How can I tell if my amp is blown?

Is there anything other than my subs I can use to test my amp?

Not positive but I think you can use a volt meter, kinda like in the gain setting thing. But you have to have one of those waves playing on the stereo for it to read right.

Well I have a dmm not sure what the numbers mean but I can get em if that will help figure out if my amp is okay or not.

To be safe, try a 50 to 68 Hz test tone.

Actually the easiest way to tell is to substitute the subs for some "known good" subs/speakers.

Find someone with some subs/speakers that you know are working and hook them

up to your amp. Home audio speakers will work in a pinch.

You could also hook your subs up to a known good amp to rule them out as being blown.

Well I rewired one of my subs in series and took it by itself to see if it would even turn on.

So it worked on one channel, hear some bass coming out of it, but in the other channel it just ballooned out and stayed that way.

disconnect the speakers and burn a 50 to 65hz tone on a continous loop to a cd and play it while you measure ac voltage at the speaker teminals on the amp. make sure speakers are disconnected. post the results and amp specs and we can help with that info.

The channel that "ballooned out" has a blown output stage. That ballooning out is straight DC being fed into your speaker which is NOT good. If you reversed the wires, it would **** in. Do not leave that channel hooked up long or you could cook your speaker.

Yeah I turned the car off right away.

Do I need a new amp?

being that its an older model it would prolly cost more than it is worth.
