Thoughts on speakers / volume control?
Sasquatch!:
For my next cab, I want to mount speakers underneath the marquee. This cab will have a TV as its monitor. I'm teetering between two ways of doing it:
1. SPLICE OFF OF THE TV'S SPEAKERS
Open up the TV, find the speaker leads, and splice wires going up to the speakers in the cabinet.
Advantage: I'd be able to control the volume with the TV's remote control, so I wouldn't need to mount an external volume knob.
The questions: Will your average TV be able to power a second set of speakers? And will I be able to use "regular" speakers (like car speakers) for this?
2. USE AN AMP OR A SET OF AMPLIFIED PC SPEAKERS
Advantage: I can get some monster crankin' sound out of it - subwoofer and all if I want.
Considerations: I would still like to use use "regular" speakers. I don't care for the look of PC speakers with the volume knob poking out of one of the speakers mounted in the cabinet.
The questions: How would I be able to control the volume?? If I mount a knob somewhere, I have no idea how to get it to actually do the volume control.
Thanks, and stuff!

Sas-
I went with your option 2. I bought a set of PC speakers with an amp(btw $15 - $20). The amp had a bass and volume knob on it, not on the speakers. First off, I didn't use the speakers, I bought 2 "car" speakers to mount above my TV. I then took the audio out from the amp and split it to go to the TV in and to the speakers (this way the volume for both is controlled in one place). Then I opened up the amp and pulled out the little board that had the bass and volume knob shafts. I basically made an "extension" cable to extend this small board up threw the cab into the control panel. I just cut off the bass shaft after turning it all the way up (best sound that way) and then I drilled out the inside of the right side of my CP so that the shaft for the volume control would protrude enough to get ahold of. I mounted the small board there, securing with screws and covered with duct tape to protect it. For the shaft sticking out, I went to Radio Shack and bought a generic black knob and attached it. It works great, and you can reach it while playing for adjustment. It controls the speakers above the tv and thru the tv! Hope this makes sense...here's a photo, note it's not the white "pinball" button....http://community.webshots.com/r1/5/98/58/21259858AYrnKnKKWR_fs.jpg

JLR2000,
So you ripped out the little PCB that had the volume knob out of the amp? Hmmm. Provided that I can't extend the knob or find one that I like, is there any other way of doing this?
JLR2000:
Honestly, I was lucky enough for this to work the first time so I didn't research any other options. It really turned out to be a last minute enhancement....I figured I would have to open up the cab to adjust the volume but as the cab came together I decided to open the amp up to look around and viola....you have the rest of the info. I didn't really extend the knob, I just drilled out the inside of the CP so that the thickness was less. Could have done this with a router as well but the CP was already together. You should be able to extend the PCB though, only a couple(?) wires and this was my 1st soldering attempt! Good Luck.

BTW, here's the exact amp that I hacked...from the place I got it. I'm not a real audio freak, but I think the Amp sounds good, esp. for the price. http://www.pricepc.com/cgi-bin/sku.php?item=1510
