    Adding a DSP? Worth it? Pros/Cons?

    Your right if your happy with your sound then it's all good. Some people can't, or just don't, appreciate a good sound stage. Or they listen to recordings that don't add much to the enjoyment of the sound stage. To them a DSP is a waste. For me the sound stage and tonality is the most important factor so a dsp is critical. Speaker locations can't even get close to what like, it's just is impossible without left and right EQ and time alignment and most important the skill to tune properly.

    Mice in wifes car!!!!!!!

    Got to get those guys out of there ASAP i like the bucket. I had a rat in my lifted 4x4 suburban, almost killed my wife. We were driving down the road when my wife notice her sandwich from lunch that we had in the truck, was not the way she left it. You could see her mind working ,,, she started looking around and finally opened up the glove box, where she found the other half of her sandwich, chewed up.... At that point she looks at me with sheer terror,, and proceeds to jump out of the moving truck. It was the funnest thing ever!!! She was hanging out the truck on the door, half in half out as i was trying to stop. After about 20 minutes of coaxing, i got her back in the truck . We were speeding home as she was yelling at me to hurry up. A cop pulled us over. She told the cop that she had to get out of the truck right away because of the rat. The cop let us go without a ticket. He said it was the best excuse he ever heard for speeding.

    whats better?

    Good to know. I was trying to ask how low will they play. I was thinking they might be good at 100hz

    Where are you recomend high passing your Crescendo PWX6.5 and at what slope? I assume you run them IB in doors.

    Fried Alternator ???

    I know you're Out,,, but you misunderstood. The short in the alternator was a "complete short" it shorted the battery also. Even though the battery had power, it measured as a closed circuit until i disconnected the alternator. Just disconnecting the alternator allowed me to drive home just on battery power. like i said this was a strange happening, at least it was for me. The "birth sheet" on the Alternator showed 166 AMPs @ 6000 alt-rpm (about 2000 rpm engine IIRC) and of course they are quick blow fuses. So highly doubt anything was over stressing. I found out the alternator failure also damaged the JBL MS-2 And yeah i agree the battery was bad and did contribute to the failure. Anyway swapped it out ordered another MS-2 and its good to go.

    That van has 320 k on it it turns over fairly easily but still runs like a champ. We can disagree on the job of the Alternator. In theory i'd agree it's not for charging the battery,,, but in reality it's often called on to do just that. Anytime you have jump start a car, because someone left the lights, on or ran there stereo with the car off for to long. Or even when a car has a weak battery, the alt is required to do that extra duty. And alternators do it without issue every day. Sulfate is what accumulates on the plates of your battery, it limits the charge your plate can accept. High voltage 15.5-16 can help desulfate the plates but some chargers send too much amps and risk boil off... A low amp high voltage pulse charger can rejuvenate a weak battery be knocking the sulfate off and back into electrolyte solution... I have a roll around 250 amp charger also, but the pulse charger does a better job just take longer. The best way to use the pulse charger is to charge the battery, then discharge the battery, and repeat a couple of times if needed. I just realized iv'e had the same analog load tester for 40 years. It looks very simular to this one. https://www.walmart.com/ip/Schumacher-100-Amp-Capacity-Economy-Battery-Load-Tester/21642133?wmlspartner=wlpa&adid=22222222227016799366&wl0=&wl1=g&wl2=c&wl3=40839783632&wl4=pla-78653487152&wl5=9010806&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=online&wl12=21642133&wl13=&veh=sem

    Fried Alternator ???

    Good feedback guys, sometime it's good to think things through out loud with others folks. The battery was just enough to barely start it one time, but yeah i get now why I should have charge it up first. I just wanted to make sure the alternator could do the job, so charging it before hand seemed counter my goal. That van had the OEM alternator for at least 200K miles on there before and it took similar abuse but never failed, well,,, actually it did fail Hum. Anyway, next time, i'll charge battery first, and i think OEM or high performance may be worth the extra coin when it comes to alternators. I desulfurized the battery with a little pulse charger over night load tested it and now it's good to go

    No not really, just thinking out loud,,, and practicing my English. I never heard of the heat cycle, good to know i'm going to look into that. I never had a alternator short before I do was wonder what exactly fails to cause a alternator to short. All the alt's i've replaced just had low or no output, the short is just new to me and caught me off guard.

    Fried Alternator ???

