all i can say is check each and every wiring you did again. it's bound to be in the wires. otherwise you get one bust sub or something.

That sucks that your mom won't forget about the ticket for a day and congratulate you on getting into college.

About your sub...if you're changing the x-over and your rear speakers are changing, then that means you have your rear speakers wired to your sub amp or you're hearing things. If your sub just cuts out...did you check the wiring inside the box? It's happened to me on at least one occasion where one of the wires connecting the sub inside the box has fallen off. If this happens then the sub won't work...so check that out. Other than that, if you've checked out all your other wiring and you're POSITIVE that it's all good I don't know what to tell you...could be a busted sub...or maybe somehow your sub is putting your amp into protection??

Check out the wires inside the box and if that's not it post back...but I have a sneaking suspicion that's it if everything else is wired and your amp still powers on.

wait...so you plugged her sub into your amp?...if it's a powered sub is that even possible? I thought the amp was wired directly to the sub in powered sub enclosures.

If you did in fact connect her sub correctly and it didn't work, then that means there is something wrong with your amp.

If you're trying to test another sub with your amp, the only thing that should be connecting the two is a positive and negative speaker wire...everything else should stay plugged into your amp the way it is...don't move the RCAs, the power, anything...just the speaker wire. If the other sub doesn't work, then your amp has something wrong with it.

You can also do this with your sub...find someone who has an amp (not a powered sub) and hook your sub up to it. If your sub doesn't work then your sub has something wrong with it.

protection goes on means that your sub is wired wrong most likely...or you need to double check your amp ground because it's probably no good.

If the amp worked when you bought it...did you buy it today, or yesterday? Sometimes amps are defective...and if you abuse them they will break...do you think that just because it worked when you bought it that it will work forever?

Tell me what kind of sub you have, how you have it wired, and what kind of amp you have.

also, like i said...you never know when you have defective equipment...and it doesn't always just wear out...sometimes things break instantly.

check the amp with another sub and the sub with another amp to see which one is causing the problem like I said...it never hurts and it's a way to eliminate one of the sources of the problem.

I'm about 99% sure that won't hurt your amp...if the ground wire isn't connected to the ground terminal on your amp then there's no way power would go through it at all...let alone through the output.

If the amp is 2 channel, and your sub is wired to 2 ohms and you have the 2 channels bridged...that would cause it to go into protection. try connecting the sub to only one channel of the amp.

I'm not positive...but I had an old poweracoustik amp and I did the same thing back when I had my first system. Plus, most 2-channel amps, especially in that price range, aren't 2 ohm stable when bridged. I'm almost positive this is your problem unless the PA amp is a mono.

Sorry about not responding...my main posting is while I'm here at work so I was gone.


First of all, the spark is fine...it didn't (or at least shouldn't) fry your amp. It just happens because you didn't disconnect the battery before connecting the amp. Basically it's like the spark you get when you plug something into the wall that's already turned on. You're completing the circuit while the wire is already live so that's what makes the spark...definitely once or twice won't hurt anything...just disconnect the battery from now on before you mess with your amp.

Second...if you have dual voice coils, and only one of them is connected, this is VERY VERY BAD for the speaker. Depending on the impedence (ohms) of your voice coils you'll know how to wire it. I just looked up your sub model and found you have dual 4 ohm coils. There are really only 2 ways you'd want to consider hooking your sub up.

1) put your amp in mono mode, and connect one voice coil (1 +&-) to each channel of the amp.

2) the second way (and the way I recommend) is running your voice coils in parallel which would give you a 2 ohm load. And then connect the + and - terminals on the outside of your box to ONE CHANNEL of your amp.

your amp should have outputs like this

| + | - | + | - |

^...^ (connect it to these 2)

and to wire your sub in parallel, you need to wire both of the +(red) terminals on the speaker together then to the + on the terminal cup on the box. And then do the same thing with the -(black) terminals.

try rewiring the sub like I told you and if it doesn't work then I'm afraid you might need a new sub...just tell me if rewiring it works and if not maybe we can try some other stuff...but I'm just preparing you for 'the worst'.
