Pepsi Man Unregistered guest | why is that??? cause the fosgates actual numbers are around 1461 rms at 1 ohm and the jl is like 1000 |

Silver Member Username: Goose5714Post Number: 317 Registered: Feb-06 | cuase jl is a regulated power supply so at all its stable ohm loads it will put out the same amount of power, the fosgate is probably unregulated so lower impendance=more output. I know the w7s have wierd coil configs...not sure what it is but i agree with ^^^him that you can't wire it up for 1 ohm... |
|
MrJuicetin Unregistered guest | yea i know its 1.5 ohms. but even at 2 ohms the fosgate is still at 1052 rms. doesnt that mean that if u do the jl at 2 ohms it will have even less power than 1000? |

Gold Member Username: TjmutlowPost Number: 1577 Registered: Sep-05 | it is only 1052 if it is ran at a certain voltage, etc, and it will not run that for long periods of time.That is peak wattage they got that amp to. |

Gold Member Username: LexuscoopPost Number: 1036 Registered: Dec-05 | the specs on the w7 are SVC 3 ohm... right? you can't get that to 1ohm at all right? or could you but have to buy alot of them |

Gold Member Username: James1115Ct Post Number: 5378 Registered: Dec-04 | no regulated power supply (look it up at www.bcae1.com .) The JL will put out 1000 watts( very conservatively) more like 1100-1200 at any impedence load from 4 ohms to 1.5 ohms. now the w7 is a dual 1.5 ohm sub. Now you can wire that to 3 ohms or .75 ohms which neither amp is stable at so your only option is a 3 ohm load. The RF's output is as follows 500x1 @ 4ohms, 750x1 @ 2 ohms and 1000x1 @ 1ohm. Now the JL is 1000 x 1 @ 4ohms, 1000x1 @ 3ohms, 1000x1 @ 2ohms, and 1000x1 @ 1.5 ohms. The w7 is wired for a 3 ohm load therefore your fosgate will put out 625x1@ 3ohms and the JL will do 1000 x 1 @ 3ohms I would take the JL any day even at 1.5 ohms I would take the JL it is a much better built amp. |

Silver Member Username: Goose5714Post Number: 318 Registered: Feb-06 | w7's are dual 3 (looked it up lol), so you can only wire em for 1.5 or 6 and who wants 6.....the JL as i mentioned above is a regulated power supply, so for like 1.5 thru 4 ohms (or whatever its rated for ohm wise) it will do the 1000 watts, doesn't matter what load it will do the 1000 watts... |

Gold Member Username: James1115Ct Post Number: 5380 Registered: Dec-04 | no they are dual 1.5 ohm |
|
Gold Member Username: LexuscoopPost Number: 1040 Registered: Dec-05 | oh ok, thanks James |
|
Silver Member Username: Goose5714Post Number: 321 Registered: Feb-06 | wait i thought w7's were dual three??? now i'm confused.... |
|
Gold Member Username: LexuscoopPost Number: 1041 Registered: Dec-05 | they are duel 3 but they can be wired for 1.5 ohms or 6 ohms |

Gold Member Username: Jonathan_fGA USA Post Number: 5706 Registered: May-04 | With a 13W7 you're going to have dual 1.5 ohm voice coils. Either 3 ohms or .75 ohm. You're best off running at 3 ohm for either amplifier due to having less heat produced. That RF amplifier will put out around 700W at 3 ohm, while the JL will put out over 1000W RMS. "why is that??? cause the fosgates actual numbers are around 1461 rms at 1 ohm and the jl is like 1000" That's a CES-2006 rating. Meaning 14.4V at a 1% distortion level, not realistic because in a real world application you most likely aren't going to have 14.4V at that point. 1% distortion means the amplifier has already began clipping as well. The JL puts out over 1000 at realistic voltage levels and impedances, typically it's around 1100-1200W RMS. For your application, it's the better amplifier. |

Gold Member Username: Jonathan_fGA USA Post Number: 5708 Registered: May-04 | Didn't see James' post. It's a dual 1.5 ohm subwoofer: http://mobile.jlaudio.com/products_subs.php?series_id=10 |

Silver Member Username: JakeyplaysbassSt. Louis, MO Post Number: 656 Registered: Jul-05 | the 12w7 is dual 3 and the 13.5 is dual 1.5. |
|
Gold Member Username: Jonathan_fGA USA Post Number: 5709 Registered: May-04 | None of them are dual 3. The 13W7 is the only dual voice coil W7, the rest of them are single voice coil 3 ohm subwoofers. |

Gold Member Username: RovinTrinidad & T... Post Number: 6330 Registered: Jul-05 | no need 4 such a long thread cause Lil Jon said it perfect >>>>"1000/1 it was built for that subwoofer"...... |
|
Silver Member Username: SpyderEglin AFB, Florida USA Post Number: 303 Registered: Jun-05 | because the amp is overdriving itself lil jon. i am guessing at 72 it is at max power it can drive....try adjusting the gain down a touch and turn it up and see if it still does it!! but remember at or around 90% percent volume, distortion will be setting in on the lower end headunits out there! |

Silver Member Username: Nnnnick_bNc Usa Post Number: 430 Registered: Jan-05 | Not to mention the 1000/1 does not just put out 1000 watts. Most bench around 1200rms if you electrical system is up to par. |
