Just plug them in to the head unit. That's what I did for mines and they sound just fine.

No the crossover is seperate, but my 4 channel amp has a crossover so I just tuned them with that. To be honest if your amp has 1 buying 1 is a waste of money, and there very very loud, mean as hell haha

They do not come with an amplifier, just a crossover. So, you could power them from your factory radio, aftermarket radio, or a separate amplifier.

yes they do come with a crossover and i would use them they are perfect match for the speakers it will sound clear and filter out the bad stuff most likely there is either an amp supplying power to just that tweeter or there is a resister in line that is acting like a crossover in you 05 acura in either case i would us the crossover that is with the pioneers, i have them on there own amp 4 channel for my highs and mids very happy .

these will run fine with the onboard soundcard. they're easy to drive plugged into just about anything.

I used Audio Express for my install. They did an excellent job and have compatibility info on the stereo units. Pretty sure theyre nationwide too. They shd be able to answer your questions. Good luck.

It all depends really. If you have the original radio then yes, you should run an amp to them. I currently haven them hooked directly to my Pioneer head unit with 22 watts RMS and they are quite loud at 3/4 volume. I do plan on running an amp later on to boost them up a bit.

what are you hooking up if .you have using a parking brake override,its make to hook up to head unit only.your headunit should have a braking brake wire ,you do not run a wire to the braking brake

If you hook these to your factory radio, they will be a huge improvement over the factory ones, but if you really want them to shine get an aftermarket amp / head unit. If you are comfortable splicing wires, you should have no problems hooking these up. Just Google the wiring diagram so that you can make sure that you connect the right wires to the correct terminals.

No crossover is needed. Just wire together per instructions and you'll be fine. Fyi the small tweeter is loud.

you can however without the tweeters installed you would be missing the highs. they sound great without an amp with my alpine head unit. not sure how they are with a stock head unit.

No this particular amp has high, low, and a sub crossover so an external crossover is not necessary.

You dont, but definitely sounds better with a clean 50 watt or high per channel amp. I have them in 2 cars one right off the head unit and the other off an alpine 4 X 50 watt amp.

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.

I did not use crossovers, as the focal's did not include their own. Instead I used the high pass filter on my amp and things have sounded great so far. The amp I am using is a Phoenix Gold V754.

They will work and will sound just ok. If you could amp them even it's a small amp they will shine though. Yes however these speakers have high sensitivity ratings and will work ok off just aftermarket headunit power alone.

Unfortunately, no. These really need an amp to drive them. They just won't sound right without. You need something made for wattages similar to what your head unit can deliver.
