[QUOTE="DUAL10S, post: 7686433, member: 564550"] No problem. First thing - Alpine anything is gonna be better than the Pyle amp you mentioned earlier. Second - the 8g wire is for the Power and Ground wires - speaker wires should be fine @ 16g. 8g should be the min for the amps in this power range and this will have to be run from the batt (+) to the amp (+) power input. Dont forget to install a inline fuse around a foot from the battery. If you have decided on a 4ch amp more than likley you are gonna be running @ 4 ohm x 4 channels. Based on the listening volume you described I really dont see a problem with the elec system. Keep in mind some of those rms rating are @ 14 volts. If ya are @ 12v gonna be a little less rms power. Even if ya do go with 2 ohm speakers the elec should be ok at the volume level you are talking about. Agree it sounds like it wil be easier to splice into the factory wiring. But just so we are clear, there cant be any kind or signal coming from the factory radio to the speakers. This is the main reason i suggest to run new wire. Dont want to risk hooking a power wire to the amp outputs. Also, does your MP3 have FM? Because the only signal going to the speakers has to come from the amp. The only signal to the amp will come from whatever you plug the mini jack into (ipad, phone, mp3, laptop etc.....) I know it may seem like a pain to run new wire but you will have peace of mind knowing the connections are correct and will probably eliminate any kind of engine noise. On that note dont skimp on the ground connection - keep it short and get all the paint off before installing the ground wire. And dont skimp on the RCA cabels as well - get some good quality cables. If ya ever decide to pull the system (sell the car) a quick reconnect and ya got a working factory stereo (will help if ya trade it in later on) ya never know. And you still got all your gear for the next vehicle. Wish I would have done mine this way. Those three wires (power, ground and remote) that make the EQ work are the same ones that will make the amp work.
