How many HOSTFS can you put on a Sub mask of 255.255.255.192
If 64 is the amount of HOSTFS that can go on a sub mask of 255.255.255.192
How do you arrive at that total and is there any band with restrictions with streaming HDTV files formats up to 1920 x 1880i on an intranet, not internet???

General:U may have turn it off/mute by remote accidentaly.ceck audio settings on the amplifier.Ceck on/off /volume button also located on the sub if apply.Ceck signal from the wiring with another woofer or multimeter (empiric u can do it by small light bulb 6-12v).If still need to open the case,remove the drive mask (textil/metal)by putting little pressure with a flat tool under it,under it should be the screws from the drive itself,can be taped with small caps.The box itself most likely it won't open.Caution:turn off ,work carefully not to scratch,use plastic tools,don't put large amount of pressure,the drive mask should pop easy.
Sub-Woofer pre out is for connecting that terminal to the input terminal of any sub-woofer. The sub woofer which it should be connected must be an active type [that is, there must be independent amplifier section built it with that sub-woofer; not mearly a crossover network].
riverray1969 it would help if I knew the exact model number of that JBL sub you are referring to. With that info I can provide exact specs.
Basically, you need to build/modify an sub enclosure that is suited for the sub, the music you mainly play, and vehicle tuning. Generally, sealed enclosures will provide tighter bass response and get decently loud. Some would argue that it will give you greater sound quality. A ported enclosure will give you a louder more booming sound. That depends also on where the port is tuned (ex. 32 hz, 36 hz, etc ). You need to make sure that the enclosure meets the sub's airspace requirement as well. A customized well made enclosure is just as important as the sub you put in it.
- kkkjohnson - Please clarify your question. Do you mean they stopped working all together. -First make sure the amp going to the subs is still working. -If not, stop and trouble shoot the amp (fuse, loose wires,etc) -If it is working, check the wires going from the amp to the subs -If the wires are connected, your next step should be to dismount the subs and hook them up to a digital multi-meter (DMM) To use a DDM to test the subs ohms do the following: Figure out what the specs of you subs are...ie...what ohms and voice coils the are (dual 2 ohm, 4 ohm, etc. After that, place the black/negative wire/lead coming from the DMM tol the negative terminal of the sub. The place the red/positive wire/lead to the positive terminal of the sub. Then set the DMM to the ohm symbol. It should look like a horse shore symbol. Then allow 5 or 15 seconds for a accurate reading of what the ohms are. For instance a dual 2 ohm sub should read anywhere from 1.6 ohms to 2.4 ohms...each sub is difference. Check both sides/voice coils if it is dual voice coil subs. For instance if your sub is dual 2 ohm sub and you get a read that is higher than the numbers listed above (ex. 8 ohms, .05 ohms, etc); this would indicate that you have a blown sub.
Hello. Quick answer...bad sub and amp combo due to fact that your sub needs a lot more power than this amp can produce (I'll explain later). But here is how you can do it: You can wire this dual 4 ohm sub in parallel or series. Parallel wiring would be to wire two the positive terminals on the sub to each other and wire two the negative terminals on the sub to each other. Thus wiring down the sub to 2 ohm. This what the amp would see. Series wiring would be to wire the positive and negative terminals on the same side of the sub to each other. Then wire the positive and negative terminals on the other side to the amp. Thus wiring the sub to 8 ohm. This what the amp would see.

Your sub specs are 1500 watts rms (how many watts your sub needs to operate efficiently or its minimum requirement. It has the a peak wattage at 3000 watts that it can accept in short duration. Your amp can only produce 300 to 600 watts at 2 or 4 ohm respectively. So you would be greatly under powering the sub which would produce a weak unfulfilled sound. You need an amp that produces a true 1200 to 1800 watts rms. There is a great selection out there.
The ip address is provided by your it department if you do not have an it department then you can select an ip address that is not being uesd example 192.168.1.200 this lus the sub net mask standard sub net mask 255.255.255.0 needs to be put in the network section of the machine then you can go to the c: prompt on your computer type in ping then the ip address you put into the machine you should get 4 replys and no drops then you will also need to load the print driver for the machine onto your computer
