18 shaker pro amp & sub replacement..low level off the rear deck or stock amp wiring?

[Tyeayo1]

So...I spliced in an rca off the 2 wires that feed the level into the stock amp and WHAMMO, no clipping!

I have the 18 shaker pro, so I'm not sure if my wore colors match up to yours, but it will be 2 of the smaller gauge wires in the harness....I got a 7vdc reading on em both so that should set you in the right direction.

Swapped to front speaker tap and much improved!

I figured that would make a big difference.

Which front speaker wires (colors)?

Which front speaker wires (colors)?

Left +: White
Left -: White-Brown

Right +: White-Violet
Right -: White-Orange

I unbolted the amp and pulled it down, then stripped some tape off the wiring to have more access, then used t-taps into those wires and labeled everything with a sharpie.

It isn't fun.... but isn't too bad as long as you can deal with being upside down in the footwell for 30 minutes lol

You did this for a sub? Did you have the shaker pro?

No, premium 9 speaker

Ahh gotcha...that makes sense

I am having a hell of a time with this install.... I have a 12 inch Kenwood Excelon sub with a Kicker
47KEY500.1 amp. I have power, ground, remote all wired correctly. There is a 4 wire harness for input to the amp. I spliced speaker wires into that harness, and nothing....

1st, I tried grabbing a signal from the rear right speaker, and no sound at all. Then, I tried to grab the signal from the stock sub wiring harness in the trunk using the Violet/Green & White/Green wire. Still nothing...

At this point, I am questioning whether my amp, or sub is bad.

Using a LOC? Any voltage coming from the inputs?

I am not using a LOC, the amp is designed to take the signal directly from the speakers. There is voltage from the inputs. Also, I know there is some current going to the sub itself... I was able to shock myself when connecting the sub

I used the exact amp for my sub setup....I didn't pull a signal off the stock sub harness for that amp though, I used a LOC and grabbed it off the rear deck speakers. What I ended up doing, is returning the key rf amp, and just getting a cheaper mono amp...no need for all that other stuff when I'm only tuning in a single subwoofer was my reasoning.

But what you can try, and how I got it to work, was get a single rca and splice into each of the stock sub wires. They make a little harness that has an rca end, I'll include a screenshot. Than, once you've spliced into the stock sub wire, plug the rca end into a splitter, than the splitter into your amp..

What do you have the remote wired to? It could be possible you have a bad amp or sub.

The remote wire is connected to fuse #23 for the power windows. I used a fuse tap to connect it.

I am starting to think the sub is bad.... I disconnected the sub, and using my multimeter tested impedance. None registered. Tomorrow, I may remove the factory sub from the stock enclosure and run the speaker wires to it, just to make sure I can trigger sound on another speaker.
