Aftermarket Amp wiring
I m from HongKong so my C32 is a RHS steer.
My c32 was equipped with a JVC HU from the ex-owner but the Bose Amp in the trunk was deleted. Those Bose door panel speakers were directly connect to the JVC but the Bose sub at the rear deck was disconnected.
I would like to wake up the Bose sub and I already got a 350W aftermarket Amp on my hand. So it need a direct power supply from the battery but I really have now idea how I can run through the firewall.
I have search some old threads that there are some hole for 4gauge size wire at the firewall which can be used but I cannot locate it in my C32. I would believe it is at the back side of the gloves box but no can search there.
Anyone here have more information about the holes ? Or any other alternative to solve ?
Thanks

If the rest of the system is already aftermarket, I would recommend getting an aftermarket sub instead of using the Bose sub. There are shallow mount subs that would probably fit and sound better.
for my RHS steer C32, the battery was places at LHS of the engine bay.
Yes, understand the Bose sub is not so powerful. But I would like to mod it step by step. Will replace an aftermarket sub later if the Bose is not good
I reach it finally when i remove the bottom panel cover under the glove box and see inside. But....
My power cord is too think and cannot go into those holes, it seems that those "hole plugs" can be removed but it is really hard to remove. I tried use pliers and screw drive to do but still stuck !
Any recommendation to proceed ?
Thanks

So, the plug was pushed and dropped inside the engine bay ? Can it be found ?
So, i dun mind to remove the battery to get the wire, just worry if there is any elect. failure if the battery disconnected ?
Thanks
Directly get the power from the battery is much safer
