Here's what you need..

-Either a head unit with Pre-amp outputs, or in your case,

-An amp with high-level inputs or

-a high-level to pre-amp convertor.



Figure out which wire is + and - in the factory wiring. Tap the rear speaker wires with Scotch-locks (T-taps, whatever you call 'em) and paired wire (I use two different colors of paired speaker wire). Paired wire has one marked (black stripe) and one unmarked wire. Usually, the marked wire is ground. Do this for the left and the right. Route these wires either to the high level input on the amp or to the pre-amp convertor. If you're using a preamp convertor, you can usually route the feed wires from one side of the car to the other, then hide the preamp convertor under the body panels of the other side. Then you can run the preamp (RCA-Style) cables to the amp.



As for the remote-signal wire (usually blue in an amp install kit, tells the amp when to turn on), your choices are-

-Find a convertor that senses voltage on the speaker wires and signals a remote turn on

-Tap into a +12V SWITCHED source.

You need a switched source for this blue wire because if you hook it straight to the battery, and also hook the main power wire straight to the battery, your amp will remain on all the time, even when the car is off. Using one of the above methods will provide you with (at minimum) an amp that will switch on and off with the car.



Any more questions, post 'em up!

 

ok well im kinda confused but from what i got i need to tap in to the wires from the rear speekers hook my amp to thoes then the remote wire i need to find a 12v source to hook it up too with a switch... did i get you right or am i way off? and where is a 12v source in the car??

 

It'll be real easy if you tell me what brand and model amp you have! i can draw a diagram.

 

draw the diagram with paint

 

Oh, I will.. believe you me

 

its some off brand amp. i dont even see a name on it. but its all on one side ifrom left to right it goes...ground.power.remote. - + + - . then 2 more ports.

 

so there's no speaker level inputs. You're going to need a convertor that will tap the rear speaker wires and leech the signal and convert it to line-level (RCA style cables).

 

Just buy a cheap-o head unit with RCA leads from a hock shop.
