  1. 42552aa7.jpgthis pic is the 28hz port it is 6.25in tall, 30in wide, 35in deep.but only 15in of it goes into box. it is shaped like a L, when i remove the 28hz port it becomes a normal sub up port back box tuned to 43hz port is [7.75in tall, 31.5in wide, 11in deep. 43hz port has 8in from back hatch to breath.

    internal box volume before sub and port displacements is 17.8, outer mesurements are 23in tall, 45in wide, 36in deep. double baffle, dowel bracing

  2. I have 3 18's and 9k of power! my box is 15 cu ft after all displacements tuned between 27 and 28hz 12in of port per cu ft. my peak frequency is 43hz. why do I peak so high when I'm tuned so low?

    the 28hz port is removable, when I take it out, my box is 15.5 cu ft tuned to 43hz 16in of port per cu ft. still peaks at 43hz but 1db quieter. shouldn't it be louder since its tuned higher and more port area???

    I can get up to a 149.6 on a term-lab. should I be hitting better numbers with my setup? should I build a better box???? any tips on how I can build a better box? (enclosure volume, port area, tuning)

    equipment is 3 dc xl 18's on a dc 9k, 2 330amp singer alts, 3 kinetik hc2400s, 2 hc3800s,with 6 runs of pos and 4 runs of neg 1/0 gauge

  3. I had this happen with my 04 envoy. The alt is regulated internally by itself so its not like the newer vehicles where the ecu controls my voltage output on the alt. The problem mine had is that the ground from my battery to the engine and frame was getting rusty. Everytime i cleaned it up, my voltage would come back up to 14.9v warm but when it got a little bit of rust, it would start to drop back down at 13v. I also noticed a random "dancing" affect of my volt meter in my dash when i first started my truck up. The voltage would go up to 14.4v but drop to 13, go up, back down, and then stay steady. As soon as i fixed the ground it worked fine. I would just double check your positive and ground wires in your engine to make sure they have no corrosion or rust on them and go from there.

    Mine was extremely sensitive to rust and would screw up my charging system a ton with it.

    all connections tight no rust

  4. I dont know if you did this or not, this is only something to consider, but when you first checked it was your air conditioner NOT on in your car and it is now? Because that load usually lowers the voltage. Just something to think about if you have an added load on the vehicle now when it's running.

    voltage stays the same with ac on and off. maybe changes by .1v

  5. At the same time, you realize its 100+ degrees here, not sure what it is where you're from, but I would imagine that might also effect it.

    summer here is 75 80 tops. winter is 30s almost never in the never in the negative degrees (maybe on a super cold winter nite) last september alt and batts were reading 14.7 u think after running in cold weather for 4-5 months then when the weather warmed up it changed my charging voltage???
