Disclaimer: This page is just suggestions for amps I believe are of high quality and will provide a good sound when used with a Toby Speaker Cabinet.
We have NO CONTROL over the way that your amplifier has been set or the way it was installed. Therefore, TobyCorp offers No Guarantee that  
while using one of these amplifiers you will not have a problem with burning up one of our drivers. Professional Installation and Setting of your amp
is Definitely recommended and may minimize problems. Any of these amps may give you issues IF SET IMPROPERLY with the gain too high or 
improperly set crossover points.       
         
TobyCorp recommends Never using a "Bass Boost" function of an amplifier, or the ever so popular "Bass Knob" which 
controls the boost setting. Our cabinets are engineered for optimal clarity and volume without the use of this function.
Always use the "Gain" knob on an amplifier to set it's loudness. This only adjusts the actual VOLUME instead of changing the speakers Freq. Response.
         
Crossover point for our subs should be set to approx. 110Hz on the "Low pass" setting.
