Yes I tried hooking them up different ways but I couldn't get it to work right. I stopped before I fried something. I'll try again sometime. The shop couldn't understand the concept of only fronts and rms ratings so I'm on my own on this.

Ill work on the RCA wiring, but is this the correct way to wire the speaker outputs together? 

 

It appears correct, unless alpine has some weird way to wire their amps.

looks fine

Okay thanks

On that manual, i had a hard time understanding it. so both front and rear RIGHT channels on the deck are wired to both REAR channels on the amp and both front and rear LEFT channels on the deck are wired to both FRONT channels on the amplifier?

or should i split the front RCA outputs on the deck to do all four channels?

heres a link to a page to download the owners manual. http://www.alpine-usa.com/product/view/pdx-5/Specs

it seems as though your wiring to the speakers are correct though you need to use a y on the rcas for front left and right as well as rear left and right to condense the rear input to a single rca and the front signal to a single rca then connect 1 to the right channel front input on the headunit then the other to the left channel input on the head unit is how it reads
