Infinity speakers

I was looking to upgrade my door speakers because one is on its last leg.

I was looking at infinity reference speakers and have a couple of questions.

First they say they rms at 60 but my head unit says it holds 50 will it still work?

And second it says it fits 6.5 but i seen that we need 6.75 do i need a adaptor i believe crutchfield says it fits so i am a little confused

not sure on the brand or fitment, but power should be fine, my head unit only put out 50x4 and i am running alpine type r components in all 4 doors. the alpine speakers have an rms rating of 110w per speaker.
They'll fit without an adapter just use the top mount holes. I got the same ones for my little doors (ext. cab). They aren't perfectly centered vertically so if you are a perfectionist then you may want to get an adapter. If you're cheap like me and emphasize function over fit, well... they'll stay where ya screw em.
Thank you both how do they sound in your truck Johnny
Crisp and clear. They pick up the mids really well. My set came with the 1.75 dome tweeters which I mounted above the A pillar in the headliner. Crossovers are tucked in the doors but they'll have to be relocated when I install my power windows. Overall I really dig them plus you get a cool Infinity sticker and who doesn't love stickers?
Speakers are a personal choice. You should go listen to them at a store.

With stock power it will be lacking clarity and bass. Your HU does not HOLD 50RMS. It provided a maximum of 50 watts. However, you'll lucky to see that. RMS numbers are all you need to look at. If your HU supplies 12w or 14w RMS and the speakers are asking for 60w RMS, you are not even close to providing enough power.

FYI: you are likely to lose most bass that your factory speakers provide. The speaker is designed for your truck and require like 5w to power. You'll have some bass of course, but it will not be the same. Biggest complain with speaker installation.

I had my Kenwood deck (similar power rated) powering similar rated speakers. It sounded okay, but when I put 45w RMS power to them, they cleaned up a lot and there is a more full and rich sound.

You are going to need adaptors for the openings. It's a pain but possible. The hole is closer to 7" diameter so the mounting holes for most speakers don't match up to the metal. An adaptor is screwed to the door and the speaker screws to the adapator.

My polk speakers came with adaptors, and they work better than the Crutchfield supplied adaptors.

Highly recommend an Alpine Power pack because my setup sounded "ok" until I put the power pack in and a lot of the distortion at high volumes went away and made them more clear and defined.

Is that the mini behind the dash amp? 45x4?
reference 6.5 will fit perfectly fine! no adapter needed ! i have the shallow mounts in all 4 doors. non amplified but sound is phenomenal ... crisp and clean . also have them in our boat components amp'd on a jl audio jx360 4channel amp couldnt get a better deal than that package honestly.
they are the bomb

Good to know. That's 2 that I know of that are a direct fit. Kicker are the other ones that drop in the hole no problem.
I have a set of 6.5's that are the 6.0c refs that have about 130 watts going through each speaker. Really helps a bunch with mid bass and fuller sound. You start to feel the snare. Crossed em at 80 hz.

Infinity reference are my first choice in automotive speakers, and the bass will be better, and much more defined than the stock speakers. I had Inf. reference in my 06 truck for 5 years. I loved them.
No one ever says high power speakers on low power decks have better bass. haha Neither my Sound Ordnance or Polk produced the same level of bass as stock. ha!

Speaker sound is personal choice....everybody hears things differently. I've owned Kicker. Polk. Infinity. Sony. Sound Ordnance. They all do something different and play different types of music differently.

The OP should take the time to shop around and audition different brands for himself. Most likely he could ask the same question for any brand and get the same answer ("these are the best") and he'd be equally pleased with his purchase no matter what he purchased.

When I had Infinity in the past, they were way too bright for my taste.

That's nonsense. The bass output of a particular speaker has nothing to do with it's ability to handle more power. A better quality, better sounding speaker is just that, regardless of it's power rating.
Come on man, I didn't discredit your post. Why discredit mine.....
Telling me my comment is nonsense.
i have been around and listened to speakers but in my area all i really have is walmart and best buy which best buy is expensive.

What's your budget for a pair?

What I would do is get an alpine power pack and a pair of components that take advantage of the 90 watts rms per channel in 2 channel mode. That's a good easy budget and the amp can stay behind the deck and out of the way.

Pick up a set of 6.09C's or you can run alpine type 's for alittle cheaper but they are an upgrade for sure. Then fiddle with the crossover setting on the power pack to determine how loud you want to go and not distort.

For about $150 I upgraded to Rockford punch 1675 and 1675s. I have a pioneer fhx700bt with 15 rms each channel and its decent loud. Good mids and highs not too much bass, it's there but I don't have them amped. Rockford has them as a high end factory upgrade handling 60rms.

I got them in 6.75 knowing they wouldnt fit but mounted them to the panel. I think the 6.5 fit in stock location. They come with an integrated crossover so you don't have to mount a separate box. I have hpf and lpf filters on my HU and didn't mind not have separate crossovers.

By no means am I an expert but depending in how serious and loud you want to get, these were ten times better than stock good quality and affordable. Once amped they will be good all around
