Hi all, I got a Kenwood Woox compact powered sub. I'm going to install it underneath my passenger seat. The wiring for the sub is in a harness(much like on an aftermarket headunit). Everything seems to be in order except I can't figure out how in the world to connect the power cable to the battery. Here's a picture of the connector on the end that's supposed to connect to the battery from two different angles.I know it's the proper end because that's where the inline fuse is. removed picture now that i have it installed I've never seen a connector like this and the manual doesn't really indicate anything, it also doesn't show any piece that I'm missing so I have no idea what to do. Can I crimp a regular O connector on it(that I run the bolt on the battery connector through)?Any ideas? Second, if I'm going to use preamp inputs on the sub. I am gonna install the sub on the passenger side but I need some advice on how to actually run the cabling. I understand how to release the door trim in order to get underneath the carpet, but as for running the power cable to the battery, how do I get it through the firewall? I've heard there are some premade holes, but how do I actually run the wire through there, attach it to a bent coat hanger to snake it through or is there a better way? Thanks for any info, this will be my first time installing an amp and or powered subwoofer so I'm bit nervous but I'm confident I can do it. Thanks Edit-I think all I need to do is get a skip on ring connector that will fit on top of the tip of the power wire. Is that it or do I need something else?
