I'm planning to upgrade the stereo in my base '09 WRX and will need to be able to fold down the seats occasionally for extra storage space, so back of the seats won't work for the amps. Has anyone successfully installed their amps beneath the front seats? If so, how did you mount them?
I recall seeing one thread where someone mentioned that there are air vents there which could lead to overheating when the heat is turned on. Is this an issue on the 2009?
Also, on the subject of amps... I was originally planning to use a 4 channel amp, bridge two channels to power the sub and use the other two channels to power the fronts and run the rears off a Kenwood DNX6140; however, in order to get 250-300 watts to the sub, I will need a stronger amp. Any danger of overpowering a pair of Focal Access 130 A1s with 125-150 watts? They are rated 6-50 watts, max of 100. I always thought underpowering speakers was more dangerous...
