Navinji, B&T, When you say set HPF for front and rear separately I'm guessing it's through the 4 channel amp and not through the HU?

Many HUs can do this too.

Setting the XO at the Hu allows for flexibility and ease of setting. Setting the Xo at the amp allows that when your car comes back from servicing the Xo is still set the same.

Guess that's in the higher end HU's. I didn't find that on my pio 5750. I dont think even the pio 6850 has that.

The higher end Pioneer head units and a lot of Alpine head units allow for different front and rear crossover settings in terms of cutoff frequency, slope and output level. Even most amplifiers do not feature adjustable crossover slopes. When using a head unit as described above, bypass the crossover on the amplifier since the head unit affords you greater flexibility and is always at your fingertips.

Default Wierd HU/Speaker Problem

hey guys..
got a Pioneer 8850 (7900 USA) installed along with JBL GTO 607 comps(front) & 937 coax(rear) powered by a 75.4.
now the wierd part:
as i switch on my HU, its all fine. then as soon as i will use any functions on the HU (change track/equalizer/display settings/volume up-down from the remote) the usual Pioneer "tic" sound comes out from components, & its LOUD. TEEEEK... sigh. & the worst part, it also happens when the HU volume is 0.
This is my 4th Pioneer HU in 3 years & i have not had this issue with any before. The installer says its a common problem in the 8850 (which i wont believe) or might be a Feature in the HU (which i doubt as i searched google as well as went through the HU Manual)
If i dont find a solution quickly, i will have to get this HU changed with a Pioneer P1Y or a 6950 (which i dont want to as im in love with the 8850 apart from this issue)
Also if any other 8850 owners had this kinda problem (lbm????)

Suggestions welcome, thanks!

It can happen if your gain is very high. Please check that the gain of the 75.4 is not turned up beyong 40%-50% of it's capacity.

hey Sam
just checked it. that "tic" sound gets loud/soft with the gains. As soon as i zero'd the gains, the sound went away. but even when i increased it a little, the sound was back again (softer, but kept on going louder as i increased the gain)
so the thing is that the tic sound is actually following the Amp gain & not the HU volume. Very wierd, never experienced or heard before....

Ok Gurus a friend of mine needs help. He has M800 and an Alto. Need speakers for both of them.

Speakers will most probably go in tray. Budget for speakers 6K per car. NO components. I am suggesting him to go or 4 speakers 2 front and 2 rear.

So which ones to go for. HU is JVC in M800 and PIO in Alto. Both basic Audio / MP3 ones..
