Hey everybody need some advice. I was wondering if I could add subs to my car without going through the hassle of buying a new cd player. I already have the subs and an amp. I have a 2005 gtp with the monsoon sound system. I love the sound I have now but I would really like a little more bass. I'm not looking to be heard a mile down the street so is there another way to get more bass? I noticed there is a little amp in my trunk and I didn't know if I could tie into that somehow or if that will just ruin it. Any help would be appreciated.
