GEN-X Full-Range Class D 4-Channel Amplifier 4 x 150 Watts Rms @ 4-ohm

I love these 4 inch tweeters

I love them they sound great along with the looks I have to say that I don't agree with the filters that they come with I feel that they do distort a little bit and so I gotten the 4.7uf 100v and that cleaned them up Alot on clarity the ones that come with these tweeters are 4.7 UF 250v if you change them to the ones I have you won't be disappointed these tweeters perform beautiful highs I have the paired with my pro x 6.5 witch I'm planning to get another pair of the mids in future !

4" Super Bullet Tweeter 250 Watts 1.5" Titanium 4-Ohm Vc with RGB LED Lights

Oh yeah.

There was a break-in time, maybe 15 minutes, but after that they have sounded great, a nice clear bottom to the sound.
