help with new sub setup

I still say your clipping them.. Most subs dont just blow like that

you need to line match the amps so that they are putting out the same power to each sub ,and use a ported box.the level 4s will be just fine ,but if you want to leave room for more power then do the level 5 upgrade

im hardly a noob, im 30 yeaars old and have had systems since i was in high school, from old series rf amps, phoenix gold, ppi, alpine v12's, run diamond components, idsubs, u name it

Im right there with you but sometimes I still do dumb ****

ive also had the amps backed down a little bit, its more or less due to the fact when i get in the car i usually beat the crap out of the subs for a good hour or more straight, the coils just unseat and burn up cuz the kickers cant handle being run for one or more hours continuous day in and day out

you should prolly install a volt meter on the rear battery ,especially if you are playing you system that loud for that long

what do you mean "amps backed down"??? L7's are not crap subs... their not my favorite, just cuz of their price point, and what you get for the price.. but by no means are they crap subs... and there is no way you should be blowing them with that much power.... not even running them for a couple hours. one sub blows, i say its possible you got a bad sub... 2 blow at different times, i say your clipping them with inproper tuning

i set my amp by finding the clipping point and turning the gain down slightly from that, giving me my max gain level. i then turned the gain down a little bit more so that i wouldnt have this problem. my head unit is set at 25/35, bass at o, and sub level at 5/15

hes running 2 alpine amps at 1300 watts rms each and 4 L7s in a sealed box

To 4 L7s so they are already a bit under powered

did you set your amp with the sub level on your HU up? cuz that will cause the clipping point on most amps to drop

an L7 handles 750 at 1 cube sealed, 600 at 2.25 cubes sealed, or 600 in any ported box, i was running them at 1.5 cubes sealed at about 650 rms, which at 1.5 i imagine the handle around 675

yea, im with mast and haze on that. I had L7s and they took every amp i put on em. from JL 500/1 to kicker zx1000 to about thirty minutes of a friends old school rf1500bd.

and i beat on my subs all day!!! that L7 can def take a beating. not the best sub, but i doubt u blew it from too much power with those amps on all 4. even with one of those on each i think theyd still take it for a good bit.

Who told you that? Rated power doesnt change by box size, It just takes less power to get loud in large boxes in SOME cases.

yeah i still think the new L7's are crap, i had an old school L5 in an integar getting 750 watts from an alpine v12 in a ported box, and it took 3 years to blow. they dont have the same build quality

in the manuals when u buy new, they put all of those specs in there. but L7s will still hold a good bit more than 750 in almost any enclosure
