Installing An Amp In a Toyota Celica Gen 7

Tools

Phillips Screwdriver

A socket set, (all you will need is the 10mm socket and the long bar to fit in a small gap)

Somewhere to store your screws

Patience and hard graft.

Lets crack on!

Step one, remove the 3 dials and the front of the slider. These simply slide off.

Remove these 2 screws

Now move lower down to where the gear stick is and pull out the gear gaiter (leather around the gear stick)

Now being firm but careful, the trim around the gear stick will pull up leaving:

Those are the cables I have put in before creating this guide ignore them for now, this then leaves the trim surrounding the dials exposed:

Now remove these 2 screws, It may not look like it but these 2 screws as well as the 2 taken out of the dials earlier are the only things actually holding the trim. Carefully pull the trim towards you and you should notice the whole trim comes loose and you can slide the whole trim off:

Disconnect this plug, there is a small clip on top of it, push the clip in and slide the plug out and you can disconnect the whole trim. This exsposes 4 screws:

Unscrew these using your socket set.

Now the whole head unit will come loose, remove the old unit by unclipping and pulling out all the cables connected. At this point your best off connecting the phonos, the aerial adapter and the new stereo wiring adapter. This is also the prime time to connect you remote lead. The ‘Remote Out’ on the head unit is the ‘BLUE’ / ‘Blue and White’ cable leaving the connection to the head unit. Connect the ‘Remote Out’ lead to your remote lead however is best for you, I soldered mine and then taped it with electricians tape

Now thread the other end of the phonos and remote cable down through the back of the back of the trim ready to go back. Now screw on your fascia adapters and if your using a single din head unit the bottom din blocker aswell:

Now its all connected get your socket set out and screw your head unit back into place making sure you have fed the remote lead and phono cables down to a place where you can get hold of them. Now, you don’t have to do it this way but I think it’s the best way, you may disagree.

Feed the remote cable down the back under all the trim and down alongside the gear stick and handbrake (as shown in the previous picture with the power lead I’ll talk you through the power lead fitting later) and run the phono cables right towards the drivers footwell.

Now run the phono cables across the lip of the drivers footwell. These can then be cable tied up to the gap left for the bonnet pull:

Now, unscrew the footwell trim away from floor carpet and feed the phonos down into the trim. Now the trim is loose pull the cable through. For the next part you are going to need strong fingers and not worry about doing any damage.

You will need to remove the whole side trim at once, you need to get your finger under either the very left where you just unscrewed the footwell trim or the very right where it meets the trim for the back of the car. Pull the trim up little by little moving down the trim. It seems to come up easier if you pull under where the ‘Celica’ strip is. You will hear the trim popping up and you’ll eventually get the whole of the trim off:

On here I have pointed out where a clip was left clipped into the body of the car rather than coming off like the rest of the clips. This can easily be removed using pliers and easily slotted back into the trim for re-fitting. Now run the cable down the side of the car with the other cables that are already there, the white slots simply slide out to allow you to lay the cable and then slide back in.

Now run the cable into the back and feed up through rear trim this is just simply pushing/tucking it under the trim and running it up to the rear seats. You can then feed it down the side of the seats, hiding the cable with the side of the seat. Feed the cable into boot underneath the rear collapsing seats.

Now in the boot you may have a shelf at the back this simply removes with a sharp tug at the right and left hand sides:

The little clip circled above may pop out and there is one on both sides, hold on to these. You should now be able to see the phone cables.

Success we have the phonos installed

Remember to hide the cables using the base of the seats, clip the side trim back in place and re-attach the footwell trim to footwell carpet.

Now for the power cable,

Get yourself in a good position do you can see above the pedals and so you can see looms of wiring running left to right. Now you will need to look above the accelerater and alittle to the right and you should see a bunch of cables running into the engine bay:

Push your power cable through the hole next to the bunch of cables you can see. You will need to push through a good couple of feet of cable until you can open the bonnet and grab the cable. Now open your bonnet and pull the cable all the way to the battery so you know exactly how much cable you need in the engine bay and how much u can use to get the other end to the amp.

When you have the cable through attach your fuse and to make sure you don’t accidently pull the wire back through into the car you can tape it down.

Now back in the car make sure you feed the power cable up and out of the way of the pedals, we don’t want any accidents people.

Now feed the cable down the back of stereo trim where the remote cable is also running as shown:

Now actually getting the 2 cables to run through as above you will need to get your screwdriver out again. Firstly unscrew the window controls:

This then slides out towards the front of the car then lifts up (no need to disconnect the cable to this):

Now unscrew the centre console where it meets floor:

There are 4 screws two on the drivers side by the side of the seat and 2 on the passengers in the same place. Remove these and don’t go loosing your screws.

You now need to open the compartment at the back of the centre console:

And remove the small square of carpet at the base of it, this reveals 2 more screws which you will need to unscrew using your socket set.

Now, the whole centre console should be pretty loose and easy to manoeuvre. At the base of the centre console near the screws you just removed on the drivers side there is a small bridge. Push the power and remote cables down through this gap this then allows you to pull the cables through to the back of the car:

This doesn’t look good at the minute because the cables are running loose down the side of the drivers side but bare with me. Lift the rear of the centre console up and tuck the cables up and under the loose trim.

Now the only cable you should be able to see is sticking out of the back of the centre console towards the rear seats. Now run the cables round the rear seats to the opposite side you ran the phono cables, again hiding the cable and threading it through into the boot. All the cables you need are now in the boot The only cable you should now be able to see is about an inch or so of the power and remote cable where it leaves the rear of the centre console trim and disappears under the rear seats. Unfortunately this is unavoidable but the cables are not noticeable.

Well, all that’s left to do is wire up your amp and sub. Re-fit all the trim and screw everything back in, slide your dials back on and connect your power lead.

Start the engine, put on a good track an sit back and enjoy the bass! ;)
