Alex Coyne Posted April 3, 2015 Report Posted April 3, 2015 I sold my friend my HDC3 12 and Q1-1200.1 amplifier that where brand new (I'm upgrading my alternator and battery so I sold it to go a different route). No point in running a $250 sub on $900 worth of electrical He got it hooked up with custom box at 35hz and gains are set professionally. His 12 inch CVX on 750watts in a crappy probox was a little louder and he's disappointed (he figured a more efficient sub thats twice the weight and 500 more watts all in a proper box would destroy the CVX). I googled around it i've heard that the HDC3 are super stiff and get louder/lower over time. Would this break in period (soft parts/suspension loosening up over the next 3-5 weeks) cause a significant gain in decibels ? (any AQ or DD owners who can comment on this ?). I've seen people online say there getting 10-20 db increase over time while others are hitting 130+ straight from day one. I feel kinda bad selling him this and it not be as loud as expected (on a good note it sounds great on music, 10x better than his CVX sound quality wise)
Mustang2dakota Posted April 4, 2015 Report Posted April 4, 2015 The ts parameters of your sub change after your sub Is broke in. I have no personal experience with soundqbeds products but on their website they seem to make a point about their subs needing broke in. 2014 JKU Sound: pioneer xav-65 4 12in pioneer tsw3003d4 2 pioneer gm-d9601 (much more in route) General: 18in worx rims 33in tire stinger src bumpers light bars 6k hids 2in leveling kit 3.25in lift The Build Log: http://www.stevemeadedesigns.com/board/topic/195839-2014-jku-build-4-12s/

And how much port area takes a month they get very loud for 12s in the right box. dont push them to hard in till they get alittle softer i got 2 0f them right now on 4k and they bang More information for both of you (I posted this reply in another forum which i posted the same topic, here's the copy and paste ) My Reply: I'm having him send me pictures of the port and the amplifier knobs. The installer was a local store (three guys that run it privately) that deal mostly with digital design products/installs. From memory the box looked to be just under 3 cubic feet. I've seen in person three boxes (all pre-fab) and the port on this box was significantly larger (I'll have him send pictures) He had the port fired towards the license plate and then moved the port towards the left back tire (it got noticeably louder but still not loud enough). My entry level sundown E12 on 750.1 watts on 2ft prefab was about as loud as his current HDC3 12 (his CVX 12 in a probox was a small amount louder). Something is wrong for sure ! (sundown E12 on cheap prefab and CVX in cheap probox where both in the same area as his HDC3 when it shouldn't be close)
soundstream15 Posted April 4, 2015 Report Posted April 4, 2015 They need 14-17sq of port per sub. For 1200rms box should be 3.2 cubes net For 2k rms box should be 2.5 cubes net My bet is the box is to small...they love big boxes as well as port, I sold my hdc3s bc of that reason
bassaddiction Posted April 4, 2015 Report Posted April 4, 2015 how is the sub wired bc if its at 2 ohms that thing wont even move. also what is the lp set to
Alex Coyne Posted April 4, 2015 Author Report Posted April 4, 2015 Its wired to 1 ohm. Not sure on LP (i'm having him send me pictures of the amplifier knobs). For box it looks to be about 3 cubes total (I'll have him measure the exact dimensions
