Anyone fitted a sub to the bravo 2007 range with the standard headunit that has blue and me?

i want to keep the standard head unit and try fit a sub to the car as i feel that will improve the sound quality a little bit.. upgraded the rear speakers and considering doing the front next.

Dont think the Standard HU has a pre out on it though does it?

so is there anyway of like taking a link from the front speakers or rears? and just taking the trebble frequency out?

Yes its possible I done it with mine. You can get the feed from any of the 4 speakers and attach a Line Out Converter (LOC). I bought a cheapo 1 from Halfords and it done the trick. Was no where near as good sound as a pre out but much cheaper then changing the whole head unit etc...
