A good book for you to read would be "The loudspeaker design cook book" It was written by the chap who founderred the company Wharfdale many moons ago. Some of it is pretty heavy reading and you really need a degree to understand it, but some of the tips are very relevant. For example, if you were to take out one of your speakers in your boot and just hold it by the magnet in free air, when you gave it a signal, all you would hear is trebble, even if it is a woofer. The reason being that to create a positive soundwave from the front of a speaker, an equal and opposite soundwave is made from the rear of the speaker. Now these soundwaves cancel each other out if they can meet, so any with a wavelength greater that the shortest distance from rear to front of the speaker, will therefore be cancelled out only leaving the trebble! So the enclosure design is of massive importance to the sound! Porting a speaker cabinet will reinforce the bass provided the cabinet is manufactured correctly. Bass is none directional and trebble is directional, which is why cheap home cimema systems can get away with tweeters as surround speakers and one bass woofer to deal with all the bass from all 5 channels… So having tweeters as part of a three way speaker pointing into the boot is pointless really and will sound muffled. I'm affraid your system, although it may give you the effect that you want, is really really wrong..  

Sorry…

Not taking the mick.. I am trying to help. If you want to know more try the book I suggested or I think even Maplin do some simplified books. A company called "Wilmslow Audio" in Leicester are a great source of advice and info. They once sent me a basic grid formula for calculating the inductors and capacitors needed to make passive crossovers at different frequencies.

Another thing, if you are driving so many speakers with a couple of large amps, try a 1 Farrad capacitor as a power reservoir to feed the amps…

Hope this helps!

Juz - you should lightly sand the glass on each of the led dash bulbs to make the light spread out more and give you a much brighter dash!

No need, I bought frosted LED's

Walt thanks for the advice but you seem to have missed the 2X 6*9s and the 2X6" 3 way speakers that are in my parcel shelf and the picture does not show the 6*4s in the front door cards, the Tweeters on my Roll bar or the 6" speakers in the rear cards.
Whilst I appreciate what you are saying, the two professional in car audio specialists who I discussed my plans with and who have seen it since both like it and think the sound Quality is very good. Believe you me there is no muffling or reduction in any range of frequency.
Many ppl  have listened to the system (with the roof up and down) inside and out and whilst the system CAN be very loud inside the car there is little outside noise this was to be my first intention on this build as I don't want to inflict my taste in music on other ppl all the time.

You may also notice that all the wires go through specifically placed holes which go into a cavity created behind the rear seat oh yes and guess what is there a 1 farad capacitor which I did not find pleasing to the eye and also I felt took up to much space in the visible install.

For total purists my biggest "mistake" was wiring the earths of the amps into a chain BUT as this also assisted me with my desire of a semi reduced  output I did it but may be altering it later.

So my apologies if I have caused offense Walt but you can ask Foxymk1  about the sound as he has witnessed it himself.

You have caused me no offence matey.. I am just trying to help. I have built several thousand pound car stereo's in my time and learned quilte a lot in the process. My friend Chris did a similar system to the one you have there. He had so many speakers in there that we couldn't even wind the windows down. Quantity is easy, quality is not. A car is not an audio friendly environment in the first place, so to have loads of speakers all doing different things is only going to make things more difficult! I wasn't taking the mick, you obviously want your stereo to sound as good as possible, I was only trying to help. To explain my point a little, take a seriously expensive set of hi fi speakers, try looking up naim sbl loudspeakers for example. they only have two drivers per speaker and all the effort and clever design went into the cabinet design.. I doubt you will ever find a highly acclaimed set of speakers with zillions of drivers all over the cabinet pointing in all directions! Like I say, I am not trying to take the mick, only help you understand how to improve it and why!  

I'm very impressed..but also interested by Walt's comments - as with most things, there's a lot to know, even on speaker installations!

But what do you do with luggage??? - Silly question I know…but on my daily driver tintop I've gone the other way and made a stealth shelf for a pair of 6x9's which lifts them out of the boot space…I often have a lot of stuff to carry, and found I couldn't even spare the space of them projecting into the boot. I now have them in a wedge shaped rear shelf mounting in mdf covered in black carpet, which means the boot is free for junk, (including guitars!). Also means the parcel shelf can be removed easily, unlike the silly original fitting to the rear seat back!

and i bet all those speakers are ….kin heavy!!!  8O

craig is right about inflicting his taste in music on other poeple, because it is crap!

as for his system, it so sounds nice

oldfart I have a wife with a car for for lugging around luggage and stuff
lol

Good point…I guess Mrs CabbyCraig knows her place!
Mrs Oldfarts' car just failed it's MOT on rust to the floor pan…Sh*t! Only a bit of welding needed, but annoying all the same. Lucky I've got some boot space after all!

Favourties mods which have been done on both my mk2 and sa mk1, grey leather interior, gearstick cut down slighty to give a short shift feel and blue leds in clocks and switches, and steering wheel replaced, clean, not over the top mods in my eyes
Pete :wink:

i trip which is connected to another cigarette lighter behind my VDO's then the ipod connection comes out into the bin below the steering wheel.
