Good job! I love Alfa 147's!

I think I might have done the sound damping a little different and put the exvibration pro on first and then the sheets. Never seen it done like that.

did you make those distribution blocks yourself?

the whole install is awesome!

Excellent install! I'd be a little nervous about that distribution block being unprotected though. Don't want anything shorting out.

Very nice work. Did I miss the sub??

Thanks all.

All this work it' handmade by myself (and in same point isn't good :oops: )

@Misfire: Hum, at the moment thw sub it's in this position

Image (sometimes I need to remove it)

@Bfowler: Yes the distribution block it's made with the help of my friend that have an CNC machine.

@joerg & ttocs: The structure it's

1 layer of Butyflex T250/AL link to the datasheet (sorry only on ITA)
2 -3 layer Brax eXvibration Pro

4 layer (only on external folder) Isolmant similar at the Vinyl product.
