Twin 6" or 8" Subs

[Alex]

Some guy's in the US are talking about slotting twin 6" or at a push 8" subs into the stock sub area....so that the boot floor is still usable. Any one on the list done this?

[Flipfinger]

Where does the stock sub sit, as a side interest?

Anyone got a pic of it?

I was going to make a custom parcel shelf and put a big 15" sub in it, but this sounds a better idea, if you can still get to the space saver easy enough etc.

I'll still make the parcel shelf - for security.

[Alex]

Just use a blind to cover it...saves weight!

I'll see if I can find the picture

My blind has some 'worrying' stains on it (not guilty).  Surely a Supra is too small to sh*g in?

[Alex]

Here is a pic so you can see the location but you'll have to dig around in your own boot to work out how it's done....they're twin JL 6" subs

I think the passenger front seat of a aerotop is the only place its possible to get any action....and the bonnet is too weak....actually with the boot open and seats folded down...hmmm...nah not possible!

[Flipfinger]

Pic loads some rubbish Tripod page - argh!

Can you attach it to a post please?

PITA

Is that ok for you sir!

[Flipfinger]

I thank you.  Is that right up by the rear seat?

I need to make some kind of decision this week, I've got a few hundred quid lying around, and I'm torn between new exhaust or some subs and a nice amp so my 5ive CDs sound better...

[Andy Metcalfe]

Mmmmmm..............5ive!!(get a grip!!)
I am also at the stage where i am researching the best way to get some serious lows into my treasured chariot-and the best idea i can come up with is a removeable enclosure that is not gonna fill the whole boot and still be manageable to remove with little effort in the event of needing to get to that horrid bike tyre under the boot floor!!
I am currently looking at a pair of 8`sCerwin Vega`s mounted in a 5th order bandpass box,these should definetly "kick ass" and still not take up alot of space in that "all too small"boot!!

[Flipfinger]

Okay, so the 5ive comment was a joke.....hehe

Let me know how you get on - I too need a removable enclosure (obviously) and Cerwin Vega! speakers are lovely.....I want to do a similar thing really, maybe get one of those dual sub boxes with the nice perspex and angle the subs together...

[Andy Metcalfe]

Will do!
failing that it`s just gonna be a plain old box with 3 12`s firing at the back window using "Vega`s" again but this is gonna take up alot more space and alot more amp to power them!!
Love the idea with the 8`s though and is gonna be alot smaller and also have been speaking to a ice dealer that has made one for a customer already and was very impressed with results!

[FaithStalker]

so how do you get at the sub then????
do you have to remove the rear seats?

[Alex]

Which sub do you mean? The standard one?

[FaithStalker]

aye

No....

[Flipfinger]

Hmm.......likelihood of Mark ever selling his Supra to someone on this list now??

hehe

[Mark Ayling]

And before anyone lowers the tone, they're black leather seats not "cream" ones.....

:biggrin:

Not me, but I know someone who managed it an an MG Midget, if you remember those. If you can work out how they did it, keep it to yourself, I don't need that mental picture. :)

[Ash]

2 years ago I fitted 2x JL Audio 8" subs in a custom fibreglass housing that takes the place of the stock housing. It sounds quite good, considering the limitations of the assembly. Early next year, though, I'm going to rip the whole lot out and replace the rear seats with some *decent* speakers.

What's the wing on that car?  Never seen one like that before (I don't think).  Apologies for diverting the thread somewhat, but I don't know how (or if) I can move this to another bit of the bbs . . .

[Alex]

Its a Rod Millen Motorsport design or RMM to everyone else.

Paul whiffin makes an exact copy for half the price. It comes with either a firbreglass or a carbon wing....

Apology accepted for diverting the thread

[Flipfinger]

Getting back on-thread, I want one of these dual 8in sub jobbies:

https://secure.caraudiodirect.com/shop/acatalog/rbp1082.jpg

£270 for the enclosure

2 x £67.99 for the subs

2 channel Pioneer amplifier £144.99

= £550.97

Gulp.  Before fitting!  And the bloody carpeting won't match will it!

My question is, if my subs are running from an amp, but my front, rear and tweeters aren't running off an amplifier, will the sound be extremely unlevel?

[Andy Metcalfe]

Well Mr flipfinger check this out!:-
                                                     £199 times 2 for CV 8`s
                                         under   £10 3/4 MDF
                                                     £0.00 your own time to make box
                                          Total=£499.98+Amp
Not cheap i know! but we should be able to compare the performance of each of the enclosures at the next big meet............and mines gonna kick your ass!!!!
P.S. you can limit the output by using the gain on your amp to try not to drown everything out with your sub!

