Hi,

I have a 1999 S2000 with 2-way speakers in the doors.

I have now purchased door cards with built-in tweeters.

How do I connect them up ?

Do I need a crossover ? If so, does it need to be a passive or active one ?

Any links to a suitable (cheapish) one ?

All opinions welcome.

Thanks
Bharat

I'd think about junking the OEM and replacing with a components set like the Focal 16.5cm set that comes with crossovers.

I'm not sure how the OEM wire up, I just remember being a bit confused that the tweeters had 4 Ohms written on them which suggests the only way they can be wired up would be in parallel to make the head unit see 2 Ohms - Don't the tweeters also have a built in high-pass filter (a small capacitor) or am I getting confused with the ones that came out my Golf ?

If you buy new components you will get a (passive) crossover with them, which can be mounted inside the doors.

You use the existing wiring. Plug the +/- wires into the input of the crossover, which then "splits" the signal via two outputs, one for the woofer and the other for the tweeter. You need a short length of speaker cable to do this.

That's the simplest solution.

Something like these will do very well: http://www.caraudiodirect.co.uk/alpine-spr-60c

These are a cheaper option, and you can see how the crossovers connect up quite clearly in the photo: http://www.caraudiodirect.co.uk/alpine-spg-17cs

If you go "Active", you need a 4 channel amplifier and a head unit with the correct outputs/built in in crossover and you will need to run new cable through to the doors.

(FWIW OEM on MY02+ had a crossover built into the OEM woofer).

I knew I'd seen it built in somewhere !

I have these after LG's previous advice and am very pleased with them

Apologies for thread jacking OP

Do these go straight in without spacers?

Cheers,

I dont know about those but the spr-60c I have come with a plastic spacer that make them fit perfectly.
