My understanding is that the HU amp sees a 2 ohm load based on the parallel wiring configuration on the tweeters and midbass. Both stock tweeters and midbass are at 4ohm, so if the tweeter is bypassed the circuit basically becomes a single sided speaker wired in series, hence that replacement speaker has to be 2ohm to match the impedence seen by the HU amp.

another guy here installed these, and was quite happy with the sound quality

i use these, and am quite happy with them as well.

i've been meaning to try these in the car, just haven't gotten to it yet:

just note that they really need a 'bass blocker' in-line with the speaker to keep the bass away from it to play cleanly:

should try to use a bass blocker for around 200-300hz
Thanks for the recommendations - will have a look at them.

Also I have some questions regarding '2 way' and '3 way' crossover modes on the Kenwood head units if you don't mind... I recently installed a DDX918WS and it has '2 way' set by default. Speaker setups are as per stock configuration.

In '2 way' mode, the HU sees outputs as fronts and rears, hence they are lumping the door and dash speakers as single output. I was thinking if I could use the '3-way' setting to further optimize the filters? From what I see, all the speakers already have a simple filter pass installed so there's no unlikely going to be any damage.

Still a beginner at this but I'm trying to understand what I can use at my disposal to tune it to my liking. Low-end is enough for me but I would like to improve the midrange based on what I have for now... and then look at drop-in recommendations once I've gotten my best out of it.
