Taco audio makeover

I will officially introduce myself to the tacomaworld...
I have a 06 DBL CAB and I have replaced my HU with a Pioneer DEH-7900BT.
I installed Infinity Kappas 60.7s in the front; Sony 2-ways in the rear,a single sub box from supercrewsound.com with a Infinity 10" sub... I picked up a Profile 2-channel amp to power the sub (I am very happy with it, so far).
now, onto the question:
I wanted to power my front components... they are hungry for some juice. The Kappas want 90 RMS @ 2 Ohms.
I got another profile amp which will put out 100 RMS @ 2 Ohms.

my problem is running the speaker wires from the cab into the doors.
Can anyone please let me in on the best way to do this????
I've searched around online and some have just spliced into the factory wiring to avoid the hassle of getting new wire to the doors and then ran good 14 G wire to the amp.
I have tried to push the 14G wire through the rubber sleeve with no luck... Toyota has it jam packed with all the other wiring!!
is that a good idea or will I be sacrificing quality by using the factory wiring, even if it just for a short jog???

I really appreciate any input. I've been working hard on this stereo upgrade, and I hate that I have hit a 'wall'.

thanks for your ideas. Forums like this are an excellent tool for all of us!

 

an old installer trick is to remove the boot from the door and the body of the car so that it is loose on the factory wiring. you can then take a grabber tool or something straight (an old wire coat hanger for example) to push through the boot. attatch speaker wire to the end and pull it through. wire lube will help as well.

 

^ thats exactly right thats the way i have done it on my last three cars only othee way is to t-tape into you wiring harness from your head head unit but you will need a wiring diagram to do that, not sure of the quality when using this method just another way i was tought to do it .

 

thanks for your thoughts;
I'm honestly scared to remove the boot... I don't want to mess anything up permanently...
I think I will try to tie into the existing wiring....

here's another question to those with component speakers:
where did you mount your crossover? I have mine mounted on the inside of the door sitting on that foam block?
I noticed some have installed theirs back with amps (i.e. taco tunes) that's a lot of wire to run!
