Bfii "Premium" Sound - Hi Pass Filtered

[Spoony]

I'm wondering if anyone knows if the 'premium' sound headunit feeds full range to the front (and rear I guess) speakers or is crossed over/filtered in some way?

For the time being I'm just going to swap in another sub and change out the 5x7's to something like these Ryda Car Audio - Kicker DS680.2 5x7" DS Component Speakers($145.45) up front and just coax's up the back, but it 'sounds' to me like the speakers don't get full range. It could just be the extremely crappy factory speakers though.

I know the standard headunit isn't going to be a powerhouse but I'd imagine should sound substantially better anyway.

Anyone know what sort of power output it has? I'm guessing maybe 30-40w/ch ?

Running an amp via speaker to line level converted feed is never going to achieve a real clean sound anyway.

Cheers

There is a high pass filter built into the premium sound units that filter the high frequencies to the cabin speakers.

This can be disabled when the original sub amp is unplugged. Full frequencies will then be sent to the cabin speakers.

You can pick up the low level sub frequencies being fed to the amp and do away with the need for high to low convertors as well.

Cheers, I sort of stumbled on this the other day messing about with the Aux. Aux seems to almost not use the sub at all, so I tried unplugging the amp etc and noticed changes. My guess pluggin it in 'bridges' something so the headunit activates a crossover mode/circuit.

I didn't test for line level to the amp but I assume a pair of the wires is line level I could use to an aftermarket amp, disconnecting the sub, giving better/aftermarket main speakers full range at the same time.

As long as the bass isn't cranked the headunit still seems to manage near the as with the cross over enabled
