Do you need an amp for these speakers?

Yes, these are passsive (non-powered) speaks, so you will need an amp or receiver.

Yes otherwise you will not get the best of them. They are big speakers and need extra power. I have an amplifier on my boat but not sure how big it is. I have the smaller speakers not connected to the amp and works well this way but will be also connecting them to the amp.

You can install them without an amp. These just respond really well with more power. They love to be cranked up!

No I have not, but if it's a 4ohm rated amp I wonder if there will be adequate power to sufficiently power them (depending on your needs), as these are 8 ohm speakers.

These speakers are not self powered. You will need an amp of some kind to power them. They are good speakers for the price. I like mine.

I did not need an amp for these units. I am using an pioneer avic navi unit. Any upgraded stereo unit has more than enough power to run these and still sound good

You CAN, but that's probably not the best idea. These are passive speakers which require an amplifier vs active speakers which don't.

I think that would be pushing it. They sound great, but that's in a relatively closed environment. Take a look at a speaker brand called energy take. They are Inexpensive, and an incredible bargain. You would need an amp, but you could try finding a cheap used one. Have fun!

Probably not, your going to need a amp otherwise they end up fairly underpowered

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

You will need an amplifier and an audio box to connect the amp to your PC. These speakers become more expensive than sticker price when amplifier, audio box, and cords are considered. I would NOT purchase these. Spend the extra money now on a pair of good self-powered speakers and an audio box and thats all you'll need. Spend the money on that stuff now or spend MORE money on these speakers as you go.

You really need an amp, these speakers are very loud since they are for competitions, I would recommend you getting some marine speakers.

You need to buy a speaker system. You will not need an amplifier if you get a powered speaker.

No. They are very efficient and sound great with iphone, ipod classic, and even spotify streaming. Sound GREAT!!! No need for amp. They are very loud with volume at about 75% using iPhone 5.

No, these are just speakers and have no amplifier. You would need to have a receiver connected to them.

Yes, if you only have a head unit with no built in amp, it would be a good idea to get an amp for these speakers. They will still work without an amp, but they won't be as loud or have hardly any bass. As for which type or size of an amp to get, I can't help you there.

No amp is needed, but I have mine hooked up to an amp just to give them that little extra kick.

Yes, the head unit will push them and they will sound decent, but you won't be able harness their full potential without an amp.
