Re: no bass thru cd player

It seems like you connected the wrong remote wire to the amp.
Alpine has two remote wires.
BLUE (only) This is the pwr antenna remote wire,every time you insert a cd this remote wire,the pwr cut out.

What are the best settings for bass , treble and mid in order to get the best sound

There are no hard and fast rules for setting Bass, Midrange and Treble on your radio. Depending on the type of music you are listening to with your radio, it can / will determine your sound settings. To attempt to set the sound settings on your radio, select the sound settings and set all of them to 0. ( Bass,mid,treble ), then start playing your usual music. With the music playing move the treble setting in single incriments 1,2,3,4 and so. A comfortable setting is usually a 5 out of a total number of 6. Then move over to Midrange and repeat process. A 4-5 out of 6 is usually comfortable. Finally comes the Bass. You do not want to overpower your speakers with too much bass as this will damage them over time. Repeat the usual process and listen carfully for any baffling or distortion as you move through the numbers. A comfortable bass setting is usually 2-4 out of 6. Again I must stress that there is no hard and fast rule for settings. It boils down to the type of music, and what your ears tells you sounds good. What sounds good to me might not be enough for you, or vice versa. I hope this helps! Cheers!

I have a Alpine CDA 7892 CD head unit I just installed and the radio works perfect but when I play a cd it sounds very muffled and I can hear bass only. Is the unit bad?

If the sound is coming out clearly with the radio on, then there is a problem with the cd drive or its connections. If your stereo has aux. inputs, you could run an mp3 player until your ready to replace it.

Poor sound

Sit low Bass @+3 / Mid@ 0 / Hi+10
Add SubWoofer with separate Amp and use low pass filter @78hz cuttoff.
It's a cheap unit -don't expect High Fidelity & a warm EQ<

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?

No sound thru cd player

are you using any separate amp?- if you are the blue wire on the back of the radio is probably turning off when you use a cd(the blue wire is for a power antenna, the blue with a white stripe is for an amp)

Amp and sub bass playing through all speakers

You need to go into the setup menu and find out if the radio has a sub low-pass filter that redirects the bass to the pre-out for the subs, and away from the main speakers. Fiddle in the audio menu.
