[QUOTE="Guy, post: 1286108, member: 22717"] A little update. Everything is installed. I just finished doing my fast rings in the doors. I still have to get the amp gains dialed in. The voltage method didn’t work as well as I’d like. I have an SMD DD1 and an SMD CC1 on the way. I’m hoping the DD1 makes it easier than an oscilloscope to set my gain and then the cc1 should help me match my gains across the channels. I had trouble getting a nice level RTA until I added the fast rings and went over my sound deadening. It made a big difference in warmth and accuracy. The JL amps are nice and clean thus far and the Idatalink maestro dsr1 works FLAWLESSLY. The stock Sony amp is gone and everything works as intended, every start up without glitches. A few observations. In my opinion, the truck needs a pillar 3 inch mids next to the tweeters. Again, this is my opinion, and also partly dependent on my musical choices. Having such a distance between the doors and tweeters makes it difficult to image jazz above the dash without it sounding funny. This may be the Tonal qualities of the Hertz speakers, but the seperation makes things very bright. Bright is great for hip hop. It’s not as great for Nat King Cole. In the interim I am running a 3 inch Hertz center. Blasphemy! I know... I made this addition yesterday. Its a mono channel that’s bandpassed from 250-3500 and the gain is set just a few decibels below the other front speakers. It doesn’t affect the stereo imaging very much, but what it does do is fill in vocals in the sound stage that are significantly smoother and warmer than the pillars. This was, for me, a quick compromise until I can get some a pillars modded for mids and tweets. With the center I’m able to crossover the tweeters higher without losing the forward stage to the door speakers. Again... it’s a temporary fix. Its so I can listen to Bobby Darin without holding my ears. The stock alternator is 220amps. With big bass songs at volume I was getting some nice voltage drops. 1200 watts! Go figure. The voltage dips smoothed out quite a bit by pulling the stock battery and replacing it with a Northstar AGM group 65 battery. The factory battery is also AGM, but it’s not nearly as efficient with deep cycling. The northstar doesn’t dip below 12.9 where the stock battery was hitting 11s. The northstar is a group 65 battery but it doesn’t fit our box exactly. The terminals are reversed which means fussing with the wires a little and the battery itself just covers the mounting screw for the mounting block that secures the battery. It was a relatively easy fix. I strapped the battery down using 150lb nylon zip straps. It took drilling one hole in the battery box, but it’s not going to rattle Or bounce or go anywhere now and the straps are probably almost as strong as the mounting block. I can’t give any final impressions yet because I’m not done all the little fine tuning details. I need to dial in my gains a little better. I need to fine tune my crossovers too.
