    more bass!

    is there anyway of running a separate sub in the A4 Avants with symphany head unit? as I assume it doesnt have co-ax outs on the back? as I want a little more bass than the normal set up can give (dont get me wrong the OE set up is veerryyyyyy goood!! but I do like my big bass)

    cheers

    i added an Infinity Basslink enclosed sub and amp unit to my TT coupe with bose a good few years ago, that had the symphony head unit.

    I think, but its only think.... there should be a set of rca outputs on the rear of the headunit (cant remember - it was around 2004). Would deffo recommend the unit, its got a 10inch sub inside, is nice and compact and has plenty of whoomp to it. Think it cost about 130 all in as well and I fitted it in a couple of hours.

    The Symphony II doesn't have RCAs (nor does the Symphony II+), but it does have line level outputs. WThe rear line level signals are always used so adding a sub in parallel would mess up the impedance and levels, so you should add a line doubler to generate a separate line level signal for the sub amp - and control the sub amp from the same amp enable signal as the OE amp.

    Karl,

    Now dave has mentioned it I think I may have soldered in some RCA's off the high level outputs. That Infinity Basslink has high level inputs too, I know I've mention the thing twice now but for the money it was spot on and it wasn't too obtrusive in the small boot of my TT.......wish I could have been bothered to take the thing out when i sold the car.......
