number3 Posted January 17, 2010 Report Share Posted January 17, 2010 Hey all, this will be my first post to this forum, don't know why I didn't join sooner but here's my questions: I recently added a small system to my Mazda Protege (2 12's, 600w, blah). I'm on a budget so I'm upgrading as I can. I want to get the most out of my crappy amp that I can and am looking into upgrading the "Big 3". Every other resource I have looked at as to how to do this properly has given me different instructions so I wanted to take my questions to the hundreds of bass geniuses that frequent this site. My alternator is hidden under my intake manifold and, though I have not looked too closely, I cannot find the +/- wires that come out of it. Basically, I just need the basic instructions on how to get it done. My other question is how can I tune my amp/subs to hit the lower notes? I do fine on high notes but when it comes to low notes, I can hear them and everything but they sure as hell do not sound as evident as they should. Any suggestions? Thanks for all the help guys.

enemyofsilence Posted January 17, 2010 Report Share Posted January 17, 2010 if you want to hit lower nots, you have to build a box according to your wants. you can't just "tune" the sub or amp for lower notes. you need the box required to do so.

crazyfrazz09 Posted January 17, 2010 Report Share Posted January 17, 2010 we need to know a little more about your system to be able to tell you what you might do to help it. what kind of amp and subs? is the box sealed or ported?

I've got a 600 watt amp w/ 2 12's that came as a group that a friend of mine gave me. Here's the link with specs. http://www.sonicelectronix.com/item_3522_V...ed+System.html# This is definitely not even mediocre but it still hits. I've replaced the box with a cheap prefab ported enclosure that seems to do a better job. My HU is a Kenwood KDC-MP242. Running 4awg power and grnd wire in preparation for a larger amp. Those should be the only important things at the moment. Hope it helps! Quote Link to comment Share on other sites More sharing options...
kl0wn Posted January 18, 2010 Report Share Posted January 18, 2010 The prefab box is why you're not hitting the lows that loud. Prefab boxes are always tuned higher. Prefab boxes I use to have for my 10s were tuned at like 55hz. You would have to build yourself a different box to hit the lows better. For doing the big 3, Use This Link Quote 06 Mini Cooper S Sundown, SoundQubed Cadence, XS Power 151s Sealed 155s Outlaw Windshield @ 37hz Link to comment Share on other sites More sharing options...

kl0wn Posted January 18, 2010 Report Share Posted January 18, 2010 For using a program to help you build a box, use Torres' (ExpoSport) If you are more of a visual kind of guy, you can use RE's Enclosure Calculator to see it, then just take some of the measurements you use on that calculator, over to Expo's. RE's works just as good, but you have to calculator a few things yourself, Expo's will do it for you.

My OEM alternator is a panzy 70 amperes (12v). What gauge wire would you recommend to use for this setup? My lights currently do not dim even with the OEM alt. and OEM big 3. I was planning on using a 300 amp. fuse also but what with the small amperage that might not be necessary to use something that large. Hopefully this is the last of my questions, just want to get it right! Quote Link to comment Share on other sites More sharing options...
kl0wn Posted January 18, 2010 Report Share Posted January 18, 2010 When doing the big 3 you want to use a pretty big size wire to have less resistance. I would use 1/0, and a 300 amp fuse.
