Outta phase? if a tweeter is out will make sub distort?

Also, if one tweeter is outta phase with the other, (since they're wired in series) will that still sound or will it be silent?

A Tweeter being out of phase should not have any effect on the sub.

If one tweeter is out of phase with the other there will still be sound in the room as due to the high frequency the unequal time to your ear will mean you won't get perfect destructive interference and the signals won't cancel. Also the two tweeter signals convey much less information in common than a subwoofer or bass speaker.

There are 2 wires from crossover to Acoustic Research Phantom 8.3 Titanium Tweeters. One wire is Brown, other Green. Tweeters have one terminal marked with red paint. Some of my speakers have Brown wire...


Normally Speaker and Amp side will mark correctly the polarity. If wrongly connect phase may get wrong. If you understand or may know the different by hearing, if both tweeter phase is wrongly connect, what need to do is reverse the connection of one side the phase will change. you can try which give you the best listening feeling.

Both tweeters on one of my Bose 301V speakers have stopped working. Is it possible that they failed together or is it likely to be a crossover problem?


Since there is no single crossover for two speakers it is likely both speakers experienced the same audio trauma and blew together. Something like microphone feedback will take thenm out in a literal heartbeat.

The 301's sometimes have an element in series with the tweeters that looks like a little light bulb (or it could be a fuse, too) and it is designed to blow before the tweeters die. They're easy to find if you remove the woofer to get some maneuvering space inside. If they'rethere and blown (visible) you can either wire aroundthem and be careful in the future or get some more.

Do a web search for "tweeter protection fuse".

If the tweeters did take the hit get on eBay and find some more, plus think about installing protectors if you can't avoid excessive distortion or power going to them.

Regarding pwoer vs distortion, the latter will kill tweeters in a blink so don't think a modest amp is safer than a powerful one. The modest amp will distort sooner.

How do you replace rear speakers in a 2002 Alero?


Put the + from the "sub wire" to the + on your new speaker. Put the - negative from the "tweeter wire", to the Negative of new speaker. Now, take the Neg. from "sub wire", and connect it with Positive from "tweeter wire". This is called wiring in "Series". This keeps the ohm load at a level safe from overheating your speakers. Click this link: http://bcae1.com/ put "series wiring" in a search on that site, and the page will come up that has a picture, as well as info of why you should wire them like that.

My cerwin vega xls215 tweeters fade out at high volume but not distorted volume


There is a polyswitch in series with the tweeter. when it gets hot from lots of current running through it, it goes high resistance, attenuating current to the tweeter.
Remove and bypass the polyswitch if this annoys you, but then you risk blowing the tweeter if you run it too loud!

Subwoofers pop then immediately produce no sound


Sounds like the two subs wired together might be too much of a load on the amp and it is shutting off. Try wiring the two subs in series. That will reduce the load on the amp but will conversely put out less power. Less is better than none though. In any case check your amp to see what the lowest ohm rating it can see, that ohm rating is where you want your subs and if faced with a choice of either going under (lower numerically) or over (higher numerically) GO OVER!-it is much safer.
Here's an article I wrote that can help explain how to wire the subs to the amp.

OHM LOADS, SUB WIRING, OHM RELATED POWER OUTPUT

SERIES SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the negative pole of the other voice coil (on the same sub). This will leave you with a positive pole from one voice coil and a negative pole from the other giving you the two leads that will be hooked up to the amplifier or other subs. When wiring in series, the ohms will go up numerically, and the load on the amp will go down. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

PARALLEL SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the positive pole of the other voice coil (on the same sub). Then wire the negative to the negative in the same way. You can then wire to the amp or other subs. When wiring in parallel the ohms will go down numerically, and the load on the amp will go up. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

MULTIPLE SUBS USING SERIES AND PARALLEL WIRING
In order to match your amplifiers ohm rating you can use parallel and series wiring together, just keep things even for power distribution and to avoid phase issues.
Example: I have two “Type X 12” subs” that have dual 2ohm voice coils and have to match my “Amplifier X” ohm rating of 2ohms mono. In this case, I would wire each subwoofer in series (giving me a 4ohm load), and then wire the two subs in parallel to get my 2ohm mono load. When wiring multiple subs just, treat each sub as a voice coil and wire accordingly.

POWER OUTPUT AND OHM LOADS
For example if “Amplifier X” can make 100watts@8ohms, it would make 200watts@4ohms and 400watts@2ohms. However with every drop in ohms the amplifier is put under more pressure. It starts to create a lot of heat, distortion figures begin to climb, damping rates drop, and some amps even throw power spikes when clipping. SO BE SURE TO CHECK YOUR AMPS RATING AND DO NOT EXCEED IT!

How can i get a 2ohm load outta 2 4ohm dvc subs can you show me how to wire the amp as well it says on the amp its 2ohm stable


A normal wiring setup to produce a 4-ohm load is what you usually see - each speaker is wired to one channel of the amp. This is series wiring. To get a 2-ohm load, you need to wire in parallel. Here's how:

Take sub A and wire the positive terminal to the positive terminal of channel 1 on the amp. Wire the negative terminal of sub A to the negative terminal of channel 2 on the amp. For sub B, it's the opposite - positive terminal of sub B to the positive terminal of channel 2, and the negative to the negative terminal of channel 1. That's parallel wiring, and will produce the 2-ohm loading (and subsequent increase in output) that you're seeking.

Apline mrv-1000 2 infinity sub


RMS power at 12V 20Hz-20kHz
2 x 100W @ 4 ohms (0.08% THD)
2 x 200W @ 2 ohms (0.3% THD)
1 x 400W @ 4 ohms bridge (0.3% THD)

That amplifier is not 2 ohm mono stable in bridged mode (assuming subs are SVC 4ohm).
It is seeing too much resistance and overheating. Thermal overload protection kicking in.

The phase switch allows you to switch from in phase to 180* out of phase. This feature is not to taken as written in stone. In some rooms, or locations of a room, the output will sound louder/better either in phase or out of phase. So there is no correct setting. It all depends where the sub is located and the acoustics or shape of the room.

Phase is term that describes multiple characteriscs and behavior of a speaker system.

Phase alignment: The vertical alignment of the voice coils of all the speakers in a speaker cabinet, so that all signals reach the sweet spot at the same time.

Crossover phasing: If one or more crossover slopes are of a different slope, then the speakers would not fire at the same time, causing delays in response.

Reverse polarity: You may reverse the polarity of a speaker to make the speaker fire inwards instead of outwards to improve alignment with the other speakers in the system. This is very common in tweeters circuitry. As for woofers, if the polarity is reversed, there is usually a cancellation of bass, to a degree.
