My first cd player was a sony cdx 6020 (?). I thought it was pretty good as far as how it sounded & its features, but it did break down a few times & now the display is fully buggered. I have heard of similar reliability problems with sony gear.
My only experience with sony speakers is the explodes which are amped & still sound sh*t.
Brayden, I am not implying that your system isn't good though. - Just that I wont spend money again on sony to find out. There are just too many other good brands worth trying. I have had very good experience with kenwood gear, and heard even better things about alpine.

As for bridging etc, I'm not too clued up on that at all so I guess I'll take your advise & avoid that on my budget.

I am now pretty comfortable in the idea of getting some 6x9's for the back and some smaller mids for the front. It has got to be a 1000% better than my current setup.

Thanks for the help guys.

No worries and no offence taken. I wouldn't go back to Sony either, I'm more than happy with my current Clarion/Fusion system. :D

Brayden, we'll have to pilfer the laboratory mics and the boss's laptop from work sometime and run a bit of pink noise through your system and tune it properly! :)

Mmmmm.... Pink noise....
Image

Just a note to back up / support what brayden mentioned earlier in one of his posts. - I got some 5 x 7's and mounted them behind the seats in the seatbelt tensioner panel & they rattle the absolute sh*t out of the tesioners. Sounds awfull. Absolutely no way that they can stay there... :-(

So I am now searching for another location for my speakers. Just gotta think of a good spot behind the seats somewhere as I have some 4"ers for the doors.
So I guess I need a boxed solution, but I dont want a box in the way(that's where the dog rides).

Any ideas? :(

how about mounting some nice custom boxes into the corner so that they are facing on a 45 degree angle out of the corner... i reckon that would look pretty phat

*lol* Justify to clarify for those of you who don't know...

Pink-noise is an artificially generated signal used for diagnostics in professional audio. To the untrained ear it sounds 'static', or White-noise, but there is a very important difference. White-noise serves as a useful constant in the context of scientific research, because every frequency present posesses an equal amount of energy.

...which isn't such a great thing in the context of audio, because as the frequency increases, so does the amount of energy present, and thereby the amplitude. We have a hearing range of 20Hz to 20KHz, so just imagine that for any given volume at 200Hz, a sound at 400Hz would be twice as loud, and a sound at 800Hz twice the volume of 400Hz and so it snowballs from there.

So White-noise is useless to us for sounding out a system because it doesn't accurately represent how the human ear perceives sound. Along comes Pink-noise, an artificially generated signal that features equal energy per octave, rather than equal energy per frequency. What this means is that the total energy output for a pitch range of 200Hz - 400Hz will be exactly the same as the total energy output for a pitch range of 400Hz to 800Hz - which is exactly how the human ear perceives sound.


SO, when I've finished piecing together a kit tailoured for these sorts of diagnostic purposes, I want to head around to Brayden's place and run a whole heap of Pink-noise through his car stereo and monitor the frequency spectrum through a matched pair of laboratory microphones and EQ the unit accordingly.

I'm nearly there...


Fritz, I'm convinced that the sacrifice of leg space for a good set of speaker pods is worth it. Don't waste time mounting speakers behind you - your ears will always be forward-facing, mate... ;)

Dunno about yours, but my ears poke out the sides of my head... :D

Seriously though, I have heard some of the arguments regarding having speakers in front of you and not behind, but I have a set of 4"ers, 5" splits, and the 5x7's that will be accomadated in my beastie. So I guess some of them will be in the doors and dash (tweeters), but I would have thought a good balance would probably mean that some of them will end up behind me.

I'm not a massive fan of speaker pods for doors, but I take your point about them being a good position for sound. Bah! - all too hard...

Haw haw haw... And primarily reflect sound from in front of you into the ear canal... Ahyuck! :roll:

That's a... uhh... 'quirky'... combination. :|

Just bear in mind that not many cinemas, concert halls or live music events feature forward facing speakers behind the audience. There's a reason for that. :wink:

No, they're a better speaker position for sound reproduction. The ideal position would somewhere around where the corners of the dashboard meet the A-Pillar... If you were willing to engineer it... :)

Quirky yes.
I was only going to have the 5x7's & the 4"ers (back and front as planned for my 4ch head unit), but then I stumbled across a really good deal on the splits, so I got them as I have a spare 2ch amp sitting there.
Haw haw haw... And primarily reflect sound from in front of you into the ear canal... Ahyuck!
But sound coming in from the side doesn't need to reflect. It goes straight in. - just try clicking your fingers next to yourself & then in front. Next to no difference.

You're presuming that the speakers are going to be forward facing. Where they are right now, they're sideways facing.
Granted live music usually comes from the front. I guess it would be pretty damn odd if it came from the oppisite direction of where you're looking.
Most cinemas (home or real) I've been in have had sound in front and behind where I sat.
I guess the real test of what is good in car sound is to see what the car audio geeks use. I suspect most of their setups feature sound from behind the driver - and not just subs.

Oh well, I'll just have to experiment I guess?... :(

Next to no difference?! Maybe to your set of ears!

You missed my point, which was that you're going to achieve the best stereo spread by having speakers in front and to either side of you, facing you. The best setup I've seen for this to date in any MightyBoy is door pods.

Sounds like the speakers fitted to my MightyBoy when I got it. It's so that you luggage is entertained while your transport it, right? :wink:

fritz wrote:Most cinemas (home or real) I've been in have had sound in front and behind where I sat.
But the rear speakers are there for 'surround' effects only. You'll find that the majority (if not all) of the musical content of the film will come through the stereo pair up front. I don't recall you mentioning that you were fitting a DVD player with a 5.1 output to your ute just yet... :)

If only it were true! The thing I hate about car audio is that because it's in cars, suddenly every wog and his cousins are f##king experts on psychoacoustic theory and EQing. You need to the find the RIGHT geek. Someone who's actually about quality of audio reproduction and no just how many sick subwoofers he can cram into his P.O.S. Commonbore or how man dB he can crank out at the next sound-off.

LOL You're so easy to wind up Josh... :lol: :boxing:

I did notice that you skirted around the fact that probably 100% of cars that win audio comps (not loudness comps either) have speakers other than subs in the back.

Allow to repeat myself in saying that the thing I hate about car audio is that every wog and his cousin is a f*#king expert in what is 'good' and 'sick'.
