anyone with experience with parallel tuned 6th order boxes? what have been good port ratios? what has been good tuning I'm looking to peak at 45Hz right now i am tuned 42Hz on the low side larger chamber and 114Hz on the high side i have thought about trying and octave above for the high side 84Hz but afraid it might cause cancellation. also thinking about the exact middle of 2 and 3 octaves above 126hz

anyone know anything. i'm doing alright now i just want better 141.x legal 2 10's clamped 1200w out of a trunk not sealed to the cabin. i know sealing it will raise my score but i want to get the best setup before sealing and adding more power.

What are you peaking at? What does your current design look like?

car peaks at 45hz and the box peaks at 45 when tuned to 42hz on the larger side. the box is somewhere around 5 cube total a 1cube side with 91sqin of port tuned to 114hz and a 4cu side 8in sono tuned to 42hz the subs are inside the box facing the 1cube side not enough clearence to turn them around. im using bbp6 to calculate these. i was thinking about decreasing the high side to .5cu uping the tuning to 126 and change the 8in sono to a 9.5in sono same tuning. this is facing forward into the cabin once the box is where i want it i plan on sealing it to the cabin and adding more power.
