[QUOTE="Spkrman, post: 1101225, member: 548682"] Tests done with an orion 2500d running at 14v, voltage drop never below 13.5 Pair of big interstate workaholic batteries, stock alt. Vehicle is an 85 s10 blazer, rear seat removed. All tests done with the drivers door open. The sensor is under the passenger dash MECA style. ~~~ SPL PORTION ~~~ SoundSplinter RL-P 12 2500d @ 2 ohm (dual 4 ohm driver in parallel) 2.35 @ 35hz --- 140.6 volume 25 freq 40hz :/// sub showing much struggle, at mechanical limits 139.6 volume 25 freq 55hz :/// sub showing much struggle, at mechanical limits ---- 2.35 @ 45hz ----- 143.4 volume 25 freq 55hz :/// sub showing much struggle, at mechanical limits ----- Alpine Type R 12 2500d @ 2 ohm (one coil on a dual 2 hooked up....
