questions:
1. below is right out of the owners manual for the amp and it states 15 amp fuse needed and im pretty sure my jeeps radio fuse is 15 amp so im good there right? this means i dont have to run a cable through the firewall to the battery correct? it will get its power from connecting to the alpine deck wire harness.

6 Battery Lead (Yellow)
There are two options:
a. Connect battery lead to OEM radio fused circuit
The OEM radio circuit has a fuse to protect your
vehicle’s electrical system in case of a short circuit. Do
not connect the battery lead to the OEM radio circuit if
the fuse rating is less than 15A.
b. Connect battery lead directly to BATT +
Be sure to add a 15A fuse (sold separately) as close as
possible to the battery’s (+) terminal

2. Will this amp power all of this properly?
how do i connect these products to the amp?
do i have to bridge? how do i do it.

little bit of novice at this, but i learn fast and cant afford to
pay for an install right now. thanks for the help.

 

If you haven't bought that "amplifier" yet, don't. You will want more power almost immediately.

Look for a real 4channel amp or use the deck for the speakers for now and get a small ClassD like the Alpine M500 for the sub.

To actually answer your question, yeah Alpine figures it's ok to run that thing off the yellow lead for your radio. IMO that is your first clue it doesn't have a lot of power..

 

I recently bought the Kenwood 8105D Mono amplifier.

This unit will do 300W into 4ohm, or 500W into 2ohm.
It's powering a 250WRMS 8" Cadence S1W8-D4 (Link)
I built a small 10"x10"x9" sealed enclosure for the sub, which may be a little on the small side, but I haven't heard (or seen) any adverse affects yet.
The dual 2ohm coils are wired in parallel to raise the load to 4ohm, so the sub is getting 300W, 50W over RMS.
Quite frankly I'm LOVING this setup. Together, this pieces cost me $260 CDN, after shipping, duty, and taxes - both pieces were shipped from the U.S.
The links I put up are where I ordered each piece.

Here's the thread about my build...

What is the pricing for the items you have listed? JL Audio is expensive, in my experience.

What is your head unit's make and model?

 

 

Thanks Dukk. Not sure what I was thinking this morning...
