IF u like it loud and clear BUY THEESE SPEAKERS
I installed these in the rear deck and the front doors of my car. Had to put adapters in front doors so windows will go down. I'm running 135 rms from a pioneer 4 channel amp. And these speakers get really, really loud. I am impressed how loud they get without distorting, spend the 2 hun n get theese u will not be disappointed. They come to life with 100 watts rms on them. N they sound great.

Not recommended for 2017 impala front door panels install.
I've purchased these for my 2017 impala. They sound clean crisp and full and deep for their size. (I've purchased the 2" mid) the only thing I find wrong is the size of the 6x9 woofer in the doors. I've installed these in the stock doors and I thought if he burned these out with the stock amp bc they have started to sound raspy. I pulled one out and the rubber surround was torn from rubbing on the top door panel. Not recommend for 2017 impala front door panels install. Rear deck should be fine.

Covered under warranty
Update: Contacted Harmon regarding Tweeter failure. Under warranty they sent me out a new pair of tweeters free of charge.

Hearing stuff I've never heard before
After adjusting eq, sound is great. I just ordered the mids as without them there is a void left that sounds weird being filled by my rear speakers (have these up front).Pros: GREAT sound quality. All parts needed for installation are included Several mounting options for tweeters Very high quality constructionCons: Tweeter leads are pretty short No patterns for drilling any holes

Great sound
Great sound. Make sure to order the hardware for your vehicle. Otherwise you’ll be fabricating mounting brackets and wiring.
