Question: Do I need an amplifier for these speaker?
Document: I wanted the best speaker set that a budget can buy, and avoid the costs of having someone install them for me. These speakers, research and all, paid off. No, I do not have an amplifier, but I really don't want to blow out my eardrums or scare the old lady crossing the street. These take away the pain of having a vehicle that's cabin noise isn't above 3 stars, and nerfs the effects almost entirely, and a great combination to have.
Bought to upgrade stock speakers in my 2010 Element LX. They sound awesome and I'm glad I bought these. I need to massage the speaker grill covers more as the front covers aren't as flush as I want them to be.
I installed this in my 2010 Jeep Wrangler Unlimited sound bar. You can tell right away that the quality of these speakers are way better than the factory ones. You will need the Scosche SAC-656 speaker kit to install these. You will have to drill a hole in the longer tab for them to fit. Took me about 2 hours to come to that conclusion.
I have a 1999 Saturn SL2 and their factory speakers were awful. I needed to get a new pair of speakers and after reading the review on these speakers, I decided to buy them. (Saturn SL-Series beware! You will need car speaker adapters to put these speakers in. The factory speakers are 6.75 inch which they do not mention.) After many hours of trying to figure out how to put these speakers in, they sounded great!
I ordered these as replacements for the rear speakers in my Honda element. They fit perfect and sound awesome they really come alive when you add an external amplifier.
Installed them in my daughter's Hyundai Elantra. Did need to purchase mounting adapters. Speakers sound great. Awesome high end, bass is adequate. Would have given 5 stars if them came with speaker wire and connectors.
You don't have to remove the entire rear panel. The only modification that you need to do is to use a scissor & cut/trim the extruding ring of inside face the factory grill cover (which sit on top of the speaker when you close the grill). After you do that it should snap back in place perfectly.Remember to disconnect the original speaker plug and you the speaker Harness to connect it back to the new Speaker terminals.
Needed new door speakers in my Chevy 1500 Silverado truck. These speakers sound great hooked up to my Kenwood head unit (cd player) without an amplifier! For the price, I would highly recommend these speakers!
Awesone speakers. Bass is not too deep, but you can be proud of it if you're not crazy about deep bass. Feed them with a good amplifier and use a crossover to send them the right sound.I bought 6 of these speakers ( 4 my wife's car, and two in mine).
Installed these in the doors of a Honda Del Sol and they sound great. Huge upgrade for the system. I do have them hooked to an amplifier, so obviously that makes the sound quality much better, so I can't comment on how they would sound just hooked directly to the receiver.
Answer: It depends on what your music source is. Most radios or players should have enough power to run these speakers. If you're using a car radio that will be adequate.
