PSI platform 5 18 fully loaded every option they offer and then some! Direct 4g leads with knu koncepts ofc 4g wire, 4 coil, cf cap, high roll surround, dual true 1ohm coils, ti basket, motor weighs over 100lbs!!! These are super underrated at 5000wrms but if your system is running clean power they will handle 8000rms daily per sub!! These subs aren't even fully broken in yet so I wouldn't start beating on them right away.I ran them on good clean electrical, B2 M1u with 9 runs of +/- 1/0 ofc wire, x5 xs d7500, x6 runs of 1/0 ofc front to rear and x3 singer 270 hairpin alts. My H/U and amp were both tuned with SMD meters so it was all clean power and never close to clipping plus i only had the amp maybe half way up if that cuz i was still breaking them in. These subs are built to order and the wait to have one of these made is 8+ weeks! If you have any questions please just ask and I'll get back to you soon as I see it.
