Question about Alpine CDA-7995 CD Player

Open Question

I have an older model high end alpine cd deck. It has rca sub outs front and reat rca outs as well as high level straight wire outs. It also has the standard power antenna wire and remote on wire. It also has large gauge RCA type wire with what is called a dc to dc converter. Does anyone know what this is? What does it do? And Why does a dc powered vehicle deck need a dc to dc converter? The unit was installed and performed nicely in my 65 GMC pick up w/ some MTX 4.25's. I have yet to try the other function. The entire time it was in the truck, the dc converter was not attached to anything and the manual says nothing about it. I'm going to do a complete more advance install w/ the unit subs, amps and cross overs. Will I need to attach this converter to something somehow? There are no obvious plug ins or places to attach wire to the converter and again.. the manual says NOTHING about it. Any information would be greatly appreciated.

SOURCE: no sound to the in car speakers from my alpine cda-9827 cd player

What kind of car did you install this in? Did it have a factory radio in it? If I had to take a guess I would think that there is a factory amp that you may have hooked the blue wire from the alpine deck to. If this is the case when you switch to CD the alpine deck turns off the power to the power antenna lead(blue wire) and thus your factory amp. If this is the case hook the factory amp turn on to the blue and white wire and you should be good to go.

SOURCE: How to wire a stereo system

Connect the 2 gage to the battery thru at least s 50 amp fuse, then connect the capacitor in line before the amps. Then run the 2 gage to a connector/splitter block and run 4 gage leads to each amp. You also will need at least 4 gage ground leads from each amp to a body grounded bolt or screw. You need to run a quality set of speaker leads from the head unit to the amps. The speakers will need separate leads from the amp to each speaker.You will need to try some different combinations to get the sound and bass you want. You want to be able to fade from front to rear and control everything thru the head unit.
Use a hole saw to cut a 2 to 3 inch diameter hole in the side of the speaker box for a port to get a better punch from the sub.
Hope this helps some....

SOURCE: Still no sub woofer output

SET THE CROSSOVER TO "L.P.F."POSITION AND SELECT THE LOWEST FREQUENCY AS THE CROSSOVER POINT.
[AN AMPLIFIER IS SUPPOSED TO "AMPLIFY"(TO INCREASE)ANY OUTPUT.]

TRY CHANGING THE POLARITY OF WIRES FROM AMPLIFIER TO SPEAKERS /SUBWOOFER.{it leads to cancellation of bass output.}
if u still have doubt contact me again.

SOURCE: connect alpine 7874 to alpine powered sub

You need to run the RCA cables from the head unit to the sub for the audio signal, and possibly a turn on wire (the blue one on the back of the head unit), unless the sub has an automatic power feature.

The sub also needs power and ground wires attached, but those do not connect to the head unit. Power should be run directly from the battery with an inline fuse, and ground should go to the nearest good ground point (Trunk latch, seat bolt, etc).

Ok i got a mtx 12' 500 sub matched to a alpine mrd-m500 mono amp. The deck powers the 4 speakers, as i turn the volume up on my deck (alpine cde 100) the sub/amp cuts out at around volume 20-22 and E-3...


Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg

Hey I have an Alpine CDA-9851 CD Player and was wondering how to hook up my two 10" Kicker subs, since there is no subwoofer connection on the back of the player.


First to start you need an amp something that is a little stronger than your subs. What you want to do is 'T' off your speaker wires into RCA's to hook up into the amp. There is a device you can buy or you can cut some RCA cables. There are a few down sides to do it this way because as you turn up the volume the Subs will get louder and start to distort a lot faster than hooking up proper. The best way to do it is to get a deck with RCA sub outputs. Good Luck

I have an Alpine MRD-M605 amp that recently has started having issues. My subs only produce sound when my deck is turned up full blast. The setup had been working for over a year with no problems. The subs...


If your deck is aftermarket; Does it have a dedicated Subwoofer output? if so, check the control in the deck (sub gain). If you are using a factory radio, and a high to low level adapter (speaker wires to RCA), it may be bad (not too uncommon) or check your fader front/rear any difference? Otherwise, you have one of two problems. A bad preamp in the deck or a bad pre amp in the amp. Both are fairly uncommon. More than likely it's a setting. Hope this helps

Alpine sub pre outs


i know people dont like doing it this way but when in doubt, splice wires.

go to walmart and buy a crossover, splice your front or rear door speaker wire and wire in the crossover and also the door speaker. plug your RCA cables in and run them back to the amp.

most people with stock decks do this if they dont have sub out or amp out.

if u need more help let me know

Hooking the mra-f350 to my highs


You will only need to connect the door speakers to the MRA-F350. In short, the connections will be as follows:

Deck---->MRA-F350 amp---->Door speakers
...................................\---->Sub amp---->Sub(s)

Just make sure you use the optical digital output of the deck to connect to the optical digital input of the MRA-F350 amp, not the RCA preamp connections.

Swapped out cd players now getting high pass through subs


this is very easy...just unplug the rca cables out of the back of the deck, and plug them into the "subwoofer" output. On some alpine decks this is on a "pigtail" wire that extends from the deck. Once this is connected to the right output, you can control the subwoofer level from the volume knob by pressing it inwards.
Also.... your amplifier should have a low pass filter, it should be on a switch marked "LPF". Make sure this is switched on.
