Lost sound quality when installed new cd player?

[racin4JC]

Alright guys I am asking this question for my buddy! Recently his car got broke into and old cd player was stolen, it made factory speakers sound really good in comparison to the stock stereo. After insurance money came in he went out and bought another cd player (it is a Pioneer DEH-P7700MP) however, it is now installed and the factory speakers sound terrible (almost no bass, and hardly any mids or highs). We messed with all the settings that we knew of or could find in the manual and only minor progress was made. So do you guys know of anything else that can be done (besides a new player or adding speakers/subs) I am assuming with the settings or something we missed, any help would be greatly appreciated.

does the new deck have less power than the old one?

[racin4JC]

No it is 50x4 just like the other one.

What was the old deck?

[doubleN0alero]

You need to go back over your wiring...you messed something up...maybe you've got 2 wires touching somewhere or a bad connection...if everything else stayed the same, there's no reason for the loss of power...

[HazMatt24]

is there a loud option on the deck that needs to be used?

[racin4JC]

The old deck was also 50x4, the loud is turned on. My buddy installed it and it sounds like he did the wiring right but I will double check everything. Thanks for the ideas keep them coming if anyone knows somthing!

check the polarity. did he hardwire it or use a harness? harness is easy to check polarity, hardwire isnt. check for a short on a speaker lead also

[racin4JC]

He used a harness on it. What do I have to do to check the polarity?

and check the flux capacitor for God's sakes...:lol:

and check the flux capacitor for God's sakes...:lol:

definitely make sure it has a full 1.21 Gigawatts going to it.

did you blow out the factory speakers?

[sound_xtreme]

make sure all the colors are right. white to white, white/black to white/black, etc.

[racin4JC]

Speakers aren't blown, and will check double check his connections.

[trumpetplayer91372]

If you use the control called "volume" it will make it louder so there will be more bass/mids/highs.

[whiteliquid]

If he has a sound system a good mistake is with the rca wires...make sure red is connected to red on amp/cd player...and same with white/black whatever color.Thats sounds to me like the problem (if he has a system that is)

NVM post skimming and didnt see the FACTORY SPEAKERS part...so yea check you wire harness wires and make sure the power antenna is ran into the main power wire also.

What the hell were you getting at? Just havign the RCAs switched?

Im going to put my money on cancellation due to improper wiring- in other words a speaker, two, three or all are running out of phase.

Even if you have just one speaker running out of phase, it can dramaticaly decrease overall sound quality.

[racin4JC]

I will definatly check the wiring, but why do I have to hook the power antenna wire to the main power (I thought that was just used for power antenna's like on lincoln towncars or honda's). By the way this is on a 2000 Grand Am.

[whiteliquid]

if its the same as the alero you do....well i did anyways...

[racin4JC]

I don't think the power antenna affects it because I just put a cd player in another friends Olds Intrique and didn't use the power antenna and his sounds fine!

[sound_xtreme]

our cars have "power antennas" they HAVE to be hooked up to get good reception

[Ryan from Ohio]

ok, for thoose of us not totally in on this power anteena deal lease elaborate...

My antenna is plugged into my radio vial the coaxial wire. Now I got to power that anteena up.

Where and how?

That could explain my crappy ass reception...

[whiteliquid]

Take your wiring harness and run the power antenna wire into the main power wire (blue or red, not sure)

TADA

[bigd6983]

you gotta hook up the antenna wire off the harness(vehicle side) to the remote/antenna turn on wire(radio side)......its basically a unit that amplifys your antenna.......you will notice you pick up FM but has minor static and no AM whatsoever.........im pretty sure the antenna wire off the radio side is blue, if your using a wire harness so that you dont have to cut into the factory one, its probably blue on the other side too......

[whiteliquid]

No there is only one blue it is on the radio side, You connect it to the power wire (vehicle and radio side)

[sound_xtreme]

you can connect the power antenna lead to your power antenna(or remote turn on) lead out of your new deck. or alternatively you can tie the power antenna into the ACC wire.

[racin4JC]

I will also try this, thanks for the help so far.

I'm having this issue of no am, and I'm guessing it comes from that problem, we are learning everyday in here ty!

[bigd6983]

i said i wasnt sure......my car now both sides are blue. radio side is remote turn on and vehicle side is for the antenna.......both aftermarket harnesses have no color coordination with the stock wire harness which is why i said they may both be blue because remote turn on and antenna wire is usually blue.........

No there is only one blue it is on the radio side, You connect it to the power wire (vehicle and radio side)

[bigd6983]

and no problem........trust me i learned too.....i think i dealt with this for over a year before i found it out.......i never listened to AM at all until one day I wanted to catch a football playoff game or something.......and couldnt get anything.......

[jayson_waltz]

u probably got the + & - wires backwards on the speakers

[racin4JC]

If your refering to my original post, I still need to double check how my buddy wired it (it is pretty hard to screw up + and - especially since he has put at least one in in the past)but I am going to mess with it this weekend.

[racin4JC]

Hey thanks guys for the help we got it working good now, it turned out it was just a wiring issue so we fixed it up and she sounds good (for stock speakers)!
