Wow, you did this? Computer drawing and graphics. That's great. 36 hz. The box volume then matches the lower frequency hz, where the point of the graph increases, then cuts off or flattens. For this particular speaker. I see one other minor problem though. This is an old speaker. Newer cars will not make an older speaker sound good. But a older cars can definitely work on 36 hz, newer subwoofer. Car mechanic talk. It will have the power to power those subs. But yours, it may not produce low bass as intended. Frequency response may be good. But at 36 hz and at that specific box volume, output as planned desired, may not be possible. Reason speaker is already used and older. Not going to put in those performances on high output and lower bass reproduction. Just because it's already a used older speaker. May not work as planned. Hoffman's law in action. Thanks who ever gave me this. I think I was on some other name. I forgot. But three code names so far set up and changed. But google gave me this name. Nobody knows me. That is just my alias. Hopefully
Mitchell Fosgate III will last. Speakers. Definitely buying one. But planning it wisely. Or it will sound like some videos I checked out on youtube. Good for the toilet bowl. Too much static. Why do they listen to that kind of music? I don't know. Just fad or just want to be like me. Set one up too.
If you were to test these speakers, 4 or 2 ohms, may still be there and not burnt out. But at lower frequencies on a older speaker, it's not possible because the speaker is already warned out and already old. Whereas if it were new speaker, yes. Good deal. I'd go with the new speakers, only you'll need to pay for it. How much is one good subwoofer at 36 hz, 4 ohms and new? Any brand. Say JL Audio for example. Capable of producing the lower hz or tuning frequencies. $499 dollars for one. Money wise, you'd have to be certain you're a electronics geek or at most an electrical engineer. Otherwise if you're the average car audio guy around the corner, no way this will work out as planned. Not seeing this done.
Thank you! I'm reading the book now. Last point, there is a good mechanic book. Chilton's guide to Auto Accessories, copyright 1983. I've grown fond to Car mechanics. From the book.
Tip: "Each car has a 12 volt battery connected to components. It is connected 12 volts above the ground. By ground I mean chassis or metal part that completes the circuit loop. Not directly back to the source."
