I think that was the main thing that I was hoping for was letting ME know that my car was being tampered with. Right now, someone could break in it and I wouldn't even know until I got up in the morning and went out and saw it. With the alarm, everyone else in the neighborhood will know, SPECIFICAL...

On another Scytek alarm, it includes a "Dual-Zone Dual Adjust Piezo Sensor". What is that? That alarm is 180$ but includes the starter kill and all that good stuff as well. While I can't speak for that brand, a dual-zone adjustable shock sensor typically can be user adjusted (by a set scr...

I've had a 2 way paging alarm for almost two years (and live in a bad neighbourhood). Thieves have been in/tried to steal my car a number of times prior to the alarm install. I've had the warn-away triggered a bunch of times and the alarm triggered a few as well since then. Alarms haven't really got...

While I can't say I've heard all the choices you've mentioned, I have the Polk SR 5250 and like them very much. I've spent some time with the SR6500s, too. If I could have fit those in my car without a whole lot of custom work, I would have gone that way. The Polk SRs could be summed up as smooth so...

The only other thing I would like to touch on (after what basic said) is the need for some gap between x-over points. This area is just as important as slope. You need to alow for a gab between where the sub starts to roll off, and where the mid starts to roll off. IE sub set to 60 herts, and the m...

That's what I assumed, but I wanted some kind of answer as to if there was generalities or that is one of those install-specific things. Definitely install specific. Your xover slopes depend on the frequency response of the drivers in your system, your type of enclosure (components in an infinite b...

For example, let's say your front component speakers play nicely down to 60 hz with most music you listen to, and you are using a 12dB/octave slope on the crossover point of 60hz. Let's say you have your sub crossed over at 80hz, and are using a crossover slope of 6dB/octave as well. Now with those ...

Page 16 of the manual (hard copy that came with the 9813). There's a slider switch on the 9813 to select either 2-way or 3-way for the crossover. If you're using 2-way (high pass/low pass)... Press and hold T.Corr/X-Over button for at least two seconds. Press Band/Tel to select desired parameter: Lo...

What kind of car? Some cars have adjustment at the idler (to compensate for slight differences in belt length, but also works with slight differences in pulley diameter). Some cars (Ford comes to mind) have zero adjustment, and when the bearings in the idler start to wear out they make noise. It cou...
