hmm.. rear seatbelt bolts? i took out my rear seat yesterday. you mean the bolt at the bottom of the rear seatbelt should be pretty good as a ground?

i will try grounding it there. thanks!

 

here is a pic of my little mini sub tube. still have full use of my boot space too

 

Swooshmac, sorry to hear you are having problems. Here is what I would do if I were you. First make sure the system is working fine with your harness and without the sub. Are you getting good sound and does the balance work correctly, and the do you get all the sound to the rears when fader set all the way on the front speakers, etc.

Once you are convinced that is all working fine then start from scratch with your sub. Get a cig type plug from Radioshack or whatever your local equivelent is. It should have the male cig plug on one end and just pos and neg wires one the other end with a fuse in the plug. Hook the positive wire of the plug to the positive power of the sub and the negative to the negative. Then take a 2 inch piece of wire (use a piece you cut off the end of cig plug if you want since it is decent gauge) and put one end in the sub pos power and the other to the remote power or whatever they call it. You could also run this straight from the 12 V battery wire or from the cig adaptor but that is just adding the chance of getting a short (which is what it sounds like you might have).

As far as speaker ground, I was using the high level inputs and the chassis for the speaker ground but wasn't getting volume so changed the speaker ground (not right or left negative wire and not power ground but the 5th wire in the high level speaker input connector) and ran this ground to the power ground going directly into the sub and it works perfectly.

Let me know if this makes sense and if you have any luck with it.

One last thing, the main hassel of using the cig plug as opposed to taping the wires directly on the back of the cig plug is that the female part of the plug is not fixed well at all into the car interior wall so it often gets pushed through when you plug it in then its a hassel to fix it.

Kevin and Robin...thanks for all the help again.

kevin..i did what you suggested. all is good. but here is the strange thing and i hope you or someone else can answer this for me.

the humming has almost become non existant. sometimes it is there. all sound is hooked up correctly from X9331..fading works like it is supposed to and all is good. thump thump. BUT...while i was finishing...my ground accidentally came off the chassis. AND the sub still works!! is that normal?? Why is that possible? I have a amplifed tube and not the Boss600 (as i could not get it here)...and for some odd reason it works without the ground. that is not normal and i cannot figure it out. am i causing it some problems to my system if i do not ground the sub? but it all works! only thing i can think of is that since i'm running the RCA through the tapped speaker wires...could it be that the sub is using the hifi ground? i am just lost about why it works. any help would be very much appreciated, as i don't want any electrical problems. THANKS

 

Is the hum there with your X9331 connector in place, but the sub disconnected?

Sounds like the RCA and power ground are connected. You could test it with an ohm meter. Disconnect the sub from everything and see if you get zero resistance between the RCA ground and the power ground.

 

No humming sound if i disconnect the sub. X9331 connector has been working like a charm since i did it a month or 2 ago.

ahh.. i never thought about it like that. so it is possible that the RCA and power ground are connected? is that possible in some active subs? When you say 'zero resistance' .. what do you mean by that?

 

no access to an ohm meter . But if it is the case that the sub works...and the humming is almost gone now...then the RCA and power ground are connected.. assuming all this... then it is ok not to have a ground connected to the sub.. correct?

 

The ground through the RCA is probably not adequate for the power. You need to add a ground wire.

 

ok.. well then i have to find a t wrench to get the rear seatbelt bolt undone as i will try attaching the ground wire there. thanks again for all the help.

those using the low-inputs with RCA's do you still have the high input clip plugged in and grounded? (without the speaker connections?) or did you just take the clip out?

I lost sound a few months ago....figured it was the high level inputs that some also said wasn't working for them....bought this to fix the supposed issue: http://www.crutchfield.com/S-12Rey8X...ab=other_items

thought it would work but I still do not have sound. Actually strangely yesterday with the RCA's plugged in and high level input clip out of the boss unit, I lost complete sound in the car to all speakers until I turned the car off and back on again.....

I just figured one of the connections on the RCA's was bad and somehow "shorting out" briefly to shut the amp down.....

Suggestions?

 

Just want to give this thread a little bump so new mini owners know about the great upgrade that this sub gives to the mini audio system.

By far it has been the easiest, cheapest, audio upgrade available

 

No complains here! Tho the wife does. i used the hi-levels tapped from hi-fi amp's outputs

 

Have to agree! The Best/easiest audio mod out there!
