i have a 95 maxima w/o the bose sound system. i just had circuit ****y install my apline head unit. and insalled infinity. i just wanted to know how to install a 4 channel amp

 

It's pretty easy, First make sure u disconnect the ground wire form your battery, or u could have a bad day, then find the spot where you want your amp, run the proper size power wire (with inline fuse no more then 12 inches from the battery terminal)from the battery through the firewall(you might have to drill) to your amp, also make sure you use the same size ground wire and ground your amp, make sure when doing this u sand down to the bare metal of the place your going to ground your amp. run your remote turn on lead from you head unit to the amp, and also your patch cables from your preamp outputs on the back of your head unit. make sure you keep any and all of your signal cables seperated from any power type wire, including your remote turn on lead, then you could do 1 of 2 things run speaker wire from your amp outputs to your factory speaker wires, or rewire and go straight from amp to the speakers, me personally i like going from amp to speakers, but thats me. ofcourse i didint mention the fact that you will have to take apart some of your interior to get the stealth instalation of all the wires. after all that then you should be good to go just tune the gain and x-overs to your speaks or your liking then your done. I'm sorry i didnt go into more detail but i gotta run soon, if you need more explicit instructions then email me, snyperlystat@yahoo.com... ill be glad to help you out in detail

 

What he said ^^ Good instructions.

 

Excellent instructions! I also am going to add 4 ch. amp to my system. One question, the turn-on wire should go from amp to HU. How can I find our where on HU I connect it?

 

you don't have to run RCA's and power cables seperate.

 

You can run the remote power turn-on from the amp to the power antenna lead on the HU.

 

you dont have to but its a good idea alot of people dont spend a buttload of money on their wire, cables ect, and then find that when they hook it all up and start driving everytime they rev it up they gat a whining noise from their speakers, this has been an easy fix in my experience when my friends have come to me and say what the f$%k is that noise, i look at the ground first then their where the cables were ran, its not a guarantee it will happen, but it does happen

 

yup,yup, power antenna lead

 

i'm running my cables all on one side of the car...and have no whining noise issues at all. most of the whining noises come from a bad ground somewhere.

 

Yes, this is so true. It's always a good idea to seperate power wire and audio cables to risk any unwanted noise. But, people skip this important step and wonder why they have noise! Spend the money and buy high quality SHIELDED RCA's and you'll hardly run into any noise. Secure all grounds on BARE metal, too.

 

the turn-on wire is light blue with a white stripe on it. Atleast it was on my car, probably the same for the other years...
