Silver Member Username: MoorezySt. Catharines, Ontario Canada Post Number: 169 Registered: Jun-06 | So i just setup my new stuff which consists of.. a hifonics 1606D, kicker 1/0 gauge wire kit, big 3, new H.O alternator from db electrical, four pioneer premiere TS-1207D2 wired to 1 ohm. And of course i had already built my enclosure.. or so i thought... i install everything... i play music... and the subs.. move... but sound seriously wack. like not loud at all.. so right away im like okay. settings on amps. i fool with gain just a little. they get a little louder.. but no air is coming from my port.. 5" wide 25" deep 14.5" high.. i eliminate electrical problems after checking ground and cables. so i narrow it down to my box. or the position of my subs from a friend at a local car audio shop. He thinks the box is too large. or port volume is too much. I disagree on the box size. but i do agree with the subwoofer position and port volume for that box. long story short i am going to have to build another box. I wanted some imput on the volume..tuning or if someone could do a design box for me that would be awesome. the dimensions i can work with are 14" tall, 27" wide and 37" wide. Here are pics of the old box.    As you can see the way the subwoofers are facing we were thinking it was canceling the sound or whatever. so in this design i would probably be aiming for all four facing up port towards trunk. Any help would be great i want to get this new box made and i want to be slamming in a few days  |

They will also design the box in autocad and sell you the plans and cut sheets....look http://fishercustoms.com/services.html |

I would try the old battery test before building a new box! |

Email Post Number: 4293 Registered: Nov-05 | don't really matter.. either way hell get cancellation even if they are all on the same plane.. use a DMM and test the final load.. i really think something is up with the wiring.. unless a sub is mislabeled.. or you have d4s and not d2s |

Silver Member Username: MoorezySt. Catharines, Ontario Canada Post Number: 171 Registered: Jun-06 | the wiring is correct i used a meter to test. and they are its 1 ohm load. like my port is just one straight piece. no L shape. i think it might be something to do with port length and port volume. and the cancelation. like i said. there is no air coming from port. and the subwoofers are full excursion. just doesnt sound right. im powering 350 each maybe more ^^^ i say hifonics 1606D above and i have big 3 and 200amp alt. More or less im building a new box and i need some input for designs this is what i came up with so far.  That gives each sub 1.75 cubic foot each. i dont know the tuning im guessing 32-34 because i got the volume from kicker cvr12 specs of 12.5"x2.5"x20" and multiplied that volume by 4. |
