I'm almost done with my system - finally. So far here's what I have:

Car is 2000 Gs4 w/ nav
Factory Head unit - LOCs connected to all 5 Channels
Alpine V12 65W X 4 - powering Dyn Audio 240 GT in front and (blah) stock in rear doors
IDQ12 deck / Free air mounted sub powered by JL Audio 500/1


Considering the crossover points built into the factory amp...
What shall I use in the rear doors?

Overall the systems does sound good ... but i do lack some lower bass frequencys in my door speakers. I was thinking of adding the Dyn MW160 GTs in the rear doors. Opinions?

Does anyone know how much space (width & Depth) is available in the rear doors for mounting?
If enough I can go bigger than the MW160s?

I'm still trying to find out what P1 P2 and L are in the audio diagnostic mode. I asked a mechanic at lexus - I'll post if I hear anything. I know a several club people are waiting - If anyone knows DO TELL!!!

 

I'm running MW170's in my rear doors. Mounted on 3/4" MDF with plenty of room to spare !! I have them crossed over @ 63hz - 12db slope. I have 1 JL 300/4 running a System 240 in the front and the 170's.

Are you using the stock headunit/amp????


How does it sound w/ no tweeter in back?

 

No the stock stuff is gone. I'm running a Pioneer DEX-P9 HU and the DEQ-P9 processor. Using time alignment, it's as if all the speakers are right up front ! You are correct, I have no tweeters in the rear, but then again I rarely have rear seat passengers. I set this system up for me, and not for anyone sitting in the rear seats
