I've got Kappa's up front on mine and a CDA-9833 HU with the V-Drive built-in amp and they're awesome. Much better sound than the Reference series I have in back. (Should have spent the extra $30 for the Kappa's to go back there too.) Unlike incubusjunkie stated on the bass many songs I've played have excellent bass. Actually had to turn off the Media Expander too lower it so it wasn't so distorted. With mounting them I was able to use two of the original mounting holes and just drilled two new ones. Use some good double sided tape for the in-line X-overs other wise in the extreme heat like here in SE N. Carolina they will come off the inside of the door any clank around in the door.
