Found a little article on thermal compounds... learnt some stuff here..

http://compreviews.about.com/cs/cooling/a/aaTCompounds.htm

And a nice list of more thermal tape ...3m stuff...might find some of this locally..

3M™ Thermally Conductive Acrylic Soft Tape 9889FR 3M™ Thermally Conductive Acrylic Soft Tape 9889FR is a flame retardant specialty tape used for very large panels or surfaces where a very conformable thermal tape is needed to achieve good wet-out adhesion.

3M™ Thermally Conductive Adhesive Transfer Tape 8805 3M's highest mechanical strength thermally conductive tape, also offering improved surface wetout and excellent shock performance. 5 mils thick, 5.8 N/cm peel strength.

3M™ Thermally Conductive Adhesive Transfer Tape 8810 3M's highest mechanical strength thermally conductive tape, also offering improved surface wetout and excellent shock performance. 10 mils thick, 8.3 N/cm peel strength.

3M™ Thermally Conductive Adhesive Transfer Tape 8815 3M's highest mechanical strength thermally conductive tape, also offering improved surface wetout and excellent shock performance. 15 mils thick, 8.3 N/cm peel strength.

3M™ Thermally Conductive Adhesive Transfer Tape 8820 3M's highest mechanical strength thermally conductive tape, also offering improved surface wetout and excellent shock performance. 20 mils thick, 8.3 N/cm peel strength.

3M™ Thermally Conductive Adhesive Transfer Tape 9882 2.0 mil (0.05 mm) thermally conductive adhesive transfer tape for mounting flexible heating foils, temperature indicating films and thermoelectric cooling modules, as well as bonding flexible circuits to heat sinks.

3M™ Thermally Conductive Adhesive Transfer Tape 9885 5.0 mil (0.13 mm) thermally conductive adhesive transfer tape for mounting thermoelectric cooling modules, bonding flexible circuits to heat sinks, bonding heat sinks to microprocessors and bonding TAB-mounted IC to PCB.

3M™ Thermally Conductive Adhesive Transfer Tape 9890 10.0 mil (0.25 mm) thermally conductive adhesive transfer tape for mounting thermoelectric cooling modules, bonding heat sinks to microprocessors, bonding TAB-mounted IC and power transistor to PCB, and power transistor to heat sink.

3M™ Thermally Conductive Adhesive Transfer Tape TM-670SA 0.25 mm thermally conductive adhesive transfer tape with differential adhesion on liner side vs. non-liner side. UL94 V-2 rating. For heat management of electronic devices providing heat dissipation and bonding/joining.

3M™ Thermally Conductive Adhesive Transfer Tape TM-671SA 0.375 mm thermally conductive adhesive transfer tape with differential adhesion on liner side vs. non-liner side. UL94 V-2 rating. For heat management of electronic devices providing heat dissipation and bonding/joining.

3M™ Thermally Conductive Double Coated Adhesive Transfer Tape 8805KT

3M™ Thermally Conductive Double Coated Adhesive TransferTape 8805KT is a dual liner, 11 mil thick tape that uses polyimide film as a carrier. The polyimide film provides very high dielectric strength that may be required in certain applications.

3M™ Thermally Conductive Heat ing Tape 9876 3M™ Thermally Conductive Heat ing Tape 9876 is designed to provide excellent heat ing performance on plane direction to reduce the skin temperature of devices.


I have no clue what one would fit my application best..need to get some soon though..

Wow, good research. I would get whatever you can find. Your application is simple and doesn't require anything exotic, like what might be required on a really high voltage motor drive. Check Active Electronics, they have a store in most major cities. Online you could try Newark Electronics, Digi-key, and Mouser. I got a 4x6 inch sheet a few years ago by asking a manufacturer for a sample.

Yeah, there's some serious sounding tape in that list.. From what I gather, please correct me if I'm wrong. I need a very thin tape with good heat dissapation. Its the paste that will do the real work.

lol...I wonder if I could get enough by asking different companies for samples of different tapes...good tip!!

Thanks for the store tips Kev, now that I know there sooo many types, if I can't find some local, even here in nowhereville, I'm not looking hard enough..

Gonna try to work out the rca's wiring tomorrow when I find time... I also rethought that DSP you showed me. Sure would make running all the channels from 5 rca's easier !!and actual add some digital processing in the mix!!! Dang you!!

I'll do up a wiring diagram for how I would run the rca's, and run it past you all here.

Since my wire diagrams show nothing and make no sense..lol.. Though I'd just post pics..

Here's the basic idea with the rca's and xovers..this is the part I know I want as of now.

-First two pics are how the stock rcas plug into the board.. 4 pins

-third pic is of the rca wire, Stinger shielded twisted directional..I figure I need to use something with some shielding?

the pics

- fourth pic -- the rca ends at the amps and the outside of the box will be soldered, not plugged in. I'm having some problems figuring this out however, 6 small wires, 4 posts on one end, 4 plugins on the other?? Would the common RCA ground just go with the reg. ground, or would I need to ground it in a different place?? A little confused on this.( its not the rca wire in the pic, just for showing what I mean..shrug

-fifth pic is how the rca's will split off and how the xover will be added. Using splitters and fmods..There will be a opening panel with the xtra fmods held there, to be able to change the xover points easily. Here's what an fmod is if you don't know.. http://www.hlabs.com/technical/crossovers/

I think I have it figured out, except what to do with the extra common grounds..

Does this sound do-able while not causing any signal interference?

Also have these to use on the outside if it makes any difference..they each have 7 "plugs".. one must be common ground?

Dukk

Audio ground may indeed be common.

Honestly, I would avoid FMods if at all possible.

Thank Dukk. problem solved.. Have you used fmods? I still haven't even tried them yet, just assumed they'd be "ok"
`Should probably look into those DSP's more, those fmods are $25 a pair, might not cost much more to get a DSP board instead.. Just worried about my abilities with wiring it..

Kev- Could you explain the 2x8 minidsp to me a bit more? How does it get set-up to acheive the xover points? computer? wiring ? jumpers?
