Clio Headunit

Firstly, Hi to everyone! This is my first post here

Picked up my Clio DCi 100 last Thursday and am very happy - the fuel economy is great, 55mpg! Compared to the 20mpg from my last car (Petrol Turbo tho not a Diesel) I'm well chuffed.

Anyhoo, have just changed out the factory headunit for a Sony HU and for some reason the steering wheel remote won't work! I have the adaptors from Halfords and everything is plugged in and connected up correctly (as far as I can tell - you can pretty much only plug things in one way!) but the remote does nothing

I'm sure it isn't a problem with the HU as I used an adaptor in a previous car for the steering wheel remote (a Vauxhall) and all worked perfectly.

Does anyone have any ideas?

Also, is it just me or are the speakers fitted as standard to a Clio Dynamique a bit cr*p? Anything past 3 notches on the new HU volume and hello distortion! Very dissappointing - my last Car's (a SEAT) speakers were really good for standard equipment - the only thing stopping you from turning it up was the fact that it was too loud! Has anyone fitted 6" speakers to the front doors of a Clio - I think the standard ones are 5".

Hello again,

Have given up on the steering wheel remote and bought a Sony one. The speaker problem is my main concern at the moment.

I've made a little progress. Standard speakers are 5.25 inch front and rear - I bought 1 set of new components for the front - quality is improved but distortion still occurs when the volume is increased. It is not a problem with the headunit as I have tested it out of the car at Halfords and distortion only occurs when you turn it up ridiculously loud.

1 theory is that the problem is with the power supply off the loom to the HU not being up to the job of running the unit - something which I am dubious to accept as more people with Clio's would be having problems and the fact that when tested the loom is supplying 12 volts. Being a second hand car I have no idea what the previous owner did to the car sound system wise - from looking at the loom I can see that the power and earth wires at some stage have been cut and rejoined - why I don't know.

It could be that the speaker size that will fit the car is quite small and it is therefore going to take much less to cause distortion, though the speakers I bought are rated to handle more power than the HU can supply. I have tried using larger components (6") and sound is good to the same point then the distortion occurs! I also ran a 6x9 speaker from the HU - sounded very good and didn't distort until a much higher volume level - bit impractical to fit in the doors though.

Someone, Please help!!!

The distortion is simply due to the fact that the speakers cannot handle the high levels BASS that you are feeding them..
As you have found the larger the speaker then the greater the ability to handle the BASS notes before distortion..

If your head unit has a Highpass filter control, then set it at a cut off of 80Hz. This will significantly reduce the distortion by stopping the frequecies below 80Hz... If you do not have this control then you need to insert a High pass filter in each speaker input to stop the BASS..

To get the BASS back you will need to fit an external subwoofer..

Hey thanks,

I was hoping that I could blame it on something other than the size of the speakers but oh well never mind. I guess when I tried the 6x9 and didn't have a problem I should have stopped kidding myself.

I have already set the high pass filter to 78hz on the HU though this is not ideal as a. it obviously removes all the low stuff and b. it filters the frequencies sent down the Sub preout as well meaning I have to set the boost on the sub amp to 6db or 12db

Best solution I am thinking is to bypass the wiring from the headunit and run the front and rear components directly from a 4 channel amp (using the front and rear preouts of the HU) that way I can set the highpass filters on the amp and just use the HU to adjust the EQ etc - avoiding the problem with the sub preout too.
