    what hertz is best for my truck??

    Are you building this strictly for competition or is this your daily listening system? If it's your daily listening system then I'd say fuck it, as long as you are happy with how it sounds then don't worry about the meter. If this is a system for competitions, then you have a lot to learn. A 32hz tuning isn't going to have an extremely high peak SPL on the meter. In determining the best frequency to play the vehicle is part of the equation, but the combination of the vehicle plus the enclosure are going to determine what frequencies works best for your particular scenario. It's not something we can tell you over the internet, you have to do some testing to figure it out. I don't know who gave you that information about the port, but it seems extremely arbitrary. What's important for a port is having sufficient cross sectional area and low port turbulence. It doesn't have to be a slot port, round ports can work great especially with proper flare. And it doesn't have to be a certain minimum length....the length depends on your tuning.

    6.5" sub for midbass?

    You're never going to get crafty if you don't attempt these sorts of things. The only way any of us have learned what we've learned is by spending a weekend in the driveway messing things up a few times before we finally got it right. Or you could pay a shop to install them if you really don't have the tools and patience to try it yourself.

    Chrome books

    Maybe I'm old fashioned but I don't understand the point of spending ~$400 on something strictly to surf the web when I can spend on the same amount of money and get a fully featured laptop. I have an extra 20 seconds to spend to wait for my laptop to boot up. I suppose maybe in a corporate environment these might be beneficial, but for the individual consumer I fail to see the point. Ofcourse this is coming from a guy who doesn't have a smart phone & just got text messaging on his phone last year.

    6.5" sub for midbass?

    You do not want midbass under the seats. Nor in the middle of the car. In the rear can technically work but there are some conditions that would have to be met and it's not extremely easy to do right. Best place would be front doors or kickpanels. Some "subs" will work well as midbass. Others won't. So it's really just going to depend. IMO rather than try to add midbass to your current setup, you would be far better off just getting rid of the 4" front speakers and replace them with a 6.5" comp set.
  5. I think they do, but I watched that Micheal Moore doc. on them. They apparently have a high level of crime that goes on in their parking lots (theft, kidnapping, rape), they install cameras, but have no one to monitor them. It wasn't Michael Moore, it was a Richard Greenwald documentary called "The High Cost of Low Prices". Regardless, I'd call & report it to the police. From what I could find briefly via Google the value for a crime to become "grand theft" instead of just petty larceny in California is $950. If you could establish that the value they took was over that amount it would be a felony which might help your case considering it's probably on camera.

    Building an enclosure

    Hey, come up with something original next time instead of just copying everything I say.

    Building an enclosure

    Circular saw would be fine as long as you have a nice straight edge to use. A table saw and sliding miter saw will make life easier, however. Also, a plunge router and circle jig will make life easier when cutting out the speaker holes compared to a jigsaw. But a circular saw & jig saw will "work". Also, some good clamps and corner clamps will make assembly go more smoothly.

    Components Question

    Generally no, this is not a good idea. Passive crossovers are typically designed to work best with one particular speaker, or the speaker you are looking to use may need something different than that particular passive crossover offers. Generally you can expect results to be less than optimal by using a different speaker on a passive crossover that was not specifically designed for that speaker. What type of "bass" were you looking for out of these 6.5" speakers?
  9. Honestly the difference between the "real" output and "rated" output of that amp isn't going to be audible anyways unless it's horrendously overrated, which is not very likely.
  10. More than likely the outputs are internally paralleled. That means if you connected a 4ohm load to each output, the amp would "see" a 2ohm load, because internally the amp is wired in parallel. You would just want to connect the subwoofer to one pair of the outputs. You would not try to "bridge" the outputs.

    Sinfoni Premier 1 -Line driver

    "Preamplifier" is an extremely generic term that encompasses an extremely wide range of products with differing features and uses. So it would really depend on the specific needs and wants of the owner and the features of the product. Though I would not say potential benefits are limited to "SQ" systems.

    6.5 drivers/ sax 100.4d

    The passive crossovers are there to direct the proper frequencies to the proper speakers. They don't really play much of a roll in amplifier selection. You will still want to use the highpass crossover on the Sundown amp to highpass the mids.

    Sundown Skar or Incriminator?

