using JBL BP 1200.1
Going for SPL only
budget $250 or maybe a lil more
music: rap

i had the 12" power hx2, blew it after only pushing like 500wrms or so(when its supposed to handle 1000wrms). so ya whats a good replacement for it. looking for a 2" whether it be 1, 2 or even 3.

or maybe i'm just using the wrong box? i have a 1 CF sealed(what RF recommends for sealed). didnt go with ported cause i cant find one for a good price. i also need a sub sonic filter... but ya it just seems weird that i blew a 1000wrms with only 500wrms... it used to bottom out when i fed it a lil more then 500wrms too.

ludlamdtheory recommended an orion hcca $300(750 wrms).
people on clubrsx.com like elemental designs($135 400wrms)
audiomobile evo-r(750wrms) is sounding good but not sure where to get them cheap
also MA audio D6($99 400wrms) sounds pretty good too
or maybe 3 comp vrs($79 400wrms)
2 alpine type r($115)
so many different choices.. i usually look at the magnet size when looking for a sub. help convince me this isnt the right way to look for a sub cause everytime i look at the power hx2's so huge.

750 rms for orion hcca? hah
theres people giving hcca's at least 1500 watts, sometimes MUCH more...

 
Rep Power: 417

damn you need a huge box tho... 5 CF for ported 2.5 for sealed
imma try to see if my local store carries them

If your willing to break the budget a little, might I suggest:

Resonant Engineering XXX

or perhaps this:

Adire Audio Brahma

Otherwise, take a look at some SPL favorites from Cerwin Vega (Stroker), Kicker (L7), Digital Designs (9912), Atomic Thunder (Mouse) and MTX (RFL).

And yes, magnet size is NOT a good way to look for subs. Although BL (magnet strength) has some effect on SPL (relates to Xmax) Xmax (peak to peak excursion) and SD (cone area) are much better for determining a subs worth, but they still only represent part of the equation. Install is key in any SPL set up.

P.S. For some real experts on SPL go here.

why not get the punch hx2, they are rated at 500 rms at and 1000 peak,

 
Rep Power: 417

eh, dont really want to go with the punch cause its still a fosgate and after my experience with them, dont really want another one right now..

is excursion even a good way to look how loud a sub can get? cause the power hx2's excursion was sick but it didnt sound as loud as you'd think. ya ludlam also recommended DDs but damn costs so much.. i'm trying not to spend any more then $300.

Try soundstream, they make some awesome subs. Excellent quality too.

 
Rep Power: 346

IMO, For SPL I would go with the three Comp VRs...More cone area/cheaper price/Kicker subs always seem to have pretty good SPL

Two 12" Infinity Perfects? Will sound good, and thump pretty good.

yea comp vrs are nice subs, you can also try the L7

 
Rep Power: 337

another vote for HCCA. those ****ers are loud.

 
Rep Power: 417

i was reading some reviews on the hcca and ya alot of people say it hits hard..
the comp vrs.. eh, the place i saw it for $80, their service doesnt sound too great..

oh another setup i'm looking at... diamond audio cm3, $110 500wrms.. how are those? but then i was looking a the specs and it said 500wrms for a .6 sealed and 300wrms for a 1.2" sealed.. i have a 1 CF sealed so i could only run what 350 wrms or so

 
Rep Power: 337

I can get that sub fixed for you and have seen a pair of BD1500's on those woofers......let me know.

Maybe first we should look at WHY your punch hx2 "blew". If the sub was being fed distortion, wouldn't it kind of be exepected that it would blow. My friend had two 15" fosgate HX2's being fed by two fosgate 1100a2's, and they never blew.

Isn't it said that any speaker will blow with not too much power, if it is being fed distortion.

