## Description

Infinity 6x9 car speakers

Review: 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.

### ⭐⭐⭐⭐⭐ Awesome Value For The Money
*by D***V on February 12, 2025*

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.
