Here's some pictures of all what I've done to my 2000 cougar v6. I'm sure it'll get mixed reviews lol.
Let's start with the wonderful wheel cover. It's almost as old as me I think and is getting a little faded but it's still awesome lol
These are my lovely seat covers.
This is the MP3 CD player I custom painted to match. Hey, it was over 5x cheaper than the absolute crappiest MP3 CD player that's actually made to go in your car. Plus they typically don't have an easily accessible aux out. Now why would I need one of those? We're getting to that lol.
Now you're probably wondering, how this all works. Well the black remote in the first pic controls half the satellite volumes and one sub. Speaking of satellites...
So basically the player goes into the rack mountable Peavy dual channel 15 band equalizer then recombines into stereo and goes into the Behringer headphone amp. That's to preserve the volume instead of using a ton of splitters and also reduces echoing interference, etc. Then that sends to the speakers. I've got a set of Logitch X-530's and Z-5300's. The 5300's have a 280 watt amp on the side of that sub and it's a dual chamber, turbo high quality sub. It produces accurate, realistic bass instead of what most car subs do but it's still capable of blasting your ears off if you want it to. The other X-530 sub is more like a mid. It has trouble going below like 50 Hz. All the satellites together can get around 120 dB and the subs are slightly louder. Plus it sounds about 100000x better than door speakers cuz they're mounted up higher, there's more of them, and they're better quality.
The red bar you see is 10 feet of EL wire. Btw that and all my neons are controlled by the switches you see up a couple pictures on the side of my center console. Here's the EL wire in context and in no light. It still needs a little tweaking so they bunch together more
On the driver's side I've got a 4" blue neon to light up that area. My camera really didn't pick it up well though but trust me, it's very bright.
the controller you see there is actually for the exterior green neons and the blue is controlled by the light up blue toggle switch on my center console. here's the outside green ones. They're waaaaaaay brighter than your standard car neons. My camera even had trouble picking it up. Btw the red light is from my LED headlamp just to show where my car is in relation to the neons so it's not all dark and confusing.
The rear has a single 4" on the same controller while the front has dual 12" but they're close to the same brightness on the ground because of how I mounted the back one.
I couldn't get a good shot of the red neon I put on top the bumper behind the grill about 2" down because I have to start my car to get it bright enough (it's getting some voltage loss down the wires so it needs the extra 2volts from having the car running to really be seen) but it looks really cool cuz there's red light streaming out the grill. The last one I installed is to replace that horrible, ugly, unbalanced, stupid looking, one side only, 10 watt trunk light. I bought terminals that fit in the sockets for the plug that powers that light cuz it's also 12 volt and replaced it with a neon inverter and a single white 4". Eventually I'll have a blue 4" on each side of the trunk instead but I didn't realize I was out of them until I started lol.
Btw extensive video instructions on how to assemble and install my exact neon kit on your car are about 75% done. I'll post it here ASAP when I'm done filming and editing it. The rear and front neon kit plus wires and supplies is around $45-55 with shipping included depending on what you have lying around as far as tape and glue and tools and stuff. All the other single kits are under $15 total for everything necessary. Oh and the sound system altogether with wiring and the inverter and speakers and all other equipment was somewhere in the neighborhood of $340. That's right I said $340. Try making your car sound that good for that price lol. Remember I even have a 15 band pro quality Peavy equalizer in there to tweak it so it sounds perfect. Door speakers + sub + amp + wiring + good player = A LOT OF MONEY!
As for future upgrades, and this sounds harder than it is, I'm going to "re-upholster" the floor thingy in the trunk so it has an enormous cougar logo on it in fabric and attach unpowered hydraulic cylinders to it so it opens and closes just like the rear door and where the spare tire used to be I'm gonna put a custom built spin up storage area for airsoft ammo and guns and equipment and of course lots of paint and neons and EL wire and all that to match lol. I'll definitely post pics of that when it's done. Here's my artist's rendition:
Now for addition Q & A because nobody's reading my replies cuz they get buried too fast (actually just A):
I covered my seats because in case you haven't noticed, the entire interior is black and the seats are tan. They stand out so much it looks like they're not even stock! Plus my couch is leather. Those seats might be leather but they're not leather. They're made out of probably the crappiest leather in the entire world. They feel like vinyl. Are you sure my care even comes with leather standard cuz I don't think they are? How could anyone NOT cover up those ugly bright tan 90's buick looking seats?
The CD player and remote don't do there, they're just there for the picture. Someone can sit in the passenger side.
I blocked up the back seat cuz nobody's short enough to ride back there comfortably without hitting their head anyway.
The entire system is secured and bolted down. It won't rip out unless I T-bone someone at 500 MPH.
NONE OF THE NEONS BARS ARE VISIBLE (except the white temporary one in the trunk) I just took it at a camera angle so you could see where it was.
The sound gear is technically home theater. Who doesn't want a home theater in their car? It sounds so good it would make you cry. It's not pretty but who cares. If I put it all in a stylish enclosure that would be a waste of money and it would sound worse and be a massive waste of time. I will however paint the wood black eventually
I do have 2 front mounted speakers more powerful than the rest (the centers off each system) up front, you just can't see them
I'm using an 800 watt inverter because unlike what everyone thinks, the amps internally almost definitely don't use 12 volt, it's probably 18 or 24 or even higher. Plus I don't have to do any wiring and can plug in any house gear whenever I want.
