v8killah Posted February 8, 2008 Author Report Share Posted February 8, 2008 Sorry for all the questions, but if it will bypass the AVIC, how will the reception improve. Also, why is there a lead on the AVIC's harness for it if it could be connected to the red wire in the first place? Thanks No, it would bypass the AVIC all together. Red ACC wire from car to the car's power antenna lead, which basically switches on the power antenna whenever you turn the key on. Quote Link to post Share on other sites
HiFiSi Posted February 8, 2008 Report Share Posted February 8, 2008 The antenna signal doesn't bypass the AVIC. The power going to the antenna booster bypasses the AVIC. It's basically using the car's key as the power switch for the booster instead of the AVIC. The reason radios have power antenna outputs is because if they are used, the antenna booster (or retractable antenna, if that's the case) would operate when the radio is powered on or off, not when the car is. Because you don;t need to power the antenna booster if you're driving with the radio off, but it doesn't hurt. Quote Link to post Share on other sites
v8killah Posted February 9, 2008 Author Report Share Posted February 9, 2008 So, I ended up getting the radio working (finally). It just would not work when the blue wires were connected together, so I connected it to the blue/white wire that my subwoofer amp is connected to. That way, at least if I have the AVIC off, the radio amp won't be getting power; versus the red wire, which would have provided constant power whether the unit was on or off (until the ignition was shut off). Does anyone have any ideas why the blue wire to blue wire connection didn't work? I tested it with a voltmeter and verified that my "solder job" was good. Thanks.

HiFiSi Posted February 9, 2008 Report Share Posted February 9, 2008 FYI, the AVIC is on as long as the car is turned on. You can't power it off without turning off the car's ignition. So in this case, it's the same thing. Quote Link to post Share on other sites
cntrylvr79 Posted February 9, 2008 Report Share Posted February 9, 2008 Like I said about 20 posts ago, the antenna output of aftermarket radios provides a limited amount of current. In some cars this is not enough to power up the antenna amplifier. Oh and as HifiSi said the blue/white wire in the case of the avic acts EXACTLY the same as the red wire.

yamahatundrav8 Posted February 9, 2008 Report Share Posted February 9, 2008 I think the am/ fm antenna on my z1 is weak to say the least and I don't have a power ant on my Tundra. Is there any way's to improve the signal strength? Quote Link to post Share on other sites
HiFiSi Posted February 9, 2008 Report Share Posted February 9, 2008 Buy an antenna booster. Not a very expensive item. http://www.digital-comfort.com/store/proddetail.php?prod=AB150DSF Don't know how good they work, but it's cheap enough that it's worth trying.
