New member Username: BlakktalonPost Number: 2 Registered: Dec-04 | Im pretty smart, and have learned pages of stuff, as soon as i found this cool site. But i still got a couple curiositys. 1. how do you get your car to put out 14.4 to get more wattage out of your amps, or is that just a numbers scam? Secondly, is there a way to convert just one speaker to a 2ohm load, I dont really have the extra money to go out and buy two more infinity 6*9's. and i dont wanna mono the pair if I dont have to. I think thats about it with the sillyness, ill keep reading and offer up advice if I can. thanks |

Secondly, is there a way to convert just one speaker to a 2ohm load, I dont really have the extra money to go out and buy two more infinity 6*9's. and i dont wanna mono the pair if I dont have to. not really. the speaker's impedanec is a fixed vale. the only way to alter load really is by how you wire multiple speakers to the same channel of an amp. if these speakers are rear speakers though, you may want to seriously consider bridging the amp and running them in series, mono. this article will explain why: http://www.wickedcases.com/caraudio/rearfill.html |

New member Username: BlakktalonPost Number: 3 Registered: Dec-04 | thanks for the info, I was just thinking out my next move in my head, but hadnt quite got there. the article helped. Right now I got 65 watts rms *2 but i bridged them one amp per 6*9. so probably 130 per speaker, while the door speakers and tweets are running off the 22rms deck power. I am sure they would love to have the 65 back. |

It was 3am, and I was getting tired. on the speakers, remember if you run one 6x9 per channel on two channels, or if you bridge teh amp and run both speakers together in series on the bridged channel, each speaker gets the same power either way. bridging doesn't really increase the amp's output. It merely puts the full power of a two ohm stereo load into a single 4 ohm load. the drawback is that the amp is only stable to twice it's minimum load when bridged.. so 4 ohms instead of 2. In your case though, bridging just helps by sending a mono signal to eliminate that drift effect caused by bright rear fill. you may be better off powering teh front stage with the amp and just turning down the rears, and powering them from the weaker head unit power, unless you go with a 4 channel amp and power fronts on channels 1 and 2, then bridged channels 3 and 4 and run the rears in series, and fade to the front more to quiet down the rears. |

The 69's are my primary source of bass. the fronts reference 6000i, components are pretty hight on the sound range output. Im gonna try as you suggested, and play with the fade, also adjust the whole thing when im done according to the new info i learndeded. Muchos gracias senor, Glasswolf. Plus typos are commen at 3am so dont worry about it. They are much worse after 3am worth of beers. |
