Sub Noise

If you have any other preamp out sets on the head unit, try those. Otherwise...

Relocate the ground and make sure it touches bare metal as bberman said. If that doesn't work, disconnect the RCA leads from the amp side short the inputs (not the power leads) on the amp. You can just do that with speaker wire if you want, but don't let it touch any other places accidentally if you do...

If it still hums then it's either cables or the amp itself. You can try hooking the power up via a good set of jumper cables to see if the cables were bad, but beware, without some spare power wire that you can clip onto, the clips aren't going to go on the amp too easily...

If shorting it does work, check/replace the RCA cable. If that doesn't work, you could try an isolation transformer on the RCAs. If none of that works, I think your best bet would be to replace the head unit. Be careful if you have T-Tops though!

bberman: i relocated the ground cable, to the rear seat bolt i have a whole Monster amp wiring kit for the setup that's 8 gauge.

dragonrage: i only have one pair of preamp outs i relocated the ground to the rear seat bolt which obviously is connected to bare metal...i'm a little confused on your shoring the inputs statement however...do you mean short the inputs on the wire going directly to the Bazooka tube, or do you mean to short them from the head unit, because i have the Monster RCA going from the outs on the head unit connecting to another set of RCA wires that are about 1' long coming from the Bazooka tube, however, I shorted the ones going directly to the bazooka tube, not by the head unit, and there was no noise, is that good or bad?  Would I really have to replace the RCA cable?  I spent so much money on the one I have...

A side note, when i turned on the head unit the hum was really loud from the tube, I then went back to the trunk and moved around the wires a bit and it stopped, then i noticed that while i was playing a song or the radio the bass sounds really bad (like loud) sometimes, and sometimes it hits right.  I also notice that while changing tracks on a CD, that little pause between one track and the other where your not supposed to hear anything, i can vaugley hear some sub noise, (this is when i moved the wires around and the noise stopped), but i heard some noise during that changeover.  Just wanna let you guys know that my car is going to the body shop for the rest of the week so I won't be able to try your replies until next monday the 24th, thanks a lot for the help guys, sorry i wrote so much.

i'm still confused dragon, sorry, but there are no RCAs on the amp, there is a plug like the one pictured below, and from that plug are the wires to the RCAs.  Now what I did is on those RCAs pictured below, I used a wire to connect one of the RCAs to the other RCA touching the inside only, and that produced no noise...also realize that the amp and sub are one unit in the box, and the casing is plastic

I know that you don’t have the car right now. But you should not use the seat bolt as a ground. If you move the wires around and the noise stops then you know your problem is being caused by one of those wires. Make sure that the signal and power (includes remote wire) are all as far from each other as possible. Once you get it back play around with those wires and connections and I am sure you will locate the problem of the interference

I also notice that while changing tracks on a CD, that little pause between one track and the other where your not supposed to hear anything, i can vaugley hear some sub noise, (this is when i moved the wires around and the noise stopped), but i heard some noise during that changeover.

-what could that be?  is that all with the bad ground?

Also, what should I use as a good ground, I heard somewhere the seat bolt is the best...below is an older picture of it, now the wires are more tightier and they all have black plastic tubing around them, but notice the blue RCAs coming from the tube are going straight to the left side, while the ground is going to the other side, i don't know how much more i can seperate them.  also, ignore that ground loop filter in the back, that was my old setup and it did noting so i removed it.

sorry for the screwed up pic, don't know why it did it, here's the link to it