    "Kevin"Subtillis 1800woofers Hand Built Enclosures Skar has an official forum here and a forum on another car audio forum. This can't be the same dude... "You get what you paid for" Especially enclosures. he offered cheap enclosures, you get them. You're missing the part where he posted pictures of high quality enclosures and installs that he represented as his own work (when it was not, he stole the pictures from different websites) and represented those pictures as portraying the quality of the enclosures that he was selling and that the purchasers would receive. So he flat out lied, pulled a bait-n-switch, lied some more, and then continued to pull several more antics during his internet career. He literally stole money from people by selling a product significantly different than advertised. That practice is against the law for any business in this country, fortunately for him (but unfortunately for his "customers") he was just some kid on the internet so not much could really be done. So no, it's not a simple case of "you get what you pay for". It was intentional deceit from the very beginning for the sole purpose of padding his pockets. No one said he can't seem like a nice guy in person. I'm sure he's rather pleasant. But he's still a piece of shit, no matter which way you slice it. I'm sure he was really just interested in "helping people out" by posting pictures of high quality craftsmanship, claiming it as his own when it was not, representing to the buyers that the enclosures they were receiving were going to be of similar quality, and then instead shipping shit enclosures to those individuals which IIRC were basically useless. Really sounds like he was just trying to help.
  14. Personally I would suggest a different speaker combination before you even consider active headunits. Though with a $500 budget personally I'd rather look for a used C701/H701 combo than a new all-in-one headunit.

    Sinfoni Premier 1 -Line driver

    Sinfoni is a high end manufacturer. Ideally that would mean they use higher quality parts, better build quality, better circuit design, etc. These aren't your "mass produced in China/Korea on a generic board design" line of products. While I don't know the MSRP of that particular unit their amplifiers and other products are equally expensive so that price doesn't seem entirely out of line for the brand. Value however is in the eye of the beholder. Not everyone is going to see $1050 of value in that particular product (myself included). Think of brands like Sinfoni and Brax (et al) as the Ferrari's and Lambo's of the car audio market.

    What am i doing wrong?

    Another tip: Make sure you finalize the disc after you burn the MP3's on it. In my experience a disc won't play until it's been finalized, and some programs won't automatically finalize a disc. (Atleast back in the good ole days, I haven't burned a disc in probably 5 years).

    Anyone seen or heard from Andrew?

    If you have attempted direct contact with no results, your next best course of action would probably be a Paypal dispute before the ability to do so expires. If he responds, you can correspond with him through Paypal's dispute resolution and maybe he'll be able to advise you on the status of your enclosure build or his ability/inability to fulfill your order. If he fails to respond, then hopefully Paypal would decide in your favor and refund you the money.

    Sundown Audio Phone number???

    Well, there's my problem. I've been calling 867-5309.

    Lack of midbass

    thanks man! ill look into that one! how bout this.... forget my lack of midbass topic... im looking at new midbass drivers... what amp would u guys recommend for the Selenium drivers. It's hard to ignore the fact that you are trying to improve your midbass by selecting speakers that are not going to excel at midbass performance. Seems a little like trying to use a band-aid to fix a broken leg....then asking us to forget about the broken leg, you just need recommendations on what brand of band-aid to use.

    cone area vs power

    Reminds me of one of my ex's........ Pa-zing !

    the car audio experts at best buy

    You guys laugh, but maybe they tell you that nonsense just to see if you agree with them or can intelligently argue against them. Maybe they're the ones laughing when you leave......"Did you see that guy who was just in, he really thought my system was 200db....lulz" Reverse psychology FTMFW

    cone area vs power

    Power is the least effective means of increasing output. If the options are more power with less displacement or less power with more displacement, the latter option would be the most desirable. That assumes you have sufficient room for an appropriate enclosure, etc.
  23. There are a lot of situations where you would need the ability to run different signals to each pair of channels. If you are using channels 1&2 for front speakers and channels 3&4 for rear speakers you could use the front and rear RCA outputs on your headunit ran to the corresponding inputs on the amplifier, allowing you to maintain front-to-rear fading. If you were using channels 1&2 for front speakers and the rear channels bridged to you sub, and you wanted to use the built in controls on the headunit or another preamp level device (such as subwoofer level, crossovers, etc), you would use the front RCA output on the headunit ran to the ch 1&2 inputs and the subwoofer RCA output on the headunit to the ch 3&4 inputs on the amplifiers. If you were running active you would need to be able to run one preamp channel to each individual amplifier channel (right tweeter, left tweeter, right mid, left mid). Etc etc etc. Run 1 RCA cable from the headunit to the amplifier, and use a y-splitter at the amplifier to send the signal to both sets of inputs. Some amps do have a switch that takes the signal from one input and routes it to the other input internally within the amplifier. Your amplifier apparently doesn't have this feature, however, so you'll just have to use 2 y-splitters at the amplifier.
  24. Not sure I'm understanding your question correctly. But on most 4-channel amps there are two sets of inputs; one input for channels 1&2 and one input for channels 3&4. This allows you the option to send different signals to the two pairs of channels.
  25. Why would you need to if the seleniums are capable of going up to 9kHz? Because in reality they likely can't play up that high, and even if they could it wouldn't be a good idea.
