Installing a component system in a 2015

I recently installed a Polk Audio DB6501 6.5-Inch 2-Way Component System in my 2015 access cab following the advice of several here, Aw9d in particular (thanks for you help).

First I did the sound deadening using the RAAMaudio products, following their instructions.







I was also suggested I order a set of

$15 Metra 72-8104 Speaker Wire Adapters for Select Toyota Vehicles - 4 Total Adapters

Metra 72-8104 Speaker Connectors (which I did) to get the sound signal from the OEM woofer.



When disconnecting the OEM tweeter, I noticed there were 4 wires attached to the connector, but only 2 to the woofer.


Tweeter connector.

Aw9d said in past years, this wiring was reversed. So to use the Merta connectors, you have to bridge the tweeter connector.

My tweeter and wires look like this:



I don't like bridging, so I decided to use what was provided. Simply cut the 2 wires going to the tweeter (leaving enough to splice the connector back on in the rare case you want to reinstall them).




Plug the tweeter connector back into the harness, tape off the loose ends, and then use the woofer connector to supply signal to the crossover.




(Not permanent home for the crossover, it was placed in the door panel)

The deadening was definitely worth the effort. The new speakers sound really good. The entire project cost less than $300.

Thanks all for you input and help.

 

Do you still have the stock Entune head unit?

 

Getting to do this very thing myself...thanks for the post

 

Yes to the stock head unit.

Not Entune, it's the HD (which is useless where I live)

 

Did you put sound deadening throughout the entire cab? I've thought about doing this to mine but would like some real world results. Guess I could search but I'm being lazy

 

I just did my ENTIRE vehicle. My music stays in the truck and the road noise stays out. It's a worthy upgrade, but it's a LOT of work. You really have to WANT to do it lol.

 

Thanks

I don't mind doing the work or spending the money. I didn't buy my truck to sound like a Lexus but anything to quiet the sound is always nice. If you don't mind me asking, approx how much was the cost and how much would I need?

 

I decided that if I was going to go through the work, I was going to go bat shit crazy on it so I probably bought more than I needed(150sq ft+36sq ft of butyl)and layered it on as thick as possible. I spent around $350, which is a small price to pay for the level of satisfaction I get from it every time I drive it.

I came from a Lexus so I guess I kinda missed that quiet interior.

 

I heard a lot of people say the floor isn't worth doing and the headliner isn't worth it, but I'd always be wondering if it would be better. The headliner comes out pretty easy and the FatMat is super easy to apply to the long, flat roof so why the hell not? The floor is easy...once you remove the entire interior lol. The doors were probably the hardest since they're odd shaped and you want to do the inside as well.

I can't explain it, but the truck just feels nicer to be in.

 

I just did the 4 doors and rear wall. Before doing the deadening, I took a sound level reading at 55 mph : 77db. After applying the deadening ; 72db. The reduction is very noticeable. I bought a single kit from RAAMaudio. Delivered cost was $191. I spoke with Jason and he told me I would get the most benefit for effort by just doing the doors and back wall. As a previous poster stated, "the truck just feels nicer", especially when closing the doors.
