Installed the Stage 1 kit. Took about 1.5 hours total.. Easy fit.. I opted for the easy route this time because I don't have time to monkey around with finding speakers and making them fit..
Sounds really good, but I don't have a good direct comparison.. I tried to listen before and after, but got pulled away when I was just finishing up, and now can't say how much better it is!
I ended up finding a sub box from a friend, so the Basslink 2 is for sale if anyone is interested.. New in box, took it out and looked at it, then put it back in!
Paid $250 + HST, selling for $225 obo
I will post when I get the sub and amp installed!
