what he said

go to shops/shows and research.....car audio is fun as all hell and really easy. You'll be glassin kicks soon enough cuz you're not happy with the stage.

and don't buy cheap shit....you'll get what ya payfor. Oh and do all the install yourself...I used to work for a custom shop in toronto....man o man, you'll be ripped apart dude. Trust me.

ever heard of ohms law? next your going to say that shorting out the speaker wires won't put load the amp because its 0 ohms.
or gee wiss my amp sure runs hot ,duh maybe im using a lot of power to run those 2 ohm subs, sure the damn things louder but think of it, more power less efficiency/ and maybe you should research the term DYNAMIC HEADROOM.
Defy the laws of physics eh? If you want to attack my technical saavy, I suggest you at least back it up with some sort a logical argument instead of a tirade....

What's funny jrich, is that you never even say what ohm's law is. V=IR, and second, take a look at a speaker's sensitivity (effenciency rating) at crutchfield.com. While a speaker may sound louder with a higher sensitivity, it won't neccessarily sound better. Get some Alpine speakers.

Also, rcurley55 doesn't defy physics. Wake up jrich and learn to read and write properly. Maybe you need some physics and english courses??

" most effecient as possible, this way your speaker will be loud without using all your power"
josher where in this statement do you see the most sensitive speaker sounds the best?
its all personal taste and you saying "Get some Alpine speakers" is stupid, maybe to lalno1 they sound like crap.
i like accurate sounding speakers with good mid bass response. if anyone wants to know what i prefer i'll be glad to tell them, however that doesnt mean i should shove my opinion down ones throat.
and anyone that doesnt know ohms law, or how to make there own crossovers go to www.ohmslaw.com

So what you are saying is that we should all run HLCD's?!?!?

Why do you want to buy speaker's based only on effeciency? If you're so concerned with effeciency, sell your car and buy a more "fuel effecient" honda civic hybrid. Or maybe ride a bike?

My point is, you need to buy speakers based on how they sound to you, not effeciency. I highly doubt Alpine speakers sound like crap to anybody. And also, going to Best Buy, Cicuit City, ABT electronics or any speaker store and listening to car speakers mounted in a wooden board is not an accurate representation of how they'll sound in your car.

Lastly, I don't consider telling people to get Alpine speakers to be shoving it down their throat. Its simply a suggestion, which if someone reads, they should research and then decide. Shoving it down someone's throat here would be flooding this thread topic with Alpine Speaker links, pics, and other people's opinoins.

I actually work for an Electronics store and trust me when I say manufacturers LIE! The specs that you see on paper do not mean jack! If what we saw on paper were true we would all be listening to Pioneer speakers since they outperform everything on the market based on the box specs. Additionally Alpine speakers are very inefficient and their component and type R speakers are among the worst that I have ever heard. The CD Players on the other hand are great.

Additionally if you have a five channel amp it may not be a good idea to run a sub at two ohms. Some five channel amps will share capacitors with two of the other channels. Additionally you will cut the life of your amp if you run it at two ohms. A decrease in impedence causes an increase in current draw and therefore creates more heat. If you have a high quality amp and must run the fifth channel in 2 ohm buy what is called a "Dual Voice Coil" or DVC sub and run the channels in parallel. :naughty:

There is also the point of deminising returns. After a while you spend more and more to get something that is no longer noticably better. Install also has a huge impact on how speakers will sound in the end.

If we all wanted just effiecency then we would all use bandpass boxes too.

Bandpass boxes work best for trucks since they have to be much bigger. Nearly twice the size of a sealed sub enclosure.

Second, I own Alpine type-R speakers while my friend has Pioneers. And lets just say mine sound a hell of a lot better.

And the specs on paper on paper are usually right. I doubt a speaker company would lie about the volume of their speakers. They will however, run their tests with cars at 14V and at beautiful temperatures and atmospheric pressures. Of course the specs given by manufacturers are ideal, not lies. You just have to know how they find their numbers.
