2019 Toyota Camry

On both frequencies do a -10db test tone. Only -5db when you listen to bass boosted, remastered and decaf music. -

What kind of music do you listen to? Do you ever listen to bass boosted music or decaf? -

If the loc checks out the if you tune the amps gain with the head unit at full volume then there won’t be any distortion throughout the volume levels. No distortion at 49. -

But an loc shouldn’t send a distorted signal. -

Then you have to turn the gain on the aftermarket amp all the way down and then turn the head unit all the way up and tune the amps gain with the dd-1 and the probes. -

Test the rca’s coming out of the loc that goes to the amp and check distortion that way. -

Now that you know that the head unit doesn’t have a clipping point now you have to turn the gain on the aftermarket amp all the way down and then turn the head unit all the way up and tune the amps gain with the dd-1 and the probes. -

Then that means that head unit doesn’t distort at all. -

I’m telling you dude, as long as them EQs are flat (at “0”) then most likely that head unit doesn’t clip at all, even at full volume. It wouldn’t make sense for a car manufacturer to put in a factory sound quality jbl car audio system and tune the amp they included with it to a distorted signal coming from the head unit. -

Use the dd-1 to check the input going into the factory amplifier that comes from the factory head unit. That’ll tell you the head units clipping point. And make sure the EQs are flat or at zero or whatever. You will need a factory wiring diagram to do so. But I don’t understand why a company would tune a factory amplifier on a distorted signal coming from the head unit. But you never know. But even if you find a clipping point on that factory head unit, how are you gonna incorporate it to the aftermarket amp since that factory amp is in middle of that circuit? Makes no sense. -

He said he checked the rca’s for distortion, not the speaker outputs. His amp showed distortion sooner at 49 because he has the gain turned up too much. If he turns the gain back then he won’t see distortion at full volume. He should be tuning that amp at full volume since there isn’t any distortion. But he has to check the head unit output first. The only way to test the head unit it’s self is to test the input to the factory amp coming from the factory head unit with the leads of the dd-1. Because him testing after the factory amp like he has been doing is only telling him that that factory amp isn’t distorting. It isn’t tell him shit about that head unit. He has to test the inputs going into the factory amp. He would have to use a factory wiring diagram. But I’m almost positive that a newer factory head unit isn’t putting out any distortion whatsoever at full volume of the EQs are flat. But you never know until you check. -

You will have to it through the speaker inputs before the loc with the leads to find that factory head unit’s clipping point. Disconnect that speaker and use them wires (that come from that head unit) to find the clipping point. Use a 9v battery to find out which wire is positive and which is negative to make sure the phase is correct. -

To check the if the amp is sending distortion to the speakers and/or subwoofers you have to plug the probes into the speaker inputs on the amp. The factory head unit isn’t the device sending off the rca signal so that head unit doesn’t matter. The loc that is sending the rca signal is what matters when checking if that device is sending distortion to the amp. You plug on of the rca plug that goes into that amp into the dd1 plug that the probes plug into and test the loc like that. -
After factoring in impedance rise and voltage drop, a dc audio 5.0k would do the trick. A 3.5 isn’t enough, no way.

Titan8 pwr-s5
1point21gigawatts replied to 08tahoe's topic in XS Power Batteries / Chargers! (and other stuff too)
Email XS directly or any of their authorized dealers and inquire. Email down4sound and XS and see who answers first and what each of them have to say about the matter. -
what numbers to expect from one 12w7??
1point21gigawatts replied to turnin26s's topic in SPL - SOUND PRESSURE LEVEL
Lol that’s a lie. There’s no way a 5000 watt planet audio amp would do a 153 on a 12” w7. Get the fugh out of here with them lies. Lies will get you ban. That’s stated in the smd forum rules. -
It probably sounds like shit because the amp isn’t tuned correctly and/or maybe that loc isn’t sending a strong enough signal and/or maybe that enclosure isn’t placed correctly or the correct size or specs that that subwoofer wants. Probably a bad enclosure build that doesn’t have enough port area or maybe too small or too big or maybe the pole vent is getting smothered. Don’t be mad at sundown. It isn’t their fault. You should diagnose things. And if you can’t, just ask us. State your problem and tell us what you are working with and we can help. Post some pictures too.

Would it be "as loud"?
1point21gigawatts replied to raymo2u's topic in SKAR AUDIO - (READ ONLY ARCHIVE)
Parking lots and foreign places and even your driveway when people that just drive by from visiting somebody in your neighborhood and see the sticker or traveling junkies that drive from neighborhood to neighborhood looking for a come up. It’s not smart. It’s some noob stuff dude. Only people that put car audio decals all over their vehicles are people that compete and advertise and most get paid for it or get discounts or free products for doing so and they have their comp vehicles locked up in a garage. I wouldn’t wish theft upon anybody. That’s why I’m trying to help you. You are one of us and we have to look out for each other. And I’m advising you not to label your vehicle. I have plenty of decals that would look cool on my glass. I even have really big ones. But I don’t use them on my vehicles. -

Take that decal off your window dude. That sticker tell junkie who car hop that you have a system. Move in silence and bump in moderation. You don’t want everybody knowing you have a system. Haters or junkies might try something. -

1point21gigawatts replied to raymo2u's topic in SKAR AUDIO - (READ ONLY ARCHIVE)
There would be no increase in swapping subwoofers. That amp isn’t on the verge of overpowering them EVLs. You are good. I’m gonna design some enclosures tonight. That’s the only thing you need. -
Yes, I noticed that and I am not speaking to the OP which doesn’t need help and probably hasn’t been on the forum in about a decade. I was just commenting to the guy who posted on this thread earlier today that was bad mouthing xs batteries and saying that the salesman saying xs batteries are superior to kinetic is just a snake oil salesman. I thought I’d prove that dude wrong. I don’t like people like that. He who answers a matter before he hears it, It is folly and shame to him. Folly means foolish. Meaning whoever spouts off at the mouth before knowing facts is a fool that’s looked down upon.

Sundown U10 tuning?
1point21gigawatts replied to Audiohz's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
Yes. If I were doing a build for that subwoofer I would tune it around 33hz. So 32hz is good. No worries.
