This Is A Short List Of Our Most Frequently Asked Questions

We always recommend using a professional that has
experience in tuning amplifiers because this is vital to the quality and longevity of your entire system and needs to be done correctly.

Clipping is distortion generally introduced by improper tuning or volume control. Clipping means you are damaging your amplifier or speakers and continuing to do so may destroy them. Generally, all our amps have clipping indicators built in so you can see if you are clipping or not. Tuning your amp to no clipping will ensure long life and great sound.

Popping subs can mean there is an issue with your subwoofer or box. If the box is very out of specification, there will be very little cone control which will make a popping sound.

Another issue could be that a wire it is hitting the cone and making the sound.

It could also be a blown or defective voice coil. A good way to tell is to smell the woofer. If it smells like anti lock brakes the voice coil may be burned. You can also place the sub on the ground and push in the cone slightly to see if you hear any scratching or rubbing as a working sub will have no sounds or rubbing.

You can reset your amp by powering down the amp or disconnecting the remote wire. If the amp continues to go into protection, please contact for trouble shooting or start your warranty here:

How do I break in my subwoofer?

It usually takes anywhere from a few days to a few weeks to break in a sub.  Its good to play low to mid volume for the first two days then give it full power after that. As the speaker plays, the suspension will loosen or “break in” which is natural and what is normal for all subs.

What is the difference between a dual 4-ohm voice coil and dual 2 ohm voice coil?

Ohms are the resistance of speakers. The most popular
speaker choice is single 4 ohm or dual 4 ohm (D4). D4 Dual 4-ohm is typical for subs and single - ohm is typical of most midranges and tweeters.

The goal is to match the recommended impedance of your subs or speakers to the optimum impedance of your amp.

Using 2 subs you generally want Dual 4-ohm coils on both subs wired in parallel to a Monoblock amp. For one sub dual 2-ohm coils all wired in parallel to a Monoblock amp.  However, with different coils configurations, different amps and different subs can be used to obtain the closest impedance match you can get for the loudest sound.
