Proper way to run 4 speaker off front channel?

[Impact9]

I'm going to have a extra set of Polks db5250 and I want to install them in the kick panels via Q-Forms. What I use to do nearly a decade ago was use a RCA splitter to split the signal between 2 amps. Is that the proper way still or is there a better way? :confused:

Thanks!

how about using one amp and wiring them 2 ohm stereo?

If youre talking about running 4 speakers up front, Id recommend against it. One set is all you need up there.

Yea I was hoping to add more mid bass. Guess the wife gets my set then. :( :rolleyes:

if youre wanting to add more midbass, id get a midbass driver and put it in the door, then put your speakers now in the q-forms

any recommendations? Also do I just use a RCA splitter here since I already am using my front, rear, and sub RCA outputs? I need to stay under 6 1/2". Don't really want to cut my doors.
