What’s the difference between the BT2180.14 and the BT4180.14?
The main difference between these amplifiers is the number of speakers they can run, and the ability to fade sound between speakers.
(Explanation of fade: You might have experience fading sound between your car speakers. If your rear passengers wanted to listen to a song, but you wanted the music to be quiet in the front of the car, you sometimes have the ability to turn the volume down on the front speakers while simultaneously turning the volume up on the rear speakers. This is fading the music between the front and rear speakers.)
The BT2180.14 is a 2-channel amplifier and it can power four 4-ohm speakers wired in parallel. You will not be able to fade sound between the speakers.

The BT4180.14 is a 4-channel amplifier and it can power eight 4-ohm speakers. You will also be able to fade the sound between the speakers.

What’s the difference between the BT7P1.14 and the BT7P1 2014 Proline 7.1"?
The Pro’s are our top of the line speakers, built with even higher quality materials and construction than the BT7P1. If you had a high speed camera pointed at a speaker, you could see that all speakers physically distort when pushed to their max volume, causing sound distortion. The high quality construction of the Pro’s prevents this. These speakers are extremely effective at high volumes, handling 20% more volume than the BT7P1. They have more power handling capability, so they are best used with an aftermarket radio and amplifier that can supply that power. Both speaker types have open, clean and natural sound because of their paper cones.
