  1. I haven't read the other posts, but..

    If you are having phasing issues in your vehicle, remember these things...

    1.) Most of the time, the higher end of the audio spectrum can be heard best when notes generally above 2000 hz are positioned (tweeters) lower in the front door panels. From studies I have read about, you want to keep the tweeter pretty low, without having your legs and other obtrustions in the way of the sound waves. It can be difficult to place your components for the simple fact that a car is so irregularly shaped, and waves have lots of different surfaces to bounce off of. If you can fire the tweeter and midrange directly at your head, while keeping them fairly close to the ground, you will have a better chance of proper imaging. Keep in mind though, that the passenger side door panels will have an awkward angle doing this, as they are farther away from your head than the driver's side.

    2.) Also note that speakers in the back of the car will grossly take away from proper phasing. With them still in the back, you will be dealing with major cancellation on select frequencies because the waves from the back and the waves from the front will hit your ear at different points on the sine wave. Thus, cancellation. You can however incorporate lower end notes by placing midbass in the back panel, providing they are filtered to the 100-200 hz range, where the phase problems tend to not be so bad.

    3.) Besides the normal problems that people expericence with subwoofer drivers, this will probably be the least of your worries with phasing. Sure, drivers sound the best in one particular spot in the car, but the low end notes don't have as bad of a phasing issue as the higher ones.

    Hope this helps. Most of this info comes from Geolemon, if anyone remembers him.


  2. Hey everyone....I have been out of the scene for quite awhile now, and haven't been able to even look at car audio for around 3 months. Somehow, I snapped a cam boot in my engine, so I won't have a car for next season. Also, I'm moving out of the house and won't be able to get on the internet until some financial problems are solved. So, anyone may be able to get ahold of me through email... (jemorgan85@yahoo.com) if I ever have the chance to check it. Hopefully, I can get a new DSL modem for my birthday next Saturday, but even then I won't be able to be on for quite some time, so I hope every one has a good season in 05' and does well in the lanes.

  3. A friend and I ran a 15" SX in 5 cubes ported @ 36 hz and did a 143 on the new TL. I would actually recommend a bit smaller than that for SPL.....it was really in a box that it didn't like to SPL, but it did have awesome SQ.

    Well as most of you know, I recently finished the system I have been waiting for forever.... if not look in my sig.

    But anyway.... I was driving to work today, playing a song at low volume that doesn't have very much bass at all.... and suddenly I hear this horrible "pop" from my trunk. So, I turned the volume down all the way, and about that time, the most godawful sound came out of the subs.... extrememly loud and fart sounding. When I went to check it out... two of them were blown.

    Anyone who knows me knows that everything was installed correctly... subs wired correctly, gain set to match input voltage, low bass boost setting.... etc etc

    And somehow, these two subs blew. All four of them were on a Planet 1250D.... each getting roughly 200 watts.

    David, if you read this, please shed some light on it for me.... I had these playing in my room for awhile off of a 100 watt Cerwin Vega plate amp and never had any problems. I have only had problems in cars.... this woofer setup has been put in two different vehicles, and both times this popping sound has happened. The only thing Jmac and I could come up with is a woofer defect.

    Anyone have any ideas.....?

    Hope David's little sexy ass gets on here to shed some light on this.


  5. I'm so sorry to hear about the Stereo Integrity loss.... can't believe I didn't see this thread until today.

    Anyway, let's hope the insurance can do something about this so SI doesn't go to the wayside. We want to see more and more quality drivers to come out of you, Nick. I was personally waiting on D2 8's.....

    Good luck man,

  6. nicely written; easy to understand for beginners. I might be looking into one of thos pioneer or JVC HU's if you can get a discount :boink:

    Place the order for the one you want, then send scott@mycarjams.com an email saying that you heard about the site from me..... then supposedly he will give your card a 5 percent credit or something like that.
