No Bass When I plug my L455-S5975 into my cars audio input I have no bass.

Have you checked the battery? Put a brand new one, if that's not the problem, take it to a reputable tech.

If you have a Phono input it will provide the additional amplification needed for the ceramic cartridge, and perhaps even more amplification for a magnetic cartridge, made available by a switch. It also has extra bass boost to counteract the lack of bass in the recording, done so as to keep the grooves from making use of lots of platter real estate. By minimizing the bass, the recording time is increased.

If you don't have a Phono input, but you have an aux input, you may have to crank the volume and the bass to get reasonable sound, because the phonograph cartridge doesn't produce much output as compared to "line-level" devices such as a line-out on a tape deck.

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.

lets see so if u got the bass up with no swicth it hits like it should , try cuple things the swicth itself make shore there is nothing in where u plug it in on both ends , try ur acr wire unplug an plug them back in while the bass is off , try swicthing the controll wire around if able. i have had a amp that did something like that but i never had a controll hook up an it would hum when musice was off because the input for the acr wires was messed up . i hope this helps u out thank u

Most likely problem is related to the FN key software. Try downloading the drivers from http://support.toshiba.com

wish driver should i download to get my fn key back to work?

reason is there is separate bass on both input channels that you want to include in the sub channel. For example, if bass drum is on left channel and bass guitar is on right channel, you need both to hear all of the bass music from your single sub. OK?

I am guessing the bass control is just a potentiometer that you plug in. It could be open and that is why the bass dies. As far as the switch goes, I am not familiar with the amp but it sounds like a crossover between low frequency and subsonic frequency.

i had the same thing happen to me on my 2300hct audiobahn. it turned out to be the remote. but soon after my amp went dead. i than switched to JL no problems since.

but i still use audiobahn immortal 12's.

Hi Jamesroy,

Remove the Audio inputs from the bass box to see if the thump is coming from the Audio input. Of course do this with everything turned on. What we are trying to figure out is where the thump is originating from. If the bass box does not thump when the audio inputs are disconnected, the thump is coming from somehwere between the bass box and the circuits inside the head unit.
If you still have the thump after the Audio input wires are disconnected, then your bass box's amplifier has noise problem. You might try getting a noise filter from best buy to put on the power supply feeding the bass box.
