Hey, guys I just brought my X in today to get my speaker upgrade plus sub install at my local guy...I originally thought of mounting the 2 amps on back of the seats, but we found a new spot to mount them...1 in each compartment in the trunk, so everything is completely hidden...the amps fit perfectly in each compartment, i was amazed, and there is plenty of ventilation for each amp in each area....comments welcome, and pictures will be posted ASAP when i hopefully pick up the car tomorrow night as scheduled....
