hey guy, been lurking the forums for awhile i have a 3IS is350 with mark levinson speaker system. Just wonder if it's possibly to add an external subwoofer to the car. I really like the clarity of the sound system but i feel it lacks bass, the setting are very limited and when i adjust the bass on the system i feel it distorts the sound and is not as clear. I would love to have a little more bass coming from the rear. Any feeback as to if it's possible to add a subwoofer would be great.

Yes. You can tap into the speaker wires in the trunk and add an amp and sub with amp control switch

i agree with the above post. also most amps these days will signal sense to turn the amp on, so you dont even need a amp turn on lead. when it senses a signal it boots up automatically.
