    What would be the easiest way to wire up a 4CH amp to the interior speakers?

    cut the wires from the current setup and run them to your amp

    This method is kind of confusing but it works. It uses the factory speaker lines in a looping action. I've seen this done for years with no problems and it changed the way i do my installs. The rear speakers are directly connected to the rear speaker lines, where the front speakers use the factory lines where the lines go back to the radio wiring and then goes through the rear speaker lines. Heres a short walkthrough:

    1. With the factory speaker lines behind the radio (easiest with a harness), connect the right rear lines to the right front lines
    1b. do the same with the left front to front rear factory speaker lines.
    2. Run both Front and Rear speaker lines directly to your rear speakers.
    3. Then connect the rear lines to the speakers
    4. connect the front lines to the factory lines that should have connected to the rear speakers

    I cant stand it when people go "how do i get the wires thru the door?"

    if you have wires from the front speakers behind your HU why would you even think you needed to get the wires directly from the door...?

    I know this guy didnt ask that, but some do and you would think people would want to do the easiest thing.

    How about because the stock wiring is usually 20-22 gauge. Pathetic.

    The easiest way is rarely the best. Especially when the OEM HU that used those speaker wires put out 5w x 4 RMS, and I'm now sending 100w x 4 RMS. If you bought an inexpensive low-powered amp I can understand, but what I don't understand is why people spend hundreds on ridiculously oversized 0/1 gauge power wire to replace alternater to battery connections and run to their amps, hundreds more on expensive component speakers, and then wire to the tiny stock speaker wire at the HU, which gets routed all over the car alongside other power-carrying wires in the factory harness before making its way to the doors and rear speakers.

    I like to use at least 16 gauge to speakers. And grabbing the stock speaker wire at the door makes a LOT more sense than the dash. If you only use the section from just before the door you'll be minimizing power loss since it's such a short section wire, and you don't have the added work of getting wire into the doors.

    The way I usually do it when wiring up friend's cars is to go straight to the rear speakers, which are easy to get to, but use the stock front speaker wiring just before the doors. It's worth spending an extra few minutes to do it right if you're spending thousands on a new setup.
