The LMS-Ultra will be better on music than the NS from numerous reviews. IMO the LMS-Ultra is in a league of it's own. Did you check out drivers from T3 and Crossfire?

Nice setup for a standard cab!

I honestly have no clue what is going on here Your diagrams and charts look nice though. Good luck with this. I wish I had as much free time to tinker as you do

Damn that cone looked like it was moving 4"!!!

The voltage from the DC alt jumped around ridiculously but voltage on average was 1v higher than my stock alt. The DC alt held voltage good at idle were as my stock alt falls on its face. Go crazy on your grounds, that really helps.

X2 I loved that "trick" face plate! Sounds great! Thanks! I will see what I can do

I took this video today. The stock alt has been back in my car now for about two weeks. At idle the stock alt runs around 14.2-13.8v with the system off. It is only a 90amp @13.8v

Thanks It gets down pretty good. It is loud but for the amount of flex I would expect it to be louder. It isnt a spl sub to begin with though. It isnt thing compared to yours I would like to get the windows tinted a little just to keep the cabin cool. With the seats up and the faceplate in it all looks stock. Thanks

I haven't had any time to work on my build. New box and trunk layout coming soon, it is going to be tits! I am dying to work on my front stage too I had to return my DC Power alt. For some reason it stopped producing any output whatsoever, completely dead Hopefully I will get it back from DC Power in good working condition Little vid of the XCON doing it's thang......... http://www.youtube.com/watch?v=SaqjvbGKRYQ

Dog food is easier to clean up then sand, good thinking.

Can you swap another amp into your setup to test? If the amp is faulty send it out for repair. You bought the amp over a year ago, I do not think the seller is responsible imo.

Glad you were able to get things worked out.

The diagram I posted is for additional wiring. Keep your stock wires in place and add additional wires. These vids may help you

If you have access to a DMM, you can get the xover set to 2500hz. Let us know and we can explain to you how to do this. Please explain how. I would imagine you just test the output of the amp until it starts to fall of but I hope there is an even better method.

They should sound better than the speaker in your avatar

thanks for looking

No chit man, good info

I like to run a ground from battery to battery, some don't. This is a very basic diagram of my current setup.

Voltage dropping to 12.5v isnt good imo. With a 225a alt and 2500wrms amp on music (doubtful you even come close to that rms rating), you shouldnt really have considerable voltage drop. You went from a RF amp to Sundown. Sundown amps are no joke. You may want to consider upgrading or reworking your electrical wiring if needed. You might even need to look into XS Power battery up front and another XS Power battery near the amp. I have a feeling you are starving your Sundown amp. Maybe your enclosure foe the sub is less than optimal. Good luck Whats wrong with voltage at 12.5? Also, why wouldn't he have a considerable voltage drop? Assume at idle the 225a only puts out 150ish, the voltage is going to drop when the alternator is reaching its output limits. I don't see how he is "starving" the amp either. With the information the op supplied he changed amplifiers and upgraded to one with 2.5 times more potential output. Therefore the electrical requirement is 2.5 times more. But.........no additional electrical upgrades were done to support all the added power. 12.5v is basically the resting voltage of his battery. This means, to me, that his amp is pulling 100% power out of the alt and them dipping into battery reserves. Dead battery anyone? 13v or higher for me or my systems is turned down. There are many unknown variables here, but my opinion stands. Op, how hot does the amp get? Pretty hot I bet. I ran my previous amp with the stock 120 amp alternator for.... 2 years I believe without incident. Voltage RARELY dropped below 13.8-14V. The time between the period where I upgraded alternators and sold my amp was maybe 2 weeks. That means that I played my "old system (old amp and sub)" for about two weeks with the upgraded alt. Voltage was fine still, obviously. The battery was replaced about 4 months ago. It's resting voltage is 12.6V. Your logic doesn't make sense. Just because I upgrade amplifiers does NOT mean I need to upgrade my electrical if it is already at or above par. I do not ride around playing tones either, so The amount of time my amplifier will draw full current is VERY short. You know about the dynamic properties of music, etc. 225*12.5 (the LOWEST voltage it will drop to) =2812.5. And this doesn't account for impedence rise. And it doesn't include the current the battery has available!!!!! I believe my electrical system is not the problem. I do not mean to be offensive, I just get the feeling that this is NOT and electrical system related problem. My friend was running a SAZ3500D to two 18" Xcons on stock electrical (150 amp alt and one battery temporarily) and he could drop to 11 V!!!!! And it was still loud as fawk. Amp stays cool as a cucumber. However, the dustcap of the sub got quite warm, which lead me to believe I was driving the amplifier into clipping, which baffles me, because it does not feel like 2500 watts of punishing power. It barely feels like 1000 watts! I mentioned one possible culprit but it sounds like you have a good understanding of the electrical aspect. Obviously I do not know that your wiring can support +2500wrms, but you do.

First of all I used the forums' search feature and I did not find any topics under "impedance rise". I currently am powering my XCON with a Crescendo 3kwp. I set the amplifier gain and ssf with my dvm. My XCON is wired for 1 ohm. With a little math my wrms output of my 3kwp should be around 1750 using -3db test tones ranging from 32-60hz. So here is my thoughts on impedence rise. I used a dvm and test tones to set my amplifier gain. This does not take into account any impedance rise between the narrow band of frequencies that my XCON plays. It also does not take into account any inconsistencies in the recording level of the music I play. Wouldn't it be beneficial for me to look at impedance rise and possibly readjust the gain setting on my 3kwp? Atleast I would be able know the average impedance of the system. I know I would need a clamp meter which would also help in fine tuning the gain setting. I have a feeling I can turn up the gain a tad more but I need more proof that I can and keep the output of the 3kwp under 2k.

Glassing...mmm...so fun. Keep it going brah! I cant wait to start my front stage!!!!!

For its age, actually for any year, your car is immaculate.
