Factory Sub Replacement is here!

[jasonconway5]

Just got my Polk Audio DB840dbc in the mail. I chose this unit for my factory sub replacement based on several reviews in this forum and others. My question is, do I make it 2 ohm or 4 ohm? which sounds better? How do I change it from dual 4 ohm to 2 ohm if 2 is better? im confused on how to wire it.

If it is a dual 4 Ohm sub wire both positive together and both negative together for a final 2 Ohm load.

If running off the stock amp then make it 2 ohms, if on a aftermarket then it depends on the amp.

Thanks, yeah that sounds much better

I don't think that factory amp will like that 2ohm load. I believe the factory sub is 4ohm?

Will this work in the console box or just the rear box?

No the factory amp is 2 ohms load. And this only fits the rear sub box

Is there a replacement for the front mounted sub?

I'm sure you could toss a 6" sub in there... I highly doubt it's going to do any good over the stock sub. My door speakers pump more bass the the stock sub did. But you are more than welcome to try. It may be enough of an upgrade for you. JL and kicker both make 6" subs as well as a handful of other companies. The key here is going to be finding a sub that has high efficiency and a high xmax.

Factory sub and amp are 2 ohm. Says 2 ohm on the magnet, but I tried it both ways and 2 ohm sounds best. Now I've got to do the rest of the speakers. Any suggestions? I paid $47 for the sub, just fyi on my spending range.
