Kicker Hideaway with LC2i w/ Stock Tacoma Strereo

Joseph from El Paso, TX on 5/22/2025

2014 Toyota Tacoma

Verified customer (What's this?)
Verified employee review (What's this?)

Initially had the wrong hook up and called Crutchfield. A few minutes later a tech walked me through a few steps and corrected which connection I needed to power up my Kicker Hideaway and within minutes the thing was booming. Zero issues since and works flawlessly with my LC2i LOC.

Pros: fairly easy to hook up. great instruction provided over the phone.

Cons: lots of options to connect, so you have to know the right ones which Crutchfield instructed properly once I called.

Verified employee review (What's this?)

Works as advertised. I was able to connect my powered 10"sub to my factory headunit. This kit completely eliminated the need for posi taps or any cutting and splicing. I wired this in the parking lot on my lunch break.

Pros: Quick install Wire color detail sheet

Cons: Not a big fan of the small connectors but this is minor it's a solid connection.

Mostly easy to use, no splicing needed

Katelyn from Bozeman, MT on 2/2/2025

2013 Toyota Highlander

Verified customer (What's this?)
Verified employee review (What's this?)

This harness was overall great I used it on my 2013 Toyota Highlander to not have to splice anything for hooking up a line output convertor. All the plugs fit like they should into my headunit my only issue was that the yellow power wire was keeping my loc and my radio and amp on after I turned off my car. But it ended up being a pretty easy fix. I just taped off the yellow wire and tapped into the fuse for my cig lighter for power, and now everything works and turns off as it should.

Pros: No splicing needed

Cons: Yellow power wire kept equipment on

I would pay more for these harnesses the wires come pre stripped quite literally plug and play just plug it in the head unit connect the wires to the anp/loc and done it comes with line in 12 and ground so you don't have to search for one and gives you the speaker inputs without having to tap into the speakers.

This harness worked great on my 2009 Toyota Sienna without factory JBL. I used the factory Toyota stereo and installed a kicker key 200.4 amp. I already had installed 4 JBL speakers bought from Crutchfeild. It sounds great now.

Pros: Very user friendly

Cons: None

PAC LPHTY01 LocPro Advanced T-Harness

Erick from Chino Hills, CA on 9/30/2024

2014 Toyota Sienna

Verified customer (What's this?)
Verified employee review (What's this?)

T harness for 2014 Toyota Sienna with factory 6.1 NAV screen is pretty easy to use once you figure out that you need to disconnect the male the female connectors from the main harness, before attaching the accessory connectors that will extend to/from the amp or LOC. Had to read and look at the figures multiple times before I finally figured it out. FYI. The High output level signal from the radio did not require me to use the remote wire to the amp. The Amp will turn on/off from the RCA signal. When I had the remote wire connected to the factory radio via the RED accessory wire on the (LPH-SPK(F)) harness, my factory radio and amp would not turn off at ALL. Took two days to figure it out when I called tech support and we disconnected the T harness and reconnected each one, one at a time.

Pros: no splicing!!! Easy to install once you know how to connect the accessory connectors

Cons: Instructions could be a little more clearer. In my case, does not warn about Hi level output can turn on amp without remote wire and should not be connected under that situation.

Great!

Jonathan from Rocky River, OH on 8/5/2024

Verified customer (What's this?)
Verified employee review (What's this?)

This harness worked for my 2019 Toyota 4Runner. Initially ordered the LPHTY02 variant but the connectors did not match even though the listing for the 02 specified 2019 and up. The included wiring guide was helpful because wiring identified and matched the OEM head unit main harness colors. Did solder on each channel connector @ the head unit. Liked that the remote wire was in this harness as well. Very straightforward and very nearly just plug and play.

Pros: Clear documentation; good quality harness

Cons: Not plug and play; but nearly so - some soldering required.

Have a Highlander and want to add an amp? You need this!

Mario from Plymouth, MA on 7/7/2024

2012 Toyota Highlander

Verified customer (What's this?)
Verified employee review (What's this?)

If you have a highlander and want to add an amp without messing with the factory stereo.this is the harness to get. It's super easy to install.just a few snaps, then you connect the clearly labeled outputs to the amp and then connect the amp to the clearly labeled inputs, power and you're in business. I used this to connect a kicker key to new dash and f/b door speakers and it's worth every penny! Excellent T-harness!

Pros: Easy to install, clear diagram of wires, labels are easy to follow. Really an excellent T-harness!

Cons:

Great harness to use with Kicker Key 200.4

Lawrence from Winston Salem , NC on 8/12/2022

2012 Toyota Tacoma

Verified customer (What's this?)
Verified employee review (What's this?)

I have used this to wire a Kicker Key 200.4 into my Toyota Tacoma 2nd Gen Factory Radio. You need to modify the harness to use with the Kicker Key but the instructions are easy to follow. It requires you to cut the wires going out to the Speakers so that the harness from the Kicker Key can be spliced into the harness. Great thing is the wire colors of the Key 200.4 match the wire colors of this harness.

Pros:

Cons:
