New member Username: Chasing_shadowsPoplarville, Ms Usa Post Number: 1 Registered: Jun-04 | OK peeps, Im new to the multichannel amp thing and i have 8 speakers i want to power off this amp. No subs will be present in this system. What i want is to have the amp at 2ohms. I have 2 5x7 bostons and 2 pioneer 6x9s for the rear. For up front i have a total of 4 speakers. Will this amp run them all? All the speakers are midrange and highs. Thats it. Does anyone have any wiring suggestions or diagrams that can help me with this? |

Does some one know if i can carry this out without using subs. All my speakers are rated at 4ohms. I would really appreciate some imput from some of the forum members. Thanks Guys www.termpro.com/articles/spkrz.html |

I do know that that amp is very powerful so make sure your speakers can handle that kind of power. I have a kx400.1 and it pushes my twelve with no problem, these amps are very powerful. |

I have found an alternate diagram that will put my stuff at 2 ohms. Have some bostons, seperates that im going to try at 2 ohms. I think they can take it. They have built in crossovers though. |

New member Username: Chasing_shadowsPoplarville, Ms Usa Post Number: 8 Registered: Jun-04 | After 16 hours of sun, heat, sweat, insects and cursing my stereo is complete. Its loud and clear. My box for the rear encompases 2 6x9s and 2 5x7 bostons. I thought i would never finish. Managed to fit all this stuff in my 93 mr2. I havent figured out where to mount my amp because its so long. For now its behind the passanger seat. I havent put the cover on the amp yet because it wont fit! Im considering moving it under the hood but i want easy access to the gain controls from inside the car. Ive got a testimony to give on bostons out of all this. While i was mercilessly drilling into my door metal I slipped and plunged the phillips head bit into my lovley boston componet set spearker. The speaker twisted up like piece of tissute. After reversing the drill my speaker sprung back into place. No tears present. Had to use some rubber cement to glue the surrounding speaker down! It worked like a charm and still sounds unbelievible. Thes bostons are probably 10 years old! Im glad its over with! It was worth the investment in time. I would like to thank the board for providing the knowlege base to make it possible. Thank You. Mark Howard |

Bronze Member Username: Chasing_shadowsPoplarville, Ms Usa Post Number: 11 Registered: Jun-04 | So if the speakers are 4ohms each with two diff sizes such as 1 5x7 and 1 6x9 in parralell they are not at 2 ohms at the amp? I know the frequencies are set the same at the amp side. Are you reffering to frequencies the coils handle in the speakers themselves? Ill consider under the hood. Just when i thought i was done. lol |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 3968 Registered: Dec-03 | by the way that's not a bad thing per se.. it just means don't assume the power output to each speaker as a given. It's not likely to cause problems though, in and of itself. I've run as many as 14 speakers on a two channel amp, properly crossed over for each set of speakers.. it's jut a matter of knowing how to set up the passive filters when you load down an amp that much. |

Bronze Member Username: Chasing_shadowsPoplarville, Ms Usa Post Number: 12 Registered: Jun-04 | So im safe with the setup as it is? Or do i need to rewire my speakers? Thanks, Mark |

Bronze Member Username: AudiophileOFallon, MO USA Post Number: 56 Registered: Jul-04 | well from what I've gathered, you have pairs of each set of speakers. So, wire each pair of speakers to 1 channel. This way, each speaker pair, being the same, should take each channel down to 2 ohms...should. Correct me if I'm wrong, Glass... |

Bronze Member Username: Chasing_shadowsPoplarville, Ms Usa Post Number: 13 Registered: Jun-04 | So instead of running one 5x7 and one 6x9 to one channel I need to run the two 6x9 to one channel and 2 5x7 to the other channel to get the two ohm load thats desired. |

Bronze Member Username: AudiophileOFallon, MO USA Post Number: 63 Registered: Jul-04 | Hey man, if Glass says you're fine, you're probably (99.9%) fine. What I gathered from Glass' earlier post was that having different sized speakers on each channel wouldn't level each channel to 2ohms. Maybe I gathered wrong--I don't know. |

Bronze Member Username: Chasing_shadowsPoplarville, Ms Usa Post Number: 14 Registered: Jun-04 | No thats what hes saying and I understand. I just hate to wire the 5x7s together on the right channel and 2 6x9s on the left. Its not like im overpowering the amp. I dont think im below 2 ohms. I think the amp can handle it without worries. Im just glad its done for the present. I was looking for good clean power and ive found it with the help of the peeps on the board. Again I apreciate all the help ive recieved from the board members. Thank you all! mark |
