I vote more cone area.
(2) 15" SR's?
-
IMO the box is the most important factor in deciding how loud a sub will be. Based on my own trial and error. I went from one ported box hitting 138db to my fourh box hitting 148.8. All with the same amp/sub combo. Cant emphasis enough, test, test, and more testing. An experienced person who know what their doing will almost always have the louder system versus a beginner.
oh yeah i know that. i know someone that specializes in making custom boxes. i know what you mean by testing and testing. i had a type-r 12, it been through 4 boxes. it went from ok loud to really loud :]! i just want other people's opinion. i cant buy all the subs at once. people are so helpful on here <3. thanks.

Amp: kicker 750.1- 350rms @ 4ohms/750rms @ 2ohms
- (1) re audio SE 15" 600rms/1200max
or
- (2) re audio SR 15" 300rms/600max
or
-(1) alpine type-r 15" 750rms/2000max
what do you think which set of sub/subs will be louder? im planning to have it in a custom ported box. thanks alot people!

take a piece of wire (any wire as long as its copper) and twist it around the negative shield of the rca's on the headunit itself then screw it securely to an existing screw on the outside of the headunit
copper wire, will speaker wire work?
"twist it around the negative shield of the rca's" how would the wire stay on the shield?

I use this stuff called goop from home depot works great and I never had a dustcap pop off again after using it.
really ill check out that glue. the only thing im worried is when i press down on the cap, the glue will smush out and it will look ugly. you know what i mean? got any tips? thanks.
-
i had one pop of out of 4 and that was user error (not enough epoxy)
just make sure you mix that shit up and be somewhat generous
alright cool ill keep that in mind.
btw, what kinda alt you got?
-
ca glue would be best bet but its pricey iirc
but that epoxy worked fine no problems?
-
5 min epoxy worked for mine
really? i got some of that. a buddy of mine told be CA glue would too? thanks.
-
what is the best glue for a dustcap? my sx 12's dustcap it not glued down to the surface.
-
Trying grounding at the Deck first.
how exactly would i do that?
-
Ground your RCA output at the deck (more than likely this is what it is, happens all the time)
Try a different pair of RCAs
Make sure all grounds are sanded down to bare metal
my deck and eq are not grounded on the car's chassis, the ground wire from deck and eq is wired up with my car's ground wire harness. i used a crimped connector. you follow me? i couldnt find an area to ground both devices.
-
Move any RCA cables away from the power wires. Re ground (sand down paints and make a good connection) bad quality RCA's can sometimes cause this noise if they arent insulated good. like hone audio rca cables are a no go in cars. usually not enough insulation. (rubbers etc)
im thinking it may be the RCA's. they are rockford fosgate punch, but they are really old. i hope its the RCA's.
-
are they ran near the power wire, and what brand deck do you have ?
can bad quality RCA's be the reason for whining noises?
-
Seems like you got your answers imupabove. Anymore?
umm pretty much thanks people.
150 amp anl fuses will be fine? 1 for the alt to bat+ and 1 for the hot wire from bat+.
both amps total up to 120 amps.
-
thanks already saved that topic :]. so just follow each step and i will be good right? thanks again!
-
never did it seeing as how i dont get voltage drop anyways (only on idle but thats a different story)
and it would be a good idea to fuse between the alt to bat+ rihght?
-
simple answer that has been said hundreds of times.
yes
did you do the big 3 on your car? how were the results?
-
so by doing the big 3 it might* get rid of dimming/voltage drops?
-
Single ought. 1/0 or 0/1. Gotta do big wire. That's why it's called the BIG three. lol. The bigger the wire the less resistance. The more power is delivered to the amp from the power wire. And the more power returned to the battery through the bigger wire on the grounds from the big three.
okay but having a thicker between the alt and the bat+, wouldnt it drain the crap out of my alt?
-
I told ya Big 3 is the cheapest and quickest. All you need is 10 or 15 ft of wire and 30 min. Let's see what everyone else says.
would 4 gauge be fine?
-
So many threads.... Anyways, Big 3, power wire, and ground wire in at least 0/1. If you don't have the funds for a new alt. then a 2nd battery. You should be fine with that. Also, get rid of the cap.
so your saying to do the big 3 (4 gauge or 0 gauge?) and get a 2nd battery (what kind exactly?).

car: 1993 camry
system: kicker zx750.1 powering a 12" alpine type r, kicker zx350.4, rockford digital 1 farad cap, and using 4 and 8 gauge wires. stock electrical, 70/80 amp alt and a duralast battery >.<
i do get dimming and voltage drops, that is if i put the gain up a bit. the more i back down the gain the lesser i get dimming, regardless i still get the same results.
i would like to know what would be my best move? save money for a H/O alt? new battery? big 3 first?
thanks alot people. peace.

hey if i got a re audio SE 12 (600rms/1200max), what would be the difference? powering it with a kicker 750.1
oh btw this is the box im planning to put it in: http://tinypic.com/r/9tojfl/6
-
are they ran near the power wire, and what brand deck do you have ?
no they are not. its an alpine ida-x200

need help on the electrical

current system: Alpine HU, Clarion EQS746, Alpine Type R 12" in a custom ported box being powered by a Kicker 750.1, Kicker 350.4 powering Alpine and Polk Speakers, Rockford digital cap 1 farad, big 3 done in 4 gauge, stock battery (Duralast
), and stock alt. (70 amps).
at idle my volts sit at 14.8 and for some reason when i start driving it goes down to 14.5-14.6(before big 3 idle was @ 14.4-14.6). i do get voltage drops down to 11 volts on some songs/full tilt, but i think the big 3 helped out quiet a bit. before the big 3 the volts were worse. every time i see the volts go below 12 volts i back down on the sub volume on my EQ and it sounds pleasing to me.
i was planning to upgrade to a single 15" or 2 12s but i might be in the same situation due do my electrical system. dont get me wrong IMO this 12" is pretty loud for one 12" ;]. so should i invest in a batteries and a H/O alt.? id appreciate it if you can be specific on what brand of batts and alt. thank you for your time people.
