John Calvin puts forward a very simple reason why love is the greatest gift: “Because faith and hope are our own: love is diffused among others.” In other words, faith and hope benefit the possessor, but love always benefits another. In John 13:34–35 Jesus says, “A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.” Love always requires an “other” as an object; love cannot remain within itself, and that is part of what makes love the greatest gift.

    Car Audio [show your system]

    Hello! As promised, I am returning to show the next phase of the install in my Ford Focus: reducing road noise. My dad (aka "Pit Chief") is in this set of pictures. I could not have done it without his help. Btw, he was over 78 years old when that pic was taken in September 2016. We were at it all day! The car, as most smallish cars do, suffers from road noise. The extra noise gets mixed in with the music, and that is a real downer. But, you can't keep adding amplifiers and speakers just to overcome road noise. So, what to do? And why? And why choose what I used? Well, to reduce road noise, you need to dampen vibration directly and/or put a barrier between the vibrating surfaces and the cabin, a barrier that traps and dissipates sonic energy. Sound dampening material to the rescue! Now, sound dampening materials can be expensive, but there are less expensive alternatives. The sound dampening material I used is from Frost King. It conveniently has a very pliable foil backing to mold/hold shape around uneven surfaces. Its closed-cell foam is rubbery, thin but weighty, and has adhesive on the side opposite the foil. It is normally used to wrap vent ducts in homes and other buildings to reduce vibration, control air leaks and moisture, and to stabilize temps in the ducts. Let me tell ya, that stuff works great in cars, but you need cover a great deal of surface area. A little here and there will not have much effect, unless the car is already quiet and you're chasing isolated buzzes or rattles. You see, it is not heavy enough to stop vibration directly, as do some asphalt-based dampeners. Yet, it is very effective at trapping and dissipating the sound waves that would normally radiate off those troublesome surfaces. Finally, at less than $20 per 15 sq ft roll, it was a very affordable and effective solution for the problem of road noise. Think of it as making your other investments pull their own weight. I mean, you can't blame the rest of your system if it can't compete with road noise? Oh, and getting quiet tires helps. Mine are Pirellis, rated for 70,000 miles, and have one of the quietest ratings on the road.

    Today, I am moving on to the music source and delivery: the head unit, console, media inputs, and signal connectors. While this is the brains of the system, it actually is not the first thing I chose. I start with deciding the sound I want, and then I logically "back-fill" the design until I arrive at the head unit that will provide the signal I need. The head unit is a high-end, modest-cost head unit from Pioneer, the DEH-80PRS. It has features I am very much interested in from a sound quality stance. For instance, three individual Burr-Brown 24-bit D/A Converters, 5-volt preamp out x 6 channels, a microphone for auto calibration of the equalization curve, auto-setting of all levels and crossover frequencies/slopes on all channels and phase of the subwoofer, and auto-configuring time alignment for listener position. I was very surprised by the auto-eq (which essentially creates a new "flat"). Truth be told, I could never have gotten it to sound that good messing with all the settings myself. I did alter some levels and moved the fader toward the front a tad, while setting the rear speakers to the same level as the front. Also, I chose the "FRONT" imaging configuration that pinned the center image under and a bit forward of the rear view mirror. The console is from Metra, and its build quality is fantastic. Nobody ever thinks it isn't stock. The opening for the stock clock is where I decided to put my media inputs, two Neutrik USB ports that connect to the back of the head unit. To the left of the USB ports is the volume control for the subwoofer amp and its power and clipping indicators. The subwoofer level is all I ever need to adjust in the car... the main sound was a true "set and forget"! The console is not connected to the car's electronics, except for the hazard lights button and the auto-lock/unlock control for the doors. I encountered a problem with the depth of the head unit and needed to use right angle connectors. But, it wasn't until I got the Street Wires right angle adapters (the silver stubbies) that I was able to properly nest those outputs under the Parts Express right angle adapters (the tall gold ones). Then another problem arose: I could not attach the 19-ft Monster Cable Interlink 250 cables (three sets!) to the right-angle adapters because the barrels of the Monsters were too fat!! So, after a bit of searchng, I discovered Schiit Audio had purpose-built Vampire Wire cables with barrels that were very slim. The only thing left was to add some Audioquest female/female couplers to join the Vampire Wire cables to the Monsters. Done, and done! Oh, and the head unit has a remote control. That has been a nice convenience that is also a safety enhancer. Next time, I will show what went into dampening road noise and just making the car quieter inside overall. Plus, there's another appearance of my pit chief!! 🙂

    William, the work you did on the Accord is really something! You are a natural, my friend! And 240 HP is quite hefty. I know what you mean about not messing with some sound systems... many of them these days sound pretty good right off the showroom floor! (Sorry your Hyundai got hammered like that... not a good feeling.)

    I don't think that I'll touch the stereo of my Honda Accord. About a year ago the Hyundai pictured in the OP was parked in front of my place when I heard a knock on the door come 7:00amish on Thanksgiving morning. Some drunk took out the car in front of the house: That was enough to total the car. So a couple of weeks later I purchased a 2018 Honda Accord. The reason I bring this up is because this is the first "Ricer" that I've tinkered with performance wise. Don't know, perhaps Honda's rather recent presence in F1 racing struck a little fanfare in me. Anyhoot, spent some time away from the computer this evening and finally got around to installing some of the things I had in the garage for it. Cold air intake and I reprogrammed the computer to run optimally only on premium gas. Did I mention I boosted the turbo another 6 psi [total 26psi]? The cold air intake and calibration should make around 240 hp from the 1.5 liter Honda. Though my background is more in American muscle I get a kick of hearing this Honda's Turbo's woooooossssshhhhhhh. Installed the new wheels this evening: Took a couple of tries to re-calibrate for the different size wheels but I think it's all good now. The wheels were a luxury but part of preparing for my first winter here in Idaho. I plan to purchase a set of studded snow tires for the stock rims as it has and was snowing this evening. Time to wash my hands! Loving little hobbies like this off the PC.

