Was it a Bunch of BS

Ok this one guys at my local shop told me that the jl 500.1 pushing 3 he's would sound so great and that it is so efficient that it will sound better then the RF 800.2 will it or was it bs

Also how are the Ma audio amps or any other ones than you very much

i think it's bs. the jl is an awesome amp, underrated and everything. the rf amp ia also a great amp, underrated and all. however, i believe the 800.2 will be a little more powerful rms wise. i could be wrong, the x-factor are the subs impedence and what the amps can handle. you said "he",so your talking the svc model right? unless the jl will handle a lower impedence level, i think the fosgate wins here.

again i could be wrong! that's just my undereducated opinion!

hey thanks for posting let me knwo what u think of the ma audio amp

 

[mrray13 10+ year member]

i don't have any experience with MA audio. i can't remember, but i believe i've seen here in the forum where they were okay. i'm the wrong guy for that question, sorry dude!

I think I have seen zane knock MA, but I could be wrong.

rockford rates their amps at 2 ohms and 14.4 volts... they under rate very little anymore as compared to the early mid 90's....... least i know this to be true about the punch line............

any magazine that has tested the jl amps has never said anything bad about them, good sq, great power, but @ JL's rip off price.

 

[mrray13 10+ year member]

to audiolife... i think the power series is rated the same way

to taylor... is truly a ripoff price if it does more than it says? i don't believe i've ever seen or heard anybody knock jl (except the kicker vs jl speaker thing here in the forum and zane[jl] won that one to a certain degree). anyway, most say you get what you pay for,right? is quality worth the cost?etc,etc,etc....

liwaj79..either is a good amp, i think the rf is a little stronger(shi$, it's rated bigger to start with!)even if it's true to it's rating it's a stronger amp, unless the jl is just way seriously underrated. and it could be! someone with a little more jl experience here?

i think its like comparing a turbo charged v-6 against a good v-8 ...... dont think he will go wrong either way. when it comes to something like this i usually tell a person go with their gut choice...... nothing will ever get to you more than changing your mind at the last second and (even if it is a minor difference between the two) wishing you went with your gut. the class d jl has power usage advantages vs. a class ab 800 though. meaning its a little easier on your car.

thats one other thing that the guy told me that it was the most efficent amp and that the rf only gives you 800watts %20 of the time while the JL gives u 500 100% of the time.

yeah on power on demand wise ...but what i was talking about is an amp takes power to make power and a class d amp does this easier on your car than what the 800 would. if you only plan on adding a cap then the jl would prolly be better...depends on the car's alternator and battery but most of the time for the average user "easier on your car" is a good way to go. i sold an 800 to a kid with a grand am...needless to say it drained his electrical system pretty good. he could have had a bad alt or battery but on the flip side to this is if the amp needs more power a cap wont really help that much.....it is more of a stablelizer than a true power source in a common use. i know there be ways to say different but i am talking purely simplistic here (has seen 30 caps in a car before but what long term use is a cap if it doesnt get its power?) i would look at your alternator and see how much power it can spare unless you want to beef it up with more than a cap before i made my choice.

I just picked up the 500/1 (and a 300/4) and have to say that these amps are impressive!!! The 500/1's regulated power supply lets it put out it's full rated power (and then some) at real-world (i.e. stock electrical system) voltages. The on-board adjustments on the amps are enough to keep me tweaking for weeks. I have had no problems whatsoever with these amps. If you are looking for them cheap, look on ebay. I bought my 500/1 for $369.00.

the car electrical system part is something often over looked...and prolly the number 1 reason i suggest class d . course i dont think about it that way i have an ohio genorator 290 amp alternator and 4 svr batteries lol

As audiolife n all the others say --> JL is great but far too expensive for 500RMS amp. Rockford have always been a good, all round brand. Ive seen 800.2 birthsheet with 1300RMS, so these arent short of power. If JLs were half their price, Id consider them, but I think rockford's quality AND VALUE 4MONEY may suit some better

(ANYONE FROM JL PAYING ATTENTION TO THIS?????? EXMPLE - W7 - over $600 for the 13.5 version. $600 will but subs that are as good, even better in my opinion - IDMax, ECLIPSE DVC's, Shockers, DD, Crystal - u name it and youll still have $$$ to take yor girl out, get some cables, some new cds, custom made box - the list goes on. JL make good products but i think the years of research and staff costs are, as a result, passed onto the consumer = (

In england, JL importers are charging the equivalent of $1400 (not a mistake) for a W7, possibly cos of JL's US price and the way imprttax works over there. $1400 will buy you a system, not 1 sub!!!!!!!

NE1 ELSE AGREE OR AM I JUST A WHINING A$$??

most shops will "wheel and deal" and you even have online to buy them...i seen the 500 going for 400 on line....i am not argueing your point that rockford is good and maybe some brands are over priced...i will agree about the w-7 i think its price tag is a bit steep as compared to the idmax....just like the idq woofers help their own against the w6's for less money....but you have to understand jl audio's marketing. it is set up for shops to make profit..they only want in quality stores and in turn the shops get a profitable, well know and demanded line. they all go hand in hand...they are in bizz to make money and the end result is a happy customer(although thinner pocket book). i work retail i have for years i also reped a line or two for a year. ok more than 2 lines but i understand how it all works. the shops need to put food on the table just like you and so does the people at jl. when they break a mold in a woofer that they cant get parts for by standard wooffer manufactures ...like eminence.. things become costly. eminence might even make the parts but again new machines were prolly needed.....yanno there be alot fewwer woofer manufacturers than you think... many "woofer" manufactures contract out. same with amps....when it isnt so able to be massed produced it becomes more costly. rockford was never affordable until they went into crutchfield and best buy..why? because they sell more and stores order more massed produced product. i know the power series stuff isnt in best buy but it frees money up to lower the overall price of the good stuff so they make their money in turn by selling more product at less profit. rockford and jl make money from selling to stores and the shops in return make money selling to u this is true in just about everything that is retail so i dont think i am giving away any trade secrets. and if jl and rockford all make their own parts so be it most dont .......but i will guarantee that the w 7 takes different machinery to build than a w3

So how will this sound 3 12" he's RF 800.2 with a kenwood 617 Hu Rf cap?

 

[audiolife 5,000+ posts]

ok but i think you might get better results with the class d amps. the jl 500 sells for 30 bucks less on line than the rf 800 and you can buy the jl in confidence as long as the net shop sends it lol which most do

 

[liwaj79 10+ year member]

Could someone tell how many watts the jl would put out at 1.5 ohms I know its puts out more then 500 I was just wondering

 

[liwaj79 10+ year member]

Also could some one some one tell me how much louder it will be with my steup right now i have 2 hes' and a 600 sony amp going to them bridged at 2 ohms thanks

 

[audiolife 5,000+ posts]

500-580 the amp is sorta set up to do just that..in an application such as yours it would be great...sony rates at peak prolly 300 rms with no headroom. lol lotta factors though that you wouldnt have with the jl
