do you have to run an amp to these speakers

These are pretty efficient speakers. If your deck has speaker outputs then usually they are good enough, you don't need an amp.

No, these are are replacement speakers and will work as is. You might want to use adapters for the wire connections if space is limited. It makes the installation easier as you don't have to splice the wiring.

These are great speakers. I am using them with my home Stereo. so they would need an amp.

Unfortunately no. You need a receiver to run these as well as seperate speaker wire to connect all the speakers to the receiver

These are passive speakers. They do not have a built in amplifier. You will need a outside amplifier. I am using an older pioneer stereo amplifier to power the speakers.

You do not have to have an amplifier on these but if you want to truly experience what these speakers have to offer I would highly recommend a minimum of 50 - 75 watts to each speaker or channel. For optimum sound I would recommend 110 watts per channel, it does make a huge difference in sound quality and clarity.

No they are not, you will need a amp. However for the cost they are a great speaker and the sound quality is great for DJ and parties.

As the guys answered before, you need an amp to properly power these speakers or you will be disappointed.

An amp.is probably required to power the speakers if their watt rating is high. If the wire is RCA to bear end speaker you could give it a try directly to the speakers. If it's RCA to RCA I wouldn't cut the end of the wire for speaker connection.

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.

You don't have to buy an amp. The only way to damage these speakers, would be to overpower them or literally break them. They are great speaker on their own, but the way to get the most out of them is to get an amp. A 250 watt amp is ideal for these speakers.

These speakers are power hungry, I would not recommend running them without an amp, I fear you would be disappointed. The also sound a lot better in a sealed box. I had them mounted in my electra glide, and since the speakers are not air tight they did not sound nearly as impressive as in my boat in a sealed box.

I believe they are the most efficient car speakers made. I run mine without an amp. Why don't you try this first? You can always add an amp later.

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.

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. 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.

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

I dont know what kind of amp others are using but these speakers DO NOT need a sub. They are good down to 30hz.But yes, if you want anything lower than that, than yes, you will need a sub.
