IMPEDANCE VS FREQUENCY

FEATURES

If you have this in your hand, you have taken the next step. You’ve entered a world of NO COMPROMISES with a subwoofer that will take your car audio to a whole new level. So get out there and shake the foundation to its core! Show them that true dedication comes from the inside of your trunk and that “good enough” never will be enough.
THIS IS WHAT REAL BASS FEELS LIKE
A MAX subwoofer is designed to test the limits and match your dedication in performance and style. To be able to withstand the extreme conditions you surely will put this subwoofer through, the cone is made of non-pressed paper with Mica minerals that excellently balances awesome power, weight and musicality. To handle all of this beautiful bass, we’ve implemented a T-bone basket that holds vibrations at bay and adds extra stability for the larger models (12” & 15”).
TRULY NEXT LEVEL
The dust cap is made of IMPP, an idea we borrowed from the MAD S2 series. But since this is MAX, we took it one step further and reinforced it with ﬁbers. It’ll handle everything you throw at it! The impressive high roll ribbon foam suspension gives you even more awesome cone movement. This cone is simply made to move! The 3-inch dual black coated BASV voice coil wire is made of PCW (Pure Copper Wire) and will make sure the subwoofer handles both an insane amount of power and heat. To give you an unmatched connection, we’ve added four 6mm² pure OFC copper (direct tinsel terminated) speaker cables instead of old fashioned terminals.
IMPRESSIVE IN EVERY SINGLE WAY
The MAX S2 series will make jaws drop. We show our dedication to the craft of bass with triple stacked HQ ferrite magnets to achieve a truly mind-blowing amount of motor in the subwoofer. We’ve added a Dual Nomex spider with orange mesh technology and dual stitching for extra durability, to make sure that the last thing standing will be your sound system. Is this enough for you? We doubt it. To add even more durability and ﬂexibility we’ve added a woven web to the spider, for extra strength and style!
COOL UNDER PRESSURE
The MAX S2 will show everyone that you have reached the next level, the MAX level. Having a subwoofer perform at this level demands extremely good ventilation. Only the best and beyond is good enough! We solved the cooling in two different ways. The material in the top/back plate is thicker for optimal heat conduction, and the implemented DVS2 (Dual Ventilation System) creates incredible heat dissipation while also reducing distortion.

HOW TO

INSTALL SUBWOOFER
Before installing your brand new subwoofer, make sure that you have everything you need. Have the right tools ready, and make sure that you have the necessary knowledge/skill to perform the installation properly. Preparation and knowledge is crucial!
The MAX S2-10D1/S2-12D1/S2-15D1 uses dual 1 Ohm voice coils, while the MAX S2-10D2 /S2-12D2/S2-15D2 uses dual 2 Ohm voice coils. If you want to connect two or more S2 series sub- woofers, you can vary the impedance by altering the wiring conﬁguration to use a series, parallel or series-parallel setup. The more the merrier!
Make sure to look through the recommended wiring schematics below and choose the setup that corresponds with the number of subwoofers in your sound system. Take note of the impedance stability of your ampliﬁer. Don’t be afraid to consult your local GAS AUDIO POWER dealer/installer if you have any questions.
It is important to know the limits of your ampliﬁer. Be sure to connect your sound system with a suitable impedance to optimize your sound system.

It is important to know the limits of your ampliﬁer. Be sure to connect your sound system with a suitable impedance to optimize your sound system.
BUILD ENCLOSURE
If you want a LOUD and awesome looking sound system, you should mount your MAX subwoofer in an enclosure. Here’s information about optimized volumes for different types of enclosures and how they perform with the MAX S2 subwoofer. If you feel unsure about how to build an enclosure on your own, consult a local GAS AUDIO POWER dealer/installer.

DO I NEED POLYFILL?
Hell yeah! We recommend using polyﬁll for all sealed, vented and bandpass enclosures for the best overall performance.
A polyﬁlled enclosure will bring out the full potential of your subwoofer, by starting an isothermal process when energy ﬂows through the ﬁbers (very scientiﬁc). This means that the air gets more dense, so it lessens the BOOM and brings out the BASS! It can also reduce harmonic distortion. Sounds complicated, we know. But it’s easy to do! Cover two sides in a ported enclosure or make a loose polyﬁll ball behind the driver in a sealed enclosure. Try it out! If you like the bass to hit harder – just take away some. Do you want to lessen the effect? Put in some more.

TROUBLESHOOTING

NO POWER/SOUND
Check the subwoofer to make sure it isn’t damaged. If your subwoofer doesn’t get any power, the most common issue is either in the wiring or in the ampliﬁer. Use a multimeter to measure the ampliﬁer’s voltage on the +12V terminal and the remote signal terminal. Use a multimeter to make sure that you have a negative ground connection. Check the built-in fuse (if there’s one) on the ampliﬁer. If there’s no power coming through – control the fuse on the power cable. If this is intact – make a full check of the wiring to ensure cable integrity.
Check all the speakers connected to your sound system. Check all the speaker cables and all the signal cables. Check your head unit to make sure no settings are limiting the ampliﬁer’s functions or the subwoofer. When all of the above has been tested/looked over, and all is as it should be but there’s still no sound, consult your local GAS dealer.
UNWANTED NOISE
Start by looking over the subwoofer and other speakers in the sound system so there is no damage or connection issue with the wiring. Make sure that your signal cables or speaker cables aren’t too close to the power cables. Check your ampliﬁer’s grounding point and make sure that the surface is clean. When all of the above has been tested/looked over, and the unwanted noise does not vanish, consult your local GAS dealer
DISTORTION
Start by looking over the subwoofer and other speakers in the sound system so there’s no damage or connection issue with the wiring. Check the speaker cables to make sure that the polarity isn’t reversed on one channel. Check the settings on the ampliﬁer, make sure that the gain/level is set according to the ampliﬁer’s instructions. If your ampliﬁer has a boost function, lower its effect or turn it off.
