Help with StarSound components please....

Hi Guys and Girls,

So i recently started with some basic audio for my Opel and last week decided to fit a set of StarSound components upfront.

So anyways i wired up everything and than tested the components on normal power with the crossover connected to the headunit,everything works fine and i decide to now run it on my SoundStream lil wonder LW2.240 amplifier.

Connected the two amps (one for a sub) to a fused distribution block and than tested it out.

There was nothing coming from the speakers at all than decided to test the amp on a subwoofer everything works fine

Im not really a guru when it comes to sound but wanted to Diy everything on the car

Could someone shed some light on this issue please?

Am i missing something ?

Thanks in advance
