Stock Trans Am Monsoon System

is there a way to turn the bass up on my stock monsoon system my bass isnt to loud and i had it up to the max on the radio i dont feel it vibrate but i can see my mirrors move

no. The monsoon uses the rear speakers as "subs". I've replaced those with audiopipe 6.5 midbass drivers with decent results. for that kind of price you may as well go with a stealth box IMO
