I found that the A4 is alot easyer to upgrade to an after market system because the stock speaker wires all run to the trunk and they seem pretty beefy so I just labeled every thing well I took it out and went from there&gt; Though I did run 4 gauge power lead to the trunk I Temporarily mounted my speaker amp under the rear deck(upside down) but it turned out to be permanent after prolonged procrastination.</P>


my sub amp was mounted to my box driveing s series alpine subs but after much noise and smoke all was a loss except for the box (its reazlly amazeing how much smoke 2 12s and a 500 watt amp can produce<IMG src=smileys/smiley11.gif border="0"></P>
