I got a website http://www.pac-audio.com/oem1kits/oem1search.htm from
someone who replied earlier, did a little research on that site and it said that if you have sound in the front, but nothing in the rear you need to turn on the rear amps. Looking over the connections again, I found one wire from the harness, and from the receiver that weren't being used, turns out they were the amp "on" wire on the harness, and the power antenna/remote turn on wire on the receiver. I connected them together without a relay, and it works ok, UNTIL I turn it up real loud, or have too much bass in the sound, then the rear channels drop in and out, until I lower the volume. Maybe the amp is getting too "hot" a signal and causes it to drop out? I guess I can use it like that for now, until I can get some new speakers in the back.

most after market radios have a pre amp in them bumping up wattage to say 50
watts per channel and then when u try to run that signal into another amp a thing called clipping occurs and the speaker cuts out . it's a megahertz thing u can't amplify a signal twice Snydley wrote: > I got a website http://www.pac-audio.com/oem1kits/oem1search.htm from > someone who replied earlier, did a little research on that site and it said > that if you have sound in the front, but nothing in the rear you need to > turn on the rear amps.

You most certainly can amplify a signal twice (or even 50 times). It's not a "megahertz thing" at all - clipping is caused by overdriving an amplifier's input capability, based largely on the biasing of said amplifier. -- If you're not on the edge, you're taking up too much space.

This statement is hilarious. You can amplify a signal as many times as you want. Multiple stage amps are very common. "It's a megahertz thing," now that is a classic. Matt |

when you use a scope and amp the signal twice you cut off the freq at the top of
the wave hence the word clipping and you can watch it on a scope it becomes a stright line then drops bac down doubt my words try hooking up a eq after a 2 channel high power radio has been installed and use all high level wires to hook it up Dan C wrote: > On Sun, 17 Oct 2004 15:01:27 +0000, mic canic wrote: > > > most after market radios have a pre amp in them bumping up wattage to say 50 > > watts per channel and then when u try to run that signal into another amp a > > thing called clipping occurs and the speaker cuts out . it's a megahertz thing > > u can't amplify a signal twice > > Well, the intent of your message is correct, although the technical > accuracy is not...

Keep within the capability of the amp and you can cascade several before distortion becomes a significant factor. Matt |
