I'm building a box for my friend's Fosgate t2 15. How much port area per cube should I have? the box will be tuned to 33Hz. Thanks in advance...
u can build it at 4.3cubes before displmnt. and 49"sqr of port with 22" of port length, that sounded GREAT! hard for alot of subs to sound better than this sub in that enclosure!!

Are your decks RCA grounds loose?
Are the amps grounded to one location?
Are the grounds sanded down to bare metal?
Have your tried swapping RCA wires?
Have you checked you voltage with a DMM at the Amp, battery (front/back), also the ohm load?
yea all those basics are done, except for swappin rca, and checkin the voltage directly at the amp. as for the ohm its down to 1/2.
-
So there is a popping while playing music ?
Are the subs reaching mechanical limits ? Also... unhook the remote knob and see if it stops.
im pretty sure the subs arent reachin its mechanical limits because it happens to soon in volume increase, the subs are 18s btl. it was doin it without the knob thats why i hook up the knob, so that i can have somewhat control over that pop noise while drivin. yes it happens with music.
-
Can you video it ?
i can try video it with my cell phone that the only recordin option but loadin it to the computer is what gets my sometimes. but ill try cas i really want to get this corrected.
-
Need some more information about when it occurs.
it occurs even before i can set the bass knob to half, gains not even close to half and it does it, voltage no lower than 12.6 at FULL tilt.
-
i was thinkin low voltage was the part of the issue in my boy jeep with the two 3k, but in the other vehicle with the 3.5k the voltage doesnt drop below 12.6 and the poppin begin sumtimes even before the voltages reaches that low. this amp was from db-r so im thinkin that refurb wasnt a good repair. ill try some of you guys ideas and check the other things y'all listed also appreciate all the inputs
-
i've heard three sundown amps 2 3k and a 3.5k and they all are makin a pop sopund in the woofers, in different vehicle installs, and am not talkn about lower freguencies either am talkin about up in the 41-42hrtz range. so i wouldnt think sub filter. gains not set with an o scope but set very cautious.
-
yea man thanks, but how did u go about taking out the orange i thought about it but i dont have patience so i didnt want to ruin the lights since i paid 400+ for them(what a sucka). and couldnt afford or didnt want to afford the original envoy lights they cost 800 a piece because GMC refuse to sell them without the HID and doesnt sell aftermarket.
-
have anyone ever come across any aftermarket headlights for any jimmy or sonoma, i know they make for s10 n blazer but why never for the GMC. or even L.E.D backlights?
-
Ah - in that case Chris may have accidentally switched the plugs inside the amp. This would reverse them.
yea but am okay with that, rather than a completely defective rca outputs section. thanks guys for inputs!
-
Is the amp new ? Every one is tested before it leaves -- so I would suggest changing to a different RCA cable as a first measure.
i got it to work thanks tho. the rca inside of the amps are reversed so the inputs are actually the brgde in and out and vice versa. no it wasnt new it was refurb.
-
he wont be back till monday
and your amp isnt the 1st amp Ive seen do this when they built the amp more than likely they connected some wires to the wrong RCA input thats what jacob said last time I talked to him about the issue
aite thanks atleast dont feel lost in this experience by myself. ill contact him on monday
-
You should send Jacob an e mail.
But be patient, because he's off these days. Sundown is closed for a few days.
i guess thats my best bet to email jacob directly, il maybe do that 2morrow since todays a holiday.
-
What knob are you using? One shouldve came with the amp, if your talking about the gain knob.
[/quot
no not the gain knob, im talkin bout directly on the amps controls, low pass, sub filter. etc.
-
Is it set to master or slave on the switch?
there isnt a slave/master switch. its done thru rca.
-
why is that my buddies knobs on my on the amplifier wont work neither does the rca inputs, i thought the bridge section inputs was only for using slave and master setups, so why does only the bridge-in works, thats the only way the knobs on the amplifier begings to work. why is that?
-
rusty can bench over 5K
thanks guys really appreciate the inputs, ill go with the one that has been benched closed or at its rms power which is the hifonics, its for my buddies instal.
-
actually theres a new HCCA line that does 5k and 10k
id prefer the HCCA over hifonics myself
thanks alot but u guys are thinkin about the older hcca5000 that was a 25k rms, but the new one will b out dec. 18 or so and was told a while ago that its 5k plus and will have birthsheet testin available. so that seems like it would be a beastly amp.
-
which amp would be most trust worty to put out rated power as said to be? both amp for same price! advise is appreciated.
-
Next step for the Ho?? .....
wish they made that profile for 28s so that i could force it on my 00'blazer, and still b as low as i am.
-
memphis 16st-1000d or the J/L Audio 1000.1
the jl 1000.1 will definately do better they have a well rounded bass, plus give u full power from 1.5-4ohm and 11-14volts, trust me ive used them for my self. dam good amps thats why they cost!
-
why is everyone obsessed with this sub up port back ting, if usin large amount of subs yes, but two 18s do it at 12cft 170sq of port sub back port back guarantee 150s tuned around 36hrt.
-
THE L7S MIGHT BE LOUDER BUT THE BTL'S ARE WAYYYYYYYYYYYYYYYYYYYYY LOUD. I HAD THE L7S AND THE BTL'S, AND I WOULD GET THE BTL'S ANY DAY. THEY CAN BE RE BUILT UNLIKE THE L7'S, AND THE BTLS CAN HOLD WAY MORE POWER THAN L7'S SO MIGHT WANT TO GO WITH THE BTL'S. THE ONLY DIFFERNCE IS CONE AREA.
nope the kickers wont b louder, not with 3k+ per btl. BTLS!!

ok so this soundstream http://cgi.ebay.com/PREMIUM-SOUNDSTREAM-7-...=item5634c0d0bc

needed advice. we are now runnin RFt4000s but they arent aggressive enough in the 40hrtz range and i tink that mekin it even more difficult to produce a good score. its a wall with 4 18s btl and our best score is 155.4 at 49hrtz. i feel the amps are the step one problem. any othe4r amp suggestions wpuld appreciate the help!
