My advice is to not bother with 6x9's. When I was younger I worked in halfords and they had an audio section where the sound specialist worked, and this guy knew his stuff. Anyway, he recons they are a complete waste of time because of where the sound is pointed (i.e at the roof). If your looking for bass to fill the sound out a bit get a small sub or bass box - thats what this guy said to me. I was real against the idea of a sub but once I heard the difference I knew I had to have one.
If you change the 6x9s it will sound great. I have had a full ICE install in mine, new head unit, speakers all round and an amp, and it feels like there is a sub in the back, but I havent lost my boot.
Generally it is really hard to get a decent 6x9 cause most speaker manufactures don't see it as a proper speaker, cause the type of sound that is created from them and how they are designed. Thats why you very rarely see any above £150.
The ones I went for are InPhase 6x9s, and they are stunning. Like I said it feels like there is a sub in the back, they are supposed to be the best 6x9s out there, especially for the money. But you need to amp them up. The best advice is for you to first choose your head unit, then look at speakers. Cause if you just keep your standard head unit with different speakers it wont make any difference, probably be worse in fact.
Best thing for you to do, depending on how much you wanna spend, is go to a reputable car audio shop in your area. Somewhere that does show cars generally means its good. Dont bother with halfords or bass junkies, they dont know too much about they quality of the kit. I used Car Audio Centre. If you do get any big 6x9s fitted then you will also want to think about havin some Dynamat fitted too, cause it will stop any panel rattle, which believe me you will get (mine go mental at full volume) and it will make it sound even better!
I am replacing my rear 6X9's with some that are dedicated subs. Their frequency response is 35hz-350hz. I plan on putting a 1 channel amp (300W @ 4ohm) in one of the cubbies in the boot.
Dynamat and seal mounting of course
Actually, high quality fronts, with enough power to drive them, are all that is really necessary for fantastic sound. I have not finished the rear speaker/amp install yet, so my opinion is based only on what I have heard in others cars.
The rears will be only doing only what a boot box sub would do.
in fact I am using the sub output from my HU. It has a seperate level crontrol to set its volume.
music is in stereo, so that's 2 channels: right and left
u don't want more than one speaker playing the same channel and frequency...therefore, u don't want rears
in a car, u want 2 good fronts (strong component set: adire, crystal, focal, jl xrs, dynaudio, rainbow, etc) and a sub
if u wanna save boot space, then you get 2 good fronts and 2 6x9s that are made for sub usage, are sealed (build box under bottom of speakers, are sound deadened (use b-quiet, not dynamat) and are xovered to only play lower frequencies (set somewhere around 60-100hz)...u'll then have good audio, although I have trepidations about 6x9s being anywhere near as good as a 10" sub
As i said mount the 6x9 subs in the cubby holes in the boot (they will just about fit) then none of the mid range sound is lost from the normal back speakers. Plus your rear passangers will be happie that way. I'll let you know when I do mine.
I've tried 6x9 subs with the xover controlled from the head unit and they go only a little
deeper than quality 6.5 components in the doors. I now have a 10" JL sub and it is a
true sub. Sorry but 6x9's don't cut it if you can spare the boot space. If you can't give
up boot space spend your money on an external amp to power the fronts rather than
spend it on 6x9's.
