Re: Need set up advise

Hmm that's an interesting idea. What would I gain from that? The ZPAs are capable as each Channel has its own gain control. You eliminate channel "cross talk" during amplification. In theory your channel separation is infinite at the amplifiers' inputs because even if there is cross talk ...

Nice work. Planning my E90 sedan install now, I'm loving how much of the work BMW has done for me already in this car!

Re: Need set up advise

I don't think you can go wrong either way. My only concern would be how you would be mounting option two without imaging losing focus from up high enough and in front unless those 3's play pretty low, not a huge deal to overcome though. Have you considered going dual mono with either option? ie one ...

Re: Almost ready

Your best bet is to have the roof skin removed, reinforce it, then re-skin it.

Go down to Mike/gastroker. See how he had a sunroof, then he didn't? Re-skinned, it wasn't that bad either from what he told me.

Re: best android dock for car?

I was frustrated by this situation with my car. The problem with headphone jacks is that they are optimized to drive the lower impedance presented by headphones vs. the 5k-10k input impedance of a true line level input. I was using an ipod and an iphone, so at first I bought a fiio L11 Line Out Dock...

Re: Tuning Coax Mounted Components

So time alignment can only do so much, especially working with such a wide high pass band, as you found, then it will just wreak havoc and cause terrible combing. If I were you, I would probably spend minimal time on this right now if you can get it to sound acceptable knowing its temporary. Once yo...

Re: Tuning Coax Mounted Components

I thought we were talking about just swapping the tweeters polarity but it sounds like you swapped the whole component? That I would not recommend, putting one side completely out of phase will just add to canceling and make bad sound. me too, I just use "driver" generically. Probably wan...

Re: Tuning Coax Mounted Components

Yeah the attenuators in the both xovers set the same. I was in there a while ago to change the crossovers. Would it ever help to change the phase of the tweet only in a coax mounted component set? Then the mid and tweet would be out of phase. If it's coax, that's not likely going to change anything...

Re: TBA1 questions

I would also keep investigating this before you throw a new alternator at it, but a couple things to consider. Assuming you read 14.3 with the car idling and little to no load on the charging system, its still possible the alternator, or part of it, is faulty. Since you're chasing a noise issue, you...

Re: whats up everyone, back from the dead, need bmw install

Because the Logic 7 transmits audio from the head unit to the OEM amp via the MOST ring, you need a processor capable of decoding the L7 signal which is a proprietary digital signal specific to the HK systems. BUT FEAR NOT...any BMW Professional head or iDrive unit can be coded/programmed to functio...

Re: Think I have a phase issue...

Crossover summing is a huge pain sometimes. Without looking up specifics on all your gear, the first thing I would try is using one device to handle crossover duties for both high and low pass. Using 2 different crossover alignments will cause numerous response issues in your stop bands and will be ...

Re: Line driver help

I lowered the line driver gains for my front speakers to zero and the distortion dropped significantly and I no longer hear idle noise. My amp gains are still at zero, I just increased my ms8 volume a little. So my question, is the Line driver supposed to give a voltage boost even with zero gain? I...

Re: Line driver help

The first thing that jumps out at me is the MS8's SNR listed at 90(db I assume, it just says "90") for the line level stage. I think the least expensive amp I have specs at >100db. The SLD44 specs at >110db for line level for comparison. That really shouldn't be causing distorted transient...

Just drove home at like 8am from the club trying to implode my eardrums with Songs In the Key Of Life so I'd say bridged @ 8 sounds just fine. Clearly not stressing the electrical like before either. Thanks dudes.

you dont need to change anything in your signal path. just wire the sub's coils in series inside the box and you will be set Your sub will sound much better too, if you run it at 8ohm bridged. Especially if its ported. No need to touch the signal cables, just put the subs coils in series and that w...
