    Need advice please.

    I Dont Know how deaf I am, but lets say pretty deaf. I have an 01 Silverado I went with #3 in my truck with some car audio/pro audio equipment and am happy with the results. I run a Pioneer 80PRS which although not as powerful as the DSP units you mentioned does everything I need it to do - Full active, Time alignment, full EQ. Now ive heard better sounding vehicles, and am hoping to make one with a build I am working on in the Family truck. But the truck is really loud and clear. Now my 01 is a beater truck so I didnt make everything pretty with the install and the there will be a huge difference in cost between #2 & #3 Labor wise, if you want to keep it looking stock-ish or in really nice condition, but the audio equipment will be cheaper so may be a wash there. I did an install on my buddies 07 silverado extra cab and was shocked at how little room there was for the equipment (Subs/amps) so def look into that as 1 of your first areas to come up with a plan. Either way can be equally good but a lot of it comes down to you having a plan of knowing what you want as the end result and then see what the budget/space ect will allow.

    Tweeter Attenuation

    You will be less likely to clip the signal with +3 on the passive and flat on the eq. I always prefer to to take peaks out with the eq rather than boost any of the frequencies, thats not always an option but its the game plan i always start with.

    I was shocked when I listened

    I know the title is kinda vague but seemed fitting. Ok to start of the main part of this post is going to be to discuss a pair of Rainbow W130 SLC component speakers I purchased recently. Ive been in this hobby for a long time now (going on 30 years, wow when I actually see that in print.......) and didn't think there were any/many things that could really make me go wow anymore. I set up a test bench a few years back and I dabble with different mids, tweets, woofers ect. I have heard a lot of great sounding cars over the years attending events or friends vehicles. I have made the natural progression from SPL to SQ but have never had a "great" sounding car. To this day one of the best sounding (Not loud enough for my liking) cars was my wifes 2010 Volvo C70 Hard top convertible with the Dynaudio premium sound. Its because of that car that I purchase Dynaudio speakers. On my test bench their Midrange speakers are the most natural ive heard and lean towards the 8" over the 6.5" in terms of uncolored and natural sounding. I found a good deal on Ebay for a 5.25" component set of Rainbow W130 SLC minus the x-overs. I am in the process of building my first "great sounding" vehicle, that, and the fact that im a sucker for a good deal purchased them. When I finally got around to throwing them on the test bench I am in the process of trying to put together a nice 3 way set up front and have decided the Dynaudio 8" and either the DLS UP1C tweeters or the Dynaudio out of the Volvo's (which I believe is a MD102 but have not been able to confirm yet) I will have to spend some time listening to both. Still haven't decided what midrange will be used, this is where the Rainbows come in. I started playing around with x-over points and a little EQing and at that point I turned them off-axis. Now over the years ive heard people talk about the imaging of this set vs that set and to be perfectly honest I thought it was 100% in the install (position, eq, delay, ect) I know speakers sound very different but I did not think imaging was a "Characteristic of a speaker" until now. Im not sure what makes these speakers so different, it cant be the size of the wave, I have tried other 5.25" in the same spot. Now these speakers sound good on-axis, very natural and uncolored, they are not the best ive heard and will say I prefer the Dyns sound over them but when I turned them off-axis its like these speakers are a ventriloquist, the image sounds like its being projected 3 feet towards the center, Ive never seen (or should I say heard lol) anything like it. Have any of you guys had similar experiences? I also realized during this just how much different speakers of the same size and "Advertised quality" can sound. I have a pair of upper end Arc audio 5.25" and I have to be honest I think they are very unnatural sounding speakers, that said I have not hooked them up to there X-overs yet but just playing them flat there is so much emphasis on the upper frequencies, its wild. Long drawn out post that I will stop babbling about now.
  4. I would say it depends on how much power you have going to it. If your going to running close to full RMS power to it youll want to keep the box on tbe smaller side 5 - 5.5 cu ft with whatever ratio you decide for the ported side. If the sub will be used gently make it a bit bigger if you have room 6 - 7.5 cu ft. Just remember that anything done on the sealed side needs to be changed accordingly on the ported side (bigger sealed means bigger ported side of you are trying to hit a specific ratio.

