Hi.
I have a 2003
MCS. Just had the sound system upgraded. Added MB Quart 6.5" in the front, MB Quart 6x9's in the rear. Mounted the amplifier (Hifonics Zeus 8000 5-channel) in the boot.
Problem is, the battery is directly below the amp. This causes a high-pitched whine. Raising the amp minimizes the hum, though not a practical solution.
Waiting to have Dynamat Extremeliner installed under the amp in an attempt to quell the whine.
I've heard talk of people installing the amp under/inside the rear seats. Has anyone done or heard of this?
I searched the forum before asking this question and found no other reference.
Thank you,
MiniBil
