No charge will be made to the consumer for either parts or labour in repairing or replacing   the product. All replaced parts and cosmetic parts should be free of defects at the time of shipment and, therefore shall not be covered under these limited warranty terms.
• Repaired product will be warranted for the balance of the original warranty period or for ninety (90) days from the date of repair, whichever is longer.
• All warranty claims must be accompanied with a copy of this warranty card, and a copy of proof of purchase date.

The consumer shall have no coverage or benefits under this limited warranty if any of the following conditions are applicable:

• The product has been subject to: abnormal use, abnormal conditions, improper storage, exposure to   excessive moisture or dampness, exposure to excessive temperature or other such environmental conditions, unauthorised modifications, unauthorised connections, unauthorised repair including but not limited to use of unauthorised spare parts in repairs, misuse, neglect, abuse, accident, alteration, improper installation, acts of God, spill of foods or liquids, maladjustment of customer controls or other   acts which are beyond the reasonable control of FUSION, including deficiencies in consumable parts such as fuses, and breakage or damage to antennae unless caused directly by defects in materials or workmanship, and normal wear and tear of the product.
• FUSION was not notified by the consumer of the alleged defect or malfunction of the product during the applicable limited warranty period.
• The product serial number or the accessory date code has been removed, defaced or altered.
• The product was used with or connected to an accessory not supplied by FUSION or fit for use with FUSION product, or used in a manner other than its intended use.

If a problem develops during the limited warranty period, the consumer should take the following step-by-step procedure:
1.The consumer shall return the product to the place of purchase for repair or replacement processing.
2.The consumer shall also be charged for any parts or labour charges not covered by this limited warranty. The consumer shall be responsible for expenses related to
reinstallation of the product.
3.If the product is returned to FUSION after the expiration of the warranty period, FUSION’s normal service policies shall apply   and the consumer will be charged accordingly.

TO THE EXTENT PERMITTED BY LAW, FUSION SHALL NOT BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OR A LOSS OF ANTICIPATED BENEFITS OR PROFITS, OUT OF USE OR INABILITY TO USE THE PRODUCT.

• Some states in America do not allow the exclusion or limitation of consequential damages, so the above limitation and exclusion may not apply to you. This warranty gives you specific legal rights which may vary from state to state.
• FUSION neither assumes nor authorises any authorised service centre or any person or entity to assume for it any other obligation or liability beyond that which is expressly provided for in this warranty.
• All warranty information, product features and specifications are subject to change without notice.

Some Mono block (single channel) amplifiers have 4 speaker output  terminals as shown below. These are internally linked Positive together and Negative together, this is to make connection to multi coil Subwoofers easier when you configure in parallel. You can connect each coil directly to the terminals (one per side) rather than at the subwoofer. 

This happens as a result of your amplifier trying to draw as much current (amps ) as it can to produce large/loud  bass notes, low frequency notes  are the biggest culprit. In some cases the Alternator is unable to supply enough to the amp and other devices. As a result of this other devices may not function correctly like headlight etc. You need to ensure that  your alternator is providing the correct Amperage  or it may need replacing or reconditioning. Apply a load test to your battery to ensure it is in good working condition.  Do not assume that adding a capacitor or a second  battery will solve the problem  because if the alternator is not providing enough Amperage it will only solve it temporarily. Investigate a higher output alternator. 

The Inline fuse should be fitted as close to the battery as possible and the rating (amperage) the same or higher than the total on board fusing of your Amplifier. This fuse is to protect the power cable from  grounding and potentially starting a fire. 

This could be happening if you have selected 4 channel  on the Input selection switch but have only 2 channels connected. The input selector must be set to the  correct  position.  If 2 channel is selected (with 2 channels connected) the output is supplied to all 4 output channels and if 4 channels are connected but 2 channels are selected you will only get 2 output channels.  For more information contact us at Tech Email

    My speakers are 300 watts “MAX” and 90 watts “Rated Power” what size amp     
    do I need to drive them to achieve the best performance.  
  
 

 . When you are choosing an amplifier to drive speakers or a Subwoofer you should  
    use the “RMS” per channel ratings(Amplifier) and the “Rated Power”

   (Speaker/Subwoofer) as the reference for your choice. Always define which
    ratings you are comparing and try and get them as close as you can.                                                                                                     

    “Max/Peak” Power Rating
    The “MAX/PEAK” power rating of a speaker is the amount of power
    that the speaker can handle in short bursts or peaks without causing
    permanent damage to the voice coil.If this rating is exceeded constantly
    you will risk burning the voice coil.
 
     “Rated Power” Power Rating  
     The “Rated Power” rating of the speaker is generally considered to be the
     nominal constant power that the speaker will handle continuously
     without causing damage.
 
     Therefore if your speakers are rated at 90 watts (Rated Power) you should drive   
     them with an amplifier that is capable of supplying 90 watts RMS per
     Channel or as close to that as possible. That is not to say that an amp
     capable of a higher output cannot be used if the amplifier settings are
     managed responsibly realising the potential to overdrive your speakers
     exists. This rule also applies to using an amplifier that is under driving
     your speakers. Constantly driving a distorted signal from an overdriven  
     Source to your speakers can cause damage to the voice coils
 

Bridge mode is commonly used to get more output power from amplifiers by combining two single channels output into one output. This can only be done safely if you know the minimum load (Ohms) permissible when bridged. This is more common when driving Subwoofers that have Dual voice coils or when you have multiple Subwoofers. First check the installation manual or look at the speaker  terminal block on the amplifier as they normally have a diagram showing the bridged connections.

This is an example of a 4 channel amp speaker connection terminal block. As shown bridging is achieved by connecting the positive terminal from the left channel and the negative terminal of the right channel to the corresponding terminals on the subwoofer coil or coils depending on configuration. There are a number of different configurations depending on the load applied to the amplifier. See Subwoofer coil configuration.  It all depends on whether you have a  4 Ohm, 2 Ohm or 1 Ohm stable amplifier (mono). An example of the different power ratings for a four channel amplifier  are as follows.

100 Watts RMS x 4 @ 4 Ohms
200 Watts RMS x 2 Bridged @ 2 Ohms

These are examples only to give you an idea how this works. This also applies for  2 channel amplifiers and  depends on whether they  class AB or  D class amps as the 1 Ohm rating applies to D class amps in general.
