You need a bigger amp or smaller speakers.
The speakers are pulling more power than the amp can supply.

I have a Kenwood KAC-9105D amp with 2 Rockford fosgate 10 inch subs in a sealed box. When i turn the volume up loud the bass fades out for a few secs and then comes back to being loud again, this keeps...


It's the battery, not enough juice to supply your amp at loud volumes so the bass will drop out especially on long bass notes. Replace your battery!

Bass cut off when volume is too high


When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.

Good luck buddy.

Bass goes off when i turn up the volume


You need to install a heavier gauge wire to your amp and a capacitor. It works fine at low volumes because there is enough wattage from the battery to power the bass output of the amp but at higher volumes the amp does not have enough power.

Heavier gauge wire supplies more poer, and a capacitor stores a reserve of wattage for the amp to use so that it does not run out while blasting your tunes.

What duz level adjustment do


Hello,

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.

Hope this helps.

Bass sounds only


That is tricky one. Did you try adjusting the EQ on both the stereo and the amp? Is the Mute turned on because it will act like that? Is both rca jacks plugged in on stereo and amp?
