So I drive a small Saturn 3 door coupe. Looking to step into the spl world out of SQ. I am currently running two 12 inch LXR subs from the 80s on a precision power Sedona APA200 and Rockford punch door speakers. It just isn’t loud enough for me anymore. I’m looking to do a not crazy 10,000 dollar spl build. A budget build. Suggestions? Can’t fit anything bigger than a 12 in the trunk but m my backseats do fold down.
