Default Aftermarket Amp install + Wiring

the tools you will need to accomplish this task



the amp kit i got off amazon for $30bucks and loc for $11bucks





your entry position



remove this thing (alarm horn?) unless you have girly hands



punch through here.. make sure you tape the tip of the screwdriver really well or there will be a series of f bombs throughout the night





coming out from the other side of firewall



pull power wire through without the screwdriver of course



pull up... they are held in place by clips






do the same thing and run the wire to the rear



yank up... this might take several tries unless you are muscular like me



10mm bolt... 2 on each side




lift up the head rest... theres a 10mm bolt behind the tab... you will need a deep socket for this... 3 bolts total




these two plastic little pieces are the devil but not for me since im muscular



find a hole on the deck that goes through trunk



night has fallen... getting lazy with pics... no pics of getting to the amp from trunk upholstery... if you dont know how then i dont know how you even made it this far

red arrow pointing to the middle clip... thats your subwoofer wires
yellow = right positive
black = right negative
green = left positive
blue = left negative






all 4 wires tapped using your loc



blue arrow 3rd clip is where you are going to tap for the remote wire... its the gray wire next to the pink wire




hook everything up and cross fingers



SUCCESS!!!
time it took 5hrs... didnt know what i was doing... looking for tools and info can be challenging

hope this answers all the questions about which wires to tap

Thanks for the write up! A lot of members including myself have been wondering what the best way to do this was.

I have the same amp, is that the 1200?

Honestly its good for the price I suppose but it gives off a sort of 'dirty bass' , not too clean on many songs.

You're the ***** man. Nice job. Your commentary is actually what got me through it! I plan on doing similar, but considering using an audiocontrol LOC so I can get full range signal.. w/ ppi amp. What sub you using?

cool, I thought so looks exactly like mine.

Honestly the amp is great for the price, I paid like $150 for mine brand new, best part is it comes with a bass controller.

But what I mean is 'dirty bass' is it can be sort of rough around the edges, not very clear all the time , in some songs with a lot of bass it is can be very distorted.

I want to either sell my whole set up for a single JL or at least sell my amp for a Rockford fosgate.

back a while ago i did that for fun for other people
2000 watt amps to a pair of 12" subs anther 1k for the cabin speakers.

but as cars stated to integrate the audio system more and more i got leery about tearing into stuff.
some cars have to have the stock head unit relocated to the trunk as its used by the computer to relay messages.

I have nothing but respect for you. you were willing to tear into this rolling computer and go for it.
well done.

i might add. rubber gromets are availabe at the local parts place. this allows you to pick a spot and drill a hole where its suits you. just make sure there isnt a computer on the other side.

Walmart used to have the best priced installation kits. I would save 10 or 15 bucks over my wholesalers.

Holy cow. Great job on the write up! Thanks for letting me know there's NO WAY I am going to even think about upgrading the amp! LOL.. You have much more patience than I do! Looking forward to hearing about the results. Let us know how many total hours It took!

In all fairness this look like maximum 3-4 hours work? I dont think it will take long as long as you got everything ready to work with and you have some experience with doing these things before.
