I searched but couldn't find the answeres I need. I am installing a 2 chanel 250W kenwood amd and ARC Audio sub in fact enclosure. I am trying to hard-wire the amp to the factory harness. I tried to hook the factory head unit sub output wires to the hi level input on the amp and it didn't work. Is the sub output hi level or low level? Has anyone tried this and had problems making it work? I have a PAC SNI15 and I am going to try connecting to the low level inputs and hoping it will work. This has been frustrating to say the least. LOL

Also, if someone has done this before, how did you solve the auto power up on the amp? The factory "stand-by" wire doesn't put out 12 volts so it's not enough to turn the amp on (I had to plug into a 12 volt source to turn the amp on). Any and all help appreciated, thanks everyone.

EDIT: OK, I'm an idiot, I didn't even state the obviously needed info, this is an audiophile 9006 in a 2004 SVTF. LOL

Or you could tap your remote wire into the Green wire with a Yellow stripe at your ignition harness. It will then turn on and off with your car. Then you can keep your hard earned money in your pocket.

or if you really want to rig it funny, just go into your fuse box, find the fuse for the acessories, rap the wire around that, lol, I did that in my 91 escort, cause I didnt want to buy a cd player again.

a Volt-Ohm-Meter is useful for stuff like this (or use your tongue..[:D] )
I was able to use the blk/yellow?(pin 4) wire on the back of my stock blaupunkt HU.

the 9006 get's power thru 1 of those wires located on the harness...
[here I looked up some info on the FAQ]

The yellow (speakers) and black (power distribution) harnesses are the same as the 6006 ( http://www.focusfanatics.com/forum/showthread.php?s=&threadid=2140).

The other, smaller, black harness is here:

Oh, btw, the sub output from the head unit, is it hi level or low level?

OK, no matter how I hook up the sub output from the factory radio, I seem to get no signal. I tried using the high level input and the low level with an adjustable low level adapter and I get no sound out of the amp at all. Maybe I am doing something wrong, any ideas? This is very frustrating, I am so close to having it done.

The amp is new and works great, it's an Audiobahn A2002T. Everything is connected properly but there seems to be no signal coming through the factory radio sub output. Is it a floating ground system or something? This has gotten very frustrating. :-(

so you have the factory radio from a audiophile system and your using its sub out to power you raftermarket sub? did you have a factory sub with the car, and if not did you then buy a factory radio with sub outut?

you can also hook up a voltameter to see AC power if there is non then you have no output.

1) are you using the rear speakers?
if not, you could use a LOC or simply use the rear speaker wires connected to the high-level input of the amp

2) the stock sub wires from the HU are low-level pre-outs that connect to the stock amp

3) in the photo listed earlier, there are 2 White/Black wires. Make sure you have the right one (not the steering wheel contol wire). The right wire will be used for the RCA center pin +. The Brown/Yellow is the RCA outer ground -. The Wht/Red is the amp turn on. (Do you have the same harness as the one in the photo?)

It is the factory 9006 Audiophile system that came with my SVTF.

As far as that picture, I have not pulled my head unit out of the dash. I was simply trying to splice into the factory subwoofer amp harness. I have a wire diagram (pin-out) and I know I spliced into the correct wires. So, I need to splice a RCA male jack into the factory sub output wires and plug it directly into the low level input on the amp without a low lever converter?

BTW, yes, I am using the rear speakers, I upgraded all 4 of the cabin speakers because I will be adding an amp to those in the near future as well. Thanks for all the help, I sure hope I get it going soon. LOL

Ok, I assume you disconnected the stock amp.?.?

Then using the correct wires, you'll splice in an RCA (or pair of RCAs on the same wires) to be used with the new sub amp.

I haven't messed with the stock wiring with a stock sub/amp setup, but this is what makes sense. A HU sends out low-level pre-out voltage for the amp to amplify for the speaker.

Option #2:
Use a 4ch LOC for a 4ch speaker amp that has RCA pass-thru to then connect your sub amp to. This also requires your sub amp to have a remote level controller if you want to adjust the sub level any time.

Navone 4ch LOC

Option #3:
If the 4ch amp doesn't have RCA pass-thru, you could use an external crossover or dash-mounted crossover (or some EQs), that have 2ch in, and 4ch out with remote sub level control.

Option#4:
Get something like the Audio Control Three.1 in-dash 1/2 din EQ, Xover, Line-driver. It has speaker level inputs, so no LOC needed. You can set the Xover point between the speakers and sub. Master volume control, sub level control, etc. Both amps would connect to this. Provided you can find a place to mount it. [;)]

Yes, the stock amp is out and a new Audiobahn A2002T 2 channel amp is mounted where the stock amp used to be and it will be powering a Arc Audio 8D2. I also have an adjustable 2 channel LOC that I tried to tie in to the factory sub output and I got no sound, nothing, no matter how much I adjusted the POT's in the LOC or the gain in the amp.

A LOC converts a high-level signal to low-level signal. You connected it to a low-level signal.

Try the RCA thing next. (wiring an RCA to the wires)