Possibly the lack of a sub sonic filter may be the cause of the sub blowing. I hear all about people on this site with the JBL 1200.1 and needing a subsonic filter.....maybe they need to be buying an amp that INCLUDES a sub sonic filter so they aren't wasting money blowing stuff up. Just a thought, sorry if i insult anybody or any particuliar brands

he doesnt have the punch hx2, he has the power hx2. the punch are rated 500 rms and the power are 1000 rms, and he was only running 500rms on the power hx2, im thinking they blew cuz they were getting underpower, people from caraudio.com say it worst to underpower then overpower the subs

 
Rep Power: 417

damn thats what i forgot to do, ask you alex.. i'm already getting a refund tho, i dunno wasnt too happy with the fosgates.. was definitely not what i expected.. i was hoping that i could run them twice as hard but vc fried and it bottomed out... but ya i hear about people running 100wrms to a voice coil, its weird how i could even run 500wrms to the whole sub... i could always call and say i want to get it exchanged for a new one.. but i dunno, not sure i want fosgates no more
n no it wasnt distorted.. i dont have a subsonic filter but then i dont need one since i'm using a sealed box. whole reason why i went with sealed.. they werent even clipping, i turned down the gains when it started bottoming out.

Grr .... we go over and over this here. Don't mean to jump down your throat .......

Low power does not blow speakers. Distortion does. Put in a set of components and power them with a HU. Do they blow ???? No .... and you better believe they are underpowered.

If your amp can put out 1000 watts .... then it is always putting out a different clean wattage somewhere between 0 and 1000 watts. This is based on volume and musical content. Now on the other hand if you push it beyond its limits it can put out distorted power in excess of 1000 watts (clipping happens etc). This is where your sub blows.

Before I ever got anything in car audio I read up on it until I understood a lot. Do you understand what the gain **** is for on an amplifier????? Do you understand the limits of your equipment ???? If you did I guarantee you wouldn't blow your speakers. With that amplifier and the wrong settings there probably won't be a sub out there that will take it if you keep up doing what your doing. Personally that Rockford should kick *** and last a long time. Its a good sub.

I have never in my life blown a speaker. Ever. Seen it happen to many people, but always because they do something they shouldn't ......

Just curious what you have everything set at. Answer these questions and I bet we can see immediately what you did wrong.

1) What is the max volume on the HU, and what is the max you turn it up to?
2) What is your Bass set to (amp &/or HU)?
3) What is your Crossover Freq at? Where is it set (amp and/or HU)?
4) What is your EQ set at?
5) What is the gain on the amp set at?
6) How was the sub wired?

Wait a minute here.

Power HX2 is dual 2 ohm.

So w/ the 1200 watt JBL ....

Series @ 4 ohms: 600rms / 1,200max
Parallel @ 1 ohms: 1,200 rms / 2,400 max
I hope the parallel number is right. I think the JBL does the same power into 2 or 1 ohm. If not the Parallel numbers should be closer to 2,000 rms / 4,000 watts max.

You said "i was hoping that i could run them twice as hard but vc fried and it bottomed out".
Followed by "i turned down the gains when it started bottoming out".

So I assume you had it in series first, then switched the wiring to parallel.

The JBL is rated at 2400 max ... but I am sure it is more than that. Thats too much power already. Ha ha ..... oops .... looks like you should have turned the gains down first, then turn it up after. Too much power .... speaker go BOOM.

 
Rep Power: 417

alright, i'm sure this is going to puzzle you too cause your assumpsions are wrong(if you assume, you make an '***' out of 'u' n 'me' haha probably only thing i learned in high school)

i had it wired in series the whole time. NEVER wired it in parellel. so max the amp could even put out was around 600wrms. i had the gains to like 1/2 way for a week to "break in the sub"(heard this wasnt even necessary but did it anyways). then on the 2nd week i had it up to 3/4.
so ya it was only wired in series, and i was hoping to be able to run it in parallel and run a lil bit more power to it but i never got a chance to...

1) What is the max volume on the HU, and what is the max you turn it up to?
about 32-34, max i turn it up to is 27-28
2) What is your Bass set to (amp &/or HU)?
all the way up
3) What is your Crossover Freq at? Where is it set (amp and/or HU)?
is kinda hard to tell exact number but i was listening to it. very close to the beginning tho
4) What is your EQ set at?
dont have one
5) What is the gain on the amp set at?
3/4 max.. i put my HU to 28, gain to 0 n started cranking up the gain till it started bottoming out then turned it down a notch
6) How was the sub wired?
series the whole time

so now you know why i'm puzzled and i'm not too happy with fosgates...

Generally setting the bass all the way up is bad. This usually leads to a distorted signal. Distorted signal into the amp yeilds a distorted signal out.

