A: Yes, it's recommended to get a decent amplifier for these speakers. I learned the hard way, a stock radio with out much power could make these speakers sound distorted.
A: Ryan, you must find out what size speakers were originally installed in your vehicle. A six and a half inch speaker will not "fit" in a five and a half inch hole. The amp has nothing to do with this install.
Q: Can I put these in a GMC Sierra??
A: Yes , I have a 2013 GMC Sierra texas edition . I used the speaker Kit from Best Buy also. The speaker housing is loose if you just use the one factory screw , rattles when driving . I drilled a two small holes on the bottom side of the kit. “The holes are already there “ . The two screws to tighten the whole housing. Worked great
Q: Would these speakers be considered marine grade, so I can put them on the outside of my fifth wheel?
A: Not marine grade.
A: Yes. If you’re replacing all the speakers they are a great idea and u should get an amp to get the best rms watts out of them!
A: Unless you have a power amp attached you won't need any battery changes. I recently installed this set in a '10 Colorado, along with a set of 10" amped subwoofers... the woofers need the power boost, the speakers alone though should meet your desires alone.
A: According to available databases, the 2015 Honda Accord utilizes 6.5" speaker sizes in the front doors and rear deck. The KICKER CS 6.5" coaxial speaker is designed to fit this sized mounting location. There can always be unique situations where your vehicle is a special edition with possible different sized speaker locations or inaccurate information in fitment databases. Check with your local KICKER dealer for more information.
Q: Do these speakers fit on a 2012 toyota corolla S?
A: If your factory speakers are 6.5 they should fit. You might have to drill new holes to mount them in the factory hole, I had to do that for my 94 Ford F150. Sounds good.

Don’t know too much about car speakers, but after installation these are pretty nice as far as I can tell. I have a 2017 Kia Forte LX. Watched videos on YouTube showing how to install by disassembling the door panel, taking out the old speaker and rigging the old bracket so the new speaker can fit, but I skipped the rigging and just bought new brackets and harnesses from Crutchfield. Got one new speaker in and compared it to the old speaker on the other side using the radio balance, and the new Kicker is definitely better. Much more clear and just a bit louder, since I don’t have an amp yet to boost it to full potential. Unfortunately, I broke a couple of the door clips and also the handle mechanism allowing me to open my door from the inside. *sad emoji*. Just be careful if installing yourself.

Very easy install with a harness and speaker adapter to fit my door speakers in my Acura RSX. Note: 6.5” will not fit the rear speakers, used 5 1/4” for the rear, also with a speaker adapter and harness. Both sizes of this speaker produce a very high quality sound. Perfect addition to an aftermarket head unit. Best bang for your buck to upgrading your stock speakers.
