Sorry guys just messing.

No go on rear speakers, plays with the staging of the sound, no need for rear fills, save the money for those rear speakers and get some better fronts, and if u really want rear fills then I would amp the front speakers and run the rears off the deck,

Single sub and some powered 5.25 or 6.5's comps is the way to go, more power you push on the sub, a good amount for the tops will need also, a little overpowered will give some nice headroom and then tune the tops so that the sound from them doesn't over do the sub output, for a nice balance in mid/tops to bass output.

I'm not a fan of 6x9's period

I hate 6x9's, to me it just doesn't seem right to have a non round speaker, its just wrong, I cant really have any front speakers as i have no where to put them, so it is going to have to be a set of 6.5 that i already have and my sub that will be cappable of much more than i will ever want.

It amazes me that someone with little to no experience in professional car audio stystems, has the nerve to call someone with Ruckus' experience advice, 'opinion' - I've done a LOT of reading due to studying for an honours degree in sound engineering, and EVERYTHING I've read says exactly what Ruckus is saying.
I've done four Mini installs now for various people, and spent a LONG time getting each one perfect, there's a huge difference between 'oh, that sounds okay' and a GOOD sounding system, not even great!
It's obvious, if your speakers are mounted correctly in the parcel shelf (not that you can ever call it correct) then the boot will be 100% sealed. How on earth do you expect the sound waves to make their way into the cabin of the vehicle - thats not bass you can hear/feel, thats the seat back being hit by high pressure sound waves, punch your boot board - it'll sound simmilar, it's basically just low frequency panel resonation that you can hear!

Not only that, but you know those sound waves hitting the seat back? Well, thats hitting your speakers at the same pressure. Hit your speakers with a force of one newton 30 times a second (1800 per minute) expect them to last long? And even if you don't think it's doing much damage to your speakers, think of the extra power that fighting against that force is sapping from your system - see that 200 watt rms speaker you have? While, fighting against a sub, you might aswell just make that about 50...

If you're going to keep the speakers where they are, please, put a sealing strip under the parcel shelf speakers (you'll get better sound from a speaker who's rear is operating in completely different air to the front of them. Place them in bowls or boxes, stuffed with lambs wool and wrapped on the outside in flashing tape to reduce vibration...

As for porting into the car, Drill as many holes through the parcel shelf (not into the speaker bowls) and if you've got no rear seats in the car, as many through there as possible.
When making a subwoofer box, it's important to 'tune' the speaker box to a specific frequency through porting the box... but then the boot essentially becomes a second speaker box, which would also need tuned... it's easier to tune the boot by cutting the holes to allow ALL the air to flow into the cabin... how? 15 inch sub? Well, you'll need a total of 15" of holes through to the cabin to get ALL the sound waves through.

Again though, you'll still suffer from the dreaded resonance! How to solve this? Just soundproof the car! Or at the very least, the main panels, and the bootlid...
Beleive it or not, it isn't the quality of your speakers that gives you the best sound, yes, they help, but the preparation of the car is what gives the best quality!





See? Fully soundproofed! Speakers are also fully sealed from front to back, so no air from behind the speakers will reach the front, simple. I can push 105db, and apart from the bass that finds it's way out through the windows, you cant hear a thing! Will post up a vid showing this tommorow!

My system goes against all this, 4 3 way speakers, two in the shelf, 2 under the seat, why? Because I used parts I had... I could of done it much better, but my car is on a very tight budget! Dont even have a sub, but I will when I have money, it'll all be changed as soon as my engine conversion is done, it sounds horrible atm!

Want a good sounding system? Soundproof the car, 6 inch components up front, move the tweeters on a peice of blutac to where they sound best, experiment, but have the speakers infront of you, can be in the middle of the dash, or one either side! and some sort of small sub set up in the back - even just a 12 built into a pod on the rear arch, or mounted into the seat back, pointing into the inside of the cab with the driver into the boot in a sealed, tuned box. Ideally, dont have anything in the parcel shelf, or under the seat? Why would you want the sound pointing towards the bottom of your seat, or your rear window? But just prepare everything well and it will sound good!

Even cheap speakers can sound good prepared well! So guys, just listen to someone with as much experience as Ruckus - you drive cars because you enjoy it, its a hobby - therefore you know how to drive well, and know a lot about your car? Ruckus enjoys working with car audio, even on a professional basis, he knows a hell of a lot more than you. At the end of the day, even if you guys are happy with the sound, it's damaging your speakers, and wasting power - you could half the volume that you need to listen to if mounted in the dashboard!

Rant over!

For a start if that is aimed at me i haven't once said ruckus' knowledge is opinion, it makes complete sense, I am doing my install on a budget just using what i have lying around, this means i am not going to be going out to buy a shed load of sound deadening, i may go out and buy some just for the boot. I haven't really got anywhere to mount speakers up front so as i said earlier they will be on the parcel shelf in sealed units, you mention using lambs wool inside of the enclosure? what do you do loosely pack it in there or get as much in as possible?, where would i be looking to get some from aswell? cheers

I've just seen this!

I don't think it was aimed at you dolly, if you read the thread back it's others that clearly think they know better. You are listening and acting...

[RossKnight]

Dolly, can't you purchase speaker pods for under the dash rail?

These in 6.5" will only set you back £30 from Optimize Automotive

It is only my ratty looking project while i finish my proper project so dont really want to spend money on anything haha, i will have a go at making something myself maybe if it will sound that much better

It was just the way it has been worded, at times it seemed like it was aimed at me

No no, dont worry Dolly, not aimed at anyone in particular really, especially not you - You made it clear that you understood everything, it wasn't necessarily just this thread either - I've seen in quite a few threads now, people ASKING and then IGNORING advice from people who know a LOT better! Not you, as yours was nothing to do with positioning or anything, you only asked how to stop a rattle. You accepted and presumably followed the advice given, just the others, as I said, not just in this thread, in many others.

i found out it was the boot floor rattling on the subframe so a peice of wood wedged in there and it was fine oh and some holes into the cabin
