CD Autochanger etc, etc
Discussion
I am just about to fit a cd autochanger. Also, I may fit rear speakers and an amp for the fronts. Anyone got any advice on types of speakers front and rear (I don't want to cut anything!) and where the wires go to reach the back. I have all Kenwood kit. Someone told me about there being a passage down the passenger side from the battery area to the boot for the wires?
The cd looks like it will just fit above the petrol tank which looks pretty simple (bolt or velcro best?)
What about earthing the Amp? I was thinking about putting it under the passenger seat?
Any assistance would be greatly appreciated.
Thanks.

Someone smart ar5e will always ask what you want sounds in a TVR for 
but that doesn’t answer your question so here goes:- Rear speakers are I would say essential and I suggest you fit an amp to drive these rather than the fronts, maybe you are going to fit an amp for both? Regards speakers types it seems the most popular solution is to fit a decent pair of 6x9’s but I wouldn’t want to advise on make, I have Pioneer which most people seem to say are crap, although they sound fine to me, others seem to recommend Infinity. If your car doesn’t already have rear speakers I doubt TVR will have pre-wired it for them 
so you will have to feed some cables to the boot, especially if you decide to fit an amp, also of course you will be feeding wires through for the CD stacker in any case so do it all in one hit. If you carefully peel away the carpet on the passenger side footwell you will find a hole in the side panel at the bottom through which the wiring loom runs. If you look behind the door shut face you will see that the carpet there is only held on with Velcro, this allows access to the door catch solenoid and also allows you to get the wires from front to rear through the passenger side sill. You may need to be imaginative about how you feed the wires through; I used one of my lads old fishing rods and some sticky tape etc. Basically you need something about 3-4 feet long, which is strong but flexible. Once you have all the cables through the sill you can run them over the rear wheel arch and inside the boot, if you pull away the grey carpet you will find they emerge near the fuel filler pipe! It’s obvious once you start! Regards the CD stacker mine is indeed just on top of the tank held on with a few SHORT screws into the back panel, don’t drill into the tank for heavens sake! You will also find that the passenger side speaker may foul the filler pipe depending on how large the magnet is and how deep the speaker is so you may need a 2 cm spacer. Regards the amp I have a 100w job in the boot alongside the CD stacker, seems to work ok, regards an earth, well why not run a cable back up the sill (do it all at once) and earth directly onto the battery terminal? Good luck, Rich…

Good luck, Rich…Rich - Thanks for that. Are the rear speakers mounted in the panel where the vents are ? In which case I need to get the jigsaw out - worrying! Also, do you need to move the vents somewhere else? I read something about the boot blowing off if you do not have vents? Probably just TVR pub talk.
Many thanks for any more help you can give. I would rather do the job than trust my local stereo shop. They did my Elise (sorry - I did have one before I got a proper car!) and there were screws rolling around on the floor afterwards! Thanks again - DM

David - yes the rear speakers are mounted in the rear upright bulkhead which as you say involves cutting the fibre-glass but don't worry, it's not structural as the body is mounted on that steel chassis! Needless to say use the template provided in the box with your speakers before you start cutting and as they say "measure twice and cut once"! I found that a jig-saw with a fine toothed blade went through quite easily, remember to remove the gray carpet from inside the boot before you cut, it forms a sort of double panel. Oh and finally... be very carful to check that your blade is not too long and can't touch the fuel filler pipe. Other than that mark up and cut away! Rich...
Oh I forgot to mention, I don't have the vents and as the speakers were installed by TVR at birth, I guess they can't be that important. Easiest would be to install the speakers, leave off the vent and see if there is any noticeable effect... on what I am not sure? Suffocating cats in the boot perhaps? see…

My Griff has factory fitted (I think) pioneer speakers where the vents would have been.
The speakers sit in plastic mounts about half an inch thick. Holes have been drilled into the non visible half (i.e. the underside) of these to retain the venting from the cabin through to the boot.
Its a neater solution than putting a whole new vent in - and from memory it is referred to in the Griff/Chimaera bible...

Yes my speakers have spacers and these do have holes in them but I assume they were just there rather than there being any intention by the factory to drill them there! If you see what I mean. Certainly the instalation I did in my S3c didn;t have vents and I can't see why you'd need them? R...
I have the original pioneer speakers fitted in the front and some nice Pioneer where the vents used to be (slightly larger holes now). CD Changer as you say fits nicely ontop of the petrol tank.
Sounds super, although the two natural sounds at the back have their moments.

Boot blowing off? Sounds unlikely. The vent would be to vent the cabin into the boot, not vice versa. Maybe the roof might blow off .
As I've said before, your are lucky indeed if your TVR is watertight, let alone airtight. The vents are superfluous; my car has had speakers fitted for 4 years where the vents were, with no ill effects (other than a ringing in the ears!!!).

'The best sounds come from the two rear external speakers, volume controlled by the right foot.'
Definitely. Both my Griffs (4.0 and 500) came with CD autochangers fitted - I tried one once just to make sure it worked (total pain because I was constantly having to adjust volume depending on road speed) then dismantled as much as I could of both and put them in a box in the spare bedroom!
Fitting positions: 4.0 (retrofit): Nakamichi power amp - centrally above fuel tank in boot. Clarion CD autochanger to right of it. Rockford Fosgate speakers in each door, plus little round tweeters above. 'Pininfarnia' woofer on parcel shelf - to decaptiate occupants in event of crash!
500 (factory fit): CD autochanger vertically behind passenger seat - and bolted through to underneath of car! I tried removing it but gave up! The head unit leaves a nice hole so I made an open fronted aluminium box the same size, covered it with black fablon and it's a handy place for sunglasses etc.
