I know what you mean about not wanting to break anything in the process. I did mine with as little modification as possible incase I sell my car some day. I used the cables in the back coming from the HU to the amp and wired them to an LOC to get RCA's. I then wired my crossovers and amps. I used the existing speaker wires going from the amp out to the drivers to connect my after market speakers. It's not ideal, but if you want to keep everything like it is and get louder sound you can use T-taps. You don't have to cut off the connectors for the amp and speakers. You can tap into the wires to get your RCA's and run the signal back to the speakers. I used t-taps at first but then cut the wire and soldered it together. That way if you want to hook everything back up like it was you can. I wouldn't recommend running different ohm speakers off of the same crossover or amp. Doing so can ruine your speakers or amp unless you'r going with an active setup.
