Bronze Member Username: Slayer77None, None non Nnoneoneone Post Number: 13 Registered: Jul-04 | I just got this new amp. I will keep it as noname since it comes from China. On the box it says this: DC-DC 4/3/2 Channel (4ohms, 14.4V) 450W * 4CH MAX 900W * 2CH MAX 100W * 4CH RMS (4ohms, 20hz-20Khz, 0,04%THD) The amp is bridgeable on each of the 2 channels. (Rear = HPF/LPF/FULL, Front = HPF/FULL) I got it for very cheap (20$) hehe. I want to run my two Phoenix Gold 12" XS Series (250W RMS/500W Peak each @ 4 ohms)subwoofers. I was wondering how I should set things up? I tried bridging the rear channel output on the amp. I hooked the (+) together and the (-) together from each sub on the bridge (+) and (-) on the amp (rear). I hooked up the Right/Left RCAs to the rear channels only. http://www.opalcountry.com/carstereos/KENBO/MVC-365S.JPG Settings: (the HPF/LPF is inverted on the pic!!) http://www.opalcountry.com/carstereos/KENBO/MVC-366S.JPG http://www.opalcountry.com/carstereos/KENBO/MVC-367S.JPG How should I set it up if everything is ok? LPF is currently to 80 Hz It is set to LPF not full. The gain is at 1/4. What does that 12-6-0 do? Is it like an EQ sub gain.. 0, +6, +12? Thanks for the help, I'm trying to figure this whole thing out, without instruction manuals. http://www.opalcountry.com/carstereos/KENBO/MVC-368S.JPG Do this mean I can run subs in 2 ohms stereo? How would I do this (be very explicit)? I am a beginner. Phil Laberge |

Bronze Member Username: Slayer77None, None non Nnoneoneone Post Number: 15 Registered: Jul-04 | Also my Digital Capacitor seems to be shutting down (well the Display) when the car is on. It takes about 5 minutes of playing. If I turned the car off suddenly the digital display lights on normally. If I restart the car it lights on again for 5 minutes. Is this a normal auto shutoff function? Is my capacitor defective? It is a Legacy 1.2 Farad Cap. I know, Legacy is bad. |

theAnonymous1 Unregistered guest | DO NOT parallel the voice coils of the subs and then bridge the amp. That will give the amp a 2ohm mono load and it will cause it to overheat or even permanently shut off. Either bridge the amp and series the coils or put 1 coil to each channel. Yeah well, thats all I feel like typing so your on your own with the rest. |

Bronze Member Username: Slayer77None, None non Nnoneoneone Post Number: 16 Registered: Jul-04 | It is already in series and not in Parallel. I just bridged the amp. I noticed the amp becoming excessively hot. I wondered if I had not made a mistake. I connected both (+) from each sub and both (-) to the amp. It is bridged on the rear channels. I was wondering if all was ok. |

Silver Member Username: JayjLouisiana USA Post Number: 471 Registered: May-04 | You can't wire that amp like that because you are giving it a 1ohm load. When you parallel the subs then bridge. You need to run ONE sub to each channel DO NOT BRIDGE. *I connected both (+) from each sub and both (-) to the amp.* This is parallel NOT series |

Bronze Member Username: Slayer77None, None non Nnoneoneone Post Number: 17 Registered: Jul-04 | I do not believe I am in parallel. Sub 1: (+) To (+) on amp (bridge) (-) To (-) on amp (bridge) Sub 2: (+) To (+) on amp (bridge) (-) To (-) on amp (bridge) They are plugged in the amp through the leads on each side from the sub box. I linked them both to the same input on the amp. Rear channel bridged. Is this 2ohm stereo? |

Silver Member Username: JayjLouisiana USA Post Number: 477 Registered: May-04 | Phil if those subs are not DVC then you ARE running them parallel. You should pull up a wiring diagram and take a look yourself. You DO NOT twist wires together at the amp and think your are not running parallel because YOU ARE. And if you are (bridging the then you are running a 1ohm load. 2ohm stereo is when you are running TWO subs one on EACH channel you are running parallel and bridging which is giving your amp a 1ohm load. If you are going to bridge then hook one sub to the front channels and the other sub to the rear channels. OR run each sub on one of the REAR channels do not twist the sub wire together because you are lowing the ohm load. |
