Do these speakers require an additianal amp to push them appropriately... or would a head uinit similar to what would be installed in a car work..?

These speakers will require an amplifier similar to any loudspeaker in order to reproduce a full frequency signal. I am not sure what you mean by a head unit but if you mean the signal strength used to power headphones, that would be insufficient. You need an amplifier capable of a minimum of 20-40 watts of power into an 8 ohm load. Hope this helps.

I'm pushing them with the waterproof head unit sold by TIC and its working great! It is a marine grade stereo head unit more or less.

Not necessarily, assuming your head unit has a built in amplifier. It's always recommended to match the RMS of the speakers with an amp output though... plus they sound much better :)

They require a AV -Receiver or a separate power Amp. I used these for rear surrounds for years and they were the bang for the buck for sure. Good sound too!

It depends based on your speakers. If they're very hard to be drove, you need to consider other AMP for them.

No you don't, however I would not recommend hooking these up to a stock/factory stereo. I am using these with a Alpine CDE-123 and they sound amazing. Very good bass, mids and highs. These speakers can handle 100 watts RMS, which is a ton of power. In order to really push these speakers to their best, you would need to amp them. But that is a whole other beast. If you're one to amp these, then it's probably because you are adding a sub as well. I hope I answered your question. Let me know if you need anything else.

They are 4 ohm speakers. They need some power to drive them. They can be ran without an amp if the head unit has enough power. I would say a min of 30 watts per side but they will sound the best with 75 to 200 watts.

99% of cars will require some sort of modification to make these work. This is not the speaker to run unless you are doing a full system and plan to run these of an amplifier.

These speakers are excellent but need to have an amp powering them to truly appreciate. Go to crutchfield.com to check compatability with your vehicle.

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

Wire your speakers normal. But drop the resistance on the sub. It should push it no problem

Yeah, I agree with Claudio. It would push them but it would probably overheat and go into protect mode before getting anything near the SPL that those 2 12's can make. You should get a 1000 watt amp instead and run them with the gain turned down a little so that your subs don't distort. You'll have plenty of headroom for your amp as well so that it runs cool and smoothly with no signal clipping.

You would absolutely need an amp. These are home theater floor model speakers and not small computer speakers. They are loud when they are hooked up to a loud amp.

If im not mistaken a aftermarket/stock radio pre-amp is 45x4 or 50x4 meaning your slightly better from amp than running from headunit. Depending on amp actual power may be less than advertised. it will work but dont expect them to be much louder than stock speakers. i have a 2500 watt 5 channel amp running 100 watts to each to these(and they could have more, but plenty loud with just 100watts) and the rest for subs.Side note when buying amp/ speakers you want the amp rms at least 80% of the speakers peak for best results.

No ,you need an amplifier or a audio receiver to use these speakers cause they are pasive not active.

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

You should consider the extra load you are going to place on the amp. Sound isn't just speakers but the sound power you have available to put through. Is you are replacing these with similar powered speakers, fine, but why not get s not pedi system if what you want us more sound?

I'm sure it will. But to be honest I never installed door speakers without an amp. An amp will give these speakers a little more clarity. Some head units barely push these speakers. I believe if you go the the process to upgrade your sound, might as well go the whole way. Find a cheap amp and get the best from your highs.
