smoke03 Posted May 20, 2007 Report Share Posted May 20, 2007 Im building a new box and ive got a few questions, I want to put 2 12" Kicker CVRs in the box firing down but i also want to put to 5 1/4 speakers (also kicker) in the front of the box firing forward. Will there be any intereferance between these four speakers? Should I build a separate chamber for the 2 speakers? the speakers and subs will be running off of 2 separate kicker amps if this makes a differance.

WidowKiss Posted May 20, 2007 Report Share Posted May 20, 2007 you have to build separate pockets (boxes within the sub box) for the 5-1/4", otherwise the subs will blow them in short order Quote Link to comment Share on other sites More sharing options...

NoLegs Posted May 20, 2007 Report Share Posted May 20, 2007 Are you just trying to relocate your rear stage, because the stock rears are too high (as in the location)? Quote Link to comment Share on other sites More sharing options...

Chevrolet SS Posted May 21, 2007 Report Share Posted May 21, 2007 no im keeping my stock speakers in im just putting 2 more speakers in why? front stage is where its at Quote Link to comment Share on other sites More sharing options...
mastergunsx15 Posted May 22, 2007 Report Share Posted May 22, 2007 hey man i would suggest working on your front stage mainly and using rear fill if and only if you must. all adding better speakers in the rear with the stockers will do is 1: mess up your imaging, pulling the sound to the rear of the truck and down and 2: not sound that great with the difference in power along with positioning of the speakers odds are, they will be louder than stock. again, i would put in a good component set up front, amp them, and use all the area in the rear to build a nice ported enclosure for the 12s if you can spare the room or a nice sealed box with amp rack or something of the like. good luck though man Nick Quote Link to comment Share on other sites More sharing options...
misterp Posted May 22, 2007 Report Share Posted May 22, 2007 Couldn't agree more. You're going to either muddy the SQ or diminish the bass volume doing this, you will be introducing waves almost 180-degrees out of phase to the woofers. Fire everything you can off the rear wall of the truck, and dynomat the hell out of the rear wall while you're at it. Mr. P. Quote Link to comment Share on other sites More sharing options...
smoke03 Posted May 23, 2007 Author Report Share Posted May 23, 2007 hey guys thanks for all the help and i think im gonna take your advice on not putting the component speakers in the box. If its going under my seat should i use a sealed or ported box?...do i have room for a ported box? Quote Link to comment Share on other sites More sharing options...

Fire everything you can off the rear wall of the truck, and dynomat the hell out of the rear wall while you're at it. Mr. P. I agree with the guys here ... as far as a sealed or ported box for the subs ... If you put the subs inside the box, make sure you design the box to the air tolerances of the sub. IE - If the sub calls for 1 cu. ft. of air behind it ... make sure that chamber is exactly 1 cu. ft. Especially if you decide to go sealed. Sealed boxes with the proper amount of air volume behind the sub will hit very hard ... if that's what you're looking for. If you want to harness the much lower frequencies ... ported is the way to go. And, if you decide to go sealed ... make sure to caulk all the joints and corners inside the box. This will keep the air leaks away ... I had a real nice Q-Logic box in one of my old cars that was both ported and sealed. (Behind the sub was sealed, and in front of the subs was ported) ... that was a real nice box, and it sounded great.

mastergunsx15 Posted May 24, 2007 Report Share Posted May 24, 2007 the type of box that perk is talking about is a bandpass box...you definitely dont have enough room to build a proper bandpass box for the subs. as far as sealed vs. ported i will venture to say this: sealed generally allows for more power handling than a ported box but also lacks output compared to the ported. a properly built ported box will sound just as good sq wise as a sealed box. in my opinion, ported is the way to go but everyone has their own opinion on the subject. ported can hit just as hard, loud, low, and accurately as sealed provided it was designed and built correctly. either way you choose, definitely make sure you build a solid box. caulk the joints, use lots of wood glue, screws every 6 inches or so, and bracing if needed. good luck with your build man and let us know how it comes out.

Nick I definitely agree w/ mastergun ... but I've never seen a ported box hit harder than a sealed box. (Ported offers more "flex" than sealed does ... once a sealed sub hits, the vacuum from the sealed enclosure draws the voice coil closer to the magent quicker, and gets the sub ready for the next "hit") Could just be the experiences I've had ... possibly mastergun knows more about box building than I do ... When I built a box for my buddy's 12" Soundstream's ... they needed 1cu. ft. of air behind them, and 750 watts RMS, 1000 Peak. We built a sealed box to those specs ... and man, did they hit ... HARD. It felt like someone was punching you in the chest. (They were dual voice coil subs, though) Nonetheless, my buddy overheated them about a month later, and rolled his car not long after that ... so ... it ended up being a lost cause. But ... his system sounded wicked! Edited May 25, 2007 by perk03z06 (see edit history) Quote Link to comment Share on other sites More sharing options...
