Hi All,

I have a few question which I need to put into perspective before I can go looking for gear.
I have a 2003 TL Magna and I would like some better quality than the stock audio. To start with this I already have an Alpine 9852 Head-Unit.

I will just put my story here and please correct me if I am saying nonsense, I spent some time reading on stuff in the audio section and got some idea's but it is missing some pieces here and there. I'm also a bit new to the English car audio acronyms as I am not English.

Now, I would like to get a Sub, door speakers and an Amp. I want to run the Door speaker (Kickpanel?) and the Sub from the Amp. For this, I read, I need a 4 channel amp. Connecting the door speakers to 2 channels and the sub bridged to the remaining ones. Is this a correct set-up? Are the door speakers called splits?

I also want to put tweeters into the pre-prepared holes in the dash. And run the tweeters and the boot speakers from the Head-Unit. I have read that the tweeters come with filters to filter out the correct tones/frequencies, is this correct? Do these filter need their own power source, or do they feed from the speaker power?

Now, Is this overall a decent set-up, or should I do it different?
I want to go for quality and not for SPL (?). I think I need to upgrade the door speakers as well as they probably cannot handle the power of the amp?

Please let me know if my idea's are plausible.

If you made it this far, thanks for your time. :)

OK after reading all that i'll throw these at you:
- Door speakers can be splits OR coaxils, splits is when you have more than the 1 speaker detached from the woofer, coaxils are when you have 2 or more speakers attached to the woofer. What you are saying is you want splits (woofer in door, tweeter in dash).

- The tweeters run on the same power source as the woofers, well you'd want this to occur otherwise your tweeters will be VERY quiet compared to your woofers and you will barely be able to hear them.

- The "filter" you're talking about is what connects your woofer and tweeter to the power source. So if you wanted to run the tweeters off your headunit, you'd need 2 filters per set of speakers (which you don't want to do).

- The "filter" doesn't need any power sources, it just runs off your amps output and divides the signal to the woofer and tweeter.

Other than that, :thumbsup:.

as for the basic setup which you are after
i also have a TL and got a decent setup in my car
as for the splits go and buy some 61/2" splits they should sway over with the current speakers in the doors, might have to redrill the holes, as for the tweeters you should have tweeter pods on each door and the tweeters that come with the splits should just sway with the current ones
as you said that you are buying a sub then you wont need 6x9's in the rear, should be able to pick up some nice 61/2" coaxils with some spacers
if your looking at only getting one amp then yes all you will need is a 4ch amp to run the splits and sub, the coaxils can be run off the deck

Yeah a 4ch amp will run you set up.

Just to note, I would run the tweeters off the amp with the woofers if you get splits. If the xover is combined or separate it will not matter and it will sound better with your set up. I have a dockable filter system with mine meaning that I can run 2 power sources into 1 set of splits but you don't need to get that hardcore.

Just make sure you buy a sub that can deliver a 4ohm load ( i.e. SVC 4ohm / DVC 2/8ohm ).

Big thumbs up for looking around before posting! Just make sure you don't get talked into buying crap.
