By the way im new so Hello! and ill be around here for a long time as i am in Love with my SSS, anyway it needs some BASS, and im going to install a box under the seat with 2 12" Kicker Comp VR's or Alpine Type R's and an Alpine PDX 1000.1 mono amp (speakers wired to 2 OHM), i used this identical system in my last vehicle and loved it, what i want to know is if the $15 line level converter that i got at Best Buy to connect my amp to my stock head unit will work out good, im not looking to win any bass off competitions, i just want some bass for my own pleasure, do you guys think it will sound good and have enough adjustability (adjustments on amp and stock deck) to sound right. I am curious if anybody else has done this and how it worked out, my stock BOSE system sounds so good i dont want to install an aftermarket head unit and hard wire all of my speakers + lose my steering wheel controls, on star, xm, etc. so will this be good enough- and remember i wont have much money in it and ill do it all myself, i love projects like this, i just wanted to get some opinions and i searched for a post to help me and couldnt find one,- ok guys what do you think?
