Radio help before i go crazzzzyyyy please

[koztek55]

okay the problem is...
i have an afetrmarket headunit, with the adapter loom to plug straight in, i have just run through some wires to a 4 ch amp, worked great for 5min, then..... the damn radio fuse in the fuse box blew, put another in, guess what....again, im pretty cluey with electrics, so ive checked almost everything, for shorts, touching wires etc..
The other problem i have is that there is no remote wire on the loom adaptor, i have atached it to the ignition red wire on the loom with no luck, so it wont switch the amp, which works fine.

i spent about 3 hrs trying to search for problems, to the point where i called it a day,driving without a radio is pretty bland, please i hope somebody has some advice as it is one of those small very annoying problems.

cheers,
kosta.

it could be anything and really if you say you checked just about everything, no one is going to be able to help without actually seeing the car, best bet would be to take it to a auto electric

does the stereo do the same thing wen the amps not connected so its just running everything off the unit?

When the speakers are running off the headunit everything is fine, I think I may have shorted the remote wire come to think of it. Where would be the best spot to hook up the remote wire, as the loom hasn't enough power to switch the amp .....

yeah sounds like it, wat head unit do u have? most units already have a remote wire u can use. somtimes they call it an antena wire also which does the same thing.

yer its usually blue or yellow and says REM or ANT
use that
so it runs fine when the amp is off?
what have u wired the amp to?
is it on its own line straight to the battery with a inline fuse?

Yeah 4gauge straight from the battery fused, only radio I have ever had trouble with. It's a Sony

sony? that explains it lol. but they usually have 2 wires 1 blue and 1 blue with white trace but wat is the model number 1st? so we can search the model 2 find out?

id say u already have the wire there u may just need 2 move a wire in ur ISO plug so ur able 2 use it.

lol, yeah im not a huge fan of sony, but i have to say this head unit is one of there better ones.

model number is CD-GTX71W,
any help would be much appreciated, brought it into work today, hooked it up to an amp and 12v battery and it switched fine. it just puzzles me why it doesnt switch when i have it powered in the car, just stays in protection mode, checked again the power coming through to the amp is clean, and the ground is good, so is there another wire that is interupting the loom??????

[koztek55]

*cdx-gt71w

[wrx884]

here u go says u have a blue wire thats ur antena wire and ur remote wire is blue with white trace, thats wat ur going 2 use, that should run straight 2 ur amp 2 switch it on is that wat uve done?

http://www.docs.sony.com/release/CDXGT71W_install.pdf

the pdf even shows u how 2 wire up ur set up easy as man hope this helps.

The other problem i have is that there is no remote wire on the loom adaptor, i have atached it to the ignition red wire on the loom with no luck, so it wont switch the amp, which works fine.

kosta.

now u say this also. The ISO plug may have a spare wire u can use but not needed as the remote wire can b run seperate straight from the unit 2 the amp. make sure u got ur batt+ yellow wire hooked up 2 constant 12V and ur red ACC+ wire hooked up 2 ur igniton.

if your connecting the amp to the head units power it will draw too much current. this will blow the fuse. use an accesory power supply to switch the amp if the stereo doesnt have a switch wire.

Fixed, was getting voltage drop because the cable was getting to hot in the spot that it was in, sorted the power cable out, and everything is fixed thanks guys

too hot? that doesnt sound right if that is the case then ur best up upgrading ur power cable assuming u must b using 8 gauge?

Spoke to a car audio guy, he said where it was running across the front of the car past the radiator, it messes with the resistance of the cable, so I made hole on the brake.booster firewall grommet, ran new 2g cable and it fine