[Flipfinger]

If I could make a box half as good as the one in the picture, I'd do it.

My DIY skills are terrible.

[Andy Metcalfe]

Not to worry my friend-i shall make notes of time and material used and i`m sure we can come to some arrangement over your requirements!
P.S. I might add that that i am a qualified carpenter!!!

[Flipfinger]

You know, it's posts like the last one on this thread that make me glad I found this place :)

Cheers!

I notice no one has taken me up on my orange crate design for mounting a pair of 6 x 9's in the boot :biggrin:




Dean..

Just a bit to classy for our mediochre tastes Dean.

[Ash]

It was the light tone of the wood that put me off. Given a lick of creosote I'd be sorely tempted.

Yours,

Dean-you truly are a craftsman and the orange crate is a work of art !
Wonder if MFI would be interested in a man with your obvious talent??

Better of with water soluble Ash, Creosote affects the sound quality.

[Matt Harwood]

Noticing that these posts are quite old now, has anyone had any success in making one of these dual enclosures?

- With the exception of the orange crate -   :)

[Andy Metcalfe]

Matt,
Not me mate!-All good intentions of building something beautiful,even found a supplier with some cheap mac`daddy 12"s and a proper 1200 watt rms amp(absolute peach) and then the day i was gonna go and pick up my new toys the gaffers at work announced that we were all on a months notice and the place was gonna shut!(doh!!)so i decided that my priorities had to change and i couldn`t warrant spending shitloads of wedge on a monster system for my much loved motor!!!!
Hence the fact that i`m on-line while everybody else works for a living!!

[Matt Harwood]

I know this sounds daft but bear with me...

I'm in the car audio and security business so, as and when you do want to put something in, let me know and I'm sure I can do you a better deal than anybody else could.

Excuse my ignorance on the subject of audio for the Supra. I've been in the trade for 9 years now and in that time we've never done any speaker work on a mk 4 Supra. I have no idea what goes in them. I've only had my car about 2 weeks and the only thing I've done to date is pull it apart to fit a security system... Next comes the audio...

It's a bit embassasing working in the car audio trade and having to ask other people what fits but I hoped others on here could give me an insight to plan a system before I start pulling it apart.

As I said, when you do want something let me know and I'll see what I can do.

Matt.

[Flipfinger]

I think it's quite easy, but the guy who overhauled my stereo and car alarm was superb with a Supra, I think he's done one before and they are extremely helpful, Ipswich Car Audio (http://www.ipswichcarradios.co.uk)

Paul might be able to help.

[GordonT]

Say, where do you get those little 6" subs????.....

[Matt Harwood]

Quite a few companys do 6" subs now. I would personally recommend JL audio 6w0. They generally sell for around £70 ish. each. 2nd choice Vibe. Both can handle a fair amount of power for their size, and are very musical.
Focal do a 5" woofer that sounds superb. We've fitted them into the standard enclosures in MR2's with fantastic results... However I would'nt like to say what they'd be like in a larger car.

[GordonT]

Thanks Matt, Ill go looking for them. I am thinking of fitting them in the rear enclosures and dropping an autochanger into the stock Sub bay.
...

[Matt Harwood]

Forgive me if I'm stating the obvious but remember they'll need a crossover to work properly or else they'll sound horribly muddy...

If your running an aftermarket amp, chances are, it'll have crossovers built in.

As I said, apologies if you are aware of this but i speak to people all day that don't know what a crossover or filter is.

I like thet idea about the changer position.... Food for thought...

[Branners]

oh oh oh, me me me, Im one of those people, I have no idea what those things are...I only chose the JVC head unit cos it goes full black face....

JB

[Matt Harwood]

A crossover is something that filters the correct frequencies to the correct speakers.

Low frequency (Bass) to subs and bass drivers
Mid range to your "normal" speakers (doors)
high frequency goes to the tweeters

You may find your headunit or amp has HP and/or LP (High pass and Low pass) filters built in.

If so, using them correctly is very beneficial. Selecting HP will reduce the bass that the "normal" speakers cannot produce allowing them to reproduce a better quality output and reach higher volumes with less distortion
Using the LP in conjunction with a sub will only allow specific bass frequencies to the woofer again resulting in much better output.

Make sense?

[GordonT]

Yep, I know about crossovers, but thanks anyway Matt :)
