[QUOTE="ado, post: 5404192, member: 603881"] I got an Alpine SPX-17PRO kit. I have some questions on it. I know it is bi-ampable, but I'm only running 1. On the input there is WF+/- and TW +/-, My question is when the jumpers for the signal link are in place, which terminals get the amplifier power? On the phase link module it looks like I'll need number 6 since the woofer and tweeter will be around 5" apart. I had a question on what the specs on these meant. What does it mean when it says TW on or off, SW on, on the acutal module. I noticed #3 is the same distance but SW is off and TW is on or off. One last thing. I am running them with an alpine 9887 set to 4.2ch (F/R/Sub) Mode. What should the frequencies and slopes be set to as a starting point? I know it varies with vehicles and installs, I just don't want anything to get ruined before I even get a chance to use it. Thanks for your help. [/QUOTE]
