I'll be at StCan I be cheeky and briefly hijack your thread to get some advice from Paul?

This topic has made me nervous.

Me?

Ok.

I would have to say I would worry about only a 4" to deliver a full front stage
![](./images/smilies/spacer.gif)
(Even though it's a Focal), that said the Mk1 is dash mount?
![](./images/smilies/spacer.gif)
I would be tempted to get some simple door builds and fit a 6.5" there rather than the sub.

You can still use the Xover in the Genesis Profile 4? crossing
![](./images/smilies/spacer.gif)
<150Hz or so.

One thing you need to understand about the MR2.

The cabin is small, and this has an effect on the phenomenon known as
![](./images/smilies/spacer.gif)
'Cabin Gain'.
![](./images/smilies/spacer.gif)
Basically you get a bass boost of 6dB/Oct
![](./images/smilies/spacer.gif)
(or is it 12?) below a certain frequency due to cabin volume.
![](./images/smilies/spacer.gif)
Personally I get a little more bass extension with the Tbar out or the windows open a crack.

A dedicated sub is only good if you like the
![](./images/smilies/spacer.gif)
'pressure' or a distinct kick in the kidneys.
![](./images/smilies/spacer.gif)
For the 165's, you could consider a JL 6w0 or other respected make
![](./images/smilies/spacer.gif)
- I don't think a great deal of the focal 5ws in a car
![](./images/smilies/spacer.gif)
(I have a pair I tried, they will probably end up attached to the PC
![](./images/smilies/spacer.gif)
)
Considering the additional cost, you may consider going to a full 3-way Polyglass 165 V3E Slim
![](./images/smilies/spacer.gif)
- it would certainly be my
![](./images/smilies/spacer.gif)
'starting point' and only go to the sub if I wasn't satisfied and was happy with the added bulk.

Being in Reading, I assume your dealer is John Kleis? they are a Focal
![](./images/smilies/spacer.gif)
/ Gensis dealer, and have been in the game a LONG time.
![](./images/smilies/spacer.gif)
They may be open to demo-ing a set
![](./images/smilies/spacer.gif)
'in car'
![](./images/smilies/spacer.gif)
- the typical wall demo-stand setup is not the best for comparison, as the baffle size will extend driver bass response artificially.
![](./images/smilies/spacer.gif)
Whatever you do, spend a little money on Dynamat or similar
![](./images/smilies/spacer.gif)
(Does
![](./images/smilies/spacer.gif)
Brown Bread or
![](./images/smilies/spacer.gif)
Aura Dead Sheet still exist?) for the back of the surrounding dash plastic as I suspect it will make a huge difference.

I used to compete in IASCA UK Competitions 93/94 with a Peugeot 309 using
![](./images/smilies/spacer.gif)
(in its last guise) a home designed pair of compression driver
![](./images/smilies/spacer.gif)
Waveguides using the windscreen for horrn extension
![Wink ;)](./images/smilies/icon_wink.gif)
with a pair of Focal 8K011dbs and passive 24dB Xovers and a pair of infinite baffle Infinity Reference 12s

(the original carbon ones)

The MR2, since I first bought it in 2000 has had:
![](./images/smilies/spacer.gif)
Kef Uni-Q KAR160Q
![](./images/smilies/spacer.gif)
+ Focal 8k5412
![](./images/smilies/spacer.gif)
(I think)
![](./images/smilies/spacer.gif)
on a Soundstream Ref 405
![](./images/smilies/spacer.gif)
+ Alesis MEQ230 with balanced line conversion
![](./images/smilies/spacer.gif)
Kef Uni-Q KAR160Q
![](./images/smilies/spacer.gif)
+ Focal 8k5412
![](./images/smilies/spacer.gif)
(I think)
![](./images/smilies/spacer.gif)
on a Soundstream Ref 405
![](./images/smilies/spacer.gif)
+ Behringer DSP8024
![](./images/smilies/spacer.gif)
(31ch EQ and RTA) boot mounted.
![](./images/smilies/spacer.gif)
Focal 165K3
![](./images/smilies/spacer.gif)
+ Focal 8k5412
![](./images/smilies/spacer.gif)
(I think)
![](./images/smilies/spacer.gif)
on the same setup
![](./images/smilies/spacer.gif)
Focal 165K3 with a Phoenix Gold M50 under the passenger seat
![](./images/smilies/spacer.gif)
Focal 165K3 fully active with Focal 5WS behind seats using a Rockford Fosgate EPX-II Xover and EQ, and two Soundstream Ref405s modified by me

Focal 165K3 Passive with Focal 5WS Xover by the headunit, M50 for the 5ws Phoenix gold ZPA0.5 for the 165K3s

You are welcome to have a listen of the car anytime
I expect to be over Reading way in the next few weeks when Bracknell T&B get my tyres in

PS, Cable
In a car, any special
![](./images/smilies/spacer.gif)
properties of speaker cable will be lost as soon as you
![](./images/smilies/spacer.gif)
stick it next to a steel chassis!
![](./images/smilies/spacer.gif)
Any good phono cable should do in car
![](./images/smilies/spacer.gif)
DONT be tempted to spend a fortune, experiment at a later date
![](./images/smilies/spacer.gif)
(get something OK from Richer Sounds)
![](./images/smilies/spacer.gif)
Speaker cable, QED 79-Strand is good enough
![](./images/smilies/spacer.gif)
just look for THICK as you are dealing with 4Ohm speakers remember.
