Alpine S2-S65C - Next-Generation S-Series 6.5" Component Speaker Set

I was a little upset when I got these because they were open box and it didn't say anything about it in the description but everything was still wrapped and never used. For $120 it's a great deal. They sell for $180 everywhere else. In my 2009 Accord they work perfect. I have a 5 channel amp the pushes 75w to 4 channels @ 4ohms and 500w for a sub @ 2 ohms and guys it's so loud I can't get past 3/4 volume while I am inside the car, at that volume I am well over 125 db. The best part is at 1/4 volume it sounds amazing. So clear on the highs and plenty of midbase from the 6.5's. The amp is a Stinger MT 1000.5, a Kicker TRTP downfiring sub w/passive radiator and the rear deck has a set of Skar FSX 65 loud speakers with a range of 100hz to 8,000hz. A bit more control over the teeters would be nice but I am not going to get a dsp because most of it can be handled by the factory head unit and amp adjustments. Obviously there are better speakers for a ton more $ but none that can give you this sound for this price. Easy to install and great Alpine quality. I love them. Guys...get an amp. Even 50w a corner will make a huge difference in sound, 75w is perfect.

We used this to replace my bf’s speakers as they were broken. We used chatgpt to figure out how to do it as we were clueless lol thankfully everything went fine Overall these speakers actually play great and loud. Durability wise, im not too sure? But ive heard great things about the Alpine brand. Plus we registered our device online as they offer warranty. So we felt content with that. Ill update if anything happens, we’ve only had them on his car for about a month now and its still playing wonderfully.

sounds absolutely cinema, using an amp (Recoil DI550.4 in my case) and good amp wiring kits brings the most out of the speakers. Sound quality is amazing, really sketches & details the photo, mid-bass is great, can really feel it thru the steering wheel & paints the picture, but you still have to get a sub to frame the painting (Hamr is for midbass, low sub freq will hurt any door speakers). great option to upgrade any stock audio system.

Sound great, installed temporarily without an amp they were pretty quiet and flat (as to be expected, most stock audio systems call for 2ohm speakers with a much higher sensitivity as they are often paper cone). Once you pair them with an amp you’ll really hear the difference, in my opinion it’s not worth replacing your stock speakers (with these at least) without adding an amp of some sort - a lot of wasted value left on the table! Ended up with two of these in the front and two of the coax models from the same S2 lineup in the rear; everything is running off of a Hertz HCP 4D 4 channel amplifier outputting 75W RMS (<1% THD) up to 85W RMS (10% THD) per channel at 4 Ohms. Seems to be the sweet spot for the 80W RMS these speakers are rated for. Running off my stock head unit as it’s heavily integrated with a bunch of the vehicles features. Sound amazing with the Hertz amp, tested with a Pioneer A6704 amp before I switched to the Hertz as I wasn’t satisfied with the volume or sound. The tweeters aren’t too sharp and put out more detailed + cleaner sound than expected from a midrange speaker (keep in mind, it’s all personal reference). Still sound good at high volumes, nice for when you want to listen to your music with the windows down on a highway or something. I previously owned a set of JBL GTO609C’s and I prefer these Alpines mainly due to the higher frequency detail they put out. The JBL’s are for you if you want a slightly more bass heavy sound and don’t want/can’t have a separate subwoofer. The Alpine’s are definitely a little more “sparkly” compared to the Jbl’s “warmer” sound. I’m running two 12” SQ-oriented subs crossed over with these so my main focus was clear and precise mids and highs with some decent punch when needed, wasn’t really worried about the low end. Overall i’m very happy with these speakers, after a week of listening and adjusting things i’m satisfied with the sound and quality of these speakers, I do wish they came with an active crossover for the tweeters instead of a passive one but in the end I don’t feel the need to change them so it’s all good in my books! If you can get them on sale go for it, I doubt you’ll regret getting them especially when compared to some of the other notable mid range speakers in the market right now.

Alpine always puts out super quality products
