Well, time to start thinking a setup that will do a decent number. I have an hd315 in 3.5 cubes tuned to 38hz running 1 ohm on an Autotek mm1400.1 in my 2002 Acura TL Type S. The problem with these cars...the rear seat doesn't fold down. It only has a skipass that will fold down and a stock sub on the rear deck, which I removed. I got metered today on one of those SPLMeter brand meters. OK, laugh away but these meters are within 2db's of a Termlab. Once I hit a 145.2 on it and when I metered on a TL, got 144.1. My buddy did 143.8 on this "cheap" meter and actually did a 143 flat on the TL.
Anyways, I did a 141.7 on my current setup on this cheap meter so I'd say about a 139. I need more. Question is, can a skipass be used in the same manner as a blowthru setup? My plan is two 12's, each in it's seperate enclosure, on each side of the trunk with both subs facing each other. What are your thoughts?
