New member Username: KpowersPost Number: 1 Registered: May-06 | I am installing one JL Audio 10W7 that should run at 500W RMS. It will be powered by a Kenwood KAC-9152D that should push 500W RMS @ 4 ohms. I am installing into a 2001 Cadillac DHS. Will my factory alternator do the job. Since its a class D amp, is there no need for a cap? any replies or emails - much appreciated. kevin_powers@fhsd.k12.mo.us |

New member Username: KpowersPost Number: 2 Registered: May-06 | amp has followings specs listed: 2 X 30 amp power supply fuses 500 Watts x 1 max (4 ohms) RMS 900 Watts x 1 (2 ohms) RMS 900 Watts x 1 (1 ohms) RMS how do I wire it to run at more than 500W RMS and then would I need an expensive ho alternator? anyone know how the 10" Hypnotic sub compares to a JL Audio 10W7? |

But with 500 rms u shouldnt have to worry about it because thats not enough watts to really do anyting. i have 800 runnin of stock alt, and no problems so i really depends on the car. i would have gotten a better amp too. if ur gettin a NICE SUB, GET A NICE AMP. you would be so much happier because for one, the amp is rated at 14.4 volts and for 2, it wont put 500 out @ 4 ohms. can u trade it in or anything? |

New member Username: KpowersPost Number: 4 Registered: May-06 | no- i am a network engineer for a school district. I am only planning on one sub will the one sub pound with this amp, if not, does any one have a good amp recomendation for one JL Audio 10W7? If I would ever get a second sub (probably not) I planned on just getting aonther amp and sub, probably the same amp and sub. i think then i would probably need a new alternator. |

Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 1162 Registered: Oct-05 | a great amp to power those subs, would of course be the jl 1000/1. i dont know wut ur budget is though... and no the sub will not pound very well with that amp, you want to get absolutley the most out of that sub budget for another amp? |

Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 1167 Registered: Oct-05 | first of all, orion is a great amplifier company and they always put out the rms they say they do. they dont overheat and they are reliable. i would want to put 600 watts into that 10w7 of your because it will sound great. 500 watts (as the kenwood) thats prob. doesnt even put out that means that u will be gettin less that the recc. rms. wut is the configuration on ur ohms, voice coil... |

Bronze Member Username: KpowersPost Number: 25 Registered: May-06 | 3 ohm, not sure about the voice coil |

Gold Member Username: Dustin3Tigard, Or U.S. Post Number: 1171 Registered: Oct-05 | its prob 3 ohm single. i dont know if there is a DVC 3 ohm sub?... if its single 3 ohm just wire it to 3 ohms. thats why a jl 500/1 would work well because u can wire them from a 1.5-4 ohm load, and still get 500 watts |
