    Alright, I guess the distribution block and wire issue are clear now

    for connecting the 4 channel amp to speakers, do i just tap RCAs from HU to the amp and then connect the speaker wires from all the speakers to the amp?

    you can tap the rca's on the HU if it has front and rear pre-amp outs. If not you'll need to look into a box to step down the speaker outputs of the HU into preamp signals for your amp. I really can't suggest using the high level input on any amp, as they always seem be horrible.

    ::EDIT:: btw, what monoblock amp do you have, i'm trying to see how much capacity you have left on that 4awg line for your inverter

    Well the mono amp uses 2x 20amp fuses, and the 4 chan is using 2x15amp fuses....

    Leaves ~30amps for the inverter if you want to max the line out, as 4awg has about a 100amp transmission carry ~25ft (about the length from hood to trunk).

    The inverter shouldn't be any larger than that considering its just for a laptop

    ALRIGHT!!! Thanks!
    my stock HU has preamp out, i just need to tap the wires to RCA. Do you think i need to solder every wire with RCA or just like twist them together?

    is it that I will be able find all the speaker wires when i take out the door panel?

    solder would be preferrable, best connection. Are you sure ther are pre-amp outs? If they are the wires that connect directly to the speakers, those need to be converted down into RCA's, as they are to powerful.

    What do you mean by the second question, as i don't quite understand.

    ah, seems your HU does have wires to tap for pre-amp outs. Sorry, i was assuming it didn't, as usually you don't get lucky enough to run into a situation like this. Follow that guide for your front and rear RCA's then like you had planned.
