6X9'S under back seats
#1
Posted 14 November 2005 - 09:16 PM
Im preparing up my floor pans in my mayfair and whilst doing so have made wooden templates to cover up under the seats to fix up a set of 6x9 speakers. Ive done this before, but what im wanting to know is, has anyone done this and is it worthwhile running the 6x9's through an amp or do you run them direct from the head unit. I already have infinity 16.5cm speakers on the back shelf and they sound fine direct from the head unit. I dont want more bass, just louder and clearer sound. What does everyone recon?
ps i currently have a 640 watt amp which has allt he usually things like high pass filters, low...etc and its in good working nick.
thanks

Then ditch the 6x9s, and any speakers behind you
Make some simple pods to house some 6.5" components in front of you, and amp them - job done!

you wont get bass reflex from 6x9s - especially in a sealed area. Bass reflex is when you have a sub in a tuned box, with a port. The bass relex is what makes it louder at one specific frequency??? ive made wooden boards that i can fit my 6 x 9's into and seal it all up so its working a bass reflex action. Ive also got padding...etc to dissipate air slightly so it sounds cushioned bass rather than a bang. Still want to know whether its worth having an amp in there to get more power as they are literally on the floor.
padding is only any real use in a sub box - if used correctly, you can make the sub "think" that it's in a box 1/3 bigger. In a box with 6xshites, it wont do anything - except act as a water trap, and rust your car a little quicker
are they worth getting an amp for?
only if you dont want SQ, and just loud musical noise
and pods will only rattle if they're poorly made (especially those pathetic plastic ones you can buy) - I was referring to custom-made fibreglass pods on the inner-arch. Similar to philsters ones, but smaller :wink:
get some decent 6.5" components up-front (50w rms is plenty) and running off a 50w rms/channel amp (I mean REAL rms, not "peak" *******) For comparison, a HU is about 50W PEAK, which only means around 20w rms. Imagine it being 3 times louder than a HU, with the clarity of a decent home stereo, and you're almost there
Sorry to shoot you down, but thats just the way it is

Mount the 6x9s under the rear seats on a speaker board. Because they are a low level, The high notes will be deadened out by the backs of the seats etc. So they will give a mild sub affect.
Ditch the shelf speakers, and bring them to the front. YOu sit in the front! Why spend your money in the back!
If you dont already have a dashboard. Get yourself one. I can run up a dash of your requirements from MDF, carpeted in grey / blue / red for a sensible price. :cheese:
(I made my dashboard)

Anyway, Mount the speakers on the dashboard, directly infront of you. Either mount them in the air vent holes (Removing the vents). OR Move your clocks to the center, and mount the speakers direct infront of the seats (Like my setup)
Along with the 6x9s under the seats. This will provide a good sounding setup. And because the front speakers are so close to yourself, you wont have to turn it up as loud to hear it, and so the music will be clearer too.
Hope this helps.

parcel shelf without cutting horrible holes the bespoke pods actually enhance
the mid & bass and do not vibrate !!!!!!

have made them to look great as well ,from behind look like rear headrests
can be painted or covered .
eddie payne
these are fixed on a solid bit of MDF and sound the part as they are at shoulder level in the car not tucked out the way..

I think the word you're looking for isnt SQ - it's tonality :wink:Ive fitted a set of 6x9's under my backseats and am thoroughly impressed with the sound quality. I dont run them through an amp - just from the head unit and volume is never an issue.
They might "sound" good, but you wont be getting real SQ, as you may as well just have a mono speaker behind you
The best explanation I've heard recently, is on here:

it's a bit of a read, but you'll have a better understanding of what SQ actually is afterwards

As for sounding alright it depends what you have to compare it to, when i first fitted 6x9's to my mini i thought they sounded awsome, they were really loud and would rattle my mirrors.
However at the time no-one else i knew really had anything better, then we went to the custom car show at doncaster and listened to a couple of cars there, the difference was astounding and i promptly ditched the 6x9's fittied a 12" sub and some door builds.
Then all my mates were really impressed with how much better mine sounded (then most of them ditched the 6x9's fro a decent set up front and a sub).
After running it for a couple of years on this setup i heard a system which had been setup for SQ (not spl), when you sat in the drivers seat the sound was truly amasing (and all still with a pair of comps and a sub).
After talking to the guy for a while i realised that equipment is only the start of a great install, i was always out to impress my mates with more stuff, bigger speakers etc and then i'd bang em in the car as quick as i could without any real thought as to positioning.
Now i don't pretend to have the best system in the world (far from it) but i belive that with the equipment i have it would be difficult to achive a better sound (without losing the back seats).
If you are happy with what you have then thats fine, when you hear something better you'll realise how much could be improved (and hopefully learn from that).
