(2) 3 ohm voicecoils wired in parallel net a 1.75 ohm impedence.
The amplifier will produce 2000W 1 ohm
1500W @ 2 ohm.
A 1.75 Ohm load will be somewhere inbetween.
Plan on 1750W.
Plenty of power for both in the proper enclosure.

    Add up the fuses on the amplifiers to get your peak current draw.

    Add 30-35A for normal usage by the car.

    130A usually would do the trick.

    Ohio Generator makes stock replacements with pulley alterations and upgraded assemblies for reasonable prices.

How can i connect 2 12''s pioneer premier too an jl audio amp n make the bass loud???


Hello m1k377060,

Having your subs in well-designed and constructed enclosures will make as much or more difference in their output than how you connect them to an amp.

The TS-SW1241D's are single voice coil 4 ohm shallow subwoofers that are rated for 350 watts RMS. For maximum loudness, your JL amp needs to be 2 ohm stable and capable of delivering 700 watts RMS into that impedance. Wire the subs in parallel for a 2 ohm load and maximum power from the amp.

Hope this helps.

JL audio 250/1 not powerful enough for pioneer TS-W307D4?

Hi, will i be able to feed 2 JL Audio 12W7s with 1 Pioneer PRS-D2000SPL amp? thanks


Yes, that should have enough power. Remember to use 8 or 10 gauge wire to in stall amp, and 14 gauge for the speakers.

Jl amp


If the power supply feeding the amp is OK, it should have blown the fuse well before the voltage dropped to 5v. What size/type fuse do you have in the power wire feeding the amp?

This sounds like an amplifier that trying to push a lower impedance load than its supposed to. Typical aftermarket car speakers have a 4ohm reading per voicecoil. By running more than one speaker per channel you can get more power(sometimes alot more) from the amp by feeding it a 2ohm load or more. If the amp isn't designed to handle ratings less than 4ohms a channel it will overheat and shutdown.

Lights dim


3000 watts divided by 12 volts=267 amps...how hot is your alternator...have you considered a separate alternator or a battery isolator?
