I assume I could use this to connect a 2 channel amp to my HK head unit by cutting the speaker outs and splicing into the SNI-35 harness?

If I use an amp can I install 4 Ohm speakers with the 2 Ohm HK head unit?

You can cut or make adaptors to plug into the ends of the stock wires.


Once you add an amp, the impedance of the radio isn't used to determine speakers. You use the impedance of the amp

 

Thanks!

 

most amps these days have both high level (speaker wire) and low level (RCA) inputs. You can use either or but not both on the same amp. I would suggest a PAC SNI-15 instead of the 35. The 15 is a direct 10:1 reduction whereas the 35 is variable and can be a pain to dial in with your gains also.

I was wondering about that, wouldn't you want to turn down the gains on the SNI-35 and just use the ones on the amp?

Jim

 

you won't want to turn them down, just leave them set as they are from the factory. The PAC adjustable adapters are set at 10:1 reduction which is pretty much widely used across the industry for these line level adapters.

 

Got this off the PAC website...

SNI-35 converts 2 to 40 watts per channel speaker level output into a pre-amp signal. Perfect when adding an amplifier to a factory or aftermarket radio. Great for getting an additional set of pre-amps outputs from a head unit equipped with only one set. • Fixed 10:1 conversion.
• Linear from 20-20,000Hz at +/- 5 dB, while maintaining signal phase.
• Isolates input and output circuits to prevent ground loop noise.

so any recommendations regarding the gain settings on the PAC-35....and how do the gains on the PAC affect setting the gains on the amp when using the test tone and a multimeter?

Jim

 

the key here is +/- 5db. If you leave it set in the middle, it's at 0db. Set it at 12 oclock and leave it there.

 

Thank you Sir!
