    1st topic

    I have nothing to show off ...
  5. Well, if he added it to the old database, he can still use HT Merge to put it back in the database ...
  6. Why don't you just use HT Merge to re-integrate the drivers ? That IS what it's there for
  7. How can I view .avi files using Windows Media Player ? I got some Family Guy episodes I want to watch, but all I get is sound ...

    Amperage Draw

    If you're playing nothing but sine waves, have all the options available for your car, and have them all operating at the same time, then you might be only limited to 32 amperes in your example. However, music is dynamic, most people don't have their A/C, heater, and lights on at the same time and most vehicles aren't fully loaded. Most headlights draw maybe 5 amperes each (10 total) and the taillights, dashboard, etc. draw very little (say 5 amperes total). The heater would be the biggest draw, around 20 amperes. Overall, you're looking at a good chunk of your alternator being free if you don't have everything on. I don't quite understand your RMS/peak and fuse theory. Using the fuse may not be accurate because many manufacturers use slow-blow type fuses, so you see 1000+ watt amplifiers with 60 or 80 ampere fuses, but the fuses can actually handle twice their rated capacity for a few minutes of continuous draw. A typical Class D amplifier is about 75% efficient at full output. A typical Class A/B amplifier is about 60% efficient at full output. Essentially, divide the power output at full capacity by the efficiency, then divide by the test voltage. For example, an amplifier is 75% efficient @ full capacity (1000 RMS with 14.4 volts). This means that current draw will be 92.6 amperes with a sine wave at full capacity and, obviously, less current draw at less than full capacity. The type of music you listen to is also going to make a large difference. People who listen to bass-heavy music (rap, trance, techno, etc.) should leave a little more space while those who listen to "lighter" music may even be able to use an amplifier that can draw as much as their alternator can supply. I forgot the rest of what I was going to say ... Damn drugs ...

    Need a Box for JL 12w3v2

    Donn, I could make better enclosures with my penis and testicles tightly taped to my leg while wearing an evening gown, lots of make-up, and my hair down on my date tonight ... I mean, awesome looking box

    take the 12volt quiz

    I got a pitiful 22 out of 30 (73.3%) ... I don't think I've ever scored that low on a test ...
