Do my subs need more power?

I have 2 10 inch 10W0 JL subs in my car...and I'm running them with a 60 watt RockFord Fosgate Amp. My friend as the same set-up but is running a 200 watt AudioBahn amp for his subs. His seem to sound alot deeper, louder...and clearer. So....do I need to get more power to my subs?...a bigger amp?? Mine sound great they way they are...it's just that my friends sound better....and I was just thinking I might need more power to them....60 watts really isn't much...I've heard that JL's starve for power...is this true?

60 watts is a bit low for subs. i'd give em more power. jl says around 125 watts rms for those subs, i'd go with somewhere around 100-150 watts a piece and you should be fine. just dont get an audiobahn amp

I pulled this off JL's page


<img src="http://www.jlaudio.com/subwoofers/images/10W0.jpg">


The 10W0 is a potent 10-inch subwoofer designed to extract maximum performance from small to moderate power levels. Highly flexible in its application, this speaker works extremely well in sealed, ported and even bandpass designs.

Nominal Diameter: 10 inches (250 mm)
Continuous Power Handling: 125 Watts
Voice Coil: 1.38" diameter, 6-layer, Kapton former
Available Configurations: 4 ohm or 8 ohm (Single Voice Coil)
Xmax (one-way, linear): 0.34" (8.6 mm)
Sealed Enclosure Range: 0.50-0.90 cu.ft. (14.0-25.5 liters)
Ported Enclosure Range: 0.90-1.50 cu.ft. (25.5-42.5 liters)
VRC™ Technology: YES

<font color=red>
What I think? yea.. I would put atleast 100w rms to them, and 125rms like they recomend I could almost guarantee a big difference.

To me Audiobahn looks like a good name. I bought two of their 10" subs (AW1000Q) but havent hooked them up yet. I mean... they do make subs that go up to 2000w RMS so I would imagine they have some quality stuff. Not sure about their amps... but I'm keeping faith till I hear the subs I bought. I woulnt say they are junk or anything, now something like pyramid! HA! that I would call junk. Or lol Thump! Those speakers were like 10 bucks for a 12" LOL! thats just funny...

Audiobahn Amps

ok maybe this is why... maybe someone else can explain to me why these amps are so expencive O.o I mean.. for the watts its putting out these prices are pretty high. Well.. maybe because its the oem site and they always markup the retail high.

Audiobahn...where do I start. They are the "bling-bling" of the mobile audio world. I would be hard pressed to say they make total junk because some of their upper line makes (amps) and takes (subs) a lot of power. The thing is the company spends more time of the looks than the performance. For the price, if you are looking for more good sound that looks they are great, but if you are looking for more sound than looks they kinda fall behind. I would suggest looking into JBL, MTX, or possible Kicker.

JBL makes a good mono amp, so u can wire them in parallel and get more watts out of it.
Also, do you have a crossover or eq, i think that makes a big difference (at least in my experience)?

those old fosgates were way underrated. what is the preout voltage of your head unit?

no, that amp isnt the MOST powerful amp in the world, but for its size it is a screamer, so if your buddy has an audiobahn 750w it will hit harder, unless the subs are already at their limit.

another thing, unless im missing something, is that the box design is going to have a very distinct effect on sound.

I have a MTX Blue Thunder 375 watt amp running one Kicker 12". I would say yes you need more power to the subs!

no. your head unit does NOT do 50w x 4. i was talking about your RCA pre outs.

i dont care what it says on the front, your pioneer, jvc, kenwood, sony, blaupunkt.... WILL never do 50wx 4. even if it is struck by lightning.

luvmy92
what does the fact that you have 375w on a kicker 12 have to do with anything?


the w0s are a good sub, but make sure you have everything else lined out, i would run either dual 8 gauge or 4 gauge power/ground to the amp, see if it likes that, normally it does.

are your subs wired to 2 ohm mono? are they 4 or 8 ohm subs?

i had a punch 55 on two HE fosgate 12's at 2 ohm mono, and i never had any problems. sounded great

First of all....you don't have to be all cocky about his. What does it my head unit produce then?...because last time I checked that's what the face said.....how am I supposed to know about the RCA pre-outs? I just want to know if my subs need more watt's. I don't know much at all about car stereo...I just want my subs to sound a little better. I could almost care LESS how loud they are...I'd rather here my exhaust ANY day of the week. I'm not a little ghetto thug wanting to break out my windshield or anything....I just want them to be a bit clearer and smoother sounding.

I guess nothing Onebadwagon, I guess I will refrain from typing anything as to not envoke your wrath oh great one.:hail: :hail:

I was pointing out that I had 1 speaker with more wattage going to it then he had to his 2 speakers. I really wish some people would stop being so damn serious about everything on here!

you purchased the head unit, knowing the preout voltage is knowing how much power your head unit is giving your amplifier.

you said that your friends subs hit LOUDER in your original post.

luv, i was just wondering what you meant by that, the w0 are JL's entry level speaker, they dont want alot of power, i can show you subs that will reliably take 1500w, but that doesnt mean that his will.

84custom, dont be upset, no head unit that i have ever seen in the world, nor have i heard of will do 50x4, there is a reason that every amp that will is 4 times the size of your radio.

i asked about his enclosure compared to yours, i also asked how the subs were wired and the impedance of each speaker.

i am only trying to help.

Ok....so what does 50WX4 mean then? Did they just print that there because it would look cool?....you said that "no head unit in the world will do 50X4" then what does it mean?? That's all I'm asking..

Well the whole thing is head unit ratings are a little off.

Check this page out http://www.installer.com/tech/headpower.html

Another thing to remember is there is power lost going threw a wire. (kind of hard to explain) That's why people use big wire like 1/0 for a main battery to secondary battery if they have to go the car length.

How many people have you seen mount an amp in their dash and run a small wire say 8 guage all the way to the hatch and push a 1000 rms sub? Probably none. The idea is to put the power maker as close to the outlet (sub) as possible.

Hope this answers your question.

first thing, the audiobahn. pretty much everything i was gonna say has been already stated. the r!cers of the audio world; all show, little go.

next, headunits are a funny thing. if you use pre-outs, your're not using the internal amp, hence pre(before amplifier) outputs. they are rated by voltage (usually between 2 and 4 volts). the reason why people dismiss any wattage claims maid on headunits is because they are inflated ratings. 50 watts per channel is max, and these maxes tend to be "when lightning strikes" (aka just about never). usually put out much closer to the rms, but these too are often inflated. since you are using pre-outs, the wattage rating on your headunit has no effect on your system.

the reason why your friend's setup is louder is because he is technically putting out more power to his subs than you are. like previously stated, if you want a low-dollar powerhouse amp, get the jbl.

LMAO! ok thats the best coment yet on them. I just bought them because they were there, infront of me, and I wanted to try something new. *srugs* oh well live and learn.. but my plan is to install them in a box made to look for show then sell them off, probably to someone who wants something for show, not comp, just show off to friends stuff.

Your Sony headunit probably puts out about 13-15 watts a channel RMS. The 50x4 is the max rating that the cooperations put on there products to make them seem better to people who don't know any better. Example: "This new state-of-the-art exhaust system with give a 55hp increase" when it just gives you a 5hp increase. Its all marketing.
