Great product for the money.

The speakers sound great in my boat, they also match the seat inserts so they look nice as well. Always had great luck with Infinity.

Great Sound

I bought these speakers after hearing them on my friend's boat and paired them with a Kenwood digital medial receiver. I was looking to replace an older Sony system. They sound great. I would recommend the speakers to anyone looking to upgrade the sound quality of their system.

Infinity Marine 612 Speakers

Just finished putting 2 pair of the 612s in my Crownline 270 BR. Great sound, plenty of bass!! Great looks, Looks like they are well designed. I appreciate the technical help I had matching up the speakers with my Sony Receiver, 800 watt power amp and 300 watt powered subwoofer. The sound is amazing. Can't wait till summer.

These are very loud and perfectly clear at loud volumes. I have them in a 17 ft boat hooked to 55 watt rms amp, they are clear/ loud and perfect for noisy environments, highly recommended, along with sonic electronix this is my 3rd or 4 th order and every time I am pleased, thank you!!!

Much Better

My original Clarion marine speakers had rotted out in a short amount of time. I chose the 612M because of Infinity reputation and the look. For a small increase in purchase price over the Clarions I was shocked after installation of how much better they sounded and they look great. I get many compliments on the look. I would recommend these speakers for sure.

made it 1 year

Loved the looks of these speakers. We run them off a 600w amp. The first year and into the 2nd year they sounded GREAT but the wife loves stereo wars and 1/2 way through last summer the first speaker went and by the end of summer the other 3 gave up. I don't think any speaker could have held up and most would have been gone the first year. I'm looking at there 6*9 to replace these and adding 4 more of the 612M and a sub.
So yes I'm buying these again.

Rock The Water!

I installed four of these speakers in my 22' deck boat. They are close to the floor because that is really the only place for them on my boat and they still sound great! I bought the sony 600w marine amp to get their full potential. I am beyond satisfied with these speakers! They are LOUD w/ a great sound quality. These speakers really pound and look great. GREAT CHOICE!!

great speakers

Just finished putting a pair of the 612s in my deckboat. I also installed a pair of the 6912s. Great sound, plenty of bass!! Great looks, Looks like they are well designed. Have a sony receiver that they are hooked up to. Thought I might need a amp, but after hearing them, I think they are fine. 52 watts is fine for me!!! Sonic was very easy to order from. Good prices, and service was fantastic! Will be using Sonic for all my stereo needs. Can't wait till spring. Hope you hear me out there!!

Not impressed..

I installed 4 of these 3 days ago, powered from a Kenwood KMR-550 into an Infinity 5761a amp. Sound was ok at low volume levels but quickly turned harsh when cranking it up just before it turned into full blown distortion.
I have owned several sets of Infinity speakers in multiple applications and have never had any that sounded like these. I have pulled them out and I am going to try some Kenwoods.

great speakers

I bought these for my 232 sunesta deck boat. What a great speaker and what a HUGE upgrade. Replaced factory JBL. Should have done it years ago we are now rocking the lake with some real tunes.

They Suck

Purchased 4 of these to replace blown factory speakers. Have 320 amp 4 Channel JL amps powering them. Rated at 60 watts per channel.

Speakers cannot handle any pressure at all. Have lows turned completely out of them and they still break apart with half volume. Sonic is great to purchase from, but the Infinitys are a major bust. For the money, Im going back with JLs.

Infinity 612m on my 27 foot maxum boat

These speakers are very nice however i feel they dont have alot of bass. Have to get a sub amd amp . My original clarions have more bass than these. Otherwise sound pretty good for the price.
