They are type r alpines what else needs to be said. They are well worth the money. I have 150watts rms going to these and I can turn them up until my ears hurt and they do not distort. It is unbelievable how loud and clear these speakers really are. The crossovers are very small and have three adjustments on them. The tweeters sound ds mnemonic good and the mids are perfect. I did not stop there, I also have a swr10d4 subwoofer in a custom made center console that is ported tuned @ 32 hertz powered by a hifonics brx1600.1d amp @ 2ohms delivering 1200 watts rms to this bad boy and it will take your breath away. I had my box sealed at first but just wasn't quite satisfied. Then I cut a 2" hole and put a price of pic in it 6 1/2" long and the volume and bass at least doubled. I could not beleive the difference. The cubic ft. of the box is 1.04 and that is subtracting .08 which is alpine specs. Buy alpine they kick ass

Using these with a pdx-4.100 that is tested at 121x4 RMS. I have these in the front and 5 1/4 coax in the rear and it is great. Perfect RMS on these and and the amp so it won't blow the speakers. The digital amps don't tax my electrical at all. A pdx-m6 and a swr-12223D for the rear. The whole car ( 09 Red RS6 xB ) is running at 4 ohms and the amps barely get warm. They play at mid volume for 4+ hours on the battery in the back yard while I do work and the car starts just fine. Kinetik 1800 battery and this setup is all ya need. No caps needed.

I've had 2 sets of these speakers (front and back) for awhile with an Alpine digital 5 channel amp and they sounded good but that amp and headunit were a headache. Swichted out the amp for the pdx F6 and the 900w head unit. The head unit helped because it was easier to tune but WOW if you have the right amp behind these speakers they are crystal clear!! I think Im going to purchase a pair of the SPX 17 Pros but I am nervous about it because these speakers are great and currently have no problems with them. 150 dollars for 4 speakers that can crank out clear sound at high volumes you will be hard pressed to find something better.
