Unsure if I just screwed my sub or not?

Okay, so I was testing out a broken amp that some guy gave to me on cragislist, and when I plugged it into my sub, it just made a popping sound, and the suspension lifted & it just stayed that way.

Then when I tried it with my working amp, it didn't have any reaction at all, then I tried putting it on the "broken" amp, and the suspension stayed up.

Whats happening? lol. I'm thinking maybe it didn't work with my working amp because it only has specs for 4 ohms, & I was running the sub at six.

I figured maybe the amp would be able to keep up.

The guy told me it just simply didn't turn on, so I figured it wouldn't do anything bad? lol.

do you have a DMM? is the sub 'stuck'? if it is, then //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

After I unhooked it, it went straight back down. Is this a good sign?

The amp is fuxered, it's outputting DC current and not AC. Your sub should be fine.

Thanks buck ^ Would it be easy to fix an amp like that?

If you are asking that question then perhaps sending it someone who is a reputable amplifier repairman is the best option for you.

No, I think not.

sounds like a common issue you see on rockfords. unless you plan on getting into fixing amps, i would suggest having someone repair it for you. there a guy who KNOWS HIS ****, @ diyaudio.com. im not giving you his name etc, but i will give you his website and you can email him from their about your amp. he is very reasonable on pricing, and hes trustworthy.

also this is directly from his site"If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor."

Basic Car Audio Electronics

this site is also VERY helpful if you decide to work on it yourself. if it is a shorted output transistor, the repair is not to difficult, just need to know how to use a DMM and have a decent soldering iron.
