Since I don't have a radio code. I tried the acura site for the radio code but I didn't get the zip code or email right (bought the car used a few months back).

I'm installing an amp and sub. I'm thinking about hooking everything up except for the Amplifier B+ (Power). Then when I'm done routing all the wires and others, disconnect the Battery Ground and then connect the Amplifier B+ and then connect Battery Ground.

Does the radio reset right away or do I have like 5 minutes before I need to enter the radio code?

 

Nevermind, I just did what I do when I change batteries. I hooked up my battery charger on low and put the power cable on and it was fine.