    My first car amp was a Carver M-2120 from the Navy Exchange catalog... loved that one! But, when I got the first Soundstream Reference 300 in the 90's, I finally understood what "composed but powerful" meant in an amp. Btw, these are the "resurrected" Reference series amps that came out sometime in the last 6-8 years. The big change was to surface mount technology on the circuit boards. They are built even better than the first edition of the Reference line. I snagged these Reference amps in 2014, along with my sub driver and my main speakers, way before I purchased anything else for the current system. They sat in my closet for a while but I am glad I got them before they could not be found anymore. I have pics of their guts I will eventually post. 🙂 I always wanted a Zapco! Now I know why they were so sophisticated but enormously strong. Cool!! If I had unlimited funds, today's choices would be Zapco, Linear Power, or JLAudio. Glad you liked the work! (Btw, I think you will like what I did with the speakers in the doors... the overall approach was sound quality and stealth. Kind of an "unseen hero" motif!!)

    SoundStream!!! I remember them from back in the day of my Installation job. Big names back then besides SoundStream for amps were of course Rockford Fosgate and Zapco as well as Hifonics. I preferred Zapco whose products are made by a Nuclear Engineer. Working for an official installer of the company I received a very nice employee discount. Robert Zeff actually rebuilt my amp personally allowing it to go down to a 1/4 ohm load. The amp was rated at 150 watts x 2 into 4 ohms but nearly put out 1500 watts x 2 into a 1/4 ohm. A total cheater amp which allowed me to compete in 300 watt classes. Man you're bringing back memories! Love the install. Very professional! Any custom fiberglass door panels etc? I'm drooling while waiting for more pictures!

    Betcha the stereo had the "Reverb" option too. Was 8 track even out back then? Whistles, look at the caboose on that ride [nice fins].

    Becky, Don't act like you don't want to go for a ride in my car and jam on some Benny Goodman! 😉 Will, ** Spoiler Alert - Final Install Pics **: Correctomundo! The battery was a must, but I did not want, nor need, to change the alternator. So, I got my hands on two outstanding Street Wires 1 farad caps (with voltage displays). Incredibly, they have an excellent matching style/color scheme I wasn't counting on. There is a bit of unfinished steel and aluminum in the system... the caps fit right in! I positioned the caps as close to the amps as I could and they are fed by Street Wires 4 guage cable and lugs that you saw on the battery. One cap services my front and rear amps, and the other cap services the sub amp. Here are some pics of the power distribution with the caps in the design stage mock-up, and in the final install - complete with my pit chief (dad!). Sorry about the spoiler, but the pics of the final install display the caps since that is topical (i.e, addresses your question) and is the next in line to be installed after the battery. So, how do I know the caps work? First, my system uses Class A/B main amps and a Class G sub amp. (I did not want Class D amps though that topology would have been easier on my electrical system). The total rated output is over 1,200 watts, and I've pushed it hard enough to suspect I was knocking on the ceiling all the way around (my speakers are very high quality and can take more than my system can give them). Anyway, the proof of the caps' performance is in this: I can play music extremely loud across across the full audio spectrum when the engine is off, and then start the car and the music keeps right on going without a sputter!! Headlight pulse? Not even a hint. Of course, I had to bypass the ignition and supply power to the head unit directly from the battery to keep the source signal flowing for the test to have any meaning.... Lee 🙂

    Looking good [Gel cells and wiring]. One of the things most vehicles lack in way of powering a high end system is amperage. Do you or do you have any plans to upgrade alternator? Any large capacitors in the charging system? Can't wait to see other parts of your system!

    Here's where it started: the battery was my first upgrade (btw, the car is a 2012 Ford Focus SE). The O-nuts on the battery hold-down bar came from Hong Kong... they have tons of boats there, obviously, and so it was a good place to get similar items as the project progressed. Amazon to the rescue!

    Looking forward to your pics. After the military I began a career in the auto industry as a professional car and home audio installer. Never grew out of my love for high end audio. Be sure to post them pictures and in a build up stage. Just love seeing another's craftsmanship. God bless, William

    Oh, yeah... that'll do the trick! I will post some of my car stereo pics... I've been working on it for five years! (Note to potential wife: the project is almost done, I swear!)

    Hey, that is a sweet setup! Well done!!! 😎
  20. No longer have this car [Hyundai] nor this system but just thought to post a couple of pictures: Rockford Fosgate amp and line level converter. Only added some low end impact to stock system: 2 MTX 12" subs
  21. Just thought to share my system. Below includes Tekton's Ulfberhts L + C + R and 4-10 subwoofers. Amplification is from Emotiva 5 channel Gen 3. Speakers are currently driven to around 300watts rms. Unknown really the power output of the Emotiva with 5 channels driven as the amp is rated at around 530watts with only two channels driven. The subwoofer is an active design with 300watts rms. Just added two Klipsch height or Atmos speakers. This is currently a 58 speaker setup. Source wise are Sony Blue Ray 4k and Onkyo Preamp 5100 as well as Onkyo CD 5 disc changer. Visually a 65 inch Sony OLED. Another shot of my entertainment room: My wife after the photo was a little concerned that she wasn't the center of attention. Notice added are two Atmos height speakers uptop the Ulfberhts: Spaghetti! Bi-wire to L and R speakers: Atmos ~ overkill 10 guage wire.