    Eclipse "E" series E34230

    Well it arrived, a big "E" in front of the 34230 model number 2-8ohm clear as day on the serial tag. I removed the back and found (insert drum roll here) it' exactly the same, oh and it doesn' work lol. Every piece inside is the same as all the others, I can only guess that the E's are earlier models, not necessarily that E stands for Early but it did have a lower serial number than my other 3. Only a guess but maybe when first introduced they were 2 ohm stable and they had a lot of warranties and changed them to 4 ohm? It is a true dual mono so not bridgeable, I was hoping to have found something really cool. Actually to me a functional 34230 is cool, I hooked this one to the test bench and the power light illuminated for just a second and then off, stays like that unless you discharge the caps, then the light will light for a second, if the caps are charged you get zilch when you connect power.....bummer. Just thought I'd update you on what I found

    Strapped Amps Wiring Correction?

    No, a lot of amps have multiple terminals even though they are mono. You can have multiples coming from the amp but they are all connected internally. So amp yes all together, box just depends how you wired it, sorry for the confusion.

    Eclipse "E" series E34230

    I own 3 eclipse 34230 (beastly amp ESP considering they are almost 20 years old now) 370x2 @ 4ohm only, non-bridgeable. I just bought an E34230 on eBay, same 100a fuse rating, gonna guess the same footprint but the sticker on the back shows 2-8ohm, going to guess it' bridgeable. Ive only ever seen 1 other (Kinda had to buy it, right? Lol) anyone ever seen any literature on one of these? Thanks

    Strapped Amps Wiring Correction?

    It Looks good as far as I can tell. It is normal for the positive of the slave amp to be used as the negative. If the amps are mono then it doesnt matter how many terminals are used as they will be connected internally. Check the DC resistance of your subs (They are wired in a series/parallel configuration so it should be 2 ohms, wont be exact but should be close, double check just to be sure). RB

    Strapping amp ?

    The efficincy of the amp may change a bit going from .6 to 1.3 for the better but not much. Current draw won' change much volts x amps = watts however you want to spin it so the electrical will still see the same load (give or take a little in either direction) but your amp/s will be much happier 2 amps splitting the duty will allow them to generate less heat which in the long run will make them last longer but at the expense of a second amp so you have to decide if that is worth it.
  10. To add on to one of the comments of the system sounding better with 2 ohm vs 1 ohm, damping factor comes into play. If unfamiliar, damping factor is the ability of the amplifier to start and stop I.E. change directions of the subwoofer cone, damping factor will be higher when run at 2ohm over 1ohm, that is with the same amplifier running 1 or 2 ohm. You mentioned different equipment so that may not be as much of a factor if brand X starts off with better damping than brand Y it may end up that the amp running 1 ohm still has a higher damping factor but it' something to keep in mind. Personally I like to run too large of an amp for headroom, I believe that the least amount of strain on the amp fives the best sound quality. To touch on "Crazy 8's Drum" comment about people who do SPL. It takes all kinds to make the world go round, just because you choose not to do SPL you automatically say that those people are wrong. I say you do your thing and I'll do mine and if it' left at that we can all get along, why people think that because they see things 1 way, they believe that everyone else should see it that way is beyond me, have fun doing what you do and let others have fun doing what they do.
  11. Is that to say when the cord for the bass knob is wiggled at the amp plug? Try to secure it at the amp so the plug cannot move and then wiggle the rest of the harness to see if it still makes noise, will at least narrow down where the issue is. I've had one bass knob that would make noise anytime it was adjusted, it was the potentiometer in the knob itself in my case.
  12. IMHO, more is better. If your going to push it to its max you'll most likely end up with a hotter coil by feeding it 1600-2000 watts at clipping than you would with 2500-3000 of clean power. Either way orient the subs so that it is possible to smell the coils. My .02 RB
  13. And that is why I come to you guys with my questions. As soon as I read that it was like a forehead slap moment lol. Thanks to all who replied. RB
  14. Ok, so I know this question gets asked all the time but this is a little different, not the usual "should I or shouldn't I". I've been in this game a very long time and feel that I should actually know the answer to this, but I don't so here we are. Just for sake of this post I'll use a 5k watt amp as our piece in question. If that amp is rated to do 5k at 1ohm and is only stable to 1ohm by the manufacture is it any harder on the amp to do 5k watts at 1/2ohm? Trying to get an answer that doesn't use any variables other than final impedance of the amp. My gut instinct is that there is no difference until pushing the amp to make more power. I realize that there are changes needed as far as electrical current demand goes I.E. lower A/C voltage but higher Current draw with a lower impedance and vice versa for higher impedence but just not sure if that equates to more stress on the amp. Thanks RB
