Can I combine crossover frequencies?
Discussion
Hi, my old Range Rover p38 has a Harmon Kardon stereo fitted. Each door has its own amplifier with a built in crossover for low vs mid range, there's also a tweeter running off the mid driver, with a capacitor to presumably filter out the lower frequencies. I've changed the low and mid range speakers with quality replacements, but it doesn't sound right, it's too "bright" and there's not enough bass. I'm thinking of fitting a separate crossover so would like to "combine" the signals from the door amplifier. Is it simply a case of connecting the split positive and negative feeds going to the speakers, and feeding these into a crossover? I'd prefer not to blow the amp(s) up. Thanks.

That'll probably blow the amps up - don't do it!
I'd re-fit the original speakers, personally. They will have been 'tuned' to the head unit so unless you can replace that as well, you are unlikely to obtain an improvement.
As an aside, what is it you didn'tt like about the original sound? The Range Rover HK systems are very good, generally.

You would need to take the positive from 1 channel and the negative from the other.
The HPF on the mid is set at 200hz, so would explain why you don't have much bass. Also, the amp is low powered so if your new speakers are not very sensitive, the amp may struggle to drive them for sufficient bass.

The cones of the original speakers were knackered so not much choice other than look for some old ones on eBay or do as I’ve done and replace with some Focals I'd re-fit the original speakers, personally.

It’s a shame as it’s nice and clear, just lacking warmth/bass

Thanks, any other suggestions? The HPF on the mid is set at 200hz, so would explain why you don't have much bass. Also, the amp is low powered so if your new speakers are not very sensitive, the amp may struggle to drive them for sufficient bass.