    I murdered it alright I also been known to murder the English language! But I'm not sure why the Alt shorted. I thought as you did at first but... Here the thing. 1. It shorted 15 minutes into the drive not right away. The battery already had 10 minutes of charge on it before the stereo was cranked so at that point the battery should have been drawing much less amps as at first start up. Also the stereo was cranked for 5 minutes before failure you'd think it would have failed right away when cranked. 2. The voltage never dropped below 14.1 every time i looked (according to my 80PRS) 3. My system is every efficient, and it probably wasn't drawing any more than 40 amps (it has a 60 amp fuse in-line.) and the van shouldn't have been pulling any more than 15-20 amps.(window down no lights on) 4 . It's a 130 amp alternator cursing at 2500 RPM(which should be peak output.) 5. It has a factory a 120 amp fuse from the Alternator. So i'm assuming it was pulling 70-80 amps at the very max,,, (unless something else was shorting like a power door or... but then you'd think the voltage would be lower. Thanks on the grammar, really i can't spell chit without speel check.

    I installed a remanufactured alternator and it shorted out within 15 minutes. I've never seen a alternator internally short before and I've replaced at least 20 or 30 over the years so i'm kind of puzzled. To me it seems that the Alternator was poorly built,,, looking for opinions. Things i did wrong 1. The bigger pivot bolt was not tightened down all the way. The threads got boogered and the bolt bottomed before it made a good snug contact, so that ground point could have been better. (but the other smaller 1/4" bolt had good contact, so not sure about the ground being an issue) 2. The other thing is the battery was very week, like 9.5 volts week and i did not let it charge before test driving it. About 5 minutes into the test drive I cranked the stereo up and probably was straining the alternator a good bit. When i first started my son's 2001 honda van with the new alt the voltage was jumping 14.5-14.1 . The old one ever jumped around like that but then again the battery was week so i ignored that. I'm thinking that was kind of a red flag about the new alternator. The other thing that was strange during the test drive when alt failed, the van completely died 100% instantly due to the short. Shouldn't the main 120 amp fuse have blown first? i put a DMM on the battery and discovered the direct short. i guess the battery was too weak to blow the fuse, the wires weren't hot ether, very strange. Just thinking out loud weather this was my fault or a bad alternator.

    The future of automation is at our door. it going to look different that what we have now. Like Slo ride said robots building and servicing robots. If the minimum wages keep trending upwards will see more of it, sooner rather than later. Self driven cars, and trucks,... are close at hand. Just think the about 3.5 million truckers will be reduced to a small fraction. I agree with you that technology will make us (humans) more and more obsolete. Check this out (warning it's freaking scary, at least to me it is) Robots servicing ,,, well not robots https://www.theguardian.com/technology/video/2017/apr/27/rise-of-the-***-robots-video

    You think the solution is simply by American? Hanging on to "American" manufacturing and "buying American", is like like hanging onto the buggy whip. Times change, Manufacturing as a whole is changing whether we like it or not. In the next 10-20 years robotic automation, 3d printing, human enhancement... It's going to be a different world and there's no going back to manufacturing as it was. I hate seeing some communities hoping good paying manufacturing jobs come back to "their area", they need to get up and go where the jobs are. If we continue to think manufacturing is the answer to good jobs in America we are in for a major disappointment. If manufacturing is forced to come back to higher wage labor, it just drives companies to invest more in automation and fewer jobs are the result. Long term honestly i don't know were the good jobs are going to be, maybe service or... It kind of hurts to say it, but "Made in America" is just not that important anymore. Buy the product that gives you the value and quality you want, the free market will sort itself out, it always does. (if it's a truly free market... Non subsidized, non tariff/penalized market) Rant over

    I don't care that it's Canada's oil. As long as it flows, and keeps our prices down, and it has the smallest environmental impact than any other mode of oil transportation to date. So yeah it's a big Win Win from my perspective and it's great. No doubt some regulation have benefits but some are just ridiculous. A lot of regulation are just political games that have agendas The regulations that hold up nuclear power plants are some of the most counterproductive of all. Cleanest and safest energy available on the planet By far. Yet it's virtually impossible to build them due to red tape. Just one of many examples of counter productive regulation.

    That's funny, When i worked at Delta we'd say almost the same thing about DC-8's, except it was the wings leaking fuel. That was the worst job ever going inside the wings fixing those DC8 leaks. A freaking nightmare.
