Wow, awesome feedback guys Thanks so much. I really appreciate it. Maybe I will go with ARC Audio for my speaker amps. However, I will stay with JL from my sub amp, because I'm getting a deal on it with one of my best friends. The 900.6 sounds really nice for the SE L6's being powered by the "sub" outputs, and the tweeters and rear fill being powered by the other outputs.

I see that using the KS900.6 will lead me to use an external crossover for the tweeters. I guess that's better anyways for more control. Any suggestions on a budget-oriented external processor/crossover?

I also see that the dual KS300.4 setup won't lead me to use a external crossover/processor...

The options on the 900.6 exceed the most options on the rest of the KS line and JL audio. This amp will solve your processor issues and keep the speakers inside their recommended crossover range - and have THE ***** too.

Yes you can use an external crossover, however it's possible with the right Headunit/Amp combination. You use the Highpass filter on the Deck then Low pass the amp(s). Only issue with this route is that the L1V2 is not designed to play below 3,200 Hz at 24 dB. So be carefull with your amp choices if you are going to use the amps build in xover. Make sure its LP can high enough and to accommodate lower slopes

HAT also sell a L2X passive crossover. You could power all you speakers with a KS300.4 and bridge the amp for 350rms per side

Used processors out there will be cost effective would be an Alpine H701 with the RUX-701 controller.

Or an Eclipse 7200mkII Headunit with built in Bandpass and EQ.

The Amp is a cheap Chinese amp knock off that is laughing at what was a really GOOD amplifier-by wearing it's skin(aka.blue heat skin)

Ah, thanks for that Avidedtr. I'd prefer to stay AWAY from passive crossovers. The problem with using the in-amp crossover in the KS300.4 is that it only has a 12db slope crossover.
That processor and controller that you listed is pretty expensive... Even used. Are there any cheaper processors/crossovers that'll work?

900.6 is 12 or 24 keep that in mind same with JL

Lay

Wait.. It is? I thought it was 12db slope 50-550Hz

EDIT: I looked at the PDF, and the Sub Channel is available in 12db/24db... Not the front or rear.

you are correct - light oversight

Bare in mind too that 12db with the highpass button engaged on the 900.6 and the filter set to 550hz(10x) that puts the slope in the save zone for the L1V2. You will have a bit more overlap but that may be better depending where you put the L1v2. If they are next to each other, the 3k to 5k range may be a bit peaky. If you put the tweeter on the dash and the L6SE in the door 12db will better suit this setup over 24db. This is just my experiences with the L1v2 and L6 in a two way setup.

One of the key things in your setup if you don't plan on using a processor and plan to use basic EQ and T/A in the headunit is the independant gain controls for the amp. Arc's uses one gain pot per channel and to me this will be very beneficial to achieving good L / LC / C / RC / R. It's more manual, but the goal can be acheived with help.

Speaker placement and Crossover is everything in an SQ car IMHO - and if you want move flexibility. Try the Rockford Fosgate 3sixty.2, JBL MS8, Audison Bitone ect.

Another more costly option is to go with Arc Audio's SE line which has more power then you need or try Zapco DC reference. Whitby Hifi has stock on them and they do processing, EQ, and T/A. The DC's work for my application as did Arc's SE's. They all have their +'s and -'s

Rockford 360.2 but it's noisy

The Arc KS900.6 doesn't have a 10X option... I think the more budget oriented way would be to go with dual KS300.4 and use the built in crossovers. I probably will be putting the tweeters in the a-pillar. I think it'll cost me a bit more, but it's whatever.
