Silver Member Username: Iufan4lifeulPost Number: 653 Registered: May-05 | 1 15" avalanche in a custom ported box with 5 cubic feet tuned to about 26Hz powered by a Kicker 450.2 (500rmsX1) amp. I know it is hard to tell but what Would I look at hitting? Will that be a lot louder than 2 RE12's sealed with the same amp(what I am running right now)? |

Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 1183 Registered: Sep-04 | actually 140-144 i forgot it wasnt getting full power. |
|
Silver Member Username: Iufan4lifeulPost Number: 654 Registered: May-05 | that is still pretty damn loud isn't it? I mean I am used to smaller systems. How would that compare SPL wise to my 2 RE12's sealed? |

Gold Member Username: Addicted2bassMiami, Florida USA Post Number: 1017 Registered: Nov-04 | yeh anything over 130db is loud. Since its only getting full power, i think it'll be as loud as the re 12's..Only reason is because the 12's have more surface area and getting full power compared to the avalanche only getting half the power it needs. |

Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 1447 Registered: Mar-04 | why not try the 2 RE12's vented? (you already have them, so all it would cost you to build a box would be ~$35 and time) |

Gold Member Username: InvainMichigan United States Post Number: 3987 Registered: Aug-04 | "actually 140-144 i forgot it wasnt getting full power." You must be psychic.... People really need to stop guessing how many decibel's a system will hit. I've said it a million times, it's impossible to guess. Quit worrying about it and go get metered. "1 15" avalanche in a custom ported box with 5 cubic feet tuned to about 26Hz powered by a Kicker 450.2 (500rmsX1) amp. I know it is hard to tell but what Would I look at hitting? Will that be a lot louder than 2 RE12's sealed with the same amp(what I am running right now)?" I know you want to get the best for your money, but again, it's impossible to say. Just buy something and try it. It's all you can do. |

Silver Member Username: Iufan4lifeulPost Number: 664 Registered: May-05 | How would the 2 RE12's sound in a 2.5 cubic foot per chamber box tuned to 32Hz? Would that be a good amount louder than my sealed right now? |
|
Gold Member Username: InvainMichigan United States Post Number: 3992 Registered: Aug-04 | If your going from sealed to ported then yes you'll generally have a db increase. Either setup is gonna sound good though. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 1451 Registered: Mar-04 | try a 3-3.5cuft box tuned to 32hz w/ ~30-40sq inches of port. (both subs in the same chamber) that should be louder than your current sealed boxes...if not you dont like it, you'll only be out ~$35 max. |
|
Silver Member Username: Iufan4lifeulPost Number: 665 Registered: May-05 | How do you get the tuning? How do you get it to 32Hz. Can someone get me dimensions for a box with 3.5cubic feet total (for 2 12"'s) tuned to 32Hz? THanks! |
|
Silver Member Username: Iufan4lifeulPost Number: 666 Registered: May-05 | And I thought putting both subs in the same chamber was bad. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 1453 Registered: Mar-04 | how wide can your box be and still fit in your trunk? if it will fit...try 14" x14" x40" box w/ a 13"x2" port 18" long. (in an L-shape) |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 1454 Registered: Mar-04 | both subs in the same chamber is just fine. plus you are runnin both subs on the same amps (bridged?)...so both sub is getting the same signal. |

Silver Member Username: Iufan4lifeulPost Number: 667 Registered: May-05 | no, the amp is running stereo. When I Switch the positive on one with the positive on the other channel then the amp goes into protect at about half volume. Any ideas. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 1457 Registered: Mar-04 | it goes into protection??? those RE12's are DVC 4ohm...rite? and you have them wired series parrallel...rite? your amp should see i 4ohm load if you have it wired like that...bridging the amp should be no problem. make show your bridging the amp correctly... "When I Switch the positive on one with the positive on the other channel then the amp goes into protect at about half volume. Any ideas." ^^^that statment confuses me...lol |
