2013 Jeep Jku Sahara install

Used this to hook amp and sub to my factory radio that uses Alpine sub for premium audio option. The install was very easy and everything worked with zero problems after.

Pros: Allows to keep factory radio and amp , also retains steering wheel controls

Cons: A little pricey but makes for an easy install with no problems after

This is a great manufacturer putting out great products. you can find their gear all over the place. online, in local stores. pretty much everywhere that is in the business of aftermarket car audio. Because PAC is such a great company their products often sell out. PAC will be, or, have already become, a household name in the industry (as of today 8/6/21 Google records 13,132 reviews for this averaging 4.8 stars). I purchased mine from Crutchfield because of price and availability (which correlates with excellent lead time- Crutchfield ships FAST for FREE) I also enjoy accumulating customer rewards points I earn with each Crutchfield purchase. FYI this product does not cancel the signal to the stock sub nor does it disable the stock sub. This wiring interface is an addition to the stock system which in turn allows you to add another sub&amp or (or more) to your stock system while keeping every other aspect of your stock audio system completely original. The level control knob will have no effect on stock levels being sent to stock speakers/sub. If you can't tell. I'm very happy with this product. If it is in stock pick yours up today!!! You won't be disappointed. Once you've experienced this versus any comparably priced alternatives PAC will be your go to choice!

Pros: Simple to use and relatively easy to install Small, easily fits in tight spaces Includes control level knob to adjust sub volume Includes Switch to Adjust RCA output voltage (5 volts or 4 volts) NO CUTTING needed!!!-plug and play harness!

Cons: Might not be in stock Doesn't include mounting tape/Velcro

Easy install and does the job

Easy installation and works perfectly. just plug into the factory harness and Boom, you have rca ouputs to run to your amplifier or amplified subwoofer. Perfect for adding that extra bass and control. The added bass level remote is perfect for tuning to different songs or lowering the bass when you have sensitive passengers or just want less/more for a particular track.

Pros:

Cons:

Must have harness for adding Sub

Verified employee review (What's this?)

Outstanding product offering the flexibility and ease of install. I now have sufficient bass in my Jeep that I never thought I could get with a stock radio.

Pros: Plug and play, super easy install, no wire cutting or altering original radio setup

Cons: None!
