The SQ Car Audio Thread V2

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.

Pick from one combo. The tune files are published for both, for the Cruze with the stock head unit.

Either the Silver Flute/Vifa combo or for a little bit more, the Dayton/Seas combo. Both will destroy anything with a car audio label at 3x their price.

XR,

I just finished reading the entire 43 pages (and am in the process of re-reading them) and have a simple question. When you say "stock head unit" are you referring to any Cruze stock HU or the one in your car?

I have an LT without the display/Nav stuff but was considering looking for a junk-yard find to upgrade as I need at least a display for my front and rear cameras and navigation would be nice.

I guess I have one more question. Do you (or anyone else who wishes to chime in) have a recommendation for an upgraded HU that will fit in with the rest of your suggestions throughout this thread?

Thanks for makin' my head spin:dizzy:

Robert

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

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.

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.

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!
Welcome Aboard!(y)

Don't forget to introduce yourself and your Cruze here.
