Crossover Wiring Question

[Mr Morse]

When wiring up a crossover in the front door panels, what do I use as the feed +ve and -ve into the crossover? Does this need to come directly from the head unit?

If it's a passive crossover (that works at speaker level) I'd say from the speaker output on the head unit.

If it's an active crossover (RCA in/out, works at line level, feeds amps) I'd ground it to the chassis and take +ve from a relay that's operated by the remote switching wire from the head unit.

Yep it's a passive crossover (Infinity Kappa component system).....I'll give it a try from the HU

Upgrading the sound system too Mike ?

[Mr Morse]

On the MR2......

Alpine CDE-9850Ri headunit (iPOD compatible)

Alpine SWD-1600 amplified SW

Infinity Kappa P6.1 fronts

Infinity Reference rears

just a bit of a PITA having to have to run cable from the HU to the crossover in the door panels

[MrADeveci]

Nice ..... :D

[derekyau]

I thought he was gonna ask about network cables at first! lol

[Mr Morse]

All sorted

Rather than running new cables through the door grommets (PITA job) I just used the existing feeds. Got it all wired up and the new system sounds awesome.....at Volume level 12 I can't actually hear the NUR-Spec
