Sorry I took so long to reply... couldn't get my account to work and figured I had to re-register with the new system
This is for my RA65. The battery is in the stock location (passenger side), the amp is going in the driver's side hatch area, and it's going to drive all four of my speakers - two alpine DDDrive 6.5" coaxs in front doors and two older alpine 6x9s in the rear passenger panels.
Is it standard practise to have the amp so far away from the headunit? Seems a long way to run unbalanced low-level RCAs - likewise with the long speaker-cable runs.
