In general, most will say that it's highly recommended to power a component system with an aftermarket amp.

As long as they fit in the factory location no you wouldn't. If you're car has a premium stereo from factory you might be fine. But generally running an amp is the best way to go to get maximum sound out of a speaker. Underpowered speakers are just as detrimental as over powering. I have my dash to the radio then 2 sets of these 2nd set replacing my 6x9s and a p1 10 all mated to a 600.5 rockford prime amp. If you like to go that route rockford makes adaptor plates for these to be down sized. Circular speakers produce sound better than any other shape. And having the speakers be dedicated to a type of sound helps as well. As long as they fit in the factory location no you wouldn't. If you're car has a premium stereo from factory you might be fine.

You can power any aftermarket speaker off of your head unit. Amps only provide additional power for the speakers.

No you will need a separate amp. I bought an inexpensive Pioneer that pushes 150 watts per channel and these speakers sound true and rich.

I have them wired into my car; attached to the back of the driver and passenger seat. For my purpose using an external amp is the only way I could give them enough power, isolate the bass tone, and the added benefit of having a bass level knob is always a plus. If you're doing a home theater system as long as you give them the proper amount of power crossovers will work.

Yes. You need a cable kit to run the power from the car battery to the amplifier. You can find plenty of these on amazon I use a 8awg cable and I think that is way more then what is required for this amp but if you are going to run a cable you might as well use larger as it gives you plenty of flexibility for a new amp in the future. The speaker itself is in a self contained speaker box and can just sit in your trunk (heavy enough not to move and strong enough to handle any abuse. I do recommend a 12 inch grill though... Also available on Amazon.

not required. I can play directly to the amp or use a preamp if I need more volume. It won't be as loud without a preamp but it works fine if all you need is a little boost.

No an amp isn't necessary. But without one you won't be as satisfied. I really like these speakers but after i have them the power they craved I feel in love. Plus they look amazing!

No you don't but it really depends on the amp in your current head unit. The more clean power you can provide to them without exceeding the speakers RMS the better. I hope that helps. Try them with your current had unit and if you need more power then add an amp.

No not at all. They are generally low impedence @ 32ohm so an amp is not really necessary to dtive these.

I do run these with no external amp in a convertibke. My head unit has 45w per channel rms. The speakers sound loud enough to listen with the top down at highway speeds. They also sound clear and balanced when the top is up. You may want to add a sub for a deeper bass.

I installed them in a 2012 Nissan Rogue without an amp. They may not have the same output but you don't have to use an amp. However, you made need a bracket or a way to mount them as they may not fit exactly like the factory speakers. I hope this helps. Good luck.

I concur with the others on this question. You do need an amplifier for these speakers.

I would suggest an amp. You'll all a lot of the deck to run these properly.

No amp needed. Plug right in to iPhone, iPad, or iPod, whatever... These are seriously fine, better than Beats, etc...

Well, most car amplifier are power amp which require preamp such as the car deck to control the sources. Not sure why you will want to bypass your deck.

You will have to find a spot to cut holes. My friend installed these in his 2000 accord so it'll definitely work in yours. They sound amazing by the way. Make sure that you tune the amp properly so they sound the way you want them to.

As the other responses say, yes, you do need an Amp or a receiver. Good Luck

After market stereo will be enough to run these. However you should look to other sparks with higher amps..these went bad after 2 months.
