Guy used this as a starting point. Again, Guy deviated from the original plan with a different (corrected: Pioneer) Sub that has more range, but is a (?) 4 ohm so is not quite as powerful with the Kenwood amp. Plus, Guy saw how on the engine sub-forum I was susceptible to influence and concocted a plan to spend my money for me. You can blame Guy if you install the sub and think to yourself ‘hey, this sounds great, I should change the speakers!’
The link to the F150 forum has all the how to in it.
- pull the sub box - so easy, a trained monkey can do it.
- remove factory sub. you don’t even need a trained monkey, so easy, a US Fed gov worker could do this.
<beer. I like a pale, belgian farmhouse, or possibly a saison for this step>
- use heat gun or blow torch to melt and reshape factory sub box. Although fire is cool, it is not the objective of this exercise. If you’re a pyro, or suffer pyromaniacal tendencies, find another outlet. heat, reshape to fit the new sub, cool it and reassemble.
- wire in the amp. You can jump the inverter wire behind the seat on the other side. Grab a ground close to the amp, there are plenty available. secure amp, again, plenty of options, use your imagination. get speaker signal from factory sony amp connections.
<beer. I like a porter, Guinness, Dunkel or Belgian dark for this step>
smoke test. If you power everything up and the truck doesn’t catch fire, adjust the gain, and hz. to your taste.
Test with multiple songs, genres etc.
<bourbon. Bowman, Makers, Woodford, Wild Turkey, Four Roses - there are no bad choices with bourbon>
Enjoy more bass.
it’s that easy.
