If your device doesn't list wattage, but it does list amps, then just multiply the amps times the voltage to get the watts. For example:
amps x volts = watts x .30 if you dont have any information you are sol.

It doesn't work.

Pyramid makes the PB series of amps. I have one that's driving a Sub.
The PB 700 puts out rms 60watts x 2 @ 2ohms, which gives you some "headroom" for your speakers. You don't want to over drive speakers with , for example, a 1000 watts for 100 watt speakers, because that's a good way to blow your speakers.
There are many brands and models of amps that will fit your speakers. Just make sure the amp will drive 2ohm speakers, since your jbl's are rated at 2ohm impedance.
You may want to consider adding a Sub woofer to your setup. A single Sub would fill in the low end very nicely. If you got a 4 channel amp, then two channels will drive your jbl's, and you can bridge the other two channels to drive the Sub. That would be a kick'n sound!
Just make sure the amp is bridgeable
For example, the Pyramid PB 1200 is a 4 channel, bridgeable amp. This particular amp will drive the 2ohm jbl's, but you would want a 4 or 8 ohm Sub connected to the bridged channels.

it is more than likely that your rca outputs are bad

if i keeps blowing fuses then it means the amp is bad

Hi! I saw your question, and maybe this will help. I also have a Texas Star 100w amp, and this same power supply. Even though the nominal draw for your equipment is way below the rated amp flow of the power supply, when you key up, and the output on the amp is at max, you are drawing the limit of your power supply! Try running this setup at a lower linear output. You don't need the full 100 watts to get out! 60-80 watts is aplenty! You should start at a low output, and slowly increase the output(while keyed up), untill the power supply starts to complain.(buzzer/light). This is what your limit will be. The only other cure, is a MUCH bigger power supply. Unfortunately, I cannot afford a 60-90 amp supply, so this is what I am forced to do to use the one we have. Also,keep your cb's output very low when using the linear amp. These amps are supposed to get a low signal from your radio, or the linear amp is overdriven. (noisy and unstable. Hope this helps you! 73's to you! jimsjinx
