If you know a manufacturer who would talk.. I'll work with them!

Speakers: I'm thinking of using the JL Audio convertible 2-Way 5.25" and just leaving my factory tweeters in the grill unplugged while using the JL tweeters on the mid driver if there is no fitment issues with the stock grill.
I don't need a sub and just looking for louder mids and highs so that I can hear my system on the highway. I had this same amp with Hertz speakers on my Harley Street Glide and it was extremely loud and crystal clear. Rockford made a simple plug and play wire harness for Harley Davidson but I can tell the F6B is going to take a little more creativity and work.
appreciate any input or guidance if what I'm thinking will work.
Hey AnthonyGen, welcome to my thread! If I understand correctly, you want to use the existing speaker output from the OEM amp for an input into your Rockford Fosgate? Yes, you can, but you may not get the results you expect. I found the line-level output is out-of-spec (impedance is non-standard and/or the output voltage is below spec) which is why I recommend using a decent line driver or a DSP that can handle it.
The OEM tweeter has a cap to filter lower frequencies, so as long as you tap prior, it would work as inputs for your amp. I would highly recommend that you test this setup before doing a full install. Several folks have tried this common approach, but it resulted in a distorted output from the amp to new speakers. Others have tried using an inexpensive speaker level to line level, but it didn't result in much improvement for them. I was successful using a line-driver to get a better result, but I opted to go with the high-end ($$) solution of an amp with DSP instead. The Rockford's high-level input MAY work for you, but results may vary so test it first and if it doesn't sound like you would expect, try adding a line-driver to see if that improves your results, especially one that has a bass boost to make up for frequencies below 100Hz that are cut by the head unit.
The F6B's speaker gauge can't handle the output of an after-market amp, so make sure you run your own. Ideally 12 gauge, but 14 may work for short runs.
If anyone knows a manufacturer who will return a phone call, let me know. I'd love to get a harness designed for us! I hope this helps, and best of luck.
Cheers!
