used dc power engineering alternatotrs will they put out to spec?

with making my box for four 15 subs sounds great but i have a slot port at bottom of the box and when the bass hits hard the middle inside of box flexs and makes a vibe sound. how should i brace this with out change the tune of the box?

wire power and ground have other ppl used on the audiopipe 30001d?

i do have the subs now the specs on watts dont go down less your doing a big sealed box not ported. i was thinking about 20cf plus port what do you think? i was asking for help with the port square inch and depth of port i need help with tune part. i understand that the subs are not xcon or other brands that they sell. i have done some looking around and did a search on this forum and not every thread has to do with just xcon and other subs. so im asking for help because i know that you guys and lady lol know what your talking about on this forum!

how could i get better the xcon 15 is $380 each and my box they said make 14cf not 10?

first i have checked ssa and ai but i can get the 08 models two for 359 with free shipping! i do look around and kicker is saying 3.5 cf each then ports and subwoofer displacement . that will bring the box down pretty small for15s what do you think they should be at?

its not about the name of the subwoofer or company. if someone could talk to me about the box specs what your thoughts are on the BOX and kickers e mail thanks.

im thinking about buying four kicker l5 15 inch subwoofers. i sent kicker a e mail what size box i was wanting to put them in 16.04 cf inside. that would bring it to around 4.01 each subwoofer. i told them i wanted to port the box and they sent a e mail back this is what it said.shrink it down to 14 cf internal . this will have port and woofer displacement already caculated into it. give the box 160 square inch port opening and make the port 19.5 long into enclosure. seems to be to small for them what are you all thinking on this? what would that give the subwoofers after woofer displacement and the port they gave seems to small they also said it would tune it to 35hz

thats what im talkimg about i play music not just burp

you woild be surprised on how many ppl dont get ho alts

lol i get what your saying but i can run my audio loud and do it for hours and volts stay up and that makes my amps happy and my charging system happy and i dont have to worry about cooking my amps due to low volts or amps. i wish i could get a ho alt but i cant seem to find a place that makes one for my van mazda mpv 2002?

i get your point truly what you have said works out good. but to make the mtx push that air you still need lots of amp power and your alternator has to put out the amps. for them to be pushed that 25mm if you go and get 3 mtx 9500 and try to run 3000-3500 watts to them like they need to work to specs with lets say off a sundown 3500 amp and your only able to give that amp 100-120 amps out of your alternator its not going to hapopen. you have to have power to make that power and most ppl that do car audio dont put ho alternators most have 100-130 amp alternators

thats on a mic im talking about daily beating down the street! when your car is on and not just playing your music for 15 sec then turn off . it comes down to what car/truck its in and if the subwoofers are in your trunk or right behind your head and have been sealed off from back of car/truck! one 18 in a geo metro will bang look at the space you have very small car.

how would you get more sound from one 15 inch. that thing could jump out 40mm one way how is it going to out do 4 12inch subwoofers or 8 12 inch subwoofers. i understand being cool and being loud with one subwoofer but you can only do so much with one subwoofer!
