Hey There,
I work in the car audio indusyry, I MANAGE 3 stores... I have the Nakamichi System in mine, my amp went bad... this is all you need to do... Get a 4 or 5 channel amp, run new 4 or 8 gauge wire ... use the 9.6 volt blue and yellow wire from the signal side of the amp TO TURN IT ON OR RUN NEW REMOTE FROM SWTCHED ACCESSORY...THE PLUG YOU NEED HAS has two brown wires, one is brown and black striped and one brown side by side, then the first four wires on the right side has yellow, red and ??? other colors next to them, the first 4 are front left front right rr, rl... they are signal leads and the brown and black are the common isolated gound for 2 wire RCA's where 1 wire is signal and the other ground....... combine all shields from cut rca's to brown and black and now you have 1 volt signal lead--- add a 4 channel ,,,, 2 channels will run to run 4 speakers for the high's and the tweeters in the front doors are crossed over in the doors----- the sub ---4ohm--- is used on the other two channels bridged, you will have no fader except front will be highs and the rear will be subs(or whichever you prefer)... or if fader is needed use a 5 channel amp or 1-4 channel amp for highs and 1- two channel amp for lows.---- rest assured you will have no problem duing this as i used a kicker 350.4 to do this and NO ENGINE NOISE is there..... I have it and it works,,, just meter left ft, right front, r rear, left rear.... splice to rca's and you got it... it works with factory head unit.... every one says it can't be done... yeah-ok.... IT WORKS AND BELIEVE ME IT DOES AS I USED A FOUR CHANNEL SO MY REAR FADER IS ON THE SUB MY FRONTS ARE ON THE HIGhS....4- 4INCH MB QUART DISCUS, KICKER 10" SUB COMPVR NO BOX, SOUNDS REALLLLLLLY GOOD....
