    Upgrading my sound system. Keeping my HU. Keeping Factory amp. Removed factory subwoofer. Installed new tweeters and door speakers so far.
    Behind the rear seat is my factory amp. From there I tapped the remote wire for the new amp. Now for a signal feed I decided to use the front left and right speaker wires coming out of the factory amp running to the speaker level inputs. Anyone have any better recommendations? Should I use a loc or is speaker level inputs just as good?
    Also, I looked everywhere for a wiring diagram for the harnesses at the factory amp? Had to do some guess work on finding the remote wire and pos/negs.

    With the JBL system there are a few options, because the amp has internal crossovers. This means the tweeters only get highs, the doors only get mids, and the sub only gets bass.
    So if you’re wanting to add in new speakers that get full range, you either need a device like the PAC AmpPro that creates true full-signal preouts, or a device like the AudioControl LC7i that can do signal summing (combine the lows/mids/highs all into one channel)

    the AmpPro is the best solution, hands down.
    The LC7i is a god alternative but requires more work and wiring.

    as for a diagram, PM me your email

    Is there any I can tap in before the amp with an LC7i(which is what I have) or. Eventually, I would like to get rid of the JBL amp but I'm taking baby steps. first step is adding an amp for the door speakers that I just installed.

    No tapping in before the amp, without adding an AmpPro or similar
