Components install on a bp5

[seith_31]

So basically while tidying up the cupboard this morning i found a pair of brand spanking new speakers 6500cx infinity. Been there sitting for ages.

The question is, i wanna install this in my bp5, do i need to use the cross over that came with the kit? Or is there some crossover happening thru the wires or my head unit? I know it already has a tweeter and a mid that functions ok. So do i just swap out the old one to the new without using the crossover that came with the kit?

Any help would be appreciated.

Current setup is

Head unit: JVC r500 wired using aftermarket wiring looms so no tapping occurred with the oem loom.

Also looking at a second hand underseat sub. Any ideas how can i wire it to the headunit? Or do i need it to run through an amp?

Thanks!

Surely you would want to amp the infinity's, not much point javing a nice set of speakers if they're going to be under powered, will sound way better with a stand alone amp..

Most of those underseat subs have amps built in so would just need rca's run from the sub out on the headunit

Factory speakers use a cheap in-line capacitor to high-pass the tweeters (which are wired parallel to the woofers). Aftermarket components definitely demand more than the 16-20W (RMS) that headunit internal amplifiers put out.

The Jaycar (Response) 50Wx4 were ideal for speakers , and fit under the seat too. They do a 100Wx4 if you're after a more powerful clean sound, good value at under $300.

Also the 6.5" speaker spacers (Ed's Auto) won't work, as the fitting screws differ between older GC8/BF5, etc.. you have to make custom spacers from 18mm MDF.
