Great speakers that won't break the bank
Great speakers for the price can't go wrong with infinity they are built well and run at 3ohm so it won't damage your stock head unit and won't loos out on to much power from your stock head unit like you will with a 4ohm speaker most factory speakers are 2 ohm so these are a pretty good match and even have better bass. And crisper vocals.

Infinity never disappoints!!!
I put these in my C4 Corvette and they sound amazing compared to the 35+ year old Bose junk that was in there. Even when I paired them with a cheap Amazon radio they still sounded fantastic. 🤣 Infinity never disappoints !!!

Huge improvement over stock, well balanced sound
Beautiful sound quality from these speakers. A huge improvement over stock. This don't focus themselves around bass however they have a very respectable level of base. Where these shine for me is just the balance of low, mid and highs. If you value clarity and you're on a budget. This is a no brainer. I recommend. Great quality

Awesome Value For The Money
These are super high quality and a super bargain for the low price! They are capable of very low bass and even teamed up with my lacking Honda Accord 2005 factory radio deliver crazy good sound and are plenty loud! You might not need a subwoofer unless you really liked to be thumped. As some others commented they tend to be bright but any good equalizer should tame these to your exact preference. I have the treble turned down to -2 on the factory radio and the speaker treble button set to 0 dB (no treble boost) and I am quite happy with the sound. My only tiny quibble is that the tweeter and midrange bar are tilted inside of the speaker and the pictorial instructions don't give a clue for how to orient the speakers in the back deck of a sedan. I guessed that the mid-range/treble bar pointed towards the front of the car was the correct install.

Not an exact fit for a 2020 ram 1500
Not an exact fit for a 2020 ram 1500 night edition with a alpine speaker system. I'm going to expand the holes on the speaker and make it fit. The speakers sound amazing though and they are very well made. Absolutely worth the money, but keep in mind, you will have modify them to fit in a 2020 ram 1500

Stellar speakers!
Stellar. Replaced the stock Chinese 1/2 lb door speakers in my 2022 Ram 1500 Big Horn with these infinity reference and they crush the old ones. Amazing clarity, high & bottom end. Powerful & heavy.
