Sorry again to redo an old thread, but there seems to be much more choice available for 17cm (6.5? inch) speakers than for 16cms. Which ones fit without hassle?

Also has anyone got any idea of mounting depth, as the ones I've been looking at all seem to be around 65mm.

Finally what's the difference between the normal and 'custom' fit speakers? Will I need an adapter or to make an mdf surround if I go for the normal fit type?

Any help appreciated.

On the pre face lift cars, it's really easy to fit uprated speakers, generally 16.5cm 6 1/2 are the norm, get some Vauxhall Corsa plastic adaptor rings from Halfords £14.99 or something like that, saves the hassle of making mdf spacers up (Audio G Man posted this a few weeks ago) they basically fit straight onto the door on the original mounts, the speaker then attatches to the spacers and put it this way my speakers are 72mm deep, the door skin goes over the speaker fine plus it doesnt foul up my windows either

Custom fit speakers are usually better than the normal ones, they have much bigger woofer cones / magnets enabling them to handle a lot more power, my original Addzest speakers could handle a whopping 20w of power peak lol my Rockies can handle 250w peak....

On the other hand, generally speaking most of the good manufacturers make 6" speakers anyway, and then there's no chance of any problems! 6" is the standard for Jap cars (and I believe used to be the standard for American ones too) so they are about. Kenwood, etc. I don't think do the 6" size though - they seem to leave them to the more "specialist" manufacturers.

The Corsa spacers don't actually just fit on to the door - you need to extend the existing holes out in the appropriate directions a bit with a drill. It does then fit in the end but the screws end up pulling it very tight so you need to get these new holes fairly accurate. Easier than MDF though. Also you lose the drip guards that are on the back of the original spacers. I rigged up something in place of this but it is still more messing about. I was hoping my 17cms (6 1/2") would fit the original spacer but they were not even close to going in - mounting depth was only 60mm - the diameter was the problems. Infinity 605cs seem to be about the biggest that literally drop in and even these don't fit the New Age WRX IIRC.

Just to chime in, on how to make the speakers sound as good as possible tip, there's an awful lot to be said for MDF. Well, sort of.

Having made quite a few door builds for different cars (Necromax - back me up here ) it makes a huge difference if you can make a cabinet for the door speakers. In the same way that back-pressure helps/makes a sub run properly, the same goes for the mid-range drivers in the front. Fortunately though, you don't have to go nuts with the size, like you do with subs

All I'm doing on my Legacy, is to build a cylinder no longer than the driver with magnet, and bolting that to the door. End result, a proper resonance chamber for the speaker, and no loss of sound into the door. This has the added benefit that you don't have to put layers of dynamat/brown bread into the door panels if you don't want to
