want a reasonable sound to listen to.

I changed the standard Nokia dash speakers a couple of months ago and fitted some 4" Alpines which have improved things quite a bit(also fitted a Sony head unit)
I now want to fit speakers into the rear storage compartment.

My question is what size are the factory speakers? space does look pretty tight but was hoping to fit two 3,1/2" speakers in each side.
Has anybody fitted their own aftermarket speakers and if so what size did you use?
And how did it turn out?

Thanks in advance for any advice

I think I read somewhere rear speaker where 3.5 inch..

good luck with your project

IIRC, if you have the OEM rear speakers you will need to modify (cut) the steel mounting plate as drivers used were not std 3.5". The Harvey PNP aftermkt kit did accept 3.5" drivers w/o any issues though.

Good luck

Here are my steps

-I put the bag back into the car, hid the wires and reattached the bag.

I have a JVC head unit and currently have the stock door/dash speakers. I use the fader to have more of the sound coming from the front because the sensitivity of the rear is so much better than the stock speakers. I have new speakers coming in for the dash and door over the next few days so it will sound better.

Thanks for the input guys, after a little bit of searching I found these pics



It looks pretty straightforward so I will make my own mounting plates and source some 3.5" speakers from ebay will post pics when done if anyone is interested.

Although if it all goes wrong and doesn't work I shall deny all knowledge of this thread and destroy all evidence I ever tried

[Christian H]

Ok guys it didn't turn out too bad at all so thought I would share with you.
Firstly I removed the storage unit from behind the seats.


I then removed the "cubbyholes" these are fixed with 3 torx screws but also hot glued at the front, remove the glued area carefully to prevent damage to the thin plastic edge.





I then made some templates from 3mm ply I had lying around to mount the 3.5" speakers I bought from ebay for £57 quite reasonable I thought!




Then I covered the mounts with some alcantara I had left over from previous interior mods I carried out



One side in place



And now in position in the car




Sorry for the iphone quality pics, not sure whether to purchase the speaker grills yet as they cost more then the speakers, but will give it a factory look.

Just got to wire them in this weekend and job done, not bad for less then £60!

Might do the doors now

Looks great, well done! How will you wire them in, are they capable of running at 2 ohms?

I just installed the kit from Suncoast. Install was about 5 hours. Results are...meh. Not sure the new sound is worth the $325.

Thanks for the honest evaluation! Saved me some money.

[mikesz]

are the rear shelf speakers wired in series or parallel? Planning on doing this upgrade as a DIY project and wonder which would provide better sound. Based on my understanding wiring them in parallel sounds like the better idea. I would probably add an amp for those 4 rear speakers also.

I'm interested in this too. I'd most likely buy some 8 ohm speakers and wire them in parallel.

It's going to depend on the speakers and amp. How you wire will depend on what impedance are you shooting for.

I installed my Pioneer 3 1/2" speakers today, the stock ones were crumbling. I used the original plastic mount by enlarging the openings a little bit with a dremel but not too much. The sound is excellent now! The speakers are wired in parallel.






I also replaced the door speakers with 6 1/2" speakers(http://986forum.com/forums/general-discussions/49796-found-6-5-speakers-fit-door-without-mods.html) and replaced the dash speakers(Dash Speaker Replacement) All pioneer. A big thanks to all of those who have posted on here in the various threads that I used

I got mine installed in the "engine cover". Great sound.
Got a 3 way DLS system with basses in the doors, 4 speakers at the front, and 2 in the back.

As an update, I was not happy with the look of the modified OEM bracket so I sent an email to Euro Motorspeed concerning the brackets they include in their kit. I ended up talking to Toi and ordered just the brackets. I wish I had done that in the first place! The brackets are of excellent quality and fit the 3.5" Pioneers perfectly. Even though no one ever sees the modified brackets, I knew what they looked like and it bothered me. I know, I have issues The brackets cost $65 shipped and IMO are worth every penny considering you would not have to spend the time to modify the OEM plastic brackets. The Euro ones are metal and are a perfect fit.

Bruce,
Thanks for the info on the brackets. They are nicer than stock, and certainly nicer than MDF! I am going with Panasonic all around also. I am even going to try out a Panasonic under seat sub woofer from a Subaru Impreza

I'm looking at that sub as well
Let me know how it works for you
