Correct. I'm pretty sure there's no crossover in the amp though, I think the range of the rear speakers is just limited by their natural rolloff on the high end.

For a given amp, yes. However, if an amp is only 8 ohm stable, it isn't necessarily cleaner at 8 ohms than a 2 ohm stable amp running at 2 ohms.

The crossover is in the amp. I wires up a 3 way 6.5" speaker, got nothing but low range, very low midbass.

Hmm... Interesting. Then again, bottoms of the rear doors aren't the best place to put tweeters anyway, so it's probably not an issue in most cases.

i tried my best to seal them off but there are just so many leaks

Makes no difference where it's stable. Being stable at 2 ohms doesnt make it clean at 2 ohms. All that means is the amp can sweat off heat fast enough with a 2 ohm load not to overheat and shut down. There are high end competition amps out there rated down to 1/4 ohm and produce crazy power. Its raw dirty as hell competition bass kind of power, thats all they are good for.

82.4 is terrible. The higher that number the better and that goes for any speaker. PYLE is named perfectly............ PYLE.............

One for tweeters, one for mids, one for subwoofers. Doing it right costs big money.
Ohh I was just wondering if you knew what brand it was one midrange speaker is 400-600$ their very crisp and carry their sound very far and still sound good. I know how to build a loud system give me some AQ amps (forgot model) or some dd m4as run em strapped those are 7500watts at 14v put 8 dd supercharged 3515s in a tunnel ton of xs power 14v batts and 2 new h/o alts and then fiberglass the doors throw some good mids in blah blah. Or if you want to be a *** get a old school civic hatch back with a DC 12inch lvl 5 in a octaport on 5k and get 160dbs at comps. Fuvk the hatchbacks

You have been in the business for 18 years yet used some of the biggest POS cheapest junk speakers on the market in your own vehicle? You then post up specs of 82.4 DB sensitivity as if thats something to be proud of? Sorry but that doesnt give me much faith in the thing or two you may or may not have pick up on.
