i have a amp im selling to a board member, and i know it worked when it came out of the car, How can i test it without hooking it up to subs. He just wants me to verify that it works, which i can totally understand..
Any ideas?

i know it works thou

 

Iono, but my setups always had all the wires right at the same place, so it only took a minute to swap in another amp.

Are your wires still there??

 

well the amp came from a friends car, i bought the amp off him, but i went a different route with my system. He doesnt have the car anymore

 

Gotcha!

Good luck I guess.

 

a multimeter would work, but i don't know where to find one that would measure 300+ watts.

 

To test an amp with a multimiter, you switch it to AC volts, as audio is a form of AC.

Hook it up to a power and ground source, and a signal with a track of just bass tones. You can find test tones all over the 'net, or with a comp cd or bass mekanic, something along those lines. Fire it up and measure the volts.

It's hard to say what voltage you'll see as you have to have a fixed wattage to determine exactly what it should be. But if you just want to verify that it works, as long as you see some voltage.

I've measured my MTX81000D around 20 some odd volts at a decently low volume.

But, if you're going to go that far, you might as well hook up a speaker *shrug*

 

Hook a positive wire from your battery to the + and remote terminal and then hook a wire to the - terminal and find a good ground and see if the power light comes on. If you want to test it fully, get a stereo reciever with RCA outs and plug it into the inputs on the amp, then hook a speaker to each output and see if sound comes out.
