Using car speakers in a cab
Silverwind:
Hello,
I have a polk audio component set I would like to use with my cab if possible. They already have grilles and everything so should work well.. I was going to plop them in my car.. but have changed my mind for the moment ;)
it is a pair of 6 1/2" woofers with 3/4" tweeters.. with crossovers
What is the most cost effective way to power these? Preferably I would like a 25-50w per channel amplifier to make decent use of these speakers..
Where/What to get to power these? I want to try and stay away from a car amp if possible.. whatever is the cheapest/best value however..
It has to be able to support 4ohm stereo as the speakers are 4ohm... yes I could wire them series but then i'd lose stereo capability ;)
Any ideas?

You *could* use a normal, cheap, 8 ohm home stereo amp to drive those. Yeah, it'll probably go bad at some point, but just be careful not to turn it up too far.
I'm sure many people will tell you not to do this and give you good reasons for it, but you're not supposed to speed either.
You could find a home amp that drives into 4 ohms, but they are usually the higher quality and more expesive ones.
Check Ebay, some of those "glorified boomboxes" that have a radio, cd, and tape and detachable speakers drive at 4 ohms. Sellers like Realcrazymo salvage that stuff and resell it, you might jsut find what your are looking for.
Then again, you could get a used car and and 12v 10amp power supply for ~$100 on ebay as well, and not worry about the other stuff.

I used a two car audio amplifiers and a couple extra CPU powersupplies and a case I had lying about. 40w/channel is more than you want to stand directly in front of. :)

hmm that's a good idea.. does it work pretty well?? Do you use the +12v and ground of the PSU?(+12v is about the same as a car with engine off)
you have two amps.. so I suppose you run one off each PSU...
heh I like the speaker terminals instead of the expansion slot brackets :P

Just be sure and shield the monitor/TV from the speaker magnets, or mount them far enough away. They'll wreak havoc on the display if you don't. I found that out the hard way and had to change plans midstream.
