Replacing speakers, headunit, and adding a sub questions

[90_Red_LX]

Title pretty much says it all, I'm probably going to pick up my cousins 12" solo baric for a decent price, and I'm going to put all new pioneer door speakers and pioneer speakers for the back in. I'm also probably going to run either of the following two head units:

Me and my dad will be doing the installation ourself. I've heard that I'm going to have to run a new wiring harness or hack up the one I got. I'll just run a new harness, even if it is more troublesome. I assume my lx has 6 speakers since it has what appears to be openings near the top of the dash for speakers. It doesn't have the equalizer though, if that makes a difference.

For the sub it's going to be a 12" solobaric, probably in a truck box. I'll probably put it up against my back seat in the hatch. I don't want to drill holes in my car so I'll probably lay a sheet of plywood down in the back and bolt the box to it unless you guys have a better idea which would be cool.

For the amp, for the time being I got a decent one from my friend who upgraded his after christmas so I'll probably use it for the time being. As for the possibility of running an amp for the door/backseat speakers, would it be worth it money and time wise? Or would it sound just as good running from the head unit.

Thanks!

you have a couple of choices here,but i'll start with the wireing.If your going to run a amp to all 4 speakers(so your fronts dont get drowned out),the your gonna need to run new speaker wires anyway.The only power you can get from the stock harness is the power(constant and switched) and ground to power the stereo. Everything else is useless.I would suggest running 2 amps one 4 ch. for the F/R speakers and then one for the bass,if thats not in your budget,then use a good 4 ch. and run the F/R at 2 ohms(only problem is you cant fade) and then use the amps rear channel for the woofer.I wouldnt use a truck box,it probably doesnt have the right airspace for the woofer.Run a 8 GA from the battery to the amp, with a inline fuse near the battery.

I got a decent 4 channel JVC amp that my friend gave me that I may use for the f/r speakers since it's not a lot of wattage. I'm sure it would be a plenty for them speakers, then pick up an alright amp for the sub. I thought about picking up another box , but I still have to figure out how to mount it.

personaly if highly suggest not hacking up the harness but using an adapter. all you need is the power for the radio and the remote for the amps. that way if you want to change it back to factory or just a radio by itself then you can. As said above the amps will work good. id ditch all the factory speakers and use a component setup up front and some 2 way 5x7's in the rear.

I'd definetly not hacking up the wiring. I just don't do that, and I'll probably return it to stock one day. I'll probably just either run power from the radio or this amp, my friend wants the amp so I may just sell it to him and run power from the radio, then an amp to a 12 in the back. I really don't run all new wiring either, and I'm just looking for a decent sounding system, nothing to really impress anyone with.
