hi i need help to install an aftermarket stereo. i dont have an install kit. what wires are for the front door speakers? they run to a stock amplifier and then change color code to the speakers.

 

What year is your car? Are you by-passing the amp? A 9 volt battery with two wires attached to the terminals is the best speaker tester money can buy.

 

Taken from the FAQ



What are the wire colors for adding aftermarket radio
LTBlue/Red= 12v+
LtBlue/White= +Accessory
LtBlue/Yellow= -power ant trigger
Red/Black=+ Lumination
White=Factory Amp Turn on

Ground to the body, use the 10mm bolt behind the center console front drivers access panel. Do not use the Red/Black as ground it will damage the interior light circuit and dimmer in the car

Front Speakers (maximum of a 15 watt peak from the radio):
LtGreen/Red= Left
LtGreen/Black= Left

LtGreen= Right
LtGreen/Yellow=Right

Rear Speakers (if applicable, if you have the amplified rear speakers again the Maximum of 15 watts peak is all the stock speaker amp input can handle):
Brown= Left rear
Brown/White= Left Rear

LtBlue= Right Rear
LtBlue/Orange=Right Rear

 

just run new wires for each speaker, its alot easier than trying to fiqure out existing wiring. most aftermarket stereos will put out 45+watts per channel/speaker, so ditch the stock amps.

 

if yo dont ditch the amps you are gonna have either the amps blow or the deck so just bypass them ,btw if you have bose youll need to replace all speakers as well. bose is the only company to run a mid range woofer at 2.47 ohms this creates problems with 4 ohm after market decks

 

ok thanks. i just hooked it up to the stock wiring. i dont think theres a stock amp. i couldnt find it on either side of the dash. how big is it? i only have front door speakers for now.

 

The factory amps are under the 6.5" speakers in the back, and I believe there is another one beside the 4" speaker on the passenger side under the glove box.

 

just run new speaker wire its alot easier that way and you dont run the risk of messing things up with the stock amps and DONT forget that if you have a power antenna you will have to install a relay because it is a negative trigger

 

every speaker in the rx7 has its own amp(high end models , not sure about base ) as has been said run new wires
