The bass in my car magically disappeared...the subwoofer doesn't even buzz, does that mean the amp is blown??? but i checked the fuze on the amp and they are both ok....the sub wooker has a crack in the middle of the speaker, but the one crack couldn't cause it to not work. So i hooked up another woofer to test it and again, no sound...is it the amp? could it be lose wires? i think not because ebay installed them? the cd player? the crack in the woofer?

if you turn the bass setting in your radio down it will take the bass out, but may take some of the bass out of the subs as well, if this occurs and you still are not satified, you either have to get a car receiver with a non fading subwoofer preout, or you could get bass blockers for all the speakers you dont want the bass in
yea for sure thats a good upgrade. You shouldnt havebeen able to blow the kenwoods with 400 watts though-meaning that they probably blew from distortion which causes heat(fast) Check your gain on the amp start it out at 1/4 gain and turn up your deck to the point where you can hear distortion from your mids and highs or to the maximum level that you listen to your music at. If you're jamming out at a level that is causing distortion then you will be sending a distorted signal to the amp as well. The amp then amplifies the distorted signal through the subs which overheat and blow. So find the distortion spot and then turn it down just a little bit till it clears up your sound-then adjust your gain on the amp up slowly until you cant hear it getting any louder. Once you have done that you have reached the limit of CLEAN power that you are going to get.Thats where you want to keep it. Watch the bass boost too if you have the bass up on the deck and then crank up the bass boost on the amp it really f's up the signal too. Good luck
On the JBL3501 700 watt monoblock, you have adjustments for low pass and a setting for boost marked DBO, allowing you to select and boost the frequencies sent to the subs. If your amp is not the 3501, but a different JBL amp, the settings may be different.
Set the LP to either the white dot (about 100Hz) or slightly below to about 80Hz. Set the HP to about midscale or slightly higher. Set the boost to wherever the bass sounds best.
One other setting that will affect bass volume is the "input level" or gain control. It should have been properly set by your installer, but you can "tweak" it for best performance. Turning it up increases the sensitivity and matches it with the output from your head unit. Too high will cause distortion. Too low will result in less bass. So you want to set it just to the point that you begin to hear the distortion and then back it off slightly until the distortion disappears.
Hope this helps.
The level control controls the input level coming from your head unit (receiver) to the amp.
Your Sony users manual is a little vague on how to best adjust the level and other controls.
Here is one method that some installers use and works well with most amps.
Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.
As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)
But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)
Here is a link to your manual for the subwoofer. http://www.kicker.com/sites/default/files/SoloBaricL7Series.pdf
So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)
Consider yourself lucky if your subwoofer is still working without issues.
hard to tell whats causing this .Just curious make sure speaker wires going to subs are POLARIZED meaning positive from amp is with positive at woofer and NEGATIVE is with negative at woofer.When these are crossed and when volume is raised you will hear the bass cancell each other out..
You need to look got the amp for the sub if there is not one there is notting you can do. If there is one then just turn up the gain on the amp.
If not there are some times the gain is on the radio in a setting and the only way to find that is to look in the user manuil.