If this was the case, I would think that was the culprit.

Usually its better to leave the bass at zero and turn the amplifier gain up more if you want bass. This way you are working with a cleaner, unboosted signal, especially near higher volumes.

I just don't understand how you could blow that sub if everything was hooked up right. If thats is the case, that it just blew, I would return it for another. Maybe it was defective the whole time ..... that sub and amp should be absolutely bad ***.

 
Rep Power: 417

i'm pretty sure nothing was distorted but even if it was, i dont think it would cause the sub to bottom out would it? i thought this setup would be badd *** too and was very dissappointed when i found out i couldnt even take it to 1ohms. had an option of a refund or exhchange but i asked for a refund. i could always try to call and ask them to exchange it but ya not sure if i want another fosgate after my experience with this

 
Rep Power: 346

Honestly, i think that VN just got a lemon...not only was he running it a 4 ohms but it was in a sealed box as well. I would hit up Alex who works for RF and see if he could hook you up with a free repair, and just stick with that sub. You have been looking into subs for awhile, and that is the one that you finally chose, so if you had a good one it will prolly suit your needs...so I would stick with the RF sub. IMO that sub should be able to take the full 1200 watts of that amp, if you wanted to wire it like that and you set your gains right.

 
Rep Power: 417

haha ya i've been buggin everyone for months maybe even a year... i dunno maybe my expectations were too high? maybe it was a lemon.. i already sent in the sub asking for a refund but i guess i'll try to call on friday and see if i can just get it replaced. hopefully the new one will be able to handle the whole 1000watts it says it can

Didn't mean to jump all over ya, most times posts like this are newbs that max everything and just do stupid things.

I agree that sub is very bad ***.

I got an Eclipse Aluminum ... but I was also considereing Power HX2's and JL W3's this summer when I got it.

IMO it doesn't get any better than that sub for the most part.

How loud was it getting ???? Was it in the trunk facing toward the rear of the car ??? My 12" single, sealed, off a 400 rms kicker amp .... has to be in the 130's I would think.

The more we talk ... the more I wanna say you got a Lemon.

 
Rep Power: 417

i usually drove with my rear seats folded down. it was pretty loud, very deep. the pressure was there cause on this one part of '50 cent - in the club' you could feel your hair move slightly. even with the volume up i could talk to people in the car pretty easily tho. it wasnt like i had to get up into someone's ear and yell or anything like that..

with the seats up, now thats a different story. it wasnt as loud and ya you couldnt feel the pressure.
i had my homegirls in the car and they hate the bass, i just wanted to show them my system so i bumped it to 28 on the headunit and they werent even annoyed...

i dunno, i cant say how many dbs i was hitting cause honestly i never been to a comp or had anything measured so i cant really compare. if i get it i'll let fonto mess with the gains and let him hear it just to make sure i'm not the only one trippin. hopefully it wasnt just me and it was a lemon...

haha...you shouldn't let me anywhere near the gains!!! i am either way too conservative, or I just get fed up with trying to balance everything and just jack it up!! [IMG]i/expressions/face-icon-small-tongue.gif[/IMG] Anyway, maybe one of my homeys will come to a meet and set your ish...he actually went to school for summers on that stuff, so he knows what to do...and he always tells me what i need to correct!

if i cant get it exchanged imma try to get the HCCAs. do you think i can run the hcca's in a 1cf sealed with a pound of polyfill? those hccas require a HUGE box

 
Rep Power: 346

How much are HCCAs and where can they be bought online?

 
Rep Power: 337

The problem was it was in a sealed box..they sound like booty in sealed boxes and need a ton of power to move. Put that bad boy in 2.5 cubic feet with two 4 inch ports (or 25 sq inches of port) 16 inches long and it will hammer away. I bet the gains were close to pegged to get that thing to move....The hcca is a good sub. I head the new ones at CES...two 15's in a bagged hummer H2 on 24's...Install by Edge Audio (Scott Owens) in Tempe. they were loud for sure.

if they need a ton of power to move in a sealed how come i blew mine with so little power? its weird..
ya i was using this box just as a tempt till i could find the right ported box.. didnt even last a month tho
