22kohm is for the signals impedance or for the VC impedance? sounds odd that way...

use a multimeter will do...

Need to find out the power rating for this sub oso

shouldnt it be 4 or 8ohms usually?

Mind sharing your current setup?.

hmm.. ok. Whatever your ride is, I truly respect it. I'm not gonna comment so much as you have already spent money on the HU so no point going back on that unless you tell me that you can sell it to a friend for the same price you bought it for.

When you want to do it all again, feel free to msg me and I could share with you on the things I would have get from the start.

But.. bro, as a tip, no matter how bad or how good your ICE setup is, try filling your door panels with Dynamat or something equivalent of a sound dampening material and making sure your cables are tightly and neatly in place (cable ties are good to anchor them to something solid and non-moving, try using insulating sponges for air cond gas pipes too) and anchoring them making a solid and non-movable/rattling environment in your door panels.

Try to cover as much surface with sound dampening materials as you can (inner and outer walls of the panel) even though it would mean that you cover up the entire holes in your door panels (You hardly open your door panels anyway unless there's something wrong with your lock or power window so no harm covering/wrapping the entire thing). Unlike European makes, I know kelisa have generous size of openings to reach to your power window motor.

However sadly the mentality in building cars in this country only have maximum profit in mind sacrificing material and labour quality, they tend to have many rattling noise especially when they age a little. Main culprits are usually found in the car trunk panel.

If you can and are really serious about SQ, rip your car apart and establish a good and solid sound dampening where ever you can (as mentioned before, all doors including the trunk panels would be a great start then working your way towards the roof, floor firewall etc - optional thou).

With this in place, I can assure you that your beginner setup will sound like a pro.

You will even find that the low frequencies from your mid woofers suddenly come to live, bass feels solid, just right with it being precisely short and tight as oppose to those long annoying bass extensions echos due to your empty door panels and you may consider that you might not even need a box subwoofer after all haha.

Hell, even shutting the door for your girlfriend getting in the car will suddenly feel so good and you will fall in love with your kelisa all all over again

Good luck bro.

p.s sorry for my really long sentences.

My pleasure... Just helping out a fellow enthusiast. I left all these few years back.. looking at you makes me wanna start it all over again but no money la..lol

Btw, Whats your budget in mind? Maybe go step by step?
