New member Username: Mike20Post Number: 8 Registered: Oct-06 | alrite ive been havin the biggest problems with these alpine x 10 subs.. They just are not hitting as i expected.. at all, with a weird rattle type noise. Im going through EVERYTHING to figure out the problem so.. would anyone know, when running all that power with the mrd1005 alpine monoblock amp to a 10" x 10 if 1. i need Really thick wires 2. Do i need a certain type of box? (sealed, ported, certain size). And last, if its in a sealed box, if it is not Completely air tight will it distort the sub that much? |

Post Number: 9588 Registered: Jul-05 | so that 1 amp pushing both subs ? - thats like powering them 1/2 way i even read a good clean 1200wrms EACH will surely satisfy ur bass craving yep having a leaky sealed box kinda defeats its purpose or being sealed ...... |

New member Username: Mike20Post Number: 9 Registered: Oct-06 | well i heard that that amp is enough to run only one sub, so im trying to get only one hooked up but i have two subs. I just cant figure out why the hell it sounds so bad.. |

Gold Member Username: RovinTrinidad & T... Post Number: 9589 Registered: Jul-05 | dual 2 or dual 4ohm subs ? also a badly made box will make any of the best subs sound like crap ...... |
|
New member Username: Mike20Post Number: 10 Registered: Oct-06 | their dual 4 ohms it says on the bak of the sub.. its a jl audio power wedge box, but i think its got a leak or the sub isnt in there air tight.. Would you happen to know all that about ohms..? Like how do u hook somethin up at 2 ohms, or 1 ohm, and so on. I just dont undertand it.. |

Gold Member Username: RovinTrinidad & T... Post Number: 9590 Registered: Jul-05 | yep ohms r easy 2 follow http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_wiring.html?subs =1 so if 1 sub is hooked up in parallel then ur amp will see a 2ohm load & should be getting 700-1000wrms & sound good enough i dont know specs of that JL box but somehow im guessing its too big recheck HU settings & amps settings like subsonic filter /gain etc ...... |

Bronze Member Username: Mike20Post Number: 11 Registered: Oct-06 | I Probly sound stupid but, since its a dual voice coil sub hook both up? And any certain way? Thanks for your help Rovin. Good lookin out. |

Gold Member Username: RovinTrinidad & T... Post Number: 9591 Registered: Jul-05 | u hook up ur sub like this using BOTH coils yes  i try to do a good deed once in a while - lol ...... |

Bronze Member Username: Mike20Post Number: 12 Registered: Oct-06 | hahh.. Thanks again.. So u think since i didnt have it hooked up like that it could be why its not soundin good at all? |

Gold Member Username: James1115Ct Post Number: 7158 Registered: Dec-04 | yes, if you only had one voice coil hooked up that can be your problem, not wired correctly that could be your problem, faulty box? that can be your problem. You need to go through your system and eliminate one by one till it sounds good. Where do you live? sometimes other members live close and are willing to help others out. |

Gold Member Username: Van_manBoston South, MA Post Number: 1112 Registered: Mar-06 | Ive heard that too^^^^. Some audio shops only hook up one coil depending on the amp to get the most out of it. Say an amp does 300 at 4 ohms and 500 at 2 ohms, then they would only hook up one coil of a duel 4, so that one coil gets the 500. And when/if that coil blows, theres a back up coil. I have read some good arguments on both ways. Pesonally, I wouldnt do it, but ... |

Gold Member Username: Basshead86Try Google Post Number: 7896 Registered: Aug-05 | it changes ALL the t/s parameters of the sub, thus making the power handling, Fs, Qts, and such useless as to what they were previously. you might need a much smaller box with only 1 VC hooked up...and you can risk blowing the sub from that and the reduced power handling... |
