[QUOTE="genxx, post: 3130723, member: 575023"] No defeat the amp x-overs if using the HU. If they cannot be defeated example Eclipse XA amps IIRC, just set flat. Second answer no It does work that way. If you use passives make sure that what ever is feeding them set the x-over's to full range. If not you will cut the freq's that you may need for that driver. Example:You x-over one set of channels for your mid-bass/bandpass. Now you have your x-over set on that channel to only play down to 80hz and only play as high as 3khz. Then you sent it to your passive network the passive is only going to recieve 80hz-3khz. But the passasive is running tweeters that should x-over at 3.15khz and up. You can mix match that any way you like and you are not going to get the results you desire unless you let the other drive roll of naturally on the top end. Then your passive will work in that scenaro. I hope that made since. I may have just made matters worse. Not the greatest at explianing this. If you are trying to go active then do some research it is not as easy as people think. The term active gets thrown around alot. If you are attempting passive you need to understand how it all works, x-over points, slopes ect. [/QUOTE]
