Definitely a improvement in the low end. My stock woofers were Harmon kardon ones and they noticeably feel bassier.

If you have base or hifi, then you'll notice it even more .

I actually have harmon kardon set up but I have an aftermarket amp powering underseat hk woofers and 10inch jl sub in boot. Using the technic harness.

Hmm this could be interesting uograde..

Why did you go for these vs the other UK ones like audison etc

Also stock hk woofers are 7/8ohm., are these definitinely 4ohm.

Are these definitely 4 ohm woofers as the stock HK amp is 7 ohm to underseat.

This is important as my aftermarket amp is 2 to 4 ohm to get most of out it. If its 8ohm, I will lose half the power

Do you still have these mate? If they're 7Ohm I'd definitely be interested. Cheers
