I would think this is the right place to put this, seeing as how it involves my audio equipment. However, it is not for my mustang, its for my explorer.

Anyway,I installed an AlpineV-Poweramplifier (monoblock)to power mytwo JL Audio 12" W1's in my 93 ford explorer. I connected all of the wires and they appear to be correct. (power, ground, remote turn on...)

Before I connected the remote turn on wirefrom my deck to my amp, thedeck would play cd's and the radio perfectly. Now, It will play the cd or be tuned to a station but absolutely no sound will come from any speakers. The only thing that is audible is my subs. Whenever I turn the ignition on/off or I change from tuner to cd... allthe subwoofersdo is buzz for thatmoment. (kinda hard to explain) Everything worked when they were in my old car, and the Sony deck that is in the explorer worked just fine earlier today also. And yes the amphas power.

If anyone could help me out that would be great,
Thanks, Addison

 

mite sound stupid, but did you unplug the pigtail on the back of the headunit? or jar it possibly, to knock it loose?

 

...uh, pigtail??
i dont know what that is...

I did check everything on the back of the deck and they all seemed to be tight. (pre-amp outputs, harness, power...) Also, that sound I was trying to explain occurs whenever I try and changethe track ona cd... IDK

 

pigtail is the plug that plugs into the back of the headunit.. with all the wires.

the whole system doesn't make any noise? besides the subs buzzing? did you try un hooking the sub amp?(just the RCA and remote lead, to turn the amp off)

 

sounds like loose wires or a bad connection to me, too. ^^^ check those RCA's, and if that's not it check the h/u settings or something. I don't know if sony's have low pass filters or anything, but that might be some of it.

 

You probably have an amplified factory amp somewhere and you didn't connect it along with your alpines remote wire...

Well... Maybe not, but check, thats about all I have the time to think up and type right now.

 

I think it has a factory amp, (at least my dad thought it did)my brother-inlaw had set up the deck prior to me driving it and all ofthe speakers worked so I left it and just added the alpine and subs...

Could someone tell me how I should wiremy systemin...

Thanks, Addison

 

you had the head unit installed for a while before you installed the subs though didn't you? and it worked fine? or was it in a diff car before?

 

yea, basically when the stock radio went out, my parents took it to best buy and they said they needed a special adapter or something in order to make the aftermarket deck work... IDK, they said it had a high quality orbetter package (stock)ford speaker system in it or something. My brother in-law had recently installed the sony that is in there now and I have just tried installing the amp and subs... Yesthe sonyworked completely fine before I hooked up the amp/subs, and the amp/subs worked great in my old car...

So this is why I have come to MF to try and solve this problem I'm having... I'm clueless.

 

UPDATE: I connected both remote turn on wires to my amp (ant rem and amp rem) and had the volume all the way up on the deck and could hear the subwoofers but they were really quite... sooo idk, there was also a (what my buddy and I think) factory amp bypass connector, from install edge, part number IEC PSI2

any more help would be appreciated...
Thanks, Addison
