Dry cell batteries are better than wet cell batteries because the latter could spill battery acid in your car if they leak. Most electronic components such as amplifiers, active crossovers and equalizers need about 125mA to turn on. All amplifiers in the system will need a 12 volt signal that let’s them know when to turn on. now i have another 400 watt dual amp that i wanna hook up for some treble speakers. Your voltage should not drop below 12 volts, as that’s an indication of a big power problem. But if you upgrade to more powerful amps and subs, say 3000w, that 8 gauge will burn and melt in no time at all. how to hook up 3 amps. Connect 12-Gauge Speaker Wire from the Negative (-) Speaker Output on the Master amp to the Negative (-) Speaker Output on the Slave Amplifier. When using one large wire for multiple amplifiers you'll need a way to split the power wire into smaller wires for each component. 4. Get 40Hz test tone for subwoofer amplifier, or 1kHz for full-range amplifier. Username: Vernmangk Post Number: 2 Registered: Mar-06: Posted on Wednesday, March 08, 2006 - 01:26 GMT . even with one or two batteries, caps, or even two alternators, you may not produce the amps/volts that your cars original electric system + sound system require to keep it running and major damage can occur to your original electrical equipment because of lack of power. 1 decade ago is there a way to hook up 2 amps in a car? Be warned: many capacitors are nothing more than expensive voltage meters. First, it's usually cheaper than two wires in terms of material and labor costs. Sub-bass frequencies would be sent to the subwoofer amplifier and high pass signals would be passed to the other amplifiers. 4 gauge versus 2 gauge) is negligible compared to the cost of having to run a second or larger wire in the future. Aftermarket head units provide this but it is recommended that you do not connect more than 1-2 components directly to it. Topics range from basic system installation (head units, amplifiers, speakers, etc.) For negative grounded motor vehicle, join the Positive (Red) battery charger clip to the Positive (POS, P, +) clip position. The main factors that you need to consider when you wire in two or more amps are how you will deal with the power cable, grounding each amp, and whether or not the remote turn-on signal from your head unit is strong enough to split between multiple amps. This assumes your amplifiers already have built in fuses that are designed to protect them. We use cookies to make wikiHow great. If you’ve already installed a power wire for an existing amplifier you may choose to simply install another wire for additional amplifiers. remember i want one to be treble and 1 for bass seperatley .... please help But the more subs an amp is placed on, the less power it can give to each individual sub. If you choose to run your ground wires to one point you can also use a distribution block. I would run one wire for several other reasons as well. Connect the … Whichever you choose, you'll need to set up your crossover so that the mid-frequency signal is being sent to the woofers, but the low-frequency signal is not. This is the part EVERYONE gets wrong. Then, hook your ground wire to the ground hook up on your amp. These are sometimes filtered which has the benefits of an active crossover without the extra equipment or installation expense. If they barely flicker, then your power is manageable, but if they almost go dark with each bass note, then it's time for more power. I used a Radio Shack project box and some barrier strips to try and make it clean looking, without having wires all over the place. Im currently running three amps now. Rich woman looking for older man & younger woman. Connect the batteries in the car with a large ground wire and ground it in metal. Otherwise, if one amp fails, you may find yourself overwhelmed and needlessly tearing out wires. I want to know is do I need a distribution block to hook both amps up and can I install the 4 channel up now so once I order the door speakers I can hook them up and not have to worry about installing the amp to. That same amp can power four 4ohm subs and so forth. then for the ground, get the same distro block as the power and ground it to one point. then you can use an electronic crossover to split and filter the signal going to each amplifier. Fix the problem by running the power wire to the left of the driver side seat and placing the amp and RCA's under the passenger seat. If you have a feeling that you may go bigger in the future, chose bigger wire. I also have the amp kit for both amps kicker ck4 and rockford rfki. You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra planning. Most of these are less than 1 amp and that is just not enough. I want to know is do I need a distribution block to hook both amps up and can I install the 4 channel up now so once I order the door speakers I can hook them up and not have to worry about installing the amp to. If you really can’t stand to see another ad again, then please consider supporting our work with a contribution to wikiHow. I'm laid back and get along with everyone. Today’s 4 channel amps offer newer technology, better sound, and more compact size than in the old days.

If you're looking to optimize your current car audio system, or even replace your old system for something with a little more grunt, then don't pay someone else to do it. I also have the amp kit for both amps kicker ck4 and rockford rfki. you would need a distro block with an input for 0 awg and and outout for three 4 awg wires. The relay will then connect the 12 volt signal to the amplifiers and other components. one amp is 600 watt sony and the other is … If your using an independant PSU, you might want to remove unnecessary wires. The drawback is that the signal voltage is also split so that each component is now getting a smaller low level signal which may increase the noise in the system. If your amp does not have a good protect system, it could easily blow because of a silly mistake. So I built a relay. The Car Audio Help DVD catalog includes five different videos covering many areas of car audio installation and custom fabrication. A good 220-amp alternator can really make a difference in sound quality and bass. Now that you have your power and ground wires connected you'll need to give your amplifiers a music signal (usually the RCA cables run from the head unit). Will this cause problems with bleeding or any other issues? This article has been viewed 232,477 times. References. The ideal voltage for a car audio system varies. Step 3.

If you want to crank up the volume for parties and plan on using a powerful amplifier, then 5 amps likely won't be enough either. Once you have your positive terminal disconnected from the battery post, you will then connect one end of the red 14-gauge wire to the positive battery post. Just make sure the subs don’t combine to read at 0.5 ohm (a dangerous level for an amp, unless it specifies that it can run at that low ohm level) and all your wires are properly connected and wired. Just make sure that the sub's peak power is rated above 1000w. They are for very minor power problems and simply add a more sophisticated look to an audio system. This prevents your head unit from trying to deliver too much current which can burn out the turn on circuitry in the head unit.
