bought some tt pedals from audi took 5 mins to fit look great. My stereo system was kaput so i bought some Alpine SPG-13CS components for the front and some FOCAL 165 CA1 for the rears. while i was doing all that decided to buy a ALPINE IDA-X305. still yet to recieve. ran in new speaker wires for all speakers and used andymacs front adapter and made my own for the rears. they sound really good just powered off the 20w piterful amp in the original HU. cannot wait to instal the alpine unit . also while i was at it installed a lcr splitter took around 25 mins looks great cannot fall off. i used this guide. http://public.fotki.com/BlueTTop/mods/lcr-splitter/ overall happy with my little mods. next on the line up are some kw struts and springs and stage 2. bring it onnn ha.
