just installed my new Alpine 2-way comp. system, had the dash out and built the new tweeters into the dash so you can angle them. Also had to cut out in the doors because the woofers were a bit longer. Looks so sweet and the sound is amaising. Now I only need the money for a HU. that can macht the speakers(I also have som Alpine in the back) looking at the Alpine CDA 9815, any adwise what to get?
