What do you mean "minimal impedance"? What impedance is your amplifier stable at? As for wiring; JL Audio - Car Audio Systems

Word of warning; Turning your hobby into your career can make the hobby side much less fun since it becomes "work". Doesn't happen to everyone, but happens a lot. I prefer to keep my hobbies just that, a hobby, for exactly that reason. Don't expect to open a shop selling a bunch of brands that are unknown in your area and make a killing because you think those brands are great. Consumers typically buy what they know about, or don't buy what they've never heard of before. Lastly....it's a really tough field to make a living at. IMO start out small as a part time thing and see how it goes. As far as degrees; I would agree with the previous poster that it's probably a better idea to go to school in a field that is multi-purpose. Business, electrical or mechanical engineering, etc. IMO those "car audio" schools are a waste of money for what they teach and the price they charge.

Even if he doesn't have the hard copy, it's pretty trivial to look it up on Pioneer's website. Assuming it's not ancient, it should be available on their website.

In all seriousness, it would greatly help if you told us what model of CD player you have. Also, have you checked the troubleshooting section of the manual? Typically error codes or messages are all spelled out in detail including the problem and how to resolve the problem.

Sounds like you need to check the CD core.

8ohm and 4ohm in parallel is 2.67ohm, not 6ohm. If the two speakers are different impedances they will receive different amounts of power, respective to their impedance. The 8ohm speaker will receive half the power of the 4ohm speaker in either configuration (series or parallel). My initial guess with extremely limited info would be that the front speakers are 4ohm and the rear speakers are 8ohm; so when they were wired in series the overall power level was less so the speakers were both quieter and as a result the difference in respective output appeared greater than when the speakers were wired in parallel.

I'm confused......

I can't help but chuckle at the people running 4kw+ on a pair of drivers in a "daily" system. Considering the power compression occurring and the general inefficiencies involved....how little of an audible benefit they are receiving for all of that additional money spent on the amplifier and additional electrical required to support such a system.

Router with a circle jig is what you need to make a perfect circle. If you don't have those, use a Jigsaw and a steady hand. That's what I did for years...

You'll be fine. Just use common sense when setting your gain and don't use bass boost/etc.

Answer's Here

Looks good

Why are you still looking at RF speakers? As for 2 sets.....not a great idea unless you have the knowledge and experience to understand what needs to be done to set them up properly. My previous posts were filled with good advice.

thats true and i probably will end up getting something a little less than the 1000 watt.... would the difference between 500 watts and 1000 be worth double the price ($200 vs $400) The maximum difference would be 3db.....audible but not a night and day difference. Whether or not the difference is worth the price is up to you. If it were me using it on a temporary basis a 3db increase in output would not be worth double the price.

You're idea wouldn't really be the best way to go about things. If you were trying to increase output over a given bandwidth, you're best option would be to go with a properly designed (i.e. not a prefab) bandpass enclosure. But without knowing what you were trying to accomplish, it's hard to give any specific recommendations.

Because their batteries tend to explode? Powermaster 4 lyfe False. Not false. You just haven't seen the thread What causes an exploded battery? - Realm of Excursion Maybe asking where or how I got the information or where I'd seen it would have been wise before just using a blanket and blind "huurrr FALSE".

I'm not going to register on another one of Ant's monopoly of forums just to read a single thread. But "tend to" indicates that it's a problem with the majority of their batteries when the simple matter of fact is that far more of their batteries provide years of faithful service than the number that fail. Yes, if you search the forums you will find threads about Kinetik batteries that had some kind of problem. But guess what? You can find that about any battery used in this industry. You don't think Powermasters fail? But I don't go around spouting off about how all Powermasters tend to explode and fail because I read a thread on the internet. It happens, and generally when a product does fail the person using it fails to tell the full story and about how it was used and abused prior to failure. So I wouldn't exactly rely on a thread on an internet forum as indisputable proof to validate a certain viewpoint or trend for a entire brand. Lastly, without having in-depth knowledge of actual return rates and reasons for failures (etc) for both Kinetik and Powermaster you can not actually demonstrate with any validity that Kinetiks tend to fail more frequently than Powermasters. I'm not talking internet topics....actual verifiable #'s from the companies. So yes.......false, as I originally stated. Although it is fairly humorous that out of our conversation, you think I'm the one throwing around blind blanket statements when you opened with "their batteries tend to explode"...... Hmmm....that sounds like a pretty blind blanket statement to me......

Why would I ride in the back seat of my own car? I'm not wealthy enough to have a chauffeur......yet. My setups sound pretty close from both the left and right seating positions. Some differences of course as it's impossible to optimize the sound for two different seating positions given the constraints we deal with in a vehicle. So I focus on optimal sound @ the drivers side without completely neglecting the passenger side.

Out of only those two options, I would go with the Arc personally. But there are also more affordable options I would choose before either of them.

I recommended the Dayton just because it was cheap and would get you by until the sub sold. I didn't think you'd want to spend $400 on a decent high powered home amp that would power the Q to it's full potential.

Unfortunately there will not necessarily be any correlation between the parameters for the sub you "found" and your particular subwoofer considering we know at the very least the coils are different. As M5 pointed out, it was unfortunately a noobie mistake to buy a sub without knowing anything about it. I would recommend trying to getting in contact with the seller and see if he can provide accurate T/S parameters. Without them, we can't help you with enclosure selection. I'd hope the seller would be able to provide accurate T/S parameters.....but unfortunately we also have no way to verify their accuracy, which makes it sort of a crap shoot.

First I'd check to make sure you didn't accidently set the DMM to Vdc. Second I'd pull the HU out of the dash, disconnect all non-essential wiring (speaker wires, all RCA's, etc) and then check the output voltage at the pigtails themselves. If it's still low, check the HU's fusing and any fuses on the HU's power wire, and then check to make sure the HU is receiving the appropriate voltage from the electrical system.

Because their batteries tend to explode? Powermaster 4 lyfe False. And no, Kinetik is not going out of business. To my understanding they recently/are in the process of opening a third warehouse as to more quickly and easily distribute their quality product

Leave 'em disconnected also.

If your enclosure is resonant you need to use bracing rather than trying to combat it with sound deadener.
