How do i hook up the 4 4 ohm interior speakers to a 2 ohm total 4 channel amplifier?? Help please
I have 2 4 inch 4 omh audiobahn speakers, and 2 6x9 4 ohm audiobahn
speakers, i just bought a 4 channel 600 watt audiobahn amplifier. I would like to wire this preferably to 2 ohms total so i can be driving the amp at 2 ohms(150 watts per channel) instead of 4 ohms(75 watts per channel). Also how do i hook up the rcas, do i have to run two seperate rca's? |

If you have a 4-channel amp, and four 4-ohm speakers, then there's really no good way to present each channel of the amp with a 2-ohm load, unless you put two speakers on a single amplifier channel. As for the RCA inputs, some amps will take a single pair of RCA inputs and use it to "feed" all four amplifier channels, or you can use a Y-splitter to turn one pair of RCA inputs into two pairs. With either method, you'll lose the ability to adjust front-rear fading from the head unit. If your head unit has separate preamp outputs for front and rear, you're probably better off using the two pairs of preamp outputs from the deck and running two pairs of wires to the amp. -- Scott Gardner "Evolution is a harsh mistress." |

If you really want to run at 2-ohms, then you will need to dump the Audiobahn speakers and go with something like the Infinity 42.7i (4" 2-ohm) and the 692.7i (6x9 2-ohm)... but I'm guessing they are a bit more money. If you want to retain the ability to fade between the 4-inchers and the 6x9's, you will need to run two separate sets of RCA's. If you don't care about fading out the rears, then you can use a single run with Y-adaptors... but I would really recommend NOT going that route. -- Jethro [(Vas/Vbox)+1]^.5 * Qts or Fs ------------------------------------------------------------------------ Jethro's Profile: http://www.caraudioforum.com/vbb3/me...p?userid=18662 View this thread: http://www.caraudioforum.com/vbb3/sh...d.php?t=228459 CarAudioForum.com - Usenet Gateway w/over one million posts online! |

Remember though, you can still fade it out manually with the gains on the
amplifier.

If you want to just set the levels and leave them, that's fine, but if you want adjust the fade balance regularly, it's not very practical. --- avast! Antivirus: Outbound message clean.

Why is it not good to have the rears run louder than the fronts?
New setup.......... i scraped the 4 channel amp and i bought an 400 rms 2 ohm 2 channel and a 200 watt rms 2 ohm 2 channel , these will be hooked up to 2 6x9 200 watt rms each speakers and 2 4" 100 watt rms each speakers therese also going to be an eternal subwoofer in the trunk with an 800 watt rms amp feeding it, and a 3 farad cap to power it, the sound will be produced with an alpine cd/mp3 player, will this sound good, by the way everything but the headunit is audiobahn |

That should be the goal of a decent sound system... to reproduce music with a somewhat realistic FRONT stage. When you go to a concert, you don't turn your back to the stage, do you?

Rear speakers being louder would be fine if your ears were pasted on
backwards. No, seriously. The pinna attenuate high frequencies. Your effective frequency response of your ears with sound coming from the front is greater than with sound coming from behind you. Here's a test: play your rear speakers alone while facing forward, and then cup your hand in front of your ear. Sound better?

" Your effective frequency response of your ears with sound coming from the front is greater than with sound coming from behind you." so the rears should be louder to make up for it!!

A few problems with that... 1) The amp isn't going like running two bridged 2-ohm loads. not that it matters now but... audiobahn amps list this as a feature and post specs for this very config 2) He will lose all front/rear fading ability. true, just going with what he had at the moment 3) If the 6x9's are more sensitive (typically they are), then the rears will be loud er than the fronts (not good). |
