0.6 cu ft per driver is awfully small for those subs. The polyfill may help, but I doubt it's going to make the subs feel like they're in a box 2x the size. It's sounding more and more like you may have the wrong subs for the situation. You may want to see about getting some different speakers (10's maybe?) that are tuned for a smaller box and 4 ohms each.

What's the best way to hook up my jl audio 13" w 7 sub to my jl audio 1000/1 amp


the best way? hmm. i would start off with some wire. Keep in mind that you will need to separate the positive (usually red or has a stripe or marking on it) from the negative (Black usually is the common color for this wire) and hook the up according to your amps positive and negative hook ups / terminals following your sub-woofers terminals. then depending on your sub woofers Voice coils (Duel or single voice coils) yours are duel or quad coils but i\'m sure they are duel (2 of each positive and negative equaling a total of 4 posts on each sub-woofer). figure out your amps ohm load handling and does your amp run hot (1,2 or 4 ohm stable some are even less like 0.5 or lower) i would run at a 1 or 2 ohm load as that is usually standard on 1 channel amps. make sure to check your wiring and if your not sure about ohm loads just Google wiring for sub-woofer ohm loads such as 0.5 ohm, 1 ohm, 2 ohm or 4 ohm loads. also make sure your box is not sealed do to the fact they are siht and cant produce sound like a vented / ported enclosure keep the size as big as you can fit in your car or truck the bigger the better. i had one 8\'\' sony sub pounding like a 15\'\' sub real loud . Also MDF particle board is garbage it causes port noise and absorbs water

My behringer pmp3000 doesn't seem to have much power to use my two peavey 12" speakers and use a mic. I have to push the gain and faders up more than I think I should have to, to get a decent level of...


Where do you have the gain control set on the Mic channel ?
If you have no issues with either the speakers or the Mic, and the gain control for the channel you have the Mic plugged into is set at a somewhat "normal" position, you might have a problem with the mixer itself.

Amps turn off and cut out


You just gotta get your gains set up right. Look Up "How To Set your Gains with a Multimeter" your over powering your subs or speakers and your amplifiers cant keep up. you also have to make sure your speakers are wired to the right ohms. your amp cant handle. if your amp cant handle, for Example:1 Ohms your gonna blow your amps. ......Speakers and subs are a science too.

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.

Knocking noise with my kicker compvr 15"


comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.

Alpine pdx 1.1000 amp


These subs are dual voice coil I'm sure...make sure they are putting a 2 ohm load on the amp total, and also set your gain and frequency setting right. Set the frequency around 85 or 90, make sure the lo pass filter is on. Turn the gain ALL the way down and turn your stereo to the point right before your speakers distort....then slowly increase the gain until the subs are playing at full volume. This should not even be close to all the way up, and the subs should sound accurate and bold. Turning them past this point will cause distortion, in which case you should back off the gain a bit. Distortion causes power to cycle through the amp very rapidly and can cause blown subs and blown fuses. If you do not know how to wire both subs for a combined load of 2 ohms, please let me know what type of subs you have.
