Title: Help with my zero knowledge on car audio
Post by: AJ_EQ on 07 April 2011, 12:56
Just bought my mk4 and so far I love it.  The only problem is the parcel shelf has two massive gaping holes in it....
In the future Id like to put a stealth shelf in and keep the oem look.
For now though I have just bought a couple of JBL 6 x 9 to fill the holes.  I would like to link them up to the oem headunit, but I have no clue how to do this.  I already have rear passenger speakers and didnt know how this would affect the setup.

Any help would much appreciated.

You will need an amp to power the 6x9's in the shelf.

And if you still have the standard VW head unit that's going to be difficult. Ideally you need to pick up a new headunit that has a pre-out to run an amp. Either that or buy a parcel shelf without holes in and sell the speakers you just bought.

hmmm.  My girlfriend runs 6 x 9's (came with her car) just with a jvc headunit.
Ideally I'd like to keep the oem look in the front, but if its not possible to run the 6 x 9's off it, I have a kenwood unit in my corrado I could steal.

Also she has clips between the 6 x 9 wiring and the wiring to the HU.  Any idea where I could get these?
Just means I can whip out the parcel shelf when I need to put my Mtb in the back.

You don't need an amp just disconnect the rear speakers and use the cabling for them.

thank you, exactly what I need.  Is it missions to get the wiring out of the rear speakers?  Will standard HU beable to power 6 x 9's?

what power are the 6x9s? standard manufacturer cabling is a bit sh!te imo, but will do the job fine, as mentioned, an amp will do a much better job and make the 6x9s more clearer, just to add, parcel shelves are flimsy and may break from the weight on them

It doesn't matter what power the speakers are. It's the amp that defines the current load on the cable.

The HU will put out the same watts whether a 10w or 1000w speaker are attached.

Output of hu will be between 10-30w rms.

lol tbh Id rather not have the 6 x9's at all and keep a nice clean parcel shelf.  But atm cant afford to spend money on a new parcel shelf so will make to with current one for time being.

took rear door cards out, which was fun being a 3 door.  I managed not to break anything  :wink:

Spliced the cables together and bam sounds a lot better than those standard rear speakers even without amp, though I couldnt get the tweeter in the door cards to work.... oh well..  no problem i have some of those amazing 3-way 6 x 9's...not...

Maybe in the future I will drop some new speakers in the front. 

If I was to consider putting new speakers in the back again in the future.  Would it be better to drop them the oem holes in the rear door card or stealth shelf them?

Im not a massive fan of having amps taking up boot space.... hmmm maybe a small might fit in that first aid/warning triangle place  :huh:

Don't connect standard tweeters to aftermarket speakers. You'll alter the impedance the internal amp of the hu sees. Either running it under impedance which could low it or over impedance which will prevent it from running at it's rated power.

Your 6x9s have built in tweeters.

Just connect the 6x9s to the two cables coming from the front of the car.

There's loads of places to hide amps in the mk3. Have a look at project 150db.

Very interesting, intrigued to know what you guna do with the rear door card/amp.... Now Ive taken the speakers out of there, there is ample space.... for an amp :grin:  Maybe a future project for me.

ergh.... Both my door cards are now back on, with the tweeters still clipped in...  Do reckon this will be alright, there not working and I really cant be arsed to take the panel off again.

Leave them in there just unplugged. In my first attempt I had a different component amp. I bonded wood to the outer panel and attached the amp to that. You need to be careful of the size of amp to refit the panel. Mine was a bit big lol.

Under seats, front footwell, roof, spare wheel well. All options.

Moreover, cable clips 6 x 9 and the wiring of the UH. Any idea where I could get this?

Lol wtf is this.  I did try and type a message from my username, with some similar words like this... strange...

Just wanted to ask if you can get a female/male clip that I can put on my 6 x 9 cable, so I can quickly remove parcel shelf, when I want to chuck my bike in the back?

The speakers should have male spades on the terminals. A big and little per speaker. Just get the same size female spades from halfords, etc

Plug and play voila.
