    Nice video. From a pro audio perspective you are giving some good info. Measurements is a great place to start. As we say in the pro audio world always use your ears. One of the biggest issues with time alignment errors is the cancellation of fundamental frequencies (the frequencies where the guts of most music and speech live). Usually around the 200-300hz range. A good way to set that is to play a 250hz tone and sweep the timing of one other speaker other than the one closest to yourself until it sounds like it’s directly in front of you. I measure the front left speaker and then start the delay of the front right speaker just past the distance of the front right. It’ll move from side to side as you sweep. Then once the front two are sounding centered I’ll use fade and balance to do the front left and rear left. The goal for this is to try and get the tone as loud as possible just by adjusting the delay of the left rear speaker. Then I fade all the way to the back left and right speakers and adjust the right rear delay until it sounds centered at my head. When that’s done I fade to center and adjust individual levels as needed.

    I got a new car and started upgrading the sound system in it. Man, I wish I started watching this channel sooner, it's one of the best sources for car audio info I have found. I haven't done any of the installs myself, but I always like to know what is going on during the installs in my car. Luckily, my installer is really into what he does and he explained everything in great detail, and I gotta say, he echoes everything I've learned from this channel. Mark, thanks for the awesome videos, it's always great to learn stuff from people who are knowledgeable and have passion for whatever it is they're talking. Keep it up sir!!!

    Was an installer for nearly 20 yrs. before switching to IT. That was an excellent explanation of path length differences and their effect on sound. Another area that always interested me relating to this is edge diffraction (and surface absorption) and their effects on sound quality. I judged a few IASCA shows back in the day and this was a pretty hot topic back then. Your thoughts?

    Mark you’re so awesome, I’ve been watching your videos since the pandemic and I had a little bit of previous audio knowledge from my stepdad helping me install my first system in high school, but what I’ve learned from your channel has immensely grown my knowledge to the point where it’s even impressed my stepdad who is an audiophile with what I’ve learned from your channel, I know this is an old video and I hope you see this, and I just wanted to thank you.

    From South Africa. Nice and informative video. Bought another car about 7 months ago and I'm looking at adding a DSP with the components, amp and sub from the my previous car while not replacing the HU. I've never had a DSP before nor have I ever known about time alignment, so your videos really help me understand better what I have been missing in my previous and current setup to get quality sound from my car. Thanks.

    Never knew so much abt car audio until watching your tube I resently took my music out of my car all because it wasn't sounding good and I have the Orion xtr 1600 watt amp and a 12"orion dual coil 2400 watt @2ohm a clarion pre amp expensive wires bayma 6.5 mid speaker 300 watts but now I know we're I went wrong thanks bro all the way from trinidad in the Caribbean car music here is a big business so trust me we have heavy sound system but few people know to create clarity music with even bass and mids which I just learnt about from you again thanks.

      CarAudioFabrication, I have some kappa perfects, but will be installing a wall with two btl 18s. I think I will need to add some mid bass as well. So can I use my kappa? And if I got an 8" mid driver will the easiest way be to just get a two channel to match those? Or get a three way crossover with a properly sized amp. And does that mean I will have to run active and have a hard time tuning, or should I get a dsp or an equivalent? Thank you very much

  • @Nildefects
    @Nildefects 8 місяців тому

    Great video as always from CAF. If you’re trying to time align 3 way passive speaker system, is best to take initial measurement from the Mid-range speaker? I’m using a Hertz DSP mini mk2. Obviously I can’t time align each individual driver as have passive crossovers.

Should I use those locations (with minimal modifications) or should I fabricate them into the A pillars so that they face towards center, instead of up at the windshield, which is the stock position?

    The first time I’ve ever heard this and why I never went to prime alignment but I’m old school from the early 90s. I don’t know how I knew that was back then but I know some people had it. I didn’t want my car throat it’s not horrible when I have a passenger. If I was to set the controls for my personal listening pleasure it be double as bad for them. Not only would it be further way it would sound even far because of the processor alignment.
    Am I correct thinking that. Or am I wrong? Like that you have shown that now we have a way to select center alignment or driver seat! I love it!!

  • @TheTherealdarkhorse
    @TheTherealdarkhorse 8 років тому +1

    Would it be unreasonable to do drivers side kick and perhaps apillar on passenger if it makes distance equal? May not be cosmetically pleasing but what if you are all about SQ. I have seen this back when DSP and time alignment wasn't an option. Have not tried it myself but back in the day in one case for sure it seemed to work for his case. Any thoughts or is that just crazy. I think I was seventeen when I heard it so I wasn't exactly a pro SQ guy. Just sounded pretty good at the time. Not really a necessary thing now but I do like my analog over digital. McIntosh digital to analog to be specific. God i wish they still made car Audio. lol.

    To me it seems old cars pre 70's and 80's need them in the kicks more and newer cars are better with the A pillars.
    A pillars are much closer in older design cars to the seating position... but there's less crap in the way like moulded door trims and steering column plastics

    @anthonyguy1347 8 років тому

    In my years of mobile electronics installation, many door, dash & kick panel locations are not as uneven as one would expect, but most of the times the speakers are mounted flat, so there is less of a directed sound. Making blocks that are cut at angles will often allow the speakers to be mounted in the same place, but will allow you to "aim" them better.

I had lots of SPL systems when I was younger but want a really clean, accurate sound for my new ride. I tinkered with an aperiodic sub enclosure when I was active in car audio and want to explore that route for this system. Do you have any experience with aperiodic enclosures or have any resources to share?

In my car(1990 audi 200) the ECU is in the passenger footwell righton the kick panel.Would the ECU be influenced by a speaker magnet(mid bass) if I would construct a speaker pod over it?Thanks from NJ.

    I'm from Texas and drive a 99 Mustang gt Coupe. I was wondering if I could use the rear side panels out of a converable for my 5X7 location instead of the rear deck lid? By using the panels it would bring the speaker closers to me and still keep a factory look by using the convertible side panels.

    Thank you for the information. I am looking at running the HSK 163 Hertz Audio 3 ways, so this info should help. I have the the HSK165XL Hertz and they sound great, these are my budget or I would the Mille's. Anyways, what would you recommend for a good DSP? Years ago I was using Audio Control, yet I see you were using an Audison, I believe. I am looking for SQ from my mids and SPL from my subs when I want them to be loud and I believe that with today's technology that can work.
    Again thank you Mark and take care, Craig.

    I have an 05 ford focus daily driver came with a decent enough sony xplod head unit but speakers are crap and the rear package tray has child restraint mounts so i cant put two rear speakers there I'm wondering about creating what I've heard referred to as front theater sound where the speakers are in front of the driver and not being concerned with rear speakers any thoughts
