Speakers push outward and hold that way when connected

When I connect my rockford p2 subs to my amp the cone pushes outward and holds like that almost like connecting a current to them. No sound is produced.

Hi, Make sure the connection are correct + to+ and - to -.
Also make the same connection to your amp + to + and - to -.
Make sure that your amp can run the subs, wattage and ohms.
Hope that helps.

Over excursion making flapping noise


try taking the sub out of your box its in and watch the coil and then push the cone in and let loose try that a few times and if the coil moves then your sub is no good

Which is the positive and negative connection on the back of the speaker


Normally the positive terminal is larger than the negative terminal. If not the case here, look closely where the leads route to the mid and tweeter. The terminal that leads to a cross-over component (capacitor) is the possitive terminal. (old school way of thought, but it works)

I have a Rockford PL2-110 and intermittently I get a loud popping noise out of nowhere. the sub sounds good the majority of the time but occasionally it will make the noise more and more often. any ideas?


Have you double checked the wiring ( + to + and - to -)? When hooked up correctly, a sub should push outward when bass hits. If your wiring is correct and your amp isnt too big for the speaker then its about to go out.

I have a rockford fosgate punch 150 and it will power a small 5 1/4" speaker, but doesn't seem to push my 15" subwoofer. I am reading 4ohms across the sub so I'm assuming that it is fine and that there is...


amp is way too small to power a 15 inch sub. But you should get some sound out of it, not silence. You can use a 9 volt battery to test your sub, if the sub pops when the 9 volt is placed across it's terminals then it's ok. If it does not pop then your sub may be bad, or the coil may be frozen. (It can still read 4 ohms if frozen). If your amp powers smaller speakers fine, you know it's not the amp. If the sub tests ok, then verify your connecting it properly to the amp's correct bridging terminals.

No sound after 35% power speaker just pushes outward


You will need to check that all your earth wires including to your battery are clean and have a strong connection to the body of your car. the other problem may be your trying to run to much power out of your amp and it is triping out. if you have to many speakers runnig or diff speakers running diffrent ohms off the amp( as in rear speakers and a sub off the amp your current draw on the amp will trip it out, for that you will need a bigger amp. Try your earth wires first.

Amp works on other subs, not on mine


Hello adeisenroth,

Sounds like the voice coil(s).

First make sure that the braided wiring going from the sub cone to the voice coil(s) have not come loose. Examine the braided wire all the way from the terminal to the cone. If one or more has come loose, it can sometimes be resoldered. Just be careful with the heat.

If all the wiring is intact, you can check the coils with a multimeter. With the sub disconnected, and the meter set to the lowest resistance scale, test across the speaker terminals. Depending on how the coils are wired you should measeure somewhere between 1 and 4 ohms. If you get "0" or no reading at all, one of the coils is open. If you get "infinity", a coil is shorted. Sometimes only one coil is bad and you can still use the sub, wiring it to the remaining coil only. Once you have determined that one set of coils is either open or short, you can remove the jumper and test each coil individually.

You can test most any speaker voice coil with a small battery. The best to use is the 9V type that has terminals right together. Connect a short piece of speaker wire to the sub terminals, and hold the other end of the "+" wire to the positive battery terminal, then quickly touch and remove the negative battery terminal with the "-" wire. The sub cone should move outward, and you should hear a brief thump. If no cone movement, and no thump, the coil is defective. Do not hold DC to a speaker for any period of time though, just touch and remove. And NEVER use a high-current battery, like a car battery for such a test. If the coil is not already bad, high DC current will damage it.

Either short or open, replacing a voice coil is a job for the Rockford-Fosgate professionals.

Multi amp hook-up


honestly i dont think those to amps will push cvxs no matter how you wire them up.
the rms on the 200 should be used to push a door speaker.
the 800watt should deff just be hooked to 1 cvx but still wont max it out.
