I don't have a pic of the RCA's connected to the back of the Alpine, but basically it's the connection of the small Metra harness (the Shaker 500/1000 connection) to the headunit.

I had read from other threads that if you have a Shaker 500, you only need to connect one of the 2 RCA's off the Metra harness, split it with a 'Y' adapter (single female - two male), then connect the 2 males of the 'Y' to the subwoofer preout of the headunit.

And if you have a Shaker 1000, plug the 2 RCA's off the Metra directly to the subwoofer preout of the headunit.

I ended up not using the 'Y' and going the Shaker 1000 route and everything works fine in my 500 system.

Oh man I installed this so long ago I wonder if I did this Y adapter thing you're talking about. It sounds good so I must've


But hey thanks A LOT for this write up. Helped me out a lot when I did my install. Especially the bypass connection and the regulator thing to eliminate the POP.

Dineau

Hey Bill, can you be a little more specific on connecting the resistor to eliminate the "Pop" ?

The resistor just have to be in serie between the amp wire and the radio signal ?

Thanks,

The harness I received from Crutchfield came with a built in 5V fixed voltage regulator!
Installed the Pioneer and no pop! It was on a Shaker 500 though.

Looks like they addressed this with the newer harness.

Going to install the same stereo into a Shaker 1000 system this week.
Ill let you know if it works on those as well.

Yes, but the old harness was free, and the new one isn't.

From Post 1...

Edit (3/8/10): Another option instead of the voltage regulator is getting a 1.5k resistor and solder it in-line between the remote turn-on wire of the headunit and the (2) blue/white wires of the Metra harness.

TacoBill,

Where do you have the Power and Ground connected for the rearview camera?



Thanks!

TacoBill

I believe I ran the power and ground to the center console switch and tapped into the 12V power plug supply/ground.

Did you need to use a heatsink for the 7805 regulator? How is the 1.5k ohm resistor holding up and does it consistently resolve the popping issue?

Dineau

No, with the 7805 yo don't need an heatsink. And so far it has been two years and the problem is completely gone...

metroplex

Thanks!
Did you install a bypass switch for the DVD/Nav? I know TacoBill installed the TR7, but others have noted that swapping some leads on the harness would do the same thing, and others recommended a $10 3-lead switch from eBay that seems to do the same thing (green parking brake wire, ground, and blue lead for the amp turn on).

I opted to order Fairchild LM7805 regulators from Digi Key because I don't quite trust Radio Shack's sources. A few people commented that they got varied output voltage values from the Radio Shack 7805.

Dineau

My head unit is a Pioneer X920BT, so I did the wire swap for the bypass.

As far as the 7805, don't worry.. Even if it's a little be less precise is not that critical, the goal is to get the voltage down from 12 volts to 5 volts, so even if it's a 1% tolerance (worst, worst case) it will be at 5.05 volts wich is good enough to eliminate the POP.

What do I do with the Blue Power ANT lead on the Metra harness?

I see there's a single Amp Turn On blue/white lead on the main Metra harness as well, does this get attached anywhere?

I think there is a typo in TacoBill's write up on the LM7805 regulator:
The input and output might be switched around. TacoBill wrote: I think the input should be coming from the Alpine harness (or aftermarket H/U harness) and the output should be leading to the smaller Metra harness.
