How to hook up two amps to one RCA Jack. July 9, 2018 by Paul McGowan. As an example with 3 amps and a bunch of speakers: Input RCA goes on the first amp and from it's loop connection it goes to the second where the story repeats. So all amps are already on the same input ;) … Is it Ok to split the out from the Pre-out (using, say, an RCA with a piggy-back jack on it?) If an amp has the ability to select one input as the source for all inputs then only one pair of RCAs connected to the head unit pre-amp outputs are necessary to provide the signal to the amp. New comments cannot be posted and votes cannot be cast. I've been told an electronic crossover will work but all that i find are even in and out. I have been told that I shouldn't split the XLR out, even if only one amp … Please refer to the links below for basic starting information. If you want to use a single preamplifier to feed two separate power amplifiers, how do you properly split … Multiple Amp Wiring In terms of amp wiring, that means getting your power straight from the battery. Right: An RCA Y adapter that can be used with a line level converter to connect to a subwoofer with a single RCA input jack. It's typically a total non-issue to do so. Low-level inputs aren't particularly dependent on current and voltage is constant throughout a parallel circuit. The best way to wire multiple amps … are there any that could split … Depends on the amp. 1 Amp for powering my sub. Unless the amplifier has an active crossover I would avoid this, as it's going to let a full range signal through. I know I won't have fade, but the car doesn't have a back seat anyway. Assuming that the stereo has only a pair of RCA outputs and you require to feed 2 amplifiers, the basic procedure would be to split the RCA pair.This could be acieved with the use of a 1 male to double female RCA adapter as shown below. You can split one output to supply a signal to all 5 channels. Sub-bass frequencies would … Virtually all consumer amplifiers have on-board crossovers. I have a 4 channel amp to run them (with the extra wiring) and I'm planning to install it soon. You don't need to hook up one splitter to the other. Does Ratshack sell anything to split both, or would i have to just split each RCA … inSync reader Robert B. asks, “I was wondering how much integrity an audio signal loses when split via a Y-connector.My dilemma is that I have stereo outs from my mixer that I want to send to two separate stereo amps… Before getting my current dac (dac-19 multiple outputs) i needed to run one rca output into 2 amps... i used one of these to swtich back and forth for awhile, given you can only use one amp … A good solution of splitting auxiliary signal to more mini amps using headphone amplifier - splitter. Say your stereo only has one pair of outputs, but you want to connect to a 4 channel amp with 4 inputs. You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra planning. The former is the most simple, convenient and space-saving option, p… But if you’re reading this before you’ve chosen the two-channel amplifier needed to drive your system, you have an important decision to make. How to split the preamp output Subscribe to Ask Paul Ask a Question. A “y” split from your AVR to both the BFD’s channels could get you a total of four outputs. Do you go for an integrated amplifier or separate pre/power boxes? Press question mark to learn the rest of the keyboard shortcuts, 2 Eclipse SW-8102s, V2604/4 Eclipse SW-8102s, Sundown SAZ-1200. Alternately, you could set your amps for parallel mode and daisy chain the inputs from one amp to the next (i.e. Radio --> Pie Adapter --> RCA Inputs ---> SPLIT --> Two Devices Would there be a noticable degredation in sound quality? I have a good Pioneer head unit with one set of RCA hookups . I have an older head unit (Alpine 7180S) which I think the preamp is broken or disabled somehow, but it has a single pair of RCA outs labelled "rear" that do work when hooked up as an input to my home stereo. While most newer decks have built-in crossovers as well, few amplifier manufacturers are going to make their amps incompatible or difficult to use with the many legacy decks that don't. I do have pre-outs and RECORD outs on the Parasound Halo that could send signal to a couple amps but that would be like … Note: only one amp at a time will be turned on. If it doesn't have that feature then multiple pairs of RCAs connected to the head unit pre-amp outputs or y-splitters would be necessary to provide signal to all the channels needed. Many multi-channel amps have the ability to use a single pair of RCA inputs to provide the signal to all amp channels. For The Car Audio and Video enthusiast! or a split … By splitting the signal from the head unit, you're also dividing the voltage by the number of amplifiers you're using. 1/ if one of the amps has a dedicated line level output then you may well be able to wire the CD player into that one and then using a pair of phonos, send the signal out to the other amp. It's necessary to state that a particular unknown amp may or may not have the capability, but incorrect to generalize that all amps are designed either way exclusively. It's a touch pedantic. If an amp has the ability to select one input as the source for all inputs then only one pair of RCAs connected to the head unit pre-amp outputs are necessary to provide the signal to the amp. speaker wire input ==> converter ==> RCA output). This is likely exceptionally true of 5-channel amps as they are primarily designed to be the center of a complete install, one which will need some form of crossover virtually every time. Is there any reason I shouldn't split them with RCA splitters to input them to 5 channel amplifier? This is the best way to keep your signal strong, without any losses!The splitter is powered by 12V DC so it will deliver the same amount of signal to all amps.Headphone amp splitter link (model 1):https://s.click.aliexpress.com/e/_AAfiLZHeadphone amp splitter link (model 2):http://s.click.aliexpress.com/e/_sXHunvHeadphone amp splitter link (model 3):https://s.click.aliexpress.com/e/_ABmwAXJack 6.5 6.35mm Male Plug to 3.5mm Female Connector:http://s.click.aliexpress.com/e/_saDknvThis video contains affiliate links, which means that if you click one of the product links, I'll receive a small commision. The signal is measured in volts as the amplitude of the signal is the significant factor concerned when looking at amplification. Hi and welcome to JustAnswer, Initially, pls confirm if the stereo has "one set of RCA inputs" or "one set of RCA outputs".
