Stock Audio Specs

All,

I am planning a small system around the stock headunit and amp in my 2018 Tundra non JBL.

My plan is to either get some 2 inch widebands for the dash or tweeters and either a 6.5 or 8 inch midrange for the doors.

My question is what are the stock ohm ratings of the door and dash speakers and will the factory amp work with a 2 ohm load?

Also, does anyone know if an 8 inch midbass driver will fit in the door without modification?

 

No, 8 inch mids will NOT fit in the doors without modification. And why would you want to do that anyway, if you are keeping the OEM amp? It could never power them. Do yourself a favor and wait until you have enough $$ to get an aftermarket amp. Do not waist money on upgrading the dash speakers either. The dash speakers are total overkill. Most of us simply delete the dash speakers. Get some nice 6.5 components for the doors and a 5 channel amp. And later, upgrade the sub and box behind the back seat. While you are at it, get an aftermarket wiring harness to make the install much, MUCH easier.

 

I'll second no need for dash speakers. I have 2.75" Kenwoods there and Hertz K170's in the door and now use my

Kenwood DMX1037S to both attenuate both front channels plus it has the ability to specifically attenuate the tweeters because the Hertz K170's + Kenwoods are too loud and bright.

 

I have Rockford Fosgate speakers in my doors, and 2 subs under my back seat. I still have factory dash speakers...haven't swapped them out yet. I get alot of sound from my dash speakers, so I don't know why some delete them.

 

For me it's just too much sound - especially the highs. So I have to lower all the levels up front compared to the rear. The situation is "tunable" to sound good I just wonder if I never bought the dash speakers if I could run the front channels at full strength and would there be a difference?

 

Hey PWMDMD, do you have an installation thread for that

DMX1037S?? Any tips or feedback?

New HU is my next big thing.

 

The biggest driver for me to eliminate the dash speakers is the phase issues they create. Essentially, it sounds goofy all over the truck, though I'll give toyota credit in their processing/time alignment. I cannot stand how much comes from the dash, and almost assume they wanted the sound stage to feel like its in front of you, but it destroys the stereo imaging I personally prefer.

I went with Tech12's recommendations, and am going to swap everything but the head unit, this week while I'm off work. 6.5 components front and rear doors, dual 10s, 5 channel amp, and the DSR1 with his tune downloaded. Keeping the factory head unit, for now, and eliminating the dash speakers.

If you just want a basic upgrade, get a harness that will let you swap out the factory amp, and drop some solid component 6.5s in the door, and a single 10 or 12, and you'll be content.

 

Thank you all for the information. It is definitely food for thought. The first step however is getting the door deadened so they don't sound like rattling tin cans.

 

It is possible.

How do you adjust the dash speakers seperately from the front door components? I have a DMX907S and I can't figure out a way to do that. I see that you can set it up with tweeters in the one setting and then adjust them but I never noticed much of a difference. I just pulled the dash speakers.

 

I have to lower both front channels -5db + there is another setting just for tweeters and only on the front channels that I lower another -3db.

 

Okay yeah I have the same thing. I played with it a little bit after reading your post. I've adjusted voltage and all sorts of stuff. My tweeters start to distort at volume level 30 and the speakers aren't near loud enough. I think I have EQ'd them too much. Waiting until I get my subs installed to make any equipment changes when I can drop the bass on the speakers.

 

In audio settings, choose "Speaker/xover". Find the option "HPF" for your tweeters. Thats the filter that will determine where you will cut off how low the tweeter will play. Raise that number higher and that will help eliminate the lower frequencies that are causing distortion.

Also in the audio setting choose "Listening position and DTA". You will find the option to set the volume levels for each speaker.
For the eq, if you don't have a microphone with a calibration file you really are kinda just guessing cause it takes a little while of listening to the adjustments you make before your ears get used to the adjustments. Basically if you are used to listening to a basic boombox your ears will have become used to how they sound and that is what you will mental reference as what sound correct. Most ppl don't know what a properly tune setup sounds like and will even dislike a properly eq'ed sound system when the first hear one. It takes a few days before it starts to sound pleasing and eventually sound great.
Setting it to flat and focusing on the time alignment and speaker volume levels instead will get you to a much better sound quality level much faster and easier.
Eq'ing it is really the final little extra icing on the cake. If eq'ing it yourself isn't getting you the results you want its ok. You can absolutly save that for later after all the other things are setup. Thats just in my opinion of course.

And thats a really nice head unit too. The tuning options it has already incorporated into it is pretty extensive and amazing. Theres months of fiddling with setting to play with. Great choice.

 

I'm running components so there is a crossover that they are wired into. The head unit can't isolate the tweeters because it only sends one signal to the front door speakers and my crossover handles splitting the signal. I believe I only have the ability to set the HPF for the front channel which makes sense. This is where a DSP and the tweeters on their own channel would be awesome.

I do really like the head unit, it was a solid grab. I had no idea at all of the processing and customization it had. I have set the time phase adjustment and I'm still playing with it. I know I'll have to start all over with pretty much all of it when my subs get here and I get them thrown in. Right now I keep tweaking little settings trying to figure out what my ears like the best. Thanks for the heads up.
