^ that sub eh good.. offer me a price, i'll take it off your hands.. lol

hehe seems like firewall has one up for grabs

[nervewrecker]

sold like hot bread long time.

i did one door this morning with the dynamat sound deadener. not the neatest work but here goes.

[speedmelter]

covered the outer and most of the inner side of the inner panel. and almost the entire inside of the outer panel. used exactly 2.5 sheets. oh and the inside of the door upholstery i put quite a bit of squares about 4 by 4 inches.

[speedmelter]

got a box today. and its ported.

[nigel1977]

What are you planning to do with all the openings in the door?

[speedmelter]

idk do i have to seal it? what is the usual thing to do?

[nervewrecker]

Seal it as best as you could and reinforce that metal with a viseoelastic material.
You trying to get the midwoofer to perform like its in a sealed box.

[3stagevtec]

idk do i have to seal it? what is the usual thing to do?

It would help with mid bass response and reduce rattles on the factory panels.

[speedmelter]

can u guys suggest a material to use for this? i can get some sheet metal and cut it to shape but how do i attach it.

btw got another piece of equipment today. an xs power supplemental battery from our dealer right here 2lo2flo. thanks man!

[nervewrecker]

You could use any solid sheet and dampen over it.

Thanks for your purchase!

You have a pretty good build. That sub is Awesome

[speedmelter]

thanks man. hopefully i do it some justice

hi guys. i havent done the perfect install as yet with my equipment because i wish to upgrade my ride in the near future and want to do the proper install into that. my journey to achieving nice sound has been a bit slow but so far things are shaping up as it is.

i had gotten my alpine f6 with an issue and i will be sending it back to repair. i was too impatient to wait the time so i just went ahead and bought another f6, which is playing really nicely now. so as it stands i would have 2 4ch amps maybe by christmas depending on how long alpine take.

so i was thinking. this 15 inch sub is being underutilised severely. i have two options in my head if i want to increase the midrange. i was thinking of say 2 4ohm beymas and 2 1 inch drivers on the backdash... but idk if i want that much. i searched alot on forums of builds where people used the subwoofer i have and i found a really nice one where they used a 3way active front stage with the jblw15.

i like that idea much better than the pro audio on the backdash, so was wondering if going that route would be hard and what characteristics should i look for in a car to house a 3 ways system. is it customary to place midrange and midbass in the doors say in a special made thingy?

my current midrange speaker is the xs components where the midbass is more of a midrange, what midbass driver could i look into to compliment that in a 3 way set up?

im thinking of the teanna jk cefiero as my upgrade.

[nervewrecker]

3way comps not made for the kind of 3 way men 3 way here. Its built for a different purpose and tuning it is harder from what I understand as opposed to the normal 2 way. The hardcore sq men might be able to better explain.

Those id xs speakers supposed to be on par with my jbl and these do play midbass. Trust me on that.
You may be doing something wrong to not be getting midbass. Hpf them set right? Doors sealed?

[speedmelter]

they are playing midbass but the sub is set like 4 db lower than the midrange and is very tame for it to sound balanced. if the 3 way is opening a hard can of worms then ill put the idea out and just sell the extra amp or sum. cuz id then have to buy a 360.3 as well to do the 3way. just exploring ideas.

currently i have each side of the passive xover on a pair of channels each so they are supposed to be getting 300watts rms per side.

[speedmelter]

im also using an in dash epicenter .. so didnt want to do that but most of my taste are old music and the bass sound terrible in the 28hz tuned box. but there is an on/off switch on the epi to activate it or deactivate.

[nervewrecker]

You can play with the slopes a bit and see if you can change your response curve.
You sure those doors sealed off? 300 watts is loud!

You can go the pro audio route and sound very good you know.

Why epi? 0.o

[speedmelter]

cuz the songs dont have natural low bass i guess. but it is making a world of a difference.

the pro audio route is sounding like a much easier option. ill have to figure out a way to do it in a way where i could only turn it on when i want to.

i have this kicker product, it like a pre amp but doesnt have line drive. if i use it, would it be sufficent processing to play rear midbass and drivers?

[speedmelter]

[3stagevtec]

^ That's an EQ.. (just because it's a 1/2 din size doesn't mean it's automatically a preamp.. lol).

I'm not fully following the thread, but it may not be necessary depending on what headunit you are using. The built in EQs in most decent headunits will usually be sufficient imo, too much added components is not always a good thing.

Also, check what is the max input and output voltage on the Kicker. Some of them can have low line drive that wouldn't be good.

[speedmelter]

yea that piece of equipment is pretty much junk in today's world, looked it up and i think its from the 1990's. the max output voltage is 2v, it doesn't give any added line drive lol. i use a pioneer prs80 for headunit.

if i do this

4ch amp (1) , ch1&ch2- to left and right front doors. i will get 150 watts at the 4 ohm per side. and
send it to each passive xover.

,ch3&ch4- bridged to a pair of 8 ohm drivers. i will get 300 watts at 4 ohms to the two
drivers.

4ch amp (2), ch1&ch2- bridged to one 4 ohm beyma pro audio 8 inch, should get 300 watts to it.
, ch3&ch4- bridged to a second 4 ohm beyma pro audio 8 inch, should give 300 watts.

sub is already taken care of on the monoblock.

question is i would have to forfeit the network mode on the deck?

i want to always have the front doors in the stereo mode so i will use the front outputs in stereo to play ch1 and ch2 on 4ch amp (1) with a full pass signal.

i will only remain with one pair of output for the rear, which i could split into two but one of these have to be hp at abt 1200 hz to the driver units, do i need secondary equipment say a crossover for this? besides building a passive for it, is there another solution?

if i end up using an electronic xover, for this setup, have i essentially wasted the deck?

[speedmelter]

hey guys,

its been a while since ive been trying to upgrade my system. In a battle to balance loud with quality ive reached this point. thanks to u all and this evil hobby ive spent all my designated spending over the last few months on car audio equipment... sigh... lol

i think i might be crazy but this is where i stand for the moment. im going to try something for the while and for the experienced guys, please tell me if this makes sense...

i have now 3 pdx f6 and one m12... long story...

i bought the alpine PXA H800 processor, would get it within the next two weeks...

im thinking of a sql install using the above equipment, in a strange config..

i see a suggested config. using the processor to be a 3 way front and a rear. subwoofer being externally processed

im thinking of using that configuration to run a 3 way rear using a lower band of a pair of beyma 8g40, mid range of a pair of 8mi100 (i happen to already have these) and well a high of some decent pair of drivers.

and the "rear" as a full pass to my front door 2 way components. image dynamics xs65

and the sub straight from the deck to amp..

can this reverse configuration effectively be tuned to sound "correct"????

i know for now im wasting precious equipment, i hope to build a pure sq system some day but im still in the learning/ experimenting stages.

but... is is worth a go?
