[QUOTE="hispls, post: 8602400, member: 614752"] You may not be tuned where you think you are or it may be some other factor at play. If you're interested you should plot an impedance curve of your subs in box in vehicle. This is mine, and as you can see tuning is right around 43hz. The correct tool for this job is DATS but you could simply use a DMM and some graph paper and test tones or a frequency generator. OR figure out your TS parameters and box specs and throw them into the circuit I posted above.
