All my reviews are about products i have found that have amazing quality for the price. This definitely falls into that category. I had these in my older focus hatchback. I had an aftermarket pioneer head unit giving them 22rms and it seems like just enough to make these sparkle. I always go with silk dome tweeters because i find they give a more smooth and pleasant sound especially since i listen to music with a great deal of screeching sounds. Everyone was impressed with how "magical" they could sound with certain song elements. never tried them with an amp but i assume they are even better. Infinity is my favorite speaker company.

Pretty solid product but they struggle when not amped. The mids are pretty decent but the highs are pretty harsh with rock. Once amped, they really come alive and the mids sound much better. I installed these for a friend and amped them with an Alpine MRPT220 and it sounds pretty nice.

Customer Testimonial

I was looking around for the best prices for car receivers. So I bought a receiver from Sonic Electronix that came with everything needed to install it, and I was able to install it in less than an hour! If I ever have any more car audio needs, SonicElectronix is sure to be the #1 choice on my list!
