  3. Newbie question 12" Vs 15"s Help Please?

    A lot of it is in the box but smaller subs can hit "faster" due to less cone/coil weight. It also takes more excursion for them to excite the same volume of air as a larger diaphram though.

    Do you want it fast and hard (shakes your voice box) or low and hard (sucks the air out of your lungs)? I much prefer low since you are less likely to hear "voices" from the subs then.

  8. Am I doing this right?

    Pair of old MA Audio HK18's (quad 1.3 ohm coils each) in ~13 cubes at 30hz.. ~800w (original? Kicker ZX750.1 @ ~0.7 ohm). With doors open on music (Cubanate - Human Drum) the meter said 140 on the dash before the amp blew the 60A worth of fuses it had lol ;) Truck was off btw so amp was only getting about 12.6v or so of a single battery.

    Coils are paralleled on each sub then series between the subs to the amp, mathematically works out to 0.66-0.75 ohms, DMM says ~1.1 ohms. Havent done any "exact" measurements though.

    Good start anyways until my big amp (Fusion FCA-4000D) arrives I guess ;)

    Pic or two up tomorrow if I remember, its dark out right now ;)

    Interesting, was wondering what happened to them. Thanks.

    These are before Jensen/Dual though I think. As to blowing them up, i'm not too worried on that front. I'm sure they will last me long enough or i'll pick up some LMS drivers before then.

    Anyone got a clue what kind of box volume I should be looking at for them? I read somewhere that about 6-7 cubic feet each is good but havent seen a spec sheet so its hard to tell. Also looking to tune them as low into the 20hz range as possible as I have a thing for low frequencies.. lol. Dont worry though, the current train of thought is to make the port changeable so I can swap it to 30+ for racing or whatever ;)

    Thanks

    u know ma got baught by the company that owns jensen and dual sooo i mean that speaks for itself + their repair dept. sucks if u blow it up after warranty because they do no repairs unless its under warranty and told me they would not sell parts.... :unknw:

    I have one right now and am considering putting two (or just sticking with 1?) in a 1996 Chevy 2500 extended cab to replace my 4x Kicker 10's (2 2005 L5's and 2 ~2001 L7's lol).

    Unfortunately I cant find any specs for them on the net anywhere other than the coil ratings (5kw rms, quad 1.3 ohm titanium 4" coils). So should I stick with the MA('s) or go a different route? Currently i've got a single Lanzar Opti2000D, might get a second.

    Pics of the 4 10's just for those interested ;)
