how to get more volume out of my system?

If the customer wants louder, more power, more speakers is the way to go. All more input voltage is going to do, and a marginal amount at that, is afford him to allow the gain to go lower. If he is taking the amp to full putput, the amp is going to make the same amount of power with 2 volts as it will with 8 up until the point of clipping. So again, more power, more speakers. Louder is primarily a function of a subwoofer, look to a second sub and a second XA1000. Thanks for the correction forbidden! I was looking forward to an answer from you an haemphyst. I am already wanting a second SW7000 and XA1000, but I want my interior speakers, more specifically my front kappa perfects, to be louder. So would going with say, Boston Pro60's make a large difference in volume? Since the are 3 ohm speakers, they would draw more power from the amp and therefore play louder and clearer, correct?

From a 3 ohm speaker to a 4 ohm speaker there will not be a difference, however the boston's  may sound better.

i am fine with how the kappa's sound. I just want them to play louder! I feel like, for the set up I have, that I should be able to turn it up enough for it to be unbearable to sit in the car.

Sorry - I completely missed this thread... I will agree completely with Rob and Dan. Either more power, or more drivers. For sheer SPL, I'd go with more drivers. For SQ, either more efficient drivers, or more power. 25 watts I think is a large portion of your limitation here. For comparisons sake, to go from (1) 4 ohm driver with 25 watts, to (1) 4 ohm driver with 50 watts, you will realize a 3dB increase in output. Barely a noticeable difference. To REALLY notice, you'll want to go around 100 watts per speaker. I personally use (about) 1260 watts peak for my doors alone... (125 per tweeter and midrange, with 380 watts per mid-bass) I have never realized an audible distortion, and I have more SPL than I can EVER use on a regular basis. There is the rule... More power, or more drivers. That's all you can do. Speakermakers' suggestion of a line driver is simply ridiculous. If you are already running your amp (JUST) at clipping, that's all you will ever get out of that amplifier, (in that configuration...) with those drivers.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Thanks for the reply haemphyst! Well right now, the XA4000 that I am running the Kappa Perfect's with should be putting out about 125 watts RMS at 4 ohms, which is just as much as you run your tweeters and mids at. I can still turn the system up pretty much full volume and it is not loud enough at times. I guess I am stuck right now. I'll try throwing in a bunch more sound deadening and see how much that helps, but I doubt it will make any drastic differences. I guess what I can try next is bridge the channels of the XA4000 to the Kappa Perfects, and run the rear 6x9's off of the head unit. This will put about 350 watts RMS to each side of the front. I am just scared that this is way too much power and I will blow the speakers in a week.

As far as the more volume pitch, I could get on that boat all the way if I was to get the right answer to one question: Do you want a louder overall system or just subs? I've been watching this post with some interest because I myself want more overall output with maximum clarity. I do love me some serious kickbass (bout 60-150hz, tight and fast, ya know?), but gotta carry some serious lows. For example, Korn's Blind, that's my jam! The sub bass in that song is so low and loud, but when the rest of the music kicks in, very punchy and raw. I also want that loud. Now you fellas driving your Bugattis to the marina to get on your weekend yacht are gonna tell me go buy 4 sets of Focal Utopia 3 ways, fiberglass me a new dash and doors, power 'em up with the JBL crown amps, find myself the most obscure and ridiculously expensive subwoofers, and finally trade in my first-born for exotic materials from the four corners of the earth to effectively deaden my car. Is that about right? That is, as I already stated, ridiculous. Now, am I saying that I will achieve my goal with WalMart's best? No way. But I do believe in tuning and placement. I myself have the problem that I would like to use most of my stock locations and achieve this and I drive an 04 Stratus sedan. Yup, by-9s in all four corners with Polk db tweets in the front to just bring that stage up a bit, 1 10" CompVR in the trunk all being powered by MTXs 5-channel Blue Thunder (old school, baby) being run by a Kenwood Excelon KDC-X589. Sound great to moderate volume, but I start distorting at about 3/4 twist. Any takers?

I will take this but I am on my way out to the second job right now. From the outset, you are distorting for one of two reasons. The first reason is going to be that the headunit is well into clipping at 3/4 volume, this will vary from track to track and disc to disc as well. Secondly, regardless of the status of the amp, if it is out of gas, it is out of gas. Get a larger amp if you want it louder. Power is your friend when you want performance from any speaker, be it a sub or a component speaker. One of the guys should be able to pick up where I left off for now, time for me to go.

Top Secret, I can tell you but then my wife will kill me.

pretty much what forbidden is saying is that for high volume and good sound...you need "headroom" meaning more power than you need...why?? because music is dynamic and the amp will not "run out of gas"...it will have the power it needs whenever it needs it. like say you have a big ass diesel truck but you never haul anything...you CAN and have the ABILITY to but will use it whenever you need it...instead of pushing a lil v6 to its limits all the time it can't pull any more than its max. Well forbidden I tryed to pull what I could from your post...hope I'm right

Thanks aznboi and forbidden! So I could achieve more volume by getting speakers with a lower RMS power rating? Doesn't make much sense to me.

NONONO!!! Lower power handling DOES NOT mean higher sensitivity. For more output, you MUST either: 1: Increase sensitivity. This is achieved by changing the speakers to more efficient ones, or increasing cone area. (adding speakers) 2: Increase power availablity. This is achieved by changing the amplifier for a higher powered one, or bridging the 4 channel to 2 channels, (as you suggested) but running ONE SET of speakers on it in bridged mode. That is all you can do, man! Power or sensitivity... end of story. Lowering the power handling capability of your speakers is only going to cause you heartache, because the way you like to listen to your stuff (and don't take that the wrong way) you're gonna end up blowing your speakers in short order.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.

Thanks haemphyst! I know that lower power handling does not equal higher sensitivity, but if I am having a hard time finding speakers with equal power handling(110 WRMS) and a higher sensitivity (>90dB). Any suggestions? I don't think I want to bridge the amp to the front speakers. I would be over-powering them by a factor of more than 3 times. I do not want to blow these speakers haha. I seem to remember that I moved the jumper to the -4dB position on the x-overs. I'll try moving it back to zero or even +4dB to see how much difference that makes. I also need to get more sound deadening in there, so hopefully that will reduce the road noise a decent bit.

Unfortunately, I'm out of this now... I don't use off-the-shelf stuff, and anything I would suggest will be WAY below that efficiency rating. You'll need to check with the other guys, now.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
