Amp is on, but sub wont produce any bass

The bus connection is actually not an RCA looks very, similar i think if you look at it it will say IN. as far as i remember its an input for like a CD changer. Run a Y splitter on one of the other RCA out put, split the signal and run one to your bass amp. it does not affect the voltage in the RCA signal. i think your amp is trying to send a signal instead of receiving one.

have you tryed wiring it strait and regrounding it ?

On the amp there should be High pass and a low pass setting. Put it on low pass cause if its on high pass or in between it produces normal noted like a speaker. Low pass will filter out all the high frequencies.

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.

Those 12's Need to be in a Ported Inclosure to release the Air that the Bass Produces. Use a 1 Inch Key Hole Bit and make 1 Hole at the Top Corner of Each Portion of the Box. Top Left and Top Right. Please Rate My Response! Thanks!

This one Wire should be for the +. Try connecting the + to the Head Unit and - to a Common Ground. At the Worst, You will Blow the Amp Fuse if not Correct. The Lead from the Head Unit is Only an Off and On from the Ignition. Please Rate My Response! Thanks!

Did you check to make sure that you didn't blow a channel in the amp? Another thing to check would be the connection on the inside of your box, maybe there is just a wire loose.

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS

First of all how many ohm's are each subwoofer rated at . Are the subwoofers dual voice coil or single voice coil. Once I know that I can help you. I think the JL amp is not recommended below a 2ohm load.

The first thing to try is disconnecting ONE of the two subs. See if you get more bass with a single sub than with both. If you do, re-connect the second subwoofer, but reverse the (+) and (-) wires.
