I have a f90bt in a 2007 Toyota Sienna with the 10 speaker JBL system (9.1 in reality). The factory amp leaves a lot to be desired, the 3.5s in the back are just absolutely awful. Does anyone know what size amp I should run and how many channels this system would need to get the most out of it.

 

1. How many channels?

2. How many total watts/watts per channel?

3. Anything else I should look for?

 

Thanks all

If you're going to be add an amp then you might as well replace the crappy speakers. you can get a 4 ch amp and get a new set of 2 fronts and 2 rears or get a 5ch amp where the last one would be for a subwoofer.

 

i suggest getting a nice component set up in front and some mediocore stuff for the rear to fill. and a simple 10" woofer.
