sub cuts out

Re: sub cuts out

Where are you getting the audio from? Pre-amp out on your receiver or leaching off a speaker wire?

Do you have the single or dual voice coil sub? There were two versions of that sub. If you have a dual voice coil, run them in parallel, the amp can take it (2ohms) and it is a lot better electrically. (even load)

Did you get it at BJ's? :D They have a thing for pioneer.

Also some better pics of the setup would help.

Re: sub cuts out

I think I found your amp's specs online, and it doesn't look like you have pre-amp inputs. If you are running off your speaker level wires from your head unit, it is probably the head unit cutting off. The amp can only replicate what it's given and so the cut sound is amplified.

Re: sub cuts out

How many ohms stable is the amp? Is the sub a DVC and how many ohms per coil? How is it wired? My fiance has a system in her celica and she had the same problem it would work well, hit nice and tight but when she went to really pound on it it would go into protect mode. It turned out that the sub was wired for lower ohms than the amp could hanlde and it still be stable. I switched it around to the correct way to have the amp be running a stable ohm setup. Personally i dont think that it is a lacking power issue. I have two pioneer 800 watt premier amps 2 ohm stable each powering a 12 inch 1200 watt pioneer premier dvc, 4 ohm coils,wired in parralell at 2 ohms. I pull my battery gauge all the way down to like 9.5 volts and i have yet to put them into protection mode even with that little juice going to the amps. Just my 2 cents though.

i don't think i can really ground it back there. i already use that ground for a few other things. i don't want to put too many grounds back there. anywhere else you think would be good?

Re: sub cuts out

Although amp mounting location can easily play a role in amplifier overheating, it doesn't automatically mean you're amp will be in the clear. (I didn't read every post, sorry if I'm restating something) If the actual impedance of the subwoofer is below the rated impedance of the amp, the amp will often play fine at low volumes when the power requirement is low. When you crank it, the amp overheats very quickly and kicks into a protection status. A very similar situation can occur with low voltage. When you crank the music and the power demand is high, the voltage drops below what the amp is rated to and kicks into an under-voltage protection. (used to happen on my old Fosgate bd1000a1) Do your headlights dim when the bass is played hard?

We need you to crank it, wait for the sub to cut out, and then immediately take a look at the amp. See any protection lights? Does the power light change color?

Do you have a multimeter at your disposal?

when i go home i will go into the garage and put the lights on and turn it up.

i've never seen the light be anything except blue. we just moved so i have no idea where our multimeter is.

it was from ebay.

what does Pre-amp out on your receiver or leaching off a speaker wire? mean? i'm telling you i really don't know anythign about audio.

it is a Dual Voice Coil. what do you mean runn them parallel?

what kinda of pics would you like? i can take more.

Re: sub cuts out

Did you run wires directly from the back of your stereo to the amp, or just attach a wire to the existing speaker wires?

If you have an aftermarket stereo, it should have two extra connectors on the back that look the same as the ones on your TV (one white, one red). You should run wires from these connectors to the amplifier's input connectors.

If you just spliced in some wires to the existing speaker wires, it will sound like s* and you should re-wire it like I described above.


As for the amp -> sub connection, you should have it wired like this:


It is easiest to run two wires to the sub, and use 2 smaller wires to connect the two coils' + and - terminals.

Re: sub cuts out

ok well the lights are dimming just a little big when the bass hits. also the battery needle does jump a little too.

here is how the sub is wired

Re: sub cuts out

Your drawings are the same. The subwoofer's two voice coils are in parallel to the amp. Regardless....

Being that everything works fine under normal volumes, we can be quite certain the amp is kicking into some sort of protection (most likely thermal). Again, we need you to watch the amp when it cuts off. Let us know what happens.

If the amp IS going into thermal protection, you can back off the gain a touch and maybe bump the "bass" setting on the headunit down a touch. Then pump up the volume and DANCE! DANCE! DANCE!

Re: sub cuts out

Where are you getting the audio input for the sup? Again, with the setup she has there shouldn't be any clipping on the amp side; but if the input could be getting clipped by the head unit.

Please take pics of where you wired the inputs. I'm still betting it's because she is taking her input from the speaker level instead of the preamp out. The HU won't reproduce low frequency at high volume (without clipping) and thats why you need to use your pre-amps.

EDIT: What kind of head unit (stereo) do you have?

Re: sub cuts out

here a link to my head unit.

i have the lines running from the back of the head unit(i believe it said subout or something like that. i dont' remember since i've had this problem for the last year and a half) i will check when i go home.

Re: sub cuts out

there is a whole list on outputs on that page. which should i be putting the intos into?

i believe that it's pluged into the Gold-Plated Subwoofer Output Terminals with Level/Frequency Control. which one should i try?

[GinsuGuy585]

Re: sub cuts out

Yes it should be connected to the sub out terminals. If that is set up correctly then I'm not sure. The setup should be able to pound close to unbearable levels without cutting, unless the music you are listening to has poor/no bass. Try burning some of these songs to a cd and play them. They are fun to listen to on a home theater setup too. :D

Re: sub cuts out

I bet it has something to do with the fact that she has no box.. it's just kind of sitting in the seat delete... since it will be quiet, maybe she turns it up and then the amp overheats.

[kristen]

Re: sub cuts out

its not free in the box. it has a box inside the box that surrounds it.

come on guys give me ideas. i will check when i get home to see if the lights are chaning. but i've never seen them change before.


what settings should i have the amp on?
