Question about Jl Audio 250/1 Car Audio Amplifier

1 Answer

Output problem I am using this amplifier to power a pioneer champion series 12 inch subwoofer. It has 2 4 ohm voice coils, wired in parallel to get a 2 ohm load. I followed the users manual to set the voltage at 22,4 volts, which gives 250 watts at 2 ohms, and my sub was barely responding, so i turned on the gain to get between 40 and 50 volts, the equivalent of 1000 watts out of the 250/1 amp, and the subwoofer handeled it, but the amp was heating too much, and the input wasnt precisely reproduced. Should i consider a more powerful amp for my sub given that my subwoofer is rated at 400 W RMS? Can this amplifier handle a pioneer TS-W307D4 or TS-308D4 pioneer subwoofer (12 inch double voice coil 400 W rms) or should i go for a more powerful one???

    I was talking about rms power, since power=voltage*current
    the problem is with the jl amp's normal power i cant seem to get the pioneer sub moving...any help?

Dude TRUST me what you are using and have setup already is plenty..ONE TIP...of all things anyoine ever needs to worry about is the R...M....S power rating...the PEAK means NOTHING! its safe and fine to use what you got.

What kind amp should be use for ts-w307d2 subwoofer speaker?


Nice sub, i have 2 308d4s in my car. Okay this sub is a dual coil 2 ohm. so to get best bang for your buck you'll want a 2 channel amp and bridge it. Your sub is 400 watts RMS, So you'll want an amp that has the same rating. I'd recommend the pioneer GM-5400t. Then wire your voice coils in parallel, and bridge your amp, you'll get 380 watts RMS, which is perfect for this sub. If you have questions on wiring or anything you can just ask. thanks, i hope this helps

Wireing diagrams


Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

How do i wire two 15 inch subs to 2 ohms


Hello familia_gome,

Those MOFO-15's have dual 1ω voice coils. So the only way you can get 2 of them to present a 2ω load is to use 1 voice coil on each one with the two of them wired in series. Using both voice coils, you can get a 1/4ω load by wiring the voice coils in parallel and then wiring the subs themselves in parallel. You'll get a 1ω load with the voice coils in series and then parallel the subs. Or you'll get a 4ω load with both the voice coils and the subs in series.

Here's a link to Power Acoustik's PDF for the MOFO's. I recommend that you check out the wiring diagrams on page 3.

Hope this helps.

Subwoofers pop then immediately produce no sound


Sounds like the two subs wired together might be too much of a load on the amp and it is shutting off. Try wiring the two subs in series. That will reduce the load on the amp but will conversely put out less power. Less is better than none though. In any case check your amp to see what the lowest ohm rating it can see, that ohm rating is where you want your subs and if faced with a choice of either going under (lower numerically) or over (higher numerically) GO OVER!-it is much safer.
Here's an article I wrote that can help explain how to wire the subs to the amp.

OHM LOADS, SUB WIRING, OHM RELATED POWER OUTPUT

SERIES SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the negative pole of the other voice coil (on the same sub). This will leave you with a positive pole from one voice coil and a negative pole from the other giving you the two leads that will be hooked up to the amplifier or other subs. When wiring in series, the ohms will go up numerically, and the load on the amp will go down. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

PARALLEL SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the positive pole of the other voice coil (on the same sub). Then wire the negative to the negative in the same way. You can then wire to the amp or other subs. When wiring in parallel the ohms will go down numerically, and the load on the amp will go up. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

MULTIPLE SUBS USING SERIES AND PARALLEL WIRING
In order to match your amplifiers ohm rating you can use parallel and series wiring together, just keep things even for power distribution and to avoid phase issues.
Example: I have two “Type X 12” subs” that have dual 2ohm voice coils and have to match my “Amplifier X” ohm rating of 2ohms mono. In this case, I would wire each subwoofer in series (giving me a 4ohm load), and then wire the two subs in parallel to get my 2ohm mono load. When wiring multiple subs just, treat each sub as a voice coil and wire accordingly.

POWER OUTPUT AND OHM LOADS
For example if “Amplifier X” can make 100watts@8ohms, it would make 200watts@4ohms and 400watts@2ohms. However with every drop in ohms the amplifier is put under more pressure. It starts to create a lot of heat, distortion figures begin to climb, damping rates drop, and some amps even throw power spikes when clipping. SO BE SURE TO CHECK YOUR AMPS RATING AND DO NOT EXCEED IT!

I need instructions connecting my car subwoofers


Bridging your amplifier @ 4 ohm will yield the most power.... with the subwoofers you have.
You must wire them in Parallel.
Positive on both subwoofers to + on amplifier.
Negative on both subwoofers to - on amplifier.
The lowest impedence possible with 8 ohm woofers is 4 ohms.
