Just awesome! I can't wait to see the finished product here. I too enjoy my SQ, and since I'm not a racer, I really get into the stereo logistics.
I too drove a minitruck in the 90's, it was my baby. 5 grand worth of stereo in it, and enough neon to light up Yankee stadium. I miss that truck, and have often toyed with the idea of getting another one, but the wife always brings me back to reality. lol Joe |

The "need"?!?! That's pretty funny coming from the guy who stuffed a 928 V8 into his car. (IMG:style_emoticons/default/smile.gif) -Steve |

QUOTE(Black22 @ Oct 28 2010, 07:13 PM)  Just my 2 cents, but I used to be heavy into car audio and was a Sound mixer in Hollywood for 15 years. I was always told that for every 1 subwoofer you put in a car you should have two of every other smaller speaker to have a balanced sound stage. Meaning if you want a 12" sub and 6" mids plus 1" tweeters you should install the 12" with 2 ea of the 6" and 2ea of the 1". That system would sound good if you deleted one of subs and used the 3rd amp for more mid and high range. IMO. It'll sound good the way the schematic shows, it's just overkill on the bass side unless your a mini truck from 1990. Also I didn't notice any specs on the amps. You don't need a huge amount of power to be loud and clean. I once had a system in my Mustang that used 3 amps that had combined total 135 watts that produced a measured 140dB at a contest. It's not how much you use but how and what you use. (IMG:style_emoticons/default/agree.gif) Very cool. BTW, the sub(s) needs to 180 degrees out of phase with the other speakers. |

Very cool, don't worry about the old farts who wonder why you want such a nice sound system, personally my car is so loud it is hard to hear most things, but I still went ahead and bought some Polk Audio 6.5 inch coaxial speakers for my new A and P pods and Kenwood CD player....got to have some tunes while driving to work and sitting in traffic. Your system looks very cool and well done! Cheers!!

(IMG:style_emoticons/default/shades.gif) (IMG:style_emoticons/default/shades.gif) (IMG:style_emoticons/default/shades.gif) This information is not exactly correct. bass phase polarity only needs to be 180 degrees out if your system design creates Negative Wave Propagation. NWP is caused when the audio sine wave from two opposing speakers meet at the lowest point of the wave. This causes a dip in sound pressure level. Frequency and physical distance also play a big part in NWP. Many newer electronic crossovers have a switch to place the output out of phase. You should always experiment with woofer phasing for best sound. Not simply place it out of phase. The same audio sine wave can also create Positive Wave Propagation. This is the opposite of NWP and usually occurs when door speakers face eachother. PWP effects Mid Bass frequencies most often in a vehicle. It can make the music sound muddy in the Mid Bass region. An easy fix for this is the fabricate a half round wedge to be placed under the speaker so the two don't face directly opposing. |

For those interested. Here is a woofer box Port Nomogram. This will help you figure the diameter and length of your tuned port. Use the largest practical diameter for best results. Small ports can make wind noise from air movement. PM me if you want a pdf.

QUOTE Use the largest practical diameter for best results. basic rule of thumb that I went by for building sub enclosures was to aim for having ports roughly 1/3 the diameter of the sub they were getting matched with. Wasn't always the case, but it made for a great starting point. Joe, great thread; I've been waiting for this one. The amps look great! |

Seriously Rick, you got no legs to stand on here! (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/biggrin.gif) In my limited knowledge of building stuff I see this as apples and oranges. I guess if I installed a 928 V8 in my stereo it would make as much sense as installing 250 lbs of electronics, duel batteries and three miles of wire in my sports car. Well I guess unless I had it parked in my livingroom. (IMG:style_emoticons/default/shades.gif) Anything that doesn't make it go faster or turn sharper should be left on the garage floor. But that's just me. I guess the stereo is cool if it was in a tow vehicle but like I said, I never understood the need to do that. (IMG:style_emoticons/default/confused24.gif) |

It's too bad cars this old didn't come with nice sound systems like today's cars. IMO, a system such as this, if done cleanly without damage to the car, is a work of art.

Haha, my buddy and I were reading your thread on the Phoenix forum the other day. He know alot more about older systems, tube amp type of stuff than I do, but he was very impressed.

I got my cables today (IMG:style_emoticons/default/piratenanner.gif)
 I will be finishing "The Big 3" 0guage wiring from multiple batteries to the distro block, then 4guage to the amps. I will be fusing every lead right at each battery. The ground wiring will also be 0guage from the battery to the chasis, to the alternator. I also bought extra wire to run 0guage positive and negative to the starter (IMG:style_emoticons/default/happy11.gif) There is a longer run of 4guage that I will pull to the front to feed the head unit and the DD5 wich will run to each component. This should cure any dimming at high volume (IMG:style_emoticons/default/first.gif) I will update with install pics I had no idea just how big these cables really were, everything looks smaller on the computer, but DAMN (IMG:style_emoticons/default/rolleyes.gif)  |
