How to fix your dead MSP subwoofer

[1sty]

what are you talking about no rear deck speakers?

i have 2 tweeters, 2 front door, 2 rear door, 2 rear deck, and the sub... (unless the rear deck grills are just ports for the sub?)

The grills are there becuase mazda would be retarded to make an entirely new rear deck lid for just the MSP.

The MSP has rear door speakers.

anyways. to those of you who's sub has "blown" maybe it is the voice coil... but it never hurts to check it out.

This is where a DMM earns its keep. It can basicly point you to the problem. getting an infanite resistance means you most likely have something disconnected. A very high or VERY low reisstance means that sub has gone to a better place. If you get like a 20 ohm resistance, it may be a crappy tinsel lead connection. It may just need to be resoldered.

yeah man... we determined that last night... another thing to point out how retarted i am w/ this stuff... i thought there were speakers under those grills on the rear deck...

anyways... im off to bed. will pop back into this tomorrow evening

Are you operational again?

 

[1sty]

well...i just tried this. started @ around 11:50PM and here i am now @ 12:58am. there was a wire disconnected. so i connected it and surprise ! still no bass...guess that means my sub got ****** in the ass coil...the thing that scared me the most tho was when i reconnected my battery terminals, my engine wouldn't turn over. everything was on, except the engine wouldn't start. i got so scared i thought i burned a fuse, but when i came back from checking this thread, it started...

Get a DMM and measure the resistance of the sub form its terminals.

DAMN ! If you cant feel it from the front ? IT AINT WORKIN !
Now y'all do know the you can hold down the AM button to turn the sub on & off ?

 

[jflo]

yeah...it's called the NF function

 

[SirJaime]

I hv never had to spend any more money on DMM , testers etc.etc. just the wirer , subs amps , stereo , maybe a few other little things and I hv been playing with systems from before they were systems 8 tracks and s***. And If your voice coil is fcked up your sub/speaker is fried , trash it

And I aint seen 1 speaker that will not blow if you put to much distortion in it . Good luck anyway !




NF kewl , never knew and the freakin dealer didnt either !:wtf:

The W3 or W0 will fit.
play the system and then go to the trunk and see if you can feel the sub moving.

Several things can cause what your getting.

The sub is moving, as I can see it reflexing while music is playing. I was installing the AUX input box and having a tough time with pulling the unit out. Seems that Mazda tied down the cables so you can't remove it.

we took our sub to mazda cause it was makin whatever weird sound it was all they did was change the amp and sub(cause its a unit) and they tell u its the sub as well but just give u a whole new amp and sub then send u out the door! i still had the problem i just decided to buy a different sub that fits in the same whole the sound went away.

It could be an RCA

1st MP3 in NH what would you recommend as a replacement for the stock Kenwood in the event of a meltdown? Taking the stock amp into consideration.

 

[Mspeedchica3.5]

oh yeah by the way has anyone put any foam or such in the back to keep the trunk from rattling.

 

[Notorious]

those holes for the 6x9's in the back deck are useless... they don't even work as a good port, i dynamatted the entire rear deck.

Same here. Sounds better now especially since i use 2 10s and ignore the 8 inch.

JL 8W3v2D2 if you correctly remount the amp. If not, then a JL 8W08

How does turning the amp over allow it put out more power? Is it due to heat disapation? There is a huge difference between 8ohms and 4 ohms as far as power goes. Or do you run the 8W3v2D2 as 1 ohm?

 

[1sty]

The stock sub is 8 ohms to aviod heat issues. The kenwood is stable at a 4 ohm total when bridged. Use the W3 as a 4 ohm load and flip the amp over to ensure proper heat disapation.

Can it breathe even if flipped since the heat well be trapped on top? Figures that they wouldn't install in a manor to get more power from the amp.

im operational again... was the same damn connection that came loose again

 

[solospeed]

I wish mine was as simple! It was blown.

 

[jflo]

mine's just a POS. i'm gonna check it out again and see if anything is wrong...mayn i wish i had that DMM right now so i could just check the resistance. but i want that damn JL 8w3v2d2
