Most modern vehicles operate using a standard lead acid battery of many different shapes and sizes. Follow the link to view a chart of ideal Deep Cycle Batteries to choose from or contact us to learn about the best options for your specific vehicle and application.

Every vehicle is different in the way they adapt a new aftermarket stereo. The best route here is to bring the vehicle to LIS Audio and have our experts evaluate it and your preferences for the installation.

The Big 3 Upgrade is additional wiring added to the factory electrical system to help deliver more electrical current to the vehicle's factory and aftermarket components. Follow the link to learn more in detail what the Big 3 Upgrade is and it's benefits.

A high output alternator is an upgraded or aftermarket alternator that offers more potential amperage than the factory alternator.

The legal window tint percentage in the state of Kansas in 2017 is 35% on all windows except the front windshield.

The legal window tint percentage in the state of Missouri is 35% on the front driver and passenger windows and nothing on the front windshield. The rest the vehicle can be tinted as low as the driver prefers.

If the vehicle has an efficient enough alternator for the application, the Big 3 Upgrade performed and a healthy battery than the amplifier should have enough on board capacitance to have no need for an inline power cap. In nontraditional fashion a power capacitor can be very beneficial in the engine bay placed inline between the alternator and battery, this addition can help smooth out the ripple delivered battery causing much less noise in the audio system.

When an audio manufacturer prints the Max or Peak wattage on the box it is often exaggerated. If the Max or Peak wattage is ever met it is most likely in near perfect laboratory like conditions, which will never be matched in a day to day vehicle.

One of the most accurate tools to use when setting amplifier gain or input sensitivity is an Oscilloscope. Using a test tone track and testing the output signal of the source unit all the way back to the input signal of the amp to maximize it to the point of just under distortion. The DD-1 is also another easy tool used for setting input sensitivity.

The gauge of wire is typically determined by the amount of power to be run factored against the length of the run from the battery to the amplifier. Follow the link to view a small graph showing typical power ratings and vehicle power wire run lengths.

The tuning of a custom subwoofer enclosure is all about the inner air volume ratio against the port volume. Using the specifications of any subwoofer to design a custom enclosure is most ideal for any sub-stage application, if possible. Read more about LIS Audio custom enclosures to learn more.

Yes and No. In the state of Kansas the laws on underglow and interior lighting vary from county to county.

There are two definitions to clipping in the audio industry. One definition pertains to the shape of the sine wave when the speaker is being play, the second is when the amplifier approaches it's maximum performance and begins to put itself into power protection.

Just as when the sine wave distorts and begins to flatten out due to distortion, this happens in an a more audible and physical manner with a speaker is subwoofer. Most of the time in the form of voice cool rub, bottoming out or a change in the audible sound the subwoofer produces.
