What are you using for your crossover? ------------- Support the12volt.com

Can you test the amp with other speakers to verify that it works?
Can you test the tweeters on another amp to verify that they work?

i dont have another amp to test the tweets but i do have other speakers, and they have a crossocer built into them

Do the other speakers work with the amp?
What about the amps' crossover? Is the crossover on the amp set to full range? ------------- 2013 Kia Rio -90a alternator

You say the crossovers came with the tweeters. what's the make/model? ------------- Support the12volt.com

Have you tried the other speakers on the amp yet?

can anyone tell me if that jvc amp will be compatable with these tweets or not?

Yep.

ANY amplifier is compatible with ANY driver, as long as the impedance of that driver is higher than the minimim allowed connected impedance of the amplifier.
If those are 4-ohm (nominal) tweeters, there should be NO issue running them with (pretty much literally) any amp manufactured since the early 60's.
You have issues elsewhere.

doodie. yeah theyre 8 ohms i believe il have to check on that though

There is no issue operating any 8-ohm speaker on any car audio amplifier. That is an easier load than 4-ohms. ------------- Support the12volt.com

That means that there's twice the chance that they'll work with the amp VS 4ohm tweeters -which most are. ------------- 2013 Kia Rio -90a alternator

well what im asking is wether or not the amplifier will reproduce the high enough frequencies for the tweets?

That will be determind by the frequency response capabilities of the amplifer. Is this amplifier, by chance, Class D? If it is, is it specified as a "subwoofer" amplifier? Please inform us of the MAKE and EXACT MODEL of the amplifier...
8-ohms will work. I promise you. There is something wrong somewhere, and we're trying to help you discover what the issue IS...
The difference between 8-ohms and 4-ohms, besides resistance, is 1: the amp will make half the RMS power - NOT an issue, EVEN REMOTELY with the efficiency of any decent tweeter connected to it. (Even if a woofer were connected, the difference in total output is less than 3dB, an inaudible difference.) 2: The amp will make less heat, i.e. half the current running through the transistors. 3: The amplifier will make one-half the distortion into an 8-ohm load as it does into a 4-ohm load.
These are all desirable, IMO, and if you'll help us with a little more information regarding your gear exactly, we'll be able to get further toward a solution for you.
