Basic upgrade questions
Let me first start out by saying I never have been into car audio that much. Most newer vehicles have decent sound already. I know my 02 explorer sounds ok. When I got my 92 F150 last year, I guess I didn't realize how much better the new factory systems sound. Also, the truck has dual exhaust and some pretty bad wind noise, which made the factory system basically pointless. So I replaced it.
I installed a basic Kenwood deck and 4 new speakers. The sound was better, but still too weak for the truck...so I installed a Jensen 4x75 rms amp. The volume is much better now, but the 6 1/2" speakers just didn't have the lows to cut through the noise. I am a music buff. I don't listen to rap and hip-hop. I don't want to impress anyone with a hard-pounding system. I just want my music to sound good. That brings me to my next step.
I purchased another Jensen mono amp. Power output is 300x1 @ 4ohm, or 450x1 @ 2 ohm. I also got a pair of Rockford Fosgate single 8" "Punch" subs (4 ohm) 200 watt rms (400 peak). Here's my question. Am I correct in assuming I can hook these up in a series, which will create a 2 ohm load on the amp? I'm pretty sure this is correct, but wanted to make sure before installing everything.
I also got a distribution block. The currently installed amp is powered with a fused 8 gauge wire. Will I need to use a 4 gauge wire and then come out of the distribution block with 8 gauge wires, or is 8 gauge plenty for what I have?
I might also mention that I am installing the subs in a sealed box I found on eBay. Anything else I need to know before installing everything? Thanks!

Yep inside the doors, behind the carpet on the cab bulkhead, any where you can.

Advice in bold below

You would hook them up in parallel for a 2ohm load. Hooking them up in series would result in an 8ohm load
I also got a distribution block. The currently installed amp is powered with a fused 8 gauge wire. Will I need to use a 4 gauge wire and then come out of the distribution block with 8 gauge wires, or is 8 gauge plenty for what I have?
I would either run a 4 gauge wire and split it or just run a second 8 gauge wire

Ok guys. Thanks for the info. And my paint guy is dragging his feet on getting my truck done, so it will be a few more days before I get it back. Went ahead and ordered some 4 gauge wire today. Also mounted the speakers in the box.
Also, I might mention that I purchased the box on eBay months ago... before I even decided to add subs. While searching for speakers, I came across the listing. It appears to fit the standard cab well. It even has 2 gold plated connectors. However, while mounting the subs today I realized that the connection on the back of the gold connectors were just small, regular spade types. I felt this completely negates the heavy duty outside clips and heavy - gauge speaker wire. So I just drilled small holes in back at an angle to run the wires through. This eliminates the extra connection altogether.
