Ok so just got a small sub from a friend and it has an amp remote cable.
What is this for? its the only one i dont have a clue about :embarassed:
Where do i have to connect it too :embarassed: Its a thin (same as the speaker cables) and blue :smiley:
Thanks
-
...in which case it must have an amp built in.
It connects to the blue remote wire from the back of your headunit.
-
sorry forgot to say :angry: yea its an active sony xplod :smiley:
i dont have a blue cable on the back of my head unit so will it matter? Do i still need to wire it to anything or just ignore it?
-
You should have a remote wire of some description - it may be labelled rem or ant, and may not even be blue - but if you don't connect it, don't expect too much sound from the sub!(it switches it on).
If you really can't locate the remote wire, connect it to an ignition or accessory live.
-
yeh that blue cable activates the amp. It works on (+) feed
What sterio do you have?
Some people wire it to the rear lights. So when they turn the lights on - the amp turns on
-
Atm ive got some nafo tape player :sad: gotta wait till saturday to wire up my pioneer one :undecided: (which defo does have a blue cable)
1. So it wont work at all without that connected to something?
2. I wont need a switch on the main power cable to turn the sub on and off (to stop the battery draining) as that cable does it for me when i turn on the head unit?
3. Could i wire it up to the power cable until i get my new head unit in?
sorry for all the questions im just trying to see what options i have atm :undecided:
-
Ive just been looking at some amp wiring kits and i know they proberly arent the best cables the kits seem to have every cable that i will need so i think im going to get a kit and see how it goes tomorrow :smiley:
-
1. No
2. You wont need a switch and yes the once the remote on or elec aerial wire is connected the amp
will/should go on and off with the head unit
3. I wouldnt wire it up to the power cable as it would be on all the time but you could wire it up to a switch
or something similar that could be switched off at the same time as the radio or the ignition.

Cheers mate :smiley: going to an audio shop in the morning and going to get an amp wiring kit.
Ill try and find a pull off conector to use as an on off thing for the sub as a temporary fix til the weekend :smiley:
thanks for you help bud :smiley:
heres a naff pic of the sub/amp

Fair play, good luck and regarding a wiring kit I would get the best you can afford (without going mental of course :laugh:) and any install is only as good as the way its fitted and set up :wink:
-
Thanks ive got about £40 so i'll spend it wisely! i suppose if i get this bit right now, then when i get a better sub i will be able to just plug the new one in with the cables i lay now :smiley:
Found the installation manuel for the sub (says on the side Sony xplod XS-AW200X) I know its an old one and only 8" but works and being a student i dont have loads of money. :laugh:

When using a car audio without a remote output, connect the remote input cord to the accessory power supply of the car
Might sound thick but whats the accessory power supply? is that just the main power cable i said about connecting it to?
-
dude....stop wot your doing....u do not need to get a switch!!!
a remote wire can be any grade of wire...there is no quality loss...it does just act as a "switch on" lead.
If you have a sony, pioneer, alpine, jvc, panasonic, even ripspeed and many others that come with a separate power cable with 2 ISO plugs on, then u can patch ur remote wire into the blue indicated wire on that wire.
Any other radio u have whether its blaupunkt,clarion...even the LG units or a radio that does not have its own separate power lead...but has a ISO plug ready for it to plugged in on the back of the radio (provided the car has ISO plugs) will still take a remote lead...but u have to patch it into oneof the cables on teh factory wiring loom for the radio...
If you find your car wiring plugs are separated by means of speakers and another for power supply, then that is easier to work with.
you basically want to use a multimeter/voltage tester to see which cable is LIVE when the radio is on only...so to test...illiminate the original car LIVE's that power the radio which is permanent and ignition wires...(do this before the radio is plugged in..n if ya like..mark em so that u know after!
the ground cable will be located below one of the stereo LIVE's furthest to the end of the block.
so that will elliminate your earth and 2 powers.
Now you have maybe 2 or 3 spare cables to play with. Plug in the radio and then turn it on by means of ignition and everything so that the radio is powered up. then test any of the spare cables to see which one is LIVE also. once u get a LIVE reading of average 11/12.96 etc... then by leaving the ignition still on...turn the stereo u have OFF from the STEREO ONLY (NOT THE IGNITION)
Once you have done this, you should find that the LIVE reading you got is now back to "0"...that has then located your remote wire of which you want to patch your amp remote wire into...by whatever means you want whether you use crimp locks...but you must assure you dont chop the wire completely as it needs to still contact the pin its attached to from behind the radio by means of the ISO block.
In essence, power is coming from the radio when it is "ON ONLY" back down a cable to activate possible electric car aerials...if you have one...otherwise left spare as an optional extra or to cater to activate sumthing else..but nevertheless, that is the wire u want to patch your remote into!
hope all this makes sense. If your at any point confused...then holler back n tel me where your stuck!
Goodluck

