JakeW Posted September 16, 2020 Report Share Posted September 16, 2020 Working with 1.2Giga, and he’s a solid dude and tons of help. Narrowed it down to adding another DC 12” lvl 4 12, 1500rms. Gonna wire the 2 2ohm DVC in series, with a taramps 5000.1 2ohm amp, mounted on the rear wall behind the 40 side driver seat. Putting them in a “vented” fox acoustics box, which just has openings not actual ports, so I’m considering plugging them off. 1 run of 1/0 from front battery to (somewhere mounted) shuriken bt-80 battery. Will have dual 1/0 runs from it, into the amp, and dual grounds from the amp. I’m looking for any hints/tips/tricks from installers, I’m thinking an smd dual fuse block for the dual runs in the back. Anything else I’m missing? ‘16 ram. Net Audio. Taramps. JL. DS18. Fox Acoustics. XS Power. 226.08” of DC Audio blue carbon fiber. Link to comment Share on other sites More sharing options...
JakeW Posted September 17, 2020 Author Report Share Posted September 17, 2020 Changed plans! Adding another smart 3 instead.... anyone have 2 amps, with a universal bass knob on the first amp? Will it control both amps? ‘16 ram. Net Audio. Taramps. JL. DS18. Fox Acoustics. XS Power. 226.08” of DC Audio blue carbon fiber. Link to comment Share on other sites More sharing options...

Pac-lc1 is pretty popular, I bought one to control my two DC 2ks. - You will just hook this knob inline to your RCAs. Basically buy another 3 ft RCA to plug into back of radio, run to input of LC1, run original RCAs from output of LC1 to amps, then split the RCAs using a splitter to each amp. - Alternatively you could pass-through RCAs (I eventually will test voltage to see if the myth that using path-through RCAs drops your voltage...) https://www.amazon.com/PAC-LC-1-Remote-Amplifier-Controller/dp/B0002J226O -------------------------------------------------------------------------------------------------------------------------------------- I hope you were mistaken when you said "Gonna wire the 2 2ohm DVC in series," With two amps/two subs that would put your nominal impedance at 4 ohms, see below: You want to wire each sub in parallel to achieve a 1 ohm load, see below: Impedance Diagrams: https://www.the12volt.com/caraudio/subwoofer-wiring-diagrams.asp ---------------------------------------------------- "I’m thinking an smd dual fuse block for the dual runs in the back." Side note, love my SMD fuse holders. Also come in any color base/plate you could fancy 🤔 but they are expensive, only downside imo.

Yes I have a bass knob, here is how it’s wired- I have a PAC converter for my rca signal, the knob is after that, then the rca from the knob is into a 2-1 since the smart 3 has only 1 rca in. But how do I control the other amp? And the comment on series, was for the 2 subs. Having only 1 per amp, they’ll be 1ohm each ‘16 ram. Net Audio. Taramps. JL. DS18. Fox Acoustics.

Having only 1 per amp, they’ll be 1ohm each If the amp only has one RCA in you could ditch the 2 female - 1 male and just plug each of the two RCAs into the amps. Otherwise a cock box or more splitters are in order "And the comment on series, was for the 2 subs. Having only 1 per amp, they’ll be 1ohm each " If you wire one amp per sub in series you will be doubling impedance, this will be 4 ohms. Parallel halves impedance, thus 1 ohm.... see diagram above. - SMD Tool Map (2022): https://www.stevemeadedesigns.com/board/topic/220267-smd-tool-map-2022/ My Port Size Calculator (in progress): https://www.stevemeadedesigns.com/board/topic/217087-port-size-calculator-in-progress/ Common Port Walls for a Slot Port: https://www.stevemeadedesigns.com/board/topic/217076-common-port-walls-why-it-matters-to-your-box/?tab=comments#comment-3240313 Link to comment Share on other sites More sharing options...
JakeW Posted September 17, 2020 Author Report Share Posted September 17, 2020 Right! In series was for 1 2ohm amp, & 2 2ohm subs. not 2 separate 1 ohm amps sir. 2 amps I will wire each sub to 1ohm. And the L R rca have no designation on what they control? I could just do 1 & 1! ‘16 ram. Net Audio. Taramps. JL. DS18. Fox Acoustics. XS Power. 226.08” of DC Audio blue carbon fiber.

JakeW Posted September 17, 2020 Author Report Share Posted September 17, 2020 With the smd fuse block, how did you go about crimping your 1/0? That’s why I haven’t used that style fuse block yet, ‘16 ram. Net Audio. Taramps. JL. DS18. Fox Acoustics. XS Power. 226.08” of DC Audio blue carbon fiber.

I see our disconnect. If you have 1 2 ohm amp you will wire 2 2 ohm subs in series / parallel not just series. RCA wise I am almost positive it doesn't matter in the case of a monoblock amp, single channel. It would matter if we were talking about a 2 or 4 channel amp because you would lose the ability to differentiate between left and right signal... yada yada... There is a case to be made about pre-amp voltage coming out of your head unit, but I don't see that being an issue on any quality head unit / rca cable. The gain is there for a reason, it adjusts the voltage to the correct floor, regardless of rca voltage. 37 minutes ago, JakeW said: With the smd fuse block, how did you go about crimping your 1/0?

It takes some playing around to get the correct die fitment but super easy once you do. Can do smaller 8 gauge to 1/0 + - Only tip I have for you is to use some kind of dielectric grease where the terminal meets the wire/jacket so when you put the heat shrink on it will form a better seal against corrosion. If you get tinned ofc wire this is probably unnecessary.
