Subwoofer not getting max bass

It sounds like your amplifier may be clipping, which can cause distortion and eventually damage your subwoofers. This can happen if you turn the gain or bass boost too high, or if you are pushing the amp beyond its rated power.
Here are a few things you can try:

1. Check the wiring: Make sure that the positive and negative speaker wires are securely connected to the amplifier and the subwoofers, and that there are no loose or damaged connections.
2. Adjust the gain: Turn down the gain on the amplifier to reduce the amount of power being sent to the subwoofers. Start with a low setting and gradually increase it until the subs are playing at a comfortable volume.
3. Check the bass boost: If your amplifier has a bass boost feature, turn it off or reduce it to a low setting. This can also cause the amplifier to clip and damage the subs.
4. Check the impedance: Make sure that the subwoofers are wired to the correct impedance for your amplifier. Wiring them incorrectly can cause the amp to overheat and shut off.

If none of these solutions work, you may need to have your amplifier and subwoofers checked by a professional.

Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.)

Yes, technically you can, however you will be putting both your sub and your amp at risk. One of the worst things you can do to a sub is underpower it. The easiest way to explain it is n ot giving enough power to the sub leaves it starving for power. The motor structure ends up working too hard to try and move the cone properly and what happens is the sub will usually seize up rather than blowing out in the term you usually hear (ie, I had my system cranked up and I blew my subwoofer).

Secondly, in an attempt to get any real sound out of the under powered sub, you'll probably end up cranking the gain and bass boost on the amp which ends up overworking the amplifier quite a bit and can in turn lead to fried out amp chips, burnt up circuit boards etc.

Thirdly, by maxing the gain bass boost you're going to end sending a lot of distortion through your subwoofer in an attempt to get some decent bass. Distortion kills both subwoofers and speakers alike.

So to answer your question, yes you can hook up your subwoofer to that amp and yes, it will probably play for a while but I wouldn't recommend it. Look for a class d or mono block amp to push your sub as these will give you the most power and best heat dissipation. They are designed to push subwoofers specifically and you will get better sound and longer life out of your equipment. A good rule of thumb is look for an amp within 100-150 watts of both your RMS power handling and your Peak power. Remember, when it doubt, always go a little bigger on the amp side of the spectrum. It's easy to "tune down" an amp by having the gain and bass boost at a lower level (50%, 25% etc), than to turn 'em all the way up just to get some bass and end up prematurely blowing out your sub, amp or even worse, both.

what product brand did you install. do you set the amps x-over and gains a sub sonic filter right
need to see if the amp is on check led light on amp. make sure your subs ohm load is correct for the amp.

let us an example fake amp 500x2channel max output 1000watts

if you wire your subs at 4 ohms you 250x2 rms stereo
if you wire your subs at 2 ohms you 500x2 rms stereo
if you wire your subs at 4 ohm mono you get 1000 watts

if you have the input voltage of 14.4 all the time at the amp

whats the equipment power

What do you mean that it sometimes doesn't work? It doesn't power on automatically?
Check settings of your receiver - if it has subwoofer output enables and if low frequencies from all channels are directed also to the SUB. By default only the LFE channel (.1) of 5.1 signal input is fed to the subwoofer. So Sub will work in this case only when you listen to 5.1 signal (DVD movie for example), but for radio or stereo music, only front speakers are used. By configuring this bass redirect, you can use subwoofer for all signal types.

Just get a 12" sub box enclosure for an audio store near you or make a custom box, a larger box supposedly gives you more bass yet at the cost of boot space. I have a type R sub and the box is only as big as it needs to be for the sub to fit and it gives amazing bass.

Bridge it. Should be marked on amp. According to specs should get u the power u need. Amp max 1500 watts. at 2 ohms. Speaker max is 2200 watts at 4 ohms. Turn amp down and adjust to your own taste. trust your ear man.

Max 200 W. You could bridge 2 channels of a 4 channel amp (or get a 2 ch amp and bridge it) and connect the sub. Bridging = connect + of sub to + of one channel, and connect - of sub to - of *other* channel. Check amp manual for instructions.

Don't get a mono - most are 300W or more - might burn the coil during loud passages.

did you check your subwoofer? test your (speaker)subwoofer, maybe you need to replace it. ^_^

Hi JJerky,

I suggest we go for 2 ohm to preserve the amp and not heat things up so bad.
Your Subs are Dual Voice Coil(DVC) and 2 ohms each coil. I am going to tell you the wiring to insure you get balanced response from both Subs. We will wire the Subs Voice coils in Parallel to make them 1 ohm each. Then we will wire the Amp to the subs in series to make the total load on the amp 2 ohms. When you have series to both subs each sub gets the same current.


Example of my coding :SUB1VC1+ = Subwoofer 1 Voice Coil 1 Postive terminal.

SUB1VC1+ to SUB1VC2+
SUB1VC1 - to SUB1VC2-

SUB2VC1 + to SUB2VC2 +
SUB2VC1 - to SUB2VC2 -

AMP + to SUB1VC1 +
SUB1VC1 - to SUB2VC1 +
SUB2VC1 - to AMP -

This should give you a good repsonse.

Adjust your Bass Gain down very low at first. Also cut you LPF to about 60 hz. Crank up the volume on a bass test Audio track, Adjust the Bass Gain up unitl you get distortion. The turn it back a little. This is proper setting for your Gain.
