The easiest way to set up your tens is to first off remove the existing head unit (The Radio) And replacing it with one that has RCA cable connections (RCA OUT is all you need, they are about 70 - 100 bucks). In order to use the existing inside speakers you will have to power up the stock amp and still run through it. Color codes wont match you have to get a wiring diagram, I lost the link to the one I used someone here will link it for you im sure. Then you have to run a power wire to the trunk to a new amp. Are they high wattage 10's or competition speakers? A 2 channel amp will do the trick. Select wattage accordingly.
Your supposed to run a remote wire from your new CD player to your amp. I bypass this and add an in - line switch to turn the amp off. Just connect the red to yellow on head unit, and use jumper wire for remote to the trunk, on the amp itself.
My system quakes pushing power out my head unit to and through the factory amp and then to the stock speakers. I found only hooking the left and right speakers output from the head unit, to two particular wires behind the dash will ignite all the speakers in the car. Approx. setup time is 2 to 3 hours if done right.
On a gen 1 running the power wire is easy, theres a rubber plug behind the glove box the goes through the firewall, very easy. Then run em through, tuck it up , wires go right under the back seat and there is a path to the trunk, about enough for 4 wires.
Gen ll Is another story, short of drilling a hole in a place where its safe and accessible is still a mystery to me, I got mine through the hood to door hinge, drilled sideways to where the pedals are, still a pain. I suggest having a gen 2 professionally done.
Thats what I have found working on mark 8 sound systems. Hope this helps !
Well, I'm glad I asked before going ahead and trying to hook them up! What's involved in the process of replacing the factory amp?
