Title: That wasn't supposed to happen - USW10
Post by: Justin.D on July 23, 2018, 15:58
As some others have done I had an In Phase USW10 mounted under the steering wheel. All nice and snug, metal brackets, spring washers or nyloc nuts. All was great until the bloody metal brackets sheared and it dropped onto my feet while slowing for a junction

Thankfully I managed to limp to a close by car park to remove said weight from my feet without incident

Anyone else with something heavy under the steering wheel please check everything is as it should be under there

Agreed - all while finding a new "safer" place for said heavy item

Those "brackets" look like corner braces for lightweight timber work, my guess is they've been continually flexing from the bounce of the unit and rearranged the structure of the alloy until it gave up. I'd suggest a third one at a right angle to the others to stop the bounce and you'll be right.
And some mild steel/stainless brackets. And a retaining strap. And a cargo net underneath.

Yep, that's exactly what they are - the other bits are still attached to the car. I'm also looking into a custom welded angle iron bracket

The cargo net is a blinding idea, lol

Good shout, ideally you just need the brackets at right angles to each other to stop the speaker swinging on them and flexing the brackets. You'd probably have got away with it even with the light alloy ones.

Builders band can be wrapoed round and attached to a variety of places to spread the load.

I don't think I'll trust the light alloy ones again, even with additional support.

I'll come up with something, even if I do lose some space in the bins behind the seat

I'm even considering a rectangular sub instead of this one - one that's flatter to go behind a seat without losing legroom

I did consider the banding - I'm worried it'll vibrate and 'ting' though

+1 on the builders band, got yards of it on mine!

I finished mine off with a rubber covered luggage tie which stopped the vibration I was getting.

Any of you guys going to ShinDing? Perhaps I can have a look at your solutions and go from there

Lol. I'm scheduled to be attending and you're welcome to have a go at seeing how mine is mounted but you're going to have to be upside down in the driver's seat![emoji23]

Nice one - I'll bring the torch too. I spent enough time upside down under the steering wheel when I initially fitted mine - It'll be ok. Thanks CTM

I may well be at shin dingday too.

There are a couple of pictures of my set up (before the rubber tie though) on the 1st page of my readers ride although I have the kenwood sub not the inphase one.

These ones aren't going to break!!! I meant to fit this yesterday at ShinDing but got carried away chatting and generally having a good time

Are you a couple of coat hooks short in the hall now?

Any star washers on those? I mean they shouldn't vibrate out upwards but...

Coat hooks. I could have used coat hooks.

I have a mate who is floor manager in an engineering shop (They make Car Transporters mainly). These are a cross section of 5mm box section

Spring washers - will these do instead?
