Unfamiliar with line out converters...a couple questions?

Recommended Posts

Hello all,

 

Its been a really long time since I've put any kind of speaker into a car and never had to deal with a line out converter before.

 

I need to use one to keep the price down and because of the fact that I want to keep the stock headunit. So my questions:

 

1) If I run the rear speaker wire into the LOC, how do I get power back to the original factory speaker? (The amp I will be getting doesn't support anything but mono sub)

 

2) Can I run the speaker wire straight from the trunk instead of right behind the head unit? (Few wires to run through the car)

 

Thanks for the help, Im sure Ill have more questions later.

Will that overdraw the stock stereo by just splicing in a wire?

 

Also,

 

3) Can I use some "vampire" clips to splice them in?

 

Thanks Rao

Chris

 

I would be careful. If you wire the speaker in parallel with the LOC, you will be cutting the impedance in half (assuming LOC is 8 ohms). A lower impedance will pull more current from the amplifer and possibly cause damage.

 

I'm not sure what the impedance of a typical LOC is, but if it's low (under 1k) I would not recommend wiring in parallel.

The LOC just needs a signal and it is deisgned not to disrupt the original signal. I have had my sub wired this way in this car for 18 months and inothers for longer with no problems.

 

I have one more question for now that may have been covered before.

 

What do I splice my remote wire into with the stock stereo?

That is a good question. Normally you would use the power antenna wire, but that is turned off when you witch to a CD. I ended up tapping into the key on radio power wire. The diagrams have been posted I think and I don't recall the exact wire.

 

I found some info in the FAQ on the top of the screen about the pinouts for the Subaru stereo. Is the +12 volt ACCESORY the right one to plug into? (showing a yellow/red combo for 05 Subaru's)

Look at Rob go....the audio Q&A guy! :icon_tong Good answers all around. :)

 

Chris - we are doing an install day next weekend if you want to come out, I'll be happy to give you a hand (presuming you are not working that is).

Check out the PAC (http://www.pac-audio.com/default.asp) "trunk LOC." This will make your install much easier - it's signal-sensing, meaning it will turn on the amp when it hears a signal thru the speakers. You won't even have to take the CD player out of the dash.

 

They make respectable stuff and it's cheap on Ebay.

 

Great. I was thinking that for someone so inclined, making something like that would be easy but I just ordered a normal one from Crutchfield. Might have to return it if I can find one of these for a good price. Thank you.

 

Pat, I'm off that weekend and should be there.

I just ordered a Stinger adjustable LOC. It has a Left and Right input, both adjustable. So I can tap into the rear L and R speaker wires and be all set....

These are easily acessible from the trunk on the sedan?

Would they be the same color of wire as they are at the radio harness?

I am going to run a small wire along side of my power wire when I run that all the way back. I plan on using a 12v accessory source under the dash somewhere.... anyone have a schematic to any of the connectors near the driver's feet? I am still searching.... I know it has to be somewhere on here...

 

Thanks in advance.
