Like the title says my alpine mrp-m450 amp and quantum audio qpp112 subwoofer and enclosure came last night. I want to put it in today but have never installed any car audio. I know all about home audio and speakers and such and I have an idea how it works and i kinda have some directions but could someone give me just a quick write on installing this and removing the HU. thanks. when ever i get it installed i will get a video. o yea i have a pioneer HU. will i have to go to walmart and get some tools to remove it.

 

The stock headunit has 4 holes, 2 on each side. They're literally round holes in the front that you need to find. Go to your kitchen and steal 4 of your moms shishkabob skewers. Then you stick them in the holes and bend them (either in or out, just dont snap them) and use the bending motion as a pulling out motion. I think you bend them out to remove the headunit. Then once you have it out, you hold it in your hands and unplug the connections behind it. They're those annoying lil clicky latches you have to use a screwdriver or something to pry up.

Bad explanation, just attackit he front with 4 skewers. They also sell a tool

to remove the H/U, if its like mine, i found it easier to just take the whole radio bezel off, two screws at bottom then it popped off, radio will come out with it, push in the clicky things on each side, and bingo, radio should come right out-the tool idea didnt work for me so i just pulled the whole thing out

 

i have a pioneer HU already installed but i will try the radio bezel idea. what about installing the amp and sub.

 

You gotta run a + battery cable from the battery to the amp. Run a ground cable to a good grounding point (I used the rear jump seat bolts). Then run a remote wire from the headunit to the remote port on the amp (blue wire or blue with white stripe.. cant remember haha). You also have to run RCA's from back of the headunit on the subwoofer out to the inputs of the amp.

 

anything else importang i should know about?? i have some serious wire online car stereo sent me wrong wire and just let me keep it. i have 0 ga. instead of 8 ga

 

To hook up your amp you want a lower guage wire-8 guage is sufficient, but if you have 0 guage wire, and you have enough, hook it up,
bigger wire means less risistance means more power output
remember to put an inline fuse on your power wire to your amp-should be less than 18" from your battery and no baby fuse either, you need like a 60amp fuse for it
Go to best buy-or similar store and you can buy an amp kit that has everything you need including-not limited to-depending on what you buy
power wire with fuse
remote wire
ground wire
speaker wire
rca cables
and closely follow the directions with the amp to correctly install it
and make sure you hide the wires and dont half way it, make sure you make it look good
its simple to do, and the directions with the amp should be able to give you a good idea how to do it

 

well guys i have it all hooked up and i have power and all but no sound out of the woofer....i have it turned on in the back of the head unit but its like i am not getting a signal....what could be wrong.

 

more then likely got ur remote wire hooked up to the wrong wire...what one do u have it hooked up to?

 

check the following
-turned on at H/U
-check remote wire is correct
-check rca wires are right
-check make sure speaker wires are right

 

i had bad RCA wires...i replaced them and now it works great. Finally 1000 dollars later i have a perfect sound system. i will get a video for you guys. Thanks for all who replyed back.
