New Speakers - Polk DB6501?

Did you wire the tweeter too? The point of the crossover is to separate frequencies so the door speakers handles low end and tweeter handles only high end.

Check your amplifier settings to make sure if there are any crossover settings on it you have it set to through, let the Polk crossovers handle bass blocking and frequency handling. Check the radio too to make sure your RCAs aren't plugged into the sub out jacks. I know that seems obvious, but I've seen that mistake made.

Which amp did you end up getting? Just make sure your crossover is set correctly on the amp. Since you're running passive crossover, you can just disable the crossover on the amp and let the passive crossover deal with it.

It sounds like you might have your high crossover set pretty low, that's why you're only hearing bass and no mid or high.

Diagram shows correct wiring, provided all pos. and neg. are proper. Like others have said, check your rcas and your amps crossovers. It always comes back to something simple.

Thanks for all the replies!

I actually do have the RCA's going to the sub out jacks. Where am I suppose to put them? What if I want to add a sub in the future?

I have a kenwood kac729s amp if that helps.

Aescen

do you have front audio out jacks or is it just two rca sub outs on your radio? if that's the case you're not completely doomed, you just need a LOC to get RCA outs from the regular white-white/black and gray-gray/black front speaker wires coming from your HU.

I have a Kendwood DNX8120 head unit. There are no front audio jacks. But there is a plethora of outputs behind the unit. Are they no other alternatives other than getting a line out converter as you suggested?

Here is a stock photo of one of the preouts

When he says front, he means the set of RCAs labeled "Front" in the photo you attached. Front is not referring to their location on the head unit - the connection is going to be in the back.

I'm no expert here, but I'm not sure you can with that amp. I think you'll need an additional amp or you can upgrade the one you have.

If you are married to that amp, see if it can operate in Tri-mode. Have not seen this application in many years(all x-over's are active nowadays). If you can replace the amp, go for a 4 channel and bridge channel 3 & 4 for the sub. This is the method I used with the MTX 704x I just installed.

Edit: Looks like the KAC 729s is Tri-Way capable. Now you need a Tri-way Crossover. Might be a tough find.

RedShifter

I'm not married to it lol it's just what I've had.

Can you recommend an amp that would fit my needs so I know what options to look for so I can upgrade it?

Aescen

You'll need a solid four or 5 channel amp. I'm running an Alpine pdx-v9.

Okay so I think I will just run two amps. I will keep the Kenwood kac729s I currently have and save that for when I get the sub.

So I need to find a two channel amp that can power the component speakers.

The Alpine looks nice but that is more than I would like to spend.

RonRizz

On a side note, make sure you swap the RCA cables when the unit is turned OFF......
As 370z_roadster mentioned above, a tri-way crossover may not be easy to locate. You are better off getting a dedicated sub amp, or a 4 channel that is capable of bridging 2 channels (most are nowadays)

Its a ground issue, for sure. Your amps ground wire should be the same gauge as your power wire. It also needs to be very secure, and paint free. Sometimes its as simple as moving it an inch from where you have it to get better contact. Seatbelt anchors are typically what I shoot for. Heavy, and secure.
