The SQ Car Audio Thread V2

208532 500
Welcome to Version 2 of the SQ Car Audio thread!


The last thread got buried and full of information. It's a bit daunting to sort through, so I've created a new one to make it a whole lot easier and to consolidate some of this information. Given the sheer number of questions I get regarding this, I figured I'd create a thread to answer them off the bat.

My mission here is to make competition-level sound quality feasible and affordable so you don't spend the thousands of dollars going through parts only to come back to this point. Read this thread, and you can build on my experience.


Getting Started
To start, you'll want a good idea of basic audio principles so you know what I'm talking about throughout this thread. For that purpose, I've created four basic Audio 101 "lectures" on my website, which you can find in the link below. Start from the bottom. If you have questions, post them here. Don't even bother thinking about SQ car audio until you've read these articles.

Expectations
I'm sure some of you came here thinking "The sound system in my Cruze sucks, what can I do to make it better? I want some great sound!" I hear that a lot, and I have an inbox full of these types of questions. Before we proceed, there are things I expect of you. If you cannot meet these expectations, you shouldn't be here.


  1. Cost. As a starting point, you should expect to spend $1000 if you want a good set of front speakers with MDF baffles, a proper install with door and trunk treatment, good wiring, and a good SQ subwoofer in a custom box. If don't have at least $1000 or don't want to spend that much, come back when you have accepted the cost of this endeavor. This applies to total installs, not to just a single subwoofer. Some of you will probably say, "but I can do it for so much cheaper than that!" Really? With a passive crossover front component set, a single 8" subwoofer, custom box, two amplifiers, sound deadening, and an AA-GM44 harness, you're right around $930, and we haven't begun to talk about wiring. If you can build the box yourself, you can save some money. Otherwise, I build subwoofer boxes and MDF speaker baffles at what most consider to be a very good price.
  2. Time. If you want a system installed within a week because you just got your tax return, your bonus, or birthday money and can't contain yourself, don't waste my time. It will take you time to choose the parts that are right for you. It will take you time to learn why they were chosen, and why you shouldn't have bought the ones on the shelf at Best Buy. Since you will most likely be installing this yourself (let's be realistic, most shops do shoddy work by my standards), you will need time for that as well. We have some members on this board who can perform high quality installs should you really not want to pull your own trim panels.
  3. Effort. You need to learn at least the basics of audio. If you don't want to put any effort in, don't expect me to help you. I know this doesn't apply to most of you out there, but I'm saying it as a fair warning to anyone who thinks they can have their hand held throughout the entire process. I'm making tools available to you so that you can learn, have true appreciation for what's going on, and put together an excellent system.
  4. Patience. This ties in the last two points, but it deserves its own point. If you order a box and baffles from me, expect to wait a while as I've never yet had a day where I didn't have a box in progress. If it takes me 2 months to get everything done, chalk that up as part of the cost of getting a competition-ready custom made subwoofer box built for cheap. If you find yourself not understanding how something works or how to do something on your car, don't get frustrated. Ask questions, and wait for an answer. Keep in mind that we all have lives outside this forum.



In my next post, we'll move straight to system recommendations.

Pink noise
Description
Pink noise or ¹⁄f noise is a signal or process with a frequency spectrum such that the power spectral density is inversely proportional to the frequency of the signal. Pink noise is one of the most common signals in biological systems. In pink noise, each octave carries an equal amount of noise energy. Wikipedia


What is the difference between white noise and pink noise?
What's the difference between white and pink? They both cover all the frequencies that the human ear can hear, but the intensity of pink noise decreases as frequency increases. So whereas white noise can sound like static or a hiss, pink noise is smoother and more soothing across all frequencies.Mar 8, 2017

Velleman K4301: Pink Noise Generator Kit

I could not find a cheap spectrum analyzer. I bought my pink noise generator/spectrum analyzer in the late 80's from DAK industries for about $150 to help me set up my home stereo.

Looks like Madisound Speaker Store may have the Silver Flutes in stock. That's where I purchased mine. But the tweets are out of stock according to Madisound website as of today. Looks like parts xpress has the tweets in stock. Not sure how the tune file would work as your Cruze is a 2016 ( different body style ) i would think it would require some tweekng to the tune.

I never did the Big 3 upgrade but I can't see how that would help me. Most people claim it's for when you add a lot of power to your car.
The Cruze has a sketchy grounding system. When you add equipment that draws more power, it strains the already weak ground system. By adding a big three to the vehicle, you greatly enhance the grounding or return path as well as increase the flow capability to the starter.

Sorry, I could hear you breathing and moving, but nothing else.
funny....

Either way I solved this issue by getting rid of the joke of a DSP. If anyone visits this forum I'd suggest staying away from what these people are pedaling. The miniDSP is woefully underpowered and isn't even meant for car audio. That's coming directly from the company that produces it. Just stick with doing what everyone does and buy a reputable brand set of component speakers and save yourself the headaches! There's a reason why they're so popular and why these companies are so successful. They work. Sometimes it's better to stick with the crowd and not follow the 2 people saying that their way is better. I installed a totally different dsp and have no noise issue whatsoever now. I'd say that the average consumer of car audio shouldn't even bother with a dsp. As long as you can set your crossovers and gains don't bother with all of this extra **** these people say matters. The sound isn't improved as much as they try to make people believe it is when you eq or add delays. You'll get more bang for your buck steering clear of it.

Also they say you have to do all of this work with treating your doors and building adapters, Well actually the op guy is trying to pedal "his" adapters and sell you "his" stuff, in order for the junk to sound good they're selling. While I did all of that myself it's not once mentioned that instead of buying all of these separate pieces of equipment, you can actually buy a single unit that handles all of these things. You can buy a Helix M Four DSP which is an LOC, DSP, 4ch amplifier, and more! So while you'll save space and less wiring hassle you'll end up spending less money all together! Like what the hell are these people smoking? These people are just salesmen trying to scam poor souls just getting into car audio. Steer clear and follow the crowd on this one!

Not sure what your problem is but clearly you needed help and didn't get it. I've been too busy to put my time and energy into this project. However, my vehicle continues to run perfectly with the original miniDSP 2x4 that I installed back before this thread was written. That's what...9 years? Furthermore, they more recently sponsored me a c-DSP 6x8 that will be going in the 124 Spider, and they were quite aware of where I would be using it.

I don't sell the miniDSP. All of these years, I haven't made a single dime off of them, or any adapters or electronics. I sold speaker baffles for a few years and made very little profit and haven't sold a single pair in over 5 years now. I don't even charge for the tune. Going on about people getting scammed when hundreds have successfully implemented what you failed to is an admission of your ignorance and nothing else. The rest is just senseless rambling. Time alignment makes a massive difference, which is why ALL halfway decent DSPs have the capabilities and why all respectable tuners use it. 3rd order harmonic distortion measurements are used frequently when designing passive crossovers and allows one to lift the sound stage in a mobile environment as much as possible. That's absolute fact.

You need not search any further than the fact that we're nearing a decade since this thread was created, with just shy of 500 total posts, and you're the only one to come in here whining about your inability to achieve results. Of course it's everyone's problem but your own; that's how society operates so you may as well jump on the blame bandwagon too.

Perhaps you're right, that some people should just stick to components and passive crossovers.

Did the silverflute/vifa install with mini dsp a decade ago. I am a firm believer in sq sound. It was amazing. Now I use kicker key amps and they can be beat! And I still use silver flutes. Longest lasting speaker I have ever used!
