The SPX-i and XP have temp sensing modules in them to prevent the rectifiers from frying.

 

You won't get that feature from the other high output companies most typically ran.

You get what you pay for.

 

People run extra power cable as well as ground cable for this reason only-

Unlike other uses in the electrical world, for car audio, because of it's low voltage operation, more cabling is required not because to support the current, but to prevent voltage drop as much as possible.

 

Most DC products only have a 5-6v window.

 

Look at AC, many products in AC ran in the house may have a window of 40v or more which isn't as crucial for tons of wiring.
