Amp Configuration

[Cpan13]

I'll be doing a stereo overhaul in my G21 this spring and trying to figure out if in need to buy another amp or how I can power it all with what I have already. (I won't be doing the install. Just want to have everything ready for the pro.)

Speakers
4x Rev 10s for tower
6x Revo 8 in boats

Subs
1x XS12
1x 15" Fi Audio IB3

Amps
1x Syn4
2x Syn6

So I'm wondering if I should pick up another Syn4 and run each set of tower speakers off 2 syn 4s and then the inboats and subs each on syn 6s or if I can get away with the 3 amps I have already.

SVC or DVC 2 or 4 ohm? and whats its RMS

6x Revo 8 in boats

Use one of the Syn-6 here

Rather than another Syn-4, trade up to a Syn-DX2.3HP to drive all four.
