Hello all,

First time posting in here but a camper appears to have arrived in our driveway.

Although it is brand new and very nice inside I would like to upgrade the speakers and, most importantly, the sound deadening.

We are based in Hertfordshire and I have been looking round for a company to take this on without much success so far.

Whilst I am reasonably competent with these things I do not have any time before we plan to use it in April.

From any of you that have done this before is there a company you might recommend? If not do you think I should be heading for car audio specialists or camper specialists?

Many thanks

I suspect any decent car audio place will be familiar with fitting sound deadening panels etc.

Alpine do motorhome specific headunits if you are feeling flush.

If your van has the popular Remis front blind system it should have space for tweeters to be added to the A-pillars.

I can highly recommend Audiofile at Bishops Stortford. He did an X5 for me a good few years ago now but he’s one of the best in the business.

Lead times might be an issue though.

Personally, if it's brand new I'd be making sure it worked properly before I started fking about with it.

Give it some proper use to get the bugs out before pulling apart an expensive toy. Right now you have no idea if it's any good, and if there are problems with the interior fitout whether it came that way or whatever audio installer plays with it fked it.

It's not like it's unknown for a camper to be a mess that has to be returned to the supplier.

Another one who says get it all working properly first, so that warranty support is not compromised.

When you say sound deadening, do you mean cab while driving or the accomodation?

They look decent, thanks for the pointer. I will give them a call in the morning. Hopefully my timescales will work within theirs.

Thank you (and Josh) for that pointer. It has been stayed in and driven over from Germany already by my brothers in laws who have a similar camper and all seems really good so far so it has had a little bit of a test run.

The main thing is wind noise on the road, dialling that down a bit would be a real bonus with the added benefit of better night times.

Problem is if it's what it looks like - a fibreglass roof - then the wind noise is going to be coming from the shape and the joints and short of maybe checking the detailing and the seams there's limits to what you can do.

It isn't going to take deadening like a steel panel would and I'm also not sure there's going to be huge scope for stripping the interior and fitting useful things behind it.

There's all sorts of things that could maybe be done, I'm just not sure how well it would be possible.

On a practical level the hard part is removing & refitting the interior, not fitting a sound management product, so I'd suggest that's better suited to someone who understands the vans. Or maybe it's a split job, one to strip/reassemble and one to do the fitting.

Our Transporter T5.1 was a more basic spec. I whipped off the door panels and floor mat and chucked in some (not total coverage) sound matting. It made quite a difference.
I've also installed wind deflectors, which as well as being chav spec did quieten wind noise a tad.. More importantly you can sleep with the front windows cracked open even in rain.
I also have a glass roof, but mine is slopes not overhanging. Over 60 you can hear the wind noise increase and watch economy plummet. So I sit back and chill at 60...

Those Citroen/Pug vans are blooming noisy for wind in my experience. The last one I hired was really loud, and I did wonder if the really hard plastics of the dash was 'echoing' sounds around. Worth popping some fabric / fleece jacket on the dash and taking a test drive to see if that helped?

i'd be looking at add closed cell foam to the fibreglass parts where you can, get the benefit of deadening without huge weight

The sound deadening title got me interested. But now I am somewhat disappointed.

Our 44 year old campervan, when driven at 50mph leaves me and the wife with sore throats after two hours. We have to shout at each other to chat over the road noise!! smilesmile

Tried sound deadening, better stereo and speakers and it has probably dropped by 1db.

Better option might be to see if there's an active noise control system you can find & have installed?

Automotive ones have existed for 25+ years so I'd hope there was something available.

There's your problem right there.

I doubt that it is possible to reduce that noise.

Depending on how far you want to drive, Car Audio & Security have been around forever, never used them myself but I understand they have a good reputation.

Be interesting to see how you get on with the sound deadening, I've been meaning to get the doors done on our MoHo for a while now. Had great results with Dynamat in my MK2 Golf GTI 20 plus years ago.

Just to update this thread.

The van went off to Audiofile in Bishops Stortford, thank you to those that recommended them.

We added sound deadening to the whole of the front cab floor, dashboard and doors.

We also put new Audison speakers in the doors, upper dash and in the rear.

Sound quality and staging has improved massively. The van is also a lot quieter between 20 and 62mph. Above 62mph the lack of aerodynamics takes over again!

At a steady cruise of 62mph on decent tarmac it now registers 67db.

Audio file did a great job, were far from cheap but certainly provided a good service.

Thanks for the update. Are the speakers powered by an amp or just the head unit? Which brand of sound deadening did you use?

With our MoHo we rarely take it over 60 as it's just noisey and uses even more fuel, so this could be ideal.

It was mainly Skinz car sound deadening. I’ll add some pictures below to get an idea of the work done.

The speakers are all being run off the standard head unit which is plenty for this. I did consider adding a Sub but it would probably have been overkill and we are also very aware of being close to the weight limit for the ‘van already.

Glad to hear Gary sorted you out and that are you pleased with their work.

Certainly not cheap but workmanship is on a par.

Keep enjoying the van! smile

Thanks for that, I'd have thought they'd put it on the inside of the door, not the door card. Which is why you use professionals, haha.
