Re: [Chevelle-List] Stereo question.
Herbert, I don't think that it is your alternator, but your fans that are causing the problem. When electric fans start, they create a very large voltage spike, that can send feedback through your system. Using a high power amplifier and subwoofer can cause a pop or other noise. The solution is to isolate the fans from the rest of the electrical system with blocking diodes.

Bob, Steve, Brian, Thanks for the input. There's a Radio Shack close by work. I'll swing by there tomorrow and see if they have anything the will do the job. Also, the guy from the stereo shop called and his expert suggested I put a cap on the alternator (where the fans get power) that will shunt the excess power to ground. I doubt this stuff will be expensive so I can try both ideas. cYa- Herb - Original Message - From: Brian Zack To: '[EMAIL PROTECTED]' Sent: Monday, October 07, 2002 7:18 AM Subject: RE: [Chevelle-List] Stereo question.

Re: [Chevelle-List] Stereo question.
Hey Herb, I don't think a cap will prohibit this "thump" sound from happening. My understanding of a cap is that it "stores" power so that when youhit a deep bass note, it'll hit with full force or power. You're obviously getting enough power to make this "thump" sound so you shouldn'tneed more powerfrom a reserve storage of power. If anything that'll make the "thump" sound stronger. The cap is usually for a problem likeyour when your headlights dim at night when deep bass notes are played. The normal power from the battery runs the headlights (and everything else) at a consistent power level and then the deep bass note uses the normal power plus whatever reserve power is stored in the cap.

RE: [Chevelle-List] Stereo question.
Title: Message The Capacitor does store energy in the form of voltage potential on the plate. It's the effect of the voltage felt on one plate inside that causes the other plate to eventually feel the potential. The way a capacitor filters is by passing the potential felt on one plate through to the other plate without actually flowing direct current. So the energy felt on one side is kind of magneticallybled offto the other plate which is going to be electrically at ground. This means that any spikes in voltage at the one plate will be stored in the plate on the positive side, then bled off magnetically to the plate that goes to ground. AC passes through a capacitor in this way and since there is no direct connection between the plates, DC (Direct current) can't pass through ..or else you'd have a short to ground. So the AC spikes are passed to ground through the circuit the capacitor provides for them. This filter capacitor is going to be placed at the power supply side of the electronics where it can filter the DC for any spikes before it gets into the electronics,which could effect many things. It should have no effect on internal electronics by itself. And, if the power were taken only from the battery then there would be no need for filters. A battery provides extremely clean DC itself,so if the sound system were tobe turned on while theengine was not running it should be just fine assuming the problem is in the power being supplied and not the relays chattering. It might be a great test to try this Herb! Run the stereo while the car is off until the fans kick in. It should tell you if it's the power not being clean enough or if it's the relays chattering. However,I can assure you the battery would quickly go dead if the lights and stereo and other things were turned on while the car engine was not running. The alternator provides the power to keep electrical componentssupplied when the car is running. When the regulator senses that the alternator needs to start putting out more due to an increase in demand,the regulatorcan possibly cause a spikeand the alternator sends a power surgedown the line to keep up with demand. This power surge may be more than the sensitive electronics can handle without passing it on to other circuits. Especially since you are amplifying things tremendously with that amp. By the way, it gets rather involved, but if you get too large of a value of capacitor, which is rated in value in microfarads in most electronics,then the spike may nothave time to bleed off if it's a fast spike. It will passwhatever the capacitordoesn't have time to pass on to the electronics.You want a fairly fast reaction between the plates to handle fast spikes, this means a lower value would be best for extremely fast spikes. But since you don't know how fast your spike is coming without having equipment to measure it when it happens, it's best to try a moderate value to see if it helps at all. Bigger is not always better in everything. If you were to create that Pi filter you might try a smaller value cap onpower supplyside of the choke coil to pass the fast spikes to ground and a larger size cap on the electronics side to finish filtering the DC to a smoother level. Capacitors are also rated in their ability to handlevoltage. While 12 volts is not enough tobe any trouble for most capacitors, the spike could possibly be up to several hundred volts for a veryshort time period. While the capacitor is a voltage device, a choke is a current device. Electronically it is just a piece of wire made into a coil, but the characteristics of how many turns, the diameter of the wire etc. gets pretty hairy when figuring out the value in Henry's. Soa choke passes DC current through it just fine ..no problem but whenan AC component floats on the DC line, or a sudden surge in DC happens, the magnetic properties that a coil has opposes a sudden change in current. That's why a Pi filter is so good, it gives any spikes or AC riding on a DC circuit a "triple whammy". Considering that your alternator is an AC power supply, and has to be rectified and filtered, and it may not be enough at times to handle huge surges in demand. your sensitive electronics just may need a little extra help in filtering out stuff that wasn't intended for it to handle. I have to suspect that the engineers have the recommended sizes given to the stereo stores to handle problems like this and I'd go with what they recommend. Not sure I'd trust the decisions to the guy that installs the stereo though unless he's very experienced and has electronics training in college.

