Orion 2500d: four 10s versus six 10s on one amp.

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 105 Registered: Jan-05 | If i leave the Orion 2500d (2500w RMS @ 1ohm) the same what difference will there be between these setups: Four 10" DVC MTX 81044a @ 1ohm or Six 10" DVC MTX 81044a @ 1ohm Essentially i would have more surface with less power running six. Does having more surface outwiegh having more power? Please correct me if i am wrong: four 10s @ 1ohm on 2500w = 625w per sub for 40" of total sub surface. Six 10s @ 1ohm on 2500w = 417w per sub for 60" of total sub surface. Which is better? |

Silver Member Username: Riebread77Post Number: 331 Registered: Jun-05 | yes that's what it boils down to. If you run 6 of the 10's...then u should have at least 3/4 of the rms...if that isn't attainable, go with 4 10's | |

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 110 Registered: Jan-05 | the Subs are 400w RMS (http://www.mtx.com/caraudio/products/manualsQuickInstall/subs/T81044A.pdf) My question is: are six subs are less power better than four subs at more power. The installed four are currently wire to 1ohm Goal is 60% SQ and 40% SPL The Orion amp is 2500w RMS @1ohm (at least thats what the manual says though i am not convinced) |

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 112 Registered: Jan-05 | so is it better to have four DVC 400w RMS 10s @ 1ohm on 2500w = 625w per sub for 40" of total sub surface or Six DVC 400w RMS 10s @ 1ohm on 2500w = 417w per sub for 60" of total sub surface |

Silver Member Username: Riebread77Post Number: 355 Registered: Jun-05 | if it's 2500w rms...go with 6...your SQ will be jeopardized if you give it 150% of its rated RMS. | |

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 116 Registered: Jan-05 | yeah thats what i would think but currently i have four of the subs wired to 1ohm on the Orion 2500d. That should give me 2500w or 625w each but when i turn my alpine 9833 to 30 it gets loud but the MTX81044a subs do not give any sign of problems... In fact at the level i have already fried an infinity 1001 tweeter (part of the 6000cs component set) which is hooked up to a Rockford Fosgate 301s delivering 75w RMS to speaker that can handle 90w RMS |

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 117 Registered: Jan-05 | hence the note doubt earlier whether the Orion truly hits 2500w at 1ohm... | |

Silver Member Username: Riebread77Post Number: 360 Registered: Jun-05 | might want to turn the gain down on the rockford amp then...clipping is a serious destroyer of tweeters. | |

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 122 Registered: Jan-05 | i adjusted the gain for each of the four sets (two pair of 6000cs; one set in each door) seperately then as a pair with all other speakers off... i did not hear any distortion; even loud it was crystal clear. I did however spell something that i could not place my finger on...even after tracing every wire... Since it was the drivers side door tweeter that fried the smell was very noticable...it took about a week before it finally stop producing sound... once removed the tweeter was bubbled and the rippled on the circumfrence (?sp) of entire bottom... |

Silver Member Username: InvictuzSeattle, Wa Usa Post Number: 123 Registered: Jan-05 | i will adjust the gain a bit tomorrow... | |
