Hello,

I have a Pioneer AVH X2790bt head, and a Pioneer TS W304R 1200 Watt Sub. I also have a Sony XM N 502 amp (2 Channel). With these I have 4 low end Boston acoustic speakers.

Ive upgraded my speakers to Polk DB 6501 for the fronts, and Polk DB501 for rears, as I can fit only 5.25 inch speakers in the rear. I have also bought a Sony XM N 1004 (4 Channel amp)

The config of the amp are:
1,000 W high power output
70 W x 4 (4 ohms), 85 W x 4 (2 ohms), 175 W x 2 (BTL)

CHANNEL CONFIGURATION
4ch;3ch;2ch
MAX. CHANNEL POWER CONFIGURATION AT 4 OHM
4 x 170 W
MAX. CHANNEL CONFIGURATION AT 4 OHM BTL
2 x 500 W
MAX. CHANNEL POWER CONFIGURATION AT 2 OHM
4 x 250 W
FREQUENCY RESPONSE
5–50 kHz

To get the best of the system, can I connect my Polks x 4 speakers (DB 6501 Front and DB 501) and the Sub to the 4 Channel amp?

Or

Is it best that I have two amps in the car, (I already have the Sony 2 channel XM N 502 amp installed) and run the Pioneer Sub via the 2 channel as it is configuured now, and have the Polks running off the 4 Channel amp?

Since I live in India, a third world country for eternity, and almost evereyone is very happy with super low end OEM audio in their cars, I have limited options. A 5 channel amp cannot be found here within my budget

Thanks very much for you time.
