another question... dont most systems sound better with a closed trunk?

i am using 2 cheap 12's in a bandpass right now (first bandpass, usually sealed) that i borrowed from a friend, and they get twice as loud if i pop the trunk...

and yes, bill, i looked in the service manual under: speaker, wiring, nothing came up

I can't quite see that right rear you are looking at ..cause it's on my laptop...can't get it on my desk...but they give pos and neg. ;)

well i had it right then.... damn

how about my other question

maybe if you solder them you may get a better signal instead of those clamps

You got a pic of the bandpass? I've seen many boxes that are called bandpass that aren't bandpass. Thats why i'm asking for a pic.
Does the box take up all the room between your strut towers?
Do the ports face the tail lights or the speaker deck?
What size and how many ports?
All these factor in on why the sound changes when you open the trunk. It all has to do with the pressure caused by speakers and how it's put into the trunk by the ports.

If it sounds better with the trunk open you're out of phase. Look on your speaker connectors, are they marked with a little "A" and a little "B"? I know 99% of the gm cars were. If they are, "B" is +, "A" is -.

hey do you have the bose stereo??? and if so are you runnin a line convertor??? i had a prob with mine bit figured it out.....

here is the line convertor, its turned about halfway up right now, and the amp is all the way down, at about 80hertz

Theres the reason. Your ports are muffled by your rear deck. When you open your trunk, your making it easier for air to move, therefore your speakers are moving more and your getting more bass.
Here's a test. If you got a video camera, put it the trunk (with the system on) with the light or nightvision on and close the trunk. Then open the trunk and watch the tape. You'll see a huge difference in how much the subs move.
Oh, and why is the remote gain control in the trunk?

so you think if i run with the box in the back of the trunk it will perform different?

the remote is there because i dindt wanna tear up the entire interior to run 1 wire
