Hey guys, im new to the first post here. Im new to the forum and I just got a JL Audio CP112-W0v3 12" slot ported box and a JL Audio JX500/1D amp. The guy that installed it told me to leave the EQ on the headunit at flat. but quite frankly it sounds like factory. I didnt pay $700 for factory and personally i think that is BS. i cranked the EQ up a lil and boy what a difference. this thing is niceeee. my question is, will this damage it? and do you guys have any idea how i could fine tune it to protect my investment. Oh and btw i have a JVC KWR710 head unit in a 2003 Impala. Thanks in advance.
