your in the right rca outs, right, last time i hooked up a system, i accidently put the rca's in da wrong spot, and no sound, that wuz my prob

do you also have a dash kit with the wiring harness?

Ya, The remote turn on lead is coming off the DIC adapter plug so im guessing its not exactly working right with the headunit.

I got everything straightened out today. 1. The remote lead is indeed not working...probably for the reason stated above 2. Had a bad ground, although it was grounding out, it wasnt enough for the system I guess and 3. I had to reverse the signal through the headunit for it to actually pump out the bass. Im not really sure how this last option works to be honest. A graphic representation on the screen shows one setup with a sub facing normal and then the other option is a sub reverse mounted. I assumed this was a representation of the flow of the signal so if you reverse mounted the sub then it would reverse the signal allowing the sub to move in the proper direction to create the right soundwave. Well, I have normal in box mounted subs but I have to use the reverse mounted option on the headunit for it to throw out the tunes...otherwise set to normal it makes sound...but no bass. I have a feeling if I were to turn off the LPF it would throw out normal music and end up damaging the sub. Very wierd but its all working now and I returned the XM2002GTR amp since it wasnt needed....it was a few extra watts but I didnt need it...got surround sound for the room instead, lol.

You are talking about phase change on the sub, it just reverses the direction of the excursion to create audio. They put that there because under some circumstances it will sound better, usually when you reverse mount subwoofers or in tight areas. You may have your cross over points set to high for it, check the settings on those and make sure it's actually enabled through the feed on the receiver. Some pioneers will show that is it but will disable it when you route it different ways. But double check the cross over points, could be the issue.

Unfortunately...im lost on the audiophile jargon...what exactly is a crossover? Im not even sure how to work the LPF settings. Ive got it set to filter out anything over 200hz (max of the sub) but I dont understand what the slope is (something like -6Db, -12Db, and -16Db), I go through the three settings and cant hear any differance so I just set it so that the slope bottoms out right at the intersection of the horizontal and vertical lines at the edge of the graphic...graph. Im not really sure what it is im doing though....if you'd like to explain that would be awesome...im always willing to learn something new.

A crossover is a device that takes a a audio signal, and filters the range at what is fed into the speaker. There are three types of crossovers - passive, active and acoustic. Passive is using a circuit that you don't need to power up, usually those little black boxes that you see with component sets. Active is something that is driving by a electrical source such as your deck in this case. And acoustic is purely the box which the speaker is in, which can be set to tune to a certain range. In the LPF settings like you have set, then yes anything over 200hz won't be fed to the sub and everything under that is what it will play down to the limits of the sub.

The slope basically comes back to the passive thing again, if you had is set at 0 it would be a passive set point and bypass everything. What you have it set at is I believe you have your HPF and LPF set at the same point, so the phase is reversed 180 since I'm going to assume you have it set at -12dB right? The graph just shows the line as which your crossover point is set, the bar on the slope is the curve at which that signal boosts the range which is it in.

Basically what I would do is go back into your settings and just turn your subwoofer off, do that through your deck. Then go through and play a nice musical CD and set all your HPF settings. Actually leave your sub on but turn it down all the way, but your HPS should be set as low as they can take it but with a gain that isn't going to damage them when you crank it up so listen to it at about 1/2 volume or so just to give you a better idea. Then go through and adjust your LPF settings which should be set somewhere relatively low, if you like the way -200 sounds go with that.

Now what amp are you running to the subs? I'm a little confused on how your setup is as you don't seem to mention what you are using. But basically you should be setting the amp controls for the sub first since it will control it better initially then your deck will. It sounds like something isn't quite right on the amp or connected properly such as inputs may be reversed.

Im using an old Sony XM2165GTX amp. Im not really sure if its even got a gain control on it...there isnt a dial for "gain" exactly. Its got a LPF settings on it which ive set to somewhere around 200 Hz (doesnt have it labeled for 200), the Pre-out setting to 5.5 since I was assuming that is to set how high of a signal the amp would be getting from the headunit and then Db boost maxed out. I had the Db boost zeroed out but it didnt really hit more then the speakers so I turned it all the way up...need to dial it back down to around 7-8 now I think. Other then that, there arent any other settings on the amp. Ive checked all the wiring, all positives and negatives are going to the right places so im not really sure why I have to have the phase reversed.
