This layout is similar to mine, but the amp is a silver colored small amp in the rear driver's side (left side) of the trunk/boot
I'm just trying to figure out if the amp is JUST a sub amp, or if it's more... I was told at one point that the interior speakers are powered off the head unit, and the subs are powered off the amp, but I'm trying to verify... if it's more, it'll make it easy to power the system with a better 6-ch amp in the trunk and maybe a DSP unit... if the amp is JUST for the subs, I'm going to have to fish wires throughout the car to add an amp
HiFi
The HiFi system was standard in US-spec cars until MY 2010 (when it was replaced in some cars with base Stereo) and again starting in mid-2011. There are tweeters and an amp, but no graphic equalizer settings in the head unit’s user menu. The amplifier has analog inputs. Pre-2010 HiFi amps are large black modules. 2010 and later HiFi amps in E9x vehicles can be small metallic-colored modules.