Am I wrong in thinking you can just use any 12v source for this? Why does it have to come off the radio, couldn't he take it off the ignition or the fan blower controls?
-
yes can be any 12v source but as you want the amp to turn on and off with the headunit it just makes sense to connect it to that
you can run i wire direct from battery with a switch if you wanted but is just easier to go from headunit ;)

yea mines kl as it is but a pain having to disconnect it in the boot :embarassed:
Going to wire my head unit 2moz and if my dad wont help ill task it myself (having done 2 subs in 1 day has given me a confidence boost :grin:)
Ill then wire up ye olde blue cable into the head unit and save the fafing with unscrewing the power cable :rolleyes:
-
DO NOT wire it to a constant 12V power supply..unless of course u want to discoer the next morning your car will not start due to a drained battery!You could almost get away with wiring a remote to the ignition switched power supply but i still would not do that. it is so much easier just to wire it to the remote output from the radio...makes sense and is the proper if not recommended method of installing it!
refer back to my previous post for details on how to do this!
Leme know how u get on :cool:

yer not to be rude mate but you need to re-read what i have said.
As i have said in previous posts:
1. On my current head unit, i do not have anywhere to plug that remote wire.
2. I said in my last post that I have disconnected it in the boot when not in use
3. I am wiring in a new head unit tomorrow which does have the blue wire and therefore will solve the problem with unplugging it etc...
-

Some people wire it to the rear lights. So when they turn the lights on - the amp turns on
the above idea is NOT recommended! If theres anyone out there that uses this method, then they're probly kickin themselves in the back questioning there approach and perhaps have changed there method since!?

I see, and i did also read that too, but its a pain having to disconnect it everytime now isnt it??
You shouldnt expect a place to plug the remote wire into behind the head unit...u have to patch it into one of the wires as commented before. whether by means of cable locks or, strip down the insulation on the identified wire from the head unit that activates upon the radio being on...(not ignition) and loop the end of ur amp remote wire through it so that it does not involve having to chop the head unit or car wiring loom!

yea but disconnecting it was good enough for one day.
There is a place on my new head unit so whats the point in patching it? I also wired a sub for my friend today and his was the same with the blue wire already there. Even the manual stated thats where a sub remote wire gets placed (didnt get a manual with mine) Do you have any knowledge of new headunits???
-
alrite, i confess....i work as the ripspeed specialist at halfords and take care of all the audio/satnav dvd fittings etc..
so i would say i'm pretty comfortable with the knowledge of both old and new head units. Just tell me the make n model of your frends unit and i can tell you how to my knowledge it can be done...but again..if there is no indicator for remote on the stereo wiring loom that it comes with..then it will mean having to patch a remote in...doesnt take long at all! :cool:

no thats what im saying it DID have the connector. You seem to think that they all need patching but the head unit ive got came with an ISO adapter that already has it and all i need to do is plug the blue cables together. ONLY reason i have not done this is because i have to wire the iso connector in and want my dad to do a proper job about it.
no offence but my experience with the halfords staff near me are really really stupid. Just like the people in pc world have no idea about pcs :rolleyes:

yes..PC world/dixons/currys/mastercare..all seem to have problems..i identified this wen i was working for that firm. lack of appreciation for there staff.
anyway..back on subject...i have come across halfords staff where the lack the knowledge of these things but i assure you i am quite comfortable with job. its just perhaps i'm having difficulty understanding what you mean by "having to wire your new radio ISO loom in"
has the wiring in your car been compromised and chopped at some point then?? are you refferring to a hardwire? as thats what it sounds like!?
-

sorry mate i though i made it clear :lipsrsealed: guess not!
Yes i am having to hardwire it in. My car is 17 years old and has been subject to someone hardwireing an adapter in.
I took my car to halfords and another couple of places looking for an adapter for the connector in my car and was told at 3 places that i would need to wire it in myself (the adapter i got with the head unit)
Ive got a plug that should go on a standard VW plug behind the head unit but that one has been taken out at some point along the line.
I know how to wire it in. I have the speaker cables, 3 power cables and the blue remote wire.
Cheers for your help and sorry i was rude last night :embarassed:

its kool dude...so er....u didnt mention wot make stereo u had then?
So from wot ur telling me now..u have what i no is a "PC3-08" bare end ISO lead:
http://www.incarexpress.co.uk/catimages/accs/iso.jpg
Once u have wired this in....(remote is not important to patch in at this point) then u can simply just plug in the loom which came with your radio into this e.g:
http://www.geocities.com/exclusive_part/ken16-iso_3.jpg (in the event of having a kenwood radio and if so...some kenwood radio's have a small separate remote wire coming directly off the rear of the headunit without the loom plugged in.
If not...many units will come with looms like this:
http://www.justkenwood.co.uk/images/iso_loom.jpg where u notice that there are spare bare end wires which are the 2 blue cables..one usually striked with a white stripe being the remote output...and the other all blue cable being the electic antenna for those cars with electric aerials. Now usually you can use either as a remote as both send power signal down those wires when the head unit is on...but i'v come across some where if you wire it to the electric antenna, you will only have ur bass on when the actual source on the radio is switched to "radio" as of supposed to CD or Aux (if applicable).
and then turns off again when u activate sourse to CD or Aux!?
So in this case..wire your remote cable to the blue and white striked cable being the allocated stereo remote output!
Hope this is more specific. (i'v used kenwood as an example but you may have some other brand where the same situation will apply)
