Please Help! Aftermarket HU and Speakers

First off I want to point out that im not an expert with audio. Never really got into it so I dont know much when it comes to wiring or audio systems. I worked on trying to install my system for 2 days but I cant figure it out I also tried searching but no one seems to have the same set up I do.

I originally had the HK system in my car. The HK amp in the trunk was removed and all thats left is the speaker wire harness and dangled freyed wires (there used to be an aftermarket system installed but was removed). I found a chart that outlined which speaker wire goes to which speaker to sort out the wires and labeled them.

First Attempt:

1.) I installed headunit harness to harness that connects to stock harness as follows:
Red-->Red
Yellow--> Yellow
Black-->Ground
Blue/white-->Blue

2.) I then ran RCA output from HU to the trunk into an aftermarket 400w 4ch amp. I also have converters connected to RCA cables.

3.) Based on the speaker wire chart, I connected each set of speaker wires from the wire harness in trunk into crossovers.

Crossover 1 - Right Front Tweet, Mid, Sub
Crossover 2 - Left Front Tweet, Mid, Sub
Crossover 3 - Right Rear Tweet, Sub on rear deck?
Crossover 4 - Left Rear Tweet, Sub on rear deck?

For the front speakers since there are 6wires total and only 4 slots on the crossover I overlapped the mid and sub wires together in one slot.

4.) I connected the crossovers to the 4 channel amp. Each crossover connected to one slot for each corner of the car.

The sound was muffled and was not clear. I had to turn the volume on the deck all the way up to hear little muffled sound. This was for Radio and aparently no sound in Aux mode. didnt try any cds though.

Second Attempt:

I tried to go a different route and just put 6.5 speakers in front door panels and forget the whole high,mids,low set up.

I hooked up the speaker wire from the stock wire harness in trunk used for the front door panel speakers and connected it directly to the amp.

The sound of the speakers were still muffled and low and had to turn it all the way up just to get little sound out of it playing Radio.

What is going on here!!! What am I doing wrong!?

Im thinking of doing this now:
I want to hook up the pioneer deck and put 6.5 speakers in front and rear in each corner. Can I run the speaker wire from the headunit harness to the trunk and wire it direct to the speaker wire harness? Will that work so I can just avoid using the amp and crossovers?

Whats the best way to wire everything for good sound?

Is the RCA out on your head unit a subwoofer output? That would ecplain the muffled sound. Post a link to your exact model head unit and amp, that will help a lot.
