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

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?


you should move up to more power....underpowering subs is bad! try not to go under the subs rms by 5o watts?

Bass freezes at a certain volumn and no longer gets higher


JUST CHECK THE CROSSOVER SWITCH, AND MAKE SURE THE SWITCHES ARE IN THE CORRECT POSITIONS

(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.

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.

The specs I read on the Pioneer site say the amp is not 1 ohm stable, so keep that in mind.

It partially depends on the impedance of each voice coil on the DVC subs. If they are dual 4 ohm, and you connect the DVCs in parallel ("+"s together, "-"s together), you could run a sub on each channel of the amp(s). This would put about 200W on each sub.

The other option is to still tie the dual 4 ohm voice coils in parallel, tie 2 subs in series (one "+" to the other "-"), and bridge the two channels of the amp (aka put them in parallel). But this, also, would be about 200W on each sub.

Things get different if the subs have dual 2 ohm, 3 ohm, or 8 ohm voice coils.

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?
