Ok so I just put my 2 obsidian 12s in my trunk with my bt-120 & zx1500 wired to 2 ohms,
My gain is only half way cause I didnt properly set my gains yet,
From outside the car you hear it from 50ft away, at 25ft you hear nothing but rattle from my trunk, wing & rear bumper.
I was wondering if I face them towards the front near the opening I have through my rear seats how much quieter this will get and if the rattles will stop being so bad.

Memphis, more cone area and more motor force

stinger makes an extended gm battery bolt specifically so you can add terminals directly on the battery. you can use one of those.
i definitely wouldn't recommend running an amplifier off of the stock fuse box.
I'm running a big battery then a amp, but does stinger have it on their website?
-
So for the past day I just drove around with it. No amp hooked up and now with the amp hooked up with the car running my front battery reads 14.1 and the rear is 14.08 at idle so I think all is good.
Only stock 105amp alt that's going bad for now so voltage drops to 12.6 at idle of 600rpm
-
Could it be that who I got the battery from had it on a trickle charge for a few months. I haven't really drove anywhere yet I only tested it after idle for a few minutes.. tommrow I have to drive 25 miles, after that if I tested it again do you think it needs to be charged a little?
-
Big 3 done yet? Grounds sanded? and IMHO make the run to the rear battery off the alt. How did you attach the terminals to the wire>pics?
.5v drop front to back with no load isn't a good sign
No big 3 done yet, with my car I'm not sure how I would do it, my grounds are sanded, I'm useing gold plated terminals that are crimped and soldered
-
I can't really run off the front battery post, its the gm one that locks into place so if anything goes in between it it won't screw on.
-
This is what my power wire is connected to in the front .

This is where my alternator drops off power. Also a very good shop around here told me this is the best place to run my power wire.
-
What wire have you got from front to back?
Knuconceptz cca 1/0
My ground in the rear is good also
-
Seems pretty high for resting voltage, load test it, make sure it passes. Might be overcharged. Sounds like you have a faulty regulator.
Load test the rear batt or the front?
& I guess I will see tommrow when I start pulling 1500rms at 2 ohms
Should I let them load test it at auto zone?
-
Can anyone answer this cause I'm kinda worried my rear battery might be bad
-
& off resting voltage is 12.88 in the rear
-
Ok so I just installed my rear battery its a shrunken bt-120. It reads 13.56v.
My front battery is a acid interstate, it reads 14.06.
Is this normal or is there something wrong here
-
You can get them new for $166 off ebay
The old ones, or for the new ones that 166 is without shipping
-
Just arrived today, going in tomorrow.

I'd say he can get a obsidian 15 for around 200 or less shipped.
The aq is good too though
-
if your budget is 400$ max than I would look at a E-12 or obsidian audio 12(if you can get it and not get raped on shipping) E-12 will run you about 110-115 shipped if you look at the right place.
Spend the 110 on E-12 D2
get the mb quart 1500 or a brz 1200. wire it at 4ohms not 1ohm. So you will get like 450 which is RMS for the E-12.
250-275$ right now
take the other 125-150
Order good OFC 4 gauge. Knu Koncepts Kollosus flex gets my vote...or Audiotechnix OFC(oxygen free copper)
Get enough to do your amp and the Big 3.
Use the leftover money to get some MDF and build a box exactly to spec...a ported box. Whatever you have leftover maybe invest in a Better head unit or some better Coaxials or components.
Just my 2cents and what I would do with 400$ ----IF this budget is exclusively for subs amps alone than I would get two e-12s a brz1200 and wire 1ohm.
I like this idea also, but instead of just 1 12. Do either 1 15.
Or 1 18 same wattage like obsidiian audio if you have the room. They are all just asking for 600rms
-
So I saw this ad on long island ny, selling 4 new cvx 12s dvc2s for 180. They go for like 225+ online.
The guy I hear is negotiable and even more if you buy more than one.
-
alright. for subwoofers, you want a monoblock (1 channel) amp. in very rare cases it is better to use a bridged 2 channel. but 95% of the time, you want a monoblock
ported boxes, when built correctly, let the woofers play better than if in a sealed box.
clipping is the #1 killer of all speakers. i dont give a fuck if your speaker has a uranium phosphate iodine cooled voice coil. clipping will eventually fuck it up like a curb stomp.
you dont need a bass processor.
i'd throw away, or sell, that pyle (of shit) amp you have.
lastly, how much money do you have to spend for subwoofers/wiring/amp/box?
My budget is around 400$. Does the amp really make a big difference? It probably a stupid question but I have not really looked into amp reviews and such.
Junk the amp, a mb quart would be a lot better than Pyle and a 1kw one is like 79$ off sonic
-
What's the xmax on these? I wish they still made them in the 15" s I would of considered one
-
Yea so just bought a 3.5 cube dual 12 box tuned to 32hz...& a shrunkien bt-120
A friend of mine that use to have 2 lvl 4 12s
bought?
...from where?
-
Ok so in about a hour I plan on ordering 2 obsidian audio dvc2 12s. They will be ran off a zx1500.1
Just trying to see if anyone is against them or has had problems with them, they will be seeing around 750rms ea.
Not sure if I should just get the dvc4s and buy a hifonics brz1200 instead and run them at proper power?
Pardon me for sounding like a dick but if you want obsidian audio then why do you care what others think bro? If it is something that you want then fuck what every one else thinks.
Well wanted to see if there was any known problems
-
try it both ways and see which you like better
Just ordered them, wonder how long they'll take to get here, says there shipping from north Carolina and I'm on long island
-
A bit tight.. best of luck.
not really. 1.75 per sub is fine.
and OP, excellent sub choice. they'll probably beg for more power though
I'm wondering if when I get them if I should just invert them so they get 1.91 ea..if that would make a difference
trunk rattles like a mothafu**er
in Subwoofers / Enclosures

Equally as loud then?, less rattle?
