Subaru Speaker Upgrade Kit by Kicker - H631SFJ001 - Genuine OEM

There are many reviews where people feel as if these aren’t that great compared to stock or introduce new issues with low ends and such. I’m going to try and be clear. The situation for my car 2015 Subaru Crosstrek Limited with Premium features but not actually limited - 6 speaker stock Subaru system, two tweeters, two front and two rear. I am an audiophile. I blew both rear speakers unintentionally and decided to give Subarus Kicker upgrade a try. I did plenty of research and I’ll be honest, I’ve never had my preferred level of luck with aftermarket other than overkill lows and sacrifice in good tuning of all High Mid and Low ranges. Since I don’t really have time to tinker, the Subaru drop in upgrade made sense. I didn’t get the Tweeter upgrade yet, but I will now. Dropped all speakers in, spending about an hour and 45 minutes. I reset my EQ, let the speakers play loudly for a bit to break them in and then started tweaking. Pros: - I didn’t experience any muddy areas that others talked about. High to low freqs were clean - The higher wattage opens up the factory system and the Sound Level feature is more noticeable and impactful. I typically don’t use it when I have my sound tuned but it’s better. - Zero distortion because likely the head unit can not push these hard enough but that allows pretty aggressive play in the EQ. - I hate drilling fresh holes so just dropping in is easy. - Already has dampening foam on the edges where it contacts with the door. Easy - Clarity is a no brainer from stock. If you don’t hear it, you may have a bad set, connection or head unit. - The LOW end is clear, clean and present. I was going to put this as a con because my car wasn’t shaking from the low end but this really is unattractive to me and I like clean, non-rattling cars. Cons - if you need instructions, you won’t get them. - I’m still not sure yet if the price is worth it but basically $50 a speaker. It honestly sounds better than any $100 speaker set I’ve had but yes, it may appear spendier than expected. TL:DR - It’s worth the upgrade for the ease, tuning and compatibility. People need to take their expectations and most people who talk audio, don’t understand it. As long as your head unit and connections are good and you don’t get a lemon, this is worth the upgrade, plenty of power, range and bright highs.

Super easy installation (plug and play). No additional connections needed to work. The quality of sound and material is great. Finally I can listen to music in my 2019 Sti. I have been using for a couple of months now with zero issues. Price was the lowest I found which was a big plus for me.

Perfect upgrade/replacement speakers. My front door speakers were blown so instead of adapting aftermarket speakers I decided to go with these. They drop in with no modifications and the sound quality exceeded my expectations. Nice crisp highs and mids. The low end bass is not amazing but it's good enough for me. Adjust your sound settings so the speakers don't distort at higher volume levels. If you do that, these speakers get plenty loud. Im very happy with them👍

This is a very good upgrade to the stock sound system with OEM compatibility making installation utterly simple (various install videos on YouTube, follow along step by step and truly anyone can do it). My one complaint is that the speakers are very apparently designed with the OEM Kicker subwoofer in mind and produce less bass than the stock system. While the sound is much improved, the bass output is less than what the stock speakers are capable of. The Kicker system is worth it, but I would strongly recommend you get a small subwoofer with it. I’ll probably have to add a hideaway sub to balance the sound properly. The reason this is mentionable to the average consumer who is not an audiophile is because these speakers, sold as a direct upgrade, absolutely output less bass than the stock speakers. This is not immediately knowable from any easily found information about this system, unless you dive in and read anecdotes on forums where it’s frequently mentioned. And importantly, I was satisfied with the level of bass from the stock speakers. The stock speakers with Bass EQ set to 1-2 is about equivalent to these Kicker speakers with the Bass EQ maxed out. It’s something that anyone purchasing these should consider or you may experience a degree of disappointment if you were trying to avoid adding a subwoofer (which is annoying and takes up valuable space).

Absolutely worth doing...and very easy. The stock speakers are crazy cheap and, if you have a base model Subaru, it doesn't even come with tweeters (although they are pre- wired). So, be sure to also get the tweeters as part of the upgrade. The overall difference in audio quality is well worth it.

2020 WRX OWNER- First off, I would say I was super excited about these speakers and they did sound amazing. I’ve been trying to upgrade my audio system slowly. I bought these speakers back in May. The front driver side door speaker blew two to three months after installation. After doing a bunch of research, I realized there wasn’t enough power from the stock head unit. I tried contacting the sellers since they do have a one year warranty and they SUCK at replying. I tried emailing 3 different people and I’ve only got an answer once from one of em. That’s what the one star is for. I wasted my money. Now I’m buying a whole new set of KICKER for the front door speakers. RESEARCH AND KNOW WHAT YOU’RE DOING BEFORE YOU WASTE YOUR MONEY!!

Easy install it

I just bought my 2017 WRX back in October last year, it still had its stock speakers, sounded decent, I knew it could be better. I later noticed the driver door speaker wasn’t working, but I could live with it for a bit until about 3 weeks ago the speakers started making static noises, basically ruining the listening experience (might be because I was pushing stock speakers with a idoing headunit). I then purchased these MARVELOUS KICKER SPEAKERS and TWEETERS!! Oh my goodness, my speakers have never been bussin like this before! I also have the Idoing headunit installed which can really push these speakers to their TRUE POTENTIAL. If you don’t have these speakers already, I highly recommend you invest in them. I fell in love with my car all over again, thank you kicker!

If you want a hassle free speakers upgrade for your WRX STi , this is the way to go. Perfect fit, easy to install and soooooo much better than the factory speakers. I pair them with Dasaita head unit, and for the first time i can properly liste music in my car.
