Question speaker help??? trying to understand speaker specs....

Looking updating Betty's speakers... I'm looking for 2 sets of 5.25" speakers, that are fairly inexpensive, yet have decent quality set speakers that sound good for my TJ. I'm not looking to cut 6.5" speakers into my sound bar either, though may help a little with sound/bass.

So tonight I get on Crutchfield and look... I became confused as to specs... So I chose 1 brand for comparison. I chose the Crutchfield brand - Sound Ordnance... size 5.25".

I limited my search to the 5.25" size and the same brand.
I came up with 2 choices. one for $40 and one for $80.
90% of time, I'd say... the $80 one would be best... right?

Sound Ordnance™ P-52B vs Sound Ordnance™ P-52CB

Well I decided to look over specs... And other than the $80 set rated at 2-50w RMS vs $40 set at 2-40w RMS... If I understand the link below...the specs seem to be better on cheaper set...
I'm wanting full range and a little bit of bass... the crappy cheap Dual 5.25" I have now... sound ok, but very tinny, but honestly don't recall their specs.

After reviewing this link... (and yes, I realize that this link is for home speakers, but assume the science/info is basically the same)
I feel that I should go with the $40 set....
Is my logic incorrect?

I listen mostly to 70-80's Rock and 80's Hair Bands.... Not Looking anything crazy... just better sound than I have now.

I am using these dash pods in the dash now with the cheap speakers

I almost think the speakers sounded better with out them...

My head unit is a cheap aftermarket unit. DUAL Presently, I do not have a sub either.
I'm not putting in a better unit, in fears of it becoming tempting to a thief.
I don't recall the output on the unit... If memory serves me correctly, it says something like 60W or 80w x4.
I like it because I can use an USB or a SD Card for digital music... 90% of time I listen to FM, but on the days I want... I can listen to RATT until my brain explodes.

I like music, but not really don't understand the science behind it all....
So hopefully someone can help me understand what I'm finding... I'm not saying I'm buying the S/O speakers from Crutchfield... I'm trying to use them more as comparisons.

I am not a sound aficionado but, nobody driving a jeep should be either..

you are comparing fraternal siblings as to your speaker choices. One handles 20% more power, the other is slightly more efficient at making sound.

Impedance is the same, frequency response is virtually identical but the lower power version is slightly broader, bet you could not tell them apart in a blind hearing test in a jeep.

Looks like what your setup needs is a powered subwoofer so you can rock out without distorting these little speakers.

I tried out a few brands trying to find the right speakers for my Jeep, the GTO line of JBL is the choice I made... they have good range from low to highs with out the need for a sub or external amp, fyi I run these with a Retrosound radio (25 watts x 4 | 2-4" & 2 4x6")

Your jeep has provisions for larger speakers & better sound insulation than mine, so I can only imagine sound would even be better.

Amazon is the most cost effective way to purchase these.

If your top is off all bets are off though

Your head unit may claim differently, but it is maybe 4 watts RMS, 8 watts if you are lucky. Since you do not want anything complicated, choose the most efficient speakers possible. (Will be listed as sensitivity in dbs - the higher the better) You may also want to try 2ohm speakers vs 4ohm as it will double your amplifier output if your head unit can handle it. Considering what you currently have, new speakers won't matter much without a new head unit or external amplifier so I wouldn't spend a lot in them.

Bob I'm a little rushed for time right now so this will be brief but it may help without getting technical.

There are really two key specifications for a speaker that need to be understood.

Its wattage rating and its sensitivity rating... they are crucial and they affect each other.

First, a speaker's wattage rating is only how much power it can handle before it starts distorting, not necessarily how loud it will be at a given volume setting on the radio. A speaker rated at 500 watts may be barely audible with a standard head unit while a different speaker rated to 60 watts may be loud and clear at the same power setting on the radio (head unit).

That is due to the speaker's 'Sensitivity' rating which is how loud the speaker will be when given a certain amount of power. It is rated in decibels, or dB. A speaker with an 84 dB Sensitivity rating is going to take a lot of power to drive loudly, so it'd need an aux amplifier since a stock head unit isn't powerful enough. A speaker with a 92 dB Sensitivity rating however is MUCH more sensitive to the power it is receiving so it'd be fine with the power generated by a standard/stock radio or head unit. Polk speakers are known for high Sensitivity ratings.

The speaker's wattage rating just needs to be above the maximum power the amplifier can put out but pay close attention to the speaker's Sensitivity rating. No matter how some manufacturers may try to make you think that 250 or 500 watt speaker is going to blow your socks off. It will if you have a big powerful aux amplifier, but it definitely won't with just a standard radio or head unit.
When you have a choice, buy American.
