Bass speaker start up noise

Rockford is great for bass and your two way speakers. Alpine still controls the three way speakers that I would suggest for wanting the strong vocals with less bass. Too much bass bad so I would ignore most input from "audio" guys. They always over build the bass side, balance is the key.

Hi Haley,
I also enjoy good Music and excellent sound from my speakers that i have and know what you going through. There is two problems that i see here. One is that your bass speakers is dying on you from the excess bass that has been exerted throught it or have you tried lowering the adjusting bass from the contol panel?
Try adjusting the bass and if that doesnt work aleast you've identified your problem.
Thanks Haley for using Fixya.Good Luck.

G..

Maybe the capacitor in the power supply burned upon unplugging the heater. The power supply is a coil with iron core, next to it, there should be a rectifier and a capacitor. If the capacitor is burnt, the powersupply will still be working, but there will be noise on the line, the 50 Hz that comes out of your wall outlet. Capacitor of the same value can be bought for small change but has to be soldered in.

You have a possible fault in your wiring of the speakers, the Phases of the speakers are crossed over resulting in cancelling of the low frequency- bass frequency. Hence please reconnect the speakers front and rear with the positive/ negative to the corresponding positive and negative of the speakers.If you are unable to fix the marking of the polarity use 1.5 Volt cell to connect to the speakers , if the speaker moves up the terminal on the positve of battery is positive. reconnect and test with a good bass song for result. Helpful. Good day

I bought a Kenwood KVT-815dvd player and got everything hooked up to only find out that it had a security code. The problem now is that I got it from a pawn store and they did not even know that it had a security code on it. So is their a way I can bypass they password or just reset the whole unit so that it does not have one. Also, where is the memory for this unit?
Thank you

you probably blew them up,they are junk speakers and cant take much and then they die,its common,replace them

check your power or ground cable. this normally happens because it is not getting enough power

if desiring loud bass, keep port open. It is designed to be that way. If subs are in a corner, face the wall to change the wavelength and port noise wont be as evident.

Hi,

Offhand, could either be the subwoofer speaker itself or the electronics (amp and/or crossover). One way to determine is by physcially checking the sub speaker. When playing with bass on, pls try restricting speaker movement by pressing on it and see if the noise is reduced. Another is to temporarily replace the speaker. You can try speakers meant for the car, home entertainment or book shelf, just dont set the volume too high.

If the speakers are ruled out, then it would be the electronics inside. For this, you would need familiairty with electronic components and circuittry, a DVM and a soldering iron. Access to an oscilloscope and an audio signal generator would be nice but not a necessity. The idea is to inject a constant audio signal and determine where the noise (if electronic) is coming from. In most instances, it would be a leaky electrolytic capacitor either in the input stage or feedback loop. At other times, it would be also a capacitor in the band pass filter.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

hello, check and see if cabinet has loose screws or if back panel is tight,bass can vibrate screw loose.good luck! also look for anything caught in the woofer causing the noise.
