Prob should have looked into this before I droped the cash on 6 speakers and 2 amps but how do I go about wiring a PBR300x4 and a PBR300x2 into my factory HK radio that only has the 2 front speaker outputs ?

 

Look in the Audio section, or ask ULTRANUTZ

 

ill send you a pm, ultranutz sent me explained alot for me

 

Use the two channels out from your radio to power the high level inputs on both amps.

What speakers do you plan on using with the pbr300x4?

 

Polk audio, can't remember if its DXI or DBI

 

The Polk DB series is only good for 60 watts. The MM series are good to 100 watts.

 

I have (4) DXi650 and (2) Rockford Fosgate P1692

 

The pbr300x4 amp is only good for 4 ohm speakers. He can't use the MM series speakers with it.

 

Doesn't matter. They are kissing cousin's.

 

The rear outputs from the radio are active, you just need to connect them and flash the radio for fade control if you want fade.
No flash needed for the rear speaker out.
