hey fellas!! what would sound better.
2 subs with 2 amps and they are mono amps and the radio
has i rca for a sub will have to use a y rca.
OR 2 subs 2
mono amps and the radio has l & r sub woofer rca outputs.

mono or stereo
every sinse i been into systems i always used 2 subs with l & r
sub outputs. i tried the 1 mono sub a few times and same result
a hole in the lower bass notes in the music. ( lets see) with l & r
outputs the subs play more of the bass notes as with the 1 rca mono output the subs plays every other bass notes in the music.
this is what i hear and i can't stand it. the box is divided

Ok dude, just cause I care, I'm going to explain it to you.
Below 500 herts our ears start to use timing to locate where a speaker is located.
At 80 to 100 herts its the only way our ears can locate the position of a speaker.
Have you ever sat in a car and the sub sounded like it was in front of you?
Don't answer that, I all ready know the answer.
Either way, its simple to do. Match the phase of both subs so that your x over points between your subs and mids blend well when the sound waves hit your ear.
That being said....
If sub base, or freqs around 80 to 100 herts were recorded in stereo, it would make it even harder to properly blend your mids and subs.
Not only would you have 4 path lengths to deal with, but you would also have 4 diffrent absolute phases.
(Absolute phase, is the phase at which a sound wave leaves the speaker)
(Relative phase, is the phase of the same sound wave as it arrives at your ear)
Relative phase is a variable. If you change the distance from the speaker to your ear, the freq, or absolute phase, your relative phase will change.
Cancelation is another reason you don't want your subs doing their own thing (ie, playing in stereo)
The slight variations between left and right channels at higher freqs would destroy your low end output if sub bass was recorded in stereo.
Think of it this way. You have two speakers at a diffrent distances from you, playing the largest sound waves you can hear and reflecting off of everything. Any time those two waves cross and your 180 deg out of phase, your going to get cancelation.

One of your subs is wired 180 deg out of phase from the other.
If you don't beleive me try this.
Take a simple 9 volt battery.
Disconect both of your subs at the amp.
Touch the positive to the positive, and the negative to the negative.
if your sub moves out your good. If it moves in then your wires are swapped.
they are not out of phase i thought so too. I had a bad y rca for the
subs. I hooked them back to the 1 sub rca from the radio and
really now i can't tell the diff from the stereo rca from the mono
way. I'M happy now thanks. now i need to think about using
the center channel output, what speaker,locationand a amp.
i have a yukon and theres no room above the radio to mount a spkr
on top of dash .
