4 RCA pre-outs to 2 channel amp

I'm tryind to install my new Rockford Punch 2 channel amp to my Kenwood deck. the deck has 4 RCA pre-out wires, 2 red, 2 white. the amp only has 2 RCA plugs: one labeled left, one right. What goes where? I plan on running it bridged for my sub.

Also, I've heard that stuffing the sub box with polyfill "tricks" the sub into thinking it's in a bigger box, making it louder. However, does this also decreace the responce/sound quality?

Hi,

   The 4 RCA pre-out wires simply mean the Kenwood Deck is capable of controing two amps. I am curious, does this deck have sub woofer eq controls? I am not sure about the polyfill question.

i'm not sure about the sub eq control. I'll have to check when i get home.

So what you're saying is i only have to conect one red and one white? Or both red?

Filling the box is mostly used in order to compensate for a too small box. It might come in very handy If you are restricted in available space and still want to respect the desired / recommended enclosure size.

Besides giving the impression to the subwoofer that it is playing in a bigger box it has some other advantages :

- decrease / elimination of so called 'standing waves' will result in smoother / flattened frequency response

- slightly better efficiency (don't expect any miracles !)

When filling the box make sure the area directly behind the woofer cone stays free of filling material as

- the cone might come in contact with the filling

- the woofer might 'choke'

Do realize that you will have to experiment and measure a lot with the quantity of filling material before you will obtain the best result.  

Good luck !

Thanks for all the help guys. They are for front and rear (I actually cracked open the manual :P). The non-fading is only on the model above mine. Thanks again for all the help. Now I just have to do all the in-car wiring.

I do have one other question, but I'll put that in a new post. It should be close to this one.
