Installing aftermarket rear speakers

[Christian H]

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

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?

awesome. was looking to do something like that too. tell me how they sound once wired. do you have to insulate them or pad in the back? please keep us updated on your progress.

Sam this is the first time I have tried adding extra speakers etc in a car so any advice would be helpful, my Sony head unit has a speaker impedance of 4-8 ohms with a maximum power output of 52 watts x4 at 4 ohms.

The speakers are 150watts peak 20 watts rms and 4 ohms

So do I wire the rear speakers in series or parallel?

Am I right in thinking wiring the speakers in series would lower the impedance too much for my head unit?

Will they work better in parallel?

Help!

I thought this was too easy

This should help you decide, it's a good read:

Looks like I got that the wrong way round!

So if I wire two 4 ohms speakers in series it will equate to 8 ohms my head unit can handle between 4-8 ohms.

Thanks Sam

Somebody stop me if it sounds like this is all going to end in tears........please!

Not sure if I will bother insulating will see how it sounds without first. I will update once up and running.

I wired the speakers up today in series, I used bullet connectors under the storage unit noting the left and right side wires for ease of removal when accessing the engine cover.

The sound is so much better now with the rear speakers filling behind my head with sound,

I don't think it will be necessary to insulate behind them as the speakers are mounted on carpet and the compartment they are in is

also carpeted and it sounds fine to me.

Very pleased

wow. awesome. you have inspired me to attempt this too. any pointers?

3mm ply fit in nicely? and where did you get the carpet for the ply?