RE: [Chevelle-List] Stereo question.
Title: Message Herb, I am not an electrical engineer. I was only a technician. But I had to know most of the theory. Still it's been years so I could be wrong on this and somebody please correct me if I am wrong. First, since the alternator feeds back to the battery to keep it charged, they are electrically the same point no matter where you take your power from .unless you haveresistance losses from smaller diameter wireor long distance wires or other things in the circuit (such as terminals with corroded connections) that don't allow the full potential to be felt at that point (- resistance).The alternator is the one feeding the electricity to circuits needing it or your battery would go dead. You always want to make sure that your wires can handle the current being drawn though. A 6 gauge wire should do the job. It could very well be that the relays are chattering when switching. If that's the case, might have to research a fix. It could also be that the alternator switching on is causing a spike as you suspect that will effect some sensitive electronics. You are on the right track in thinking capacitor. A capacitor is a voltage device it filters voltage fluctuations, and it won't pass DC current, so it has to be from the positive line to the ground.A choke (coil)smoothes out fluctuations in current. Afairly good filter design is a choke and a capacitor working together.One of the more common designs for electrical filtering is a capacitor with a choke then another capacitor. That's called a Pi filter due to it looking like the Pi symbol.I haven't look at Radio Shack lately but they may have something like that already to install. I say go for the voltage/current filter first, then troubleshoot the relays. They may not be hefty enough to handle the load. They may need some filtering that the filter would solve.

Re: [Chevelle-List] Stereo question.
MessageSteve, You always want to make sure that your wires can handle the current being drawn though. A 6 gauge wire should do the job. Actually, the 4 channel amp has the 6 guage wires and the sub amp has 4 guage wires for both pos and neg. It could also be that the alternator switching on is causing a spike as you suspect that will effect some sensitive electronics. You are on the right track in thinking capacitor. A capacitor is a voltage device it filters voltage fluctuations, and it won't pass DC current, so it has to be from the positive line to the ground. When you say from the positive line to the ground where exactly should the cap be placed? The cap I was considering are those big ones you see in the high end sound systems. If I remember correctly these type are in line on the +12v supply wire. A choke (coil) smoothes out fluctuations in current. A fairly good filter design is a choke and a capacitor working together. One of the more common designs for electrical filtering is a capacitor with a choke then another capacitor. That's called a Pi filter due to it looking like the Pi symbol. I haven't look at Radio Shack lately but they may have something like that already to install. Would something like this from Radio Shack be suited for 800 watts? I say go for the voltage/current filter first, then troubleshoot the relays. They may not be hefty enough to handle the load. They may need some filtering that the filter would solve. The stereo shop placed an order for one of those big caps (none in stock for some reason), and they're going to ask some other experts about my situation.

John Nasta -Original Message- Hey Herb, When you did you wiring with MH, did youorder thefactory stereo and speaker harness or just skip that since you're not going to use a factory stereo? Also, what custom wiring did you have them do for you (HEI, internal regulator, etc.) I'm seriously thinking about redoing my wiring, but I'm not sure what to do about the wiring for my stereo and the wiring for my Vintage Air. I'm also wondering how much custom mods add up to. Thanks for any input from experience. Rodney. 71 Chevelle El Mirage, AZ
Re: [Chevelle-List] Stereo question
Title: Re: [Chevelle-List] Stereo question Rodney, I didn't get any speaker wires but the power wires for the radio are there. I'll be splicing into those. As for harness mods, MH only offers a couple things, such as HEI ($14 extra), internal regulator (another $14) and since I used a one wire alternator, I was told to just fold the extras back and cover them with tape. Since I redid my charging system a little, I completely removed the excess wires. I wouldn't worry about the stereo wires, there's plenty of places to tap in, and Vintage Air has it own harness with one power wire, a few ground wires, and one vacuum hose, pretty simple. cYa- Herb Lumpp1966 El Camino, LS6, 6 spd, Currie 9"ACES 3509, MCC 528http://users.adelphia.net/~hlump/ - Original Message - From: Rodney.
