Rockford P2 vs DD600

[connerprince]

I have a brand new Toyota Corolla Cross and the speakers aren't putting out enough volume. My plan is to add an amp for the speakers, maybe replace the speakers or leave factory till they blow, and add a 12" sub, possibly with its own amp or do one 5ch amp for everything. I was looking at these two subs and either a 5 channel amp like the rockford one or two separate amps, one for speakers one for sub. Let me know what you think

Here are some opinions:

 

Get a separate amp for your sub, this has many many advantages,  the only advantage of using a single multichannel amp is when you want your install as simple as possible but otherwise not recommended.

 

As for the subs, there are many subs, you need to define your application and define your available space, your application can be for example, sound quality, low( like if you like rap and such music), loud, etc, space is also important, some subs like big boxes some can work in smaller boxes, some will work best in ported boxes and some in sealed. The only general advise when it comes to subs is do not get cheap $150 or so subs, those usually are good at nothing.
