Hope the link works - shows the replacement of my rear loudspeakers.

Thanks Chris [].....but the link is for smaller speakers. Im looking to fit 6X9's that according to the Infinity blurb need 81mm depth....guess I'll just have to remove the existing speakers and measure what space there is

Jacob, which 6 X 9 Infinities did you manage to sqeeze in the back? I've been offered some Infinity Kappa 693.5i and will take these if they'll fit.

PS. How do I quote a previous post[]

Martin, I opted for the Infinity reference 9613i I reckon that they would be a very similar size to the Kappa 693.5i - check out ininty's website for all the specs.

Look at the top right hand corner of each post and you should see 3 icons. Reply, Quote and forward. click quote and that will appear in the main body of your new post

Forget 6x9s in the rear shelf, they need air movement to breath properly, There is insufficent depth under the shelf, making the fitting tricky but mainly not allowing the speaker to breath properly [] The air will just "bounce" straight back up into the cone again and can cause phasing distortion and sound "flat". Imagine if the same speakers were fitted in a rear shelf of say a standard hatchback of some sort, the boot area will be the "box" for the speakers and give a good mid-bass response. You wouldn't believe the difference, thats why half decent door speakers can work well cause the door is effectively the speaker "box".
Best advise is get the small bass tube (made for 911's) and stick it behind the passenger seat[]
Cheers

That makes sense Alex, I'll look out for a decent active tube and stick with good quality smaller speakers in the rear shelf and doors.

Thanks for all the usefull feedback[]

I've replaced the front 5.25 main door speakers with new 'Fly' ones and fitted a new Blaupunkt head unit but the system is lacking in any base response at the front. I still have the original crossovers and separate tweeters in place. Is replacing the crossovers likely to make any significant difference to the 'bottom end' sound?

At the moment the majority of any base originates from the rear speakers. While trying to resolve the problem I also notice the speakers are all connected under the drivers seat in what looks like another amplifier, but this does not appear to be connected to the head unit is this likely to be limiting the front base response.

Regards...JB

If you have an Amplifier in circuit with the speakers and you can here audio then the head unit must be connected to it somehow, and probably, if its Blaupunkt, via a din lead of some description. Nowadays all manufacturers use phono connections.
Re your question about the crossover all that does is split the "lower" frequency band to the "bigger" speaker and the "upper" frequency band to the smaller speaker[] It does not extend the lower bass response. To do that you need a larger cone diameter and more power. For what its worth there is a direct relationship between the the dia. of the driver a distance of the wave length of the lowest frequency you want to acheive.[8|]
Trust me the bigger the better. Not always poss. tho'[]
Good luck

Hello again
I've just remembered, if the "phasing" of the speakers are incorrect, it will give you poor bass, no stereo imagery and s**t sound.
Check that out, i.e.all the "positives" of the speakers are connected correctly.
If you have any detailed questions please e-mail me[]

Can anyone recommend a good fitter for all this technology? I live in West London so someone local or who visits would be ideal.

Theres a good place over in Hillingdon, near Uxbridge. They've been there since B.C. called S.K.Radio. Tel 01895.238592
Good luck.

Signor, thanks for the tip.

Just thought I'd give an update:

Last night I fitted a pair of Infinity Kappa 6.5" two way jobbies and the difference is stunning! Apart from the improvement in bass response, the imaging is infinately better (excuse the pun[]) and the sound soooo much better throughout the range.
Fitting was relatively easy with no cutting of metal required, just the holes in te door cards that needed opening out. This set up will do for me now and I wont be bothering with a bass tube.

Cheers,
Martin.
