So through together a system for my winter beater 01 Volvo xcv70,
3212 hifonics amp
1 18" fi Btl
Box sub up port back
Big 3, 150amp alt, 0 gauge, voltage drop less then 1.0 typically around 13.4-13.8 on music, it just doesn't get as loud as I would have imagined, this is my first btl (currently have 2 (1) is waiting for a recone, I have had 05 xxx 18" with fi soft parts that just slammed in the past (different vehicle I kno) but it's a night and day difference. Sub is currently seeing approx 1600watts of clean true power. I really enjoy feeling the low notes but also the chest pains from high, as of now the high notes are decent but low notes I feel air more then I feel the bass.
I'm thinking maybe a 4th order or I have the option for 2, I have room for around 16 cu.
Is my current box tuned to high, or am I just expecting to much. Volvo rates v70 with 71.4 cu of cabin space.
