Starting my audio project today.

Hey audiophiles....any words of wisdom or ideas on upgrading speakers and amp with a 1er with the Premium Hi-Fi.

You can do this with the same kit as above except with a different wiring setup.

For HiFi, you would use the 4 inputs (Front Left, Front Right, Rear Left, Rear Right) from the OEM HU to the LC6i with no summing as the signal is full range.

For Premium HiFi, you would use the 6 outputs (Front Left, Front Right, Rear Left, Rear Right, Sub Left, Sub Right) from the OEM amplifier into the LC6i with the jumpers set to sum the signals. In this case, I suspect the LC6i gains would need to be lower than the 80% I have set mine at for my HiFi system. The pre-outs from the LC6i can then be linked up direct to an amplifier or maybe an EQ before.

Have a look at page 9 of the manual to see diagrams of different summed setups.

Just a heads up, the PDX amps, while great bang for the buck, are NOT quiet amps. Every one I've ever heard had audible hiss. They're just noisy amps. I'm not saying not to use them but be aware you will never be able to get rid of all of the hiss. JL has a 5 channel HD coming that's smaller, quieter, and just as powerful as the PDX5. Unfortunately is about a grand.

I will more than likely try to see if Audison has an application I can use since their amps are ROCK solid and its what I had in my old E39
(Audison amps, Hertz components and Subs).

Audison makes some great amps but they're ENORMOUS. In the really small amp world, I like the JL HDs and the Arc Minis.

I have a JL HD600 and it also had a 'hiss' issue.

My PDX-5 is totally silent. Guess it's just hit-and-miss really. Obviously something not quite right with the quality control at Alpine. Make sure buy from a reputable seller is the advice I think.

Where is the gain set? At minimum gain, every HD I've heard is dead quiet.

It's a design flaw, not a question of who sold it. All the PDXs simply have a high noise floor. It's not a whine or anything RPM dependent, just a background hiss that's always there. It might be a quiet hiss, but it is there.

Are the SWS subs rubber surround or foam?
They look like the cheaper foam that can tear easily.
I'm looking at maybe getting a pair of these.

quality_sound · 06-18-2009, 05:16 PM

foam isn't any less reliable than rubber, especially since all foam surrounds are treated nowadays AND it will never see any sun.

I think you are asking on what possibilities are there to improve over the Premium Hi-Fi sound? I was wondering the same thing. Any suggestions anyone? Any specific components to buy & replace?

adrean8j · 06-18-2009, 06:04 PM

Yeah.....I would love for my bass to have a tiny bit more punch.

The Logic7 system in the 1 Series (as well as the 3 Series) requires keeping the OEM amp as it uses digital inputs from the OEM HU/iDrive. So to any aftermarket processor or amps to add will be after the OEM amp.

If the only thing that is needed is a little extra bass/mid bass to the OEM system then a 2-channel LOC, a 2 channel amp of 150W RMS and a pair of SWS-8 is all you need.

For example (you can find better prices in other internet retailers, this is only for item descriptions):

2-channel LOC: http://www.sonicelectronix.com/item_...Gate+LOCX.html
- the main issue here is that it accepts up to 80W max inputs and puts out a very high low level signal. The Logic7 amp puts out 70W max to the underseat OEM woofers.

This LOC connects to the underseat OEM woofer outputs of the OEM amp.

2-channel amp: http://www.sonicelectronix.com/item_...ch+P400-2.html

SWS-8 in 2 ohms version: http://www.sonicelectronix.com/item_...ms+SWS-8-.html

The remote wire is located in the back of the OEM HU/iDrive in pin 13.

^^^Sweeet Technic...that is the type of info that I needed. Thanks!

Treated? That's interesting. With what? And, are the SWS treated with that? Hard to tell from their website.

I see that they aren't very efficient either, but then being in the cabin you won't need too much power.
I am concerned about the low power handling though.
It's a cool design too.

YearONE1 · 07-24-2009, 07:24 AM

Hmm, so everythine has been sounding great. I actually need to turn my LC6I gains down for the subs, because I have way too much bass. (the highest I ever go on the head unit is 0, and am usually at -4).

I do, however, still have an issue with alterntor whine as I accelerate. Obviously, I can only hear it when the radio is quiet. But when it's off, and I stomp the gas, I can hear the high pitch whine in my speakers all the way to redline. I need to pull this apart and find the problem...

Probably need a better ground or there are some wires running to close to a positive wire somewhere...keep us posted.

Thats just it. There are NO speaker wires running next to a possitive wire, except the wires that are coming from the head unit to the trunk (IE remote turn on), but I don't think that is the problem because then everyone's would be doing this. I also moved the ground cable so it goes strait to the body from the amp.

Actually now that I think about it.....others have posted about this whine with the PDX-5's....so it could just be the AMP itself.

GtiGyver · 07-31-2009, 11:45 AM

Does the PDX-5 accept the OEM speakers even though the amp is rated for 4ohm or above on the main channels.
I thought the OEM speakers were all 2ohm.
