Too Much money to get it to my taste. Went with a 2012 Infiniti G25x (AWD) instead. A great car for all year Canadian driving

Sold it, yep.

Thanks a lot, it's been a while I've wanted a set of those on my car. Really happy of the result. Handles great too !

So, I did a thing, love them !

Yeah forgot about Rivet nuts, you could use those, You need to crimp them with a special tool but you would have a strong mount with this.

It is hold in place by 6 metal screws, I don't exactly know the weight, main like 15-20 pounds. Having inserts would be hard to put since there are not really any acces between the metal backing and the seat itself. I do no recommend milling the rack in aluminium, it's gonna be heavy and really expensive. If you want to save weight, you should go with sheet metal aluminum, with some bends are the right place you'll have a clean and solid rack, that dissipates heat too.

Yeah sure don't mind if you do! The back of the seat has a metal backing similar to metal sidings, like a waved shape, it's pretty solid, well enough to hold a amp rack.

It actually is in two parts, the top layer and sides are fixed together then fixed to the base. The base itself is fixed to the back of the seat, with metal screws. What you may see is there are holes on the plate where the amps are mounted that makes possible to screw the bottom layer. Here is the 3D cad of it.

Previous setup didn't last long, ditched the old crappy amplifier and bought myself a MRP-F300. Built a new rack to hold both amps and the lc6i. Also decided to keep the 12 inch subwoofer.
Pretty happy of the sound and the look too. Looks clean (still need to zip tie few wires) and still can drop down the seat, if i need to put something long in the car.
Would be happy to hear your thoughts !

Show the rear, it looks even better

if your car is a 2003-2005, you need a 2005 accord ECU, if the car is a 2006-2007 , the stock ecu can be used.

So, went ahead and bought a used alpine 8 inch type R subwoofer with a ported box. Then searched for a matching amplifier and found a cheap sub and amplifier combo, a alpine MRP M500 amp and a 12 inch alpine type R sub in a sealed box. Intalled the amp and tried both subs (one at a time). The 8 inch is pumping quite a lot of bass for the size of it, but the 12 is definitively more powerful (might be too much actually) , and takes more place. Hard to decide. Anyways, here are pics of them.

I've finished the install, The sound is really decent. Clear and no buzz like i used to get. I know carpet would make it look better but since the amp might not stay there long, I don't feel like doing it. I use Solidworks for my 3D CAD drawings.

Now i feel like i need a subwoofer, The sound i get is clear and loud, but no bass presence, and if i try to cheat and turn up the bass on the headunit, it sounds like crap. I might be interested in a powered sub box since they are quite compact easy to plug ans unplug a quick plug for power would be nice too, don't want to use too much cargo space. Don't know what size power i need tho, too much choices to look at.

So, finally went ahead and bought myself a LC6i to hook up my amp with the RCA inputs.




I absolutely wanted to be able to put stuff throught the opening of the back seat, so it needed to be mounted to the back seat. the thing is the space is too little to fit both amp and loc back there because of the "ski trap" (that what we call the opening in the middle anyways).




So what i've done is measure the space available and 3D cad the back seat and the audio components. Then I designed a simple mount for them to be on.




It fits pretty well, I now only need to connect everything up and tune it. Quite excited to test it out.

uh, yeah it can, when it still is on fast idle. it can go pretty fast on its own, it will even shift into 2nd
