Everything else is thoroughly pure HELIX quality without any compromises. Loads of power, excellent measurement data and a whole bunch of features ensure a pristine and crispy sound experience! It is even possible to add an optional volume remote control for the amp channels C and D which is very useful if those outputs are firing a subwoofer. The elegant design not only states right from the beginning the amp's heritage but also allows an easy integration into your car thanks to its compact dimensions. That is sound-tuning at its best!

The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily. Add additional amplifiers with minimal wiring thanks to the Aux output RCA’s and you can even stream Bluetooth directly to this mighty amp just by adding an iSimple ISBT23 Weather Proof BT receiver to your set-up.

However, it is possible to wire a 4 channel amp to 4 speakers and a sub. I’ve put together some really detailed information to help make this as painless (and inexpensive) as possible. Read on to find out how. There are plenty of detailed diagrams to guide you, too. Contents What you need to know first What does the minimum impedance (Ohms) rating mean for an amp. Testing speaker ohms with a multimeter What is “bridging” an amp. Why is this best for driving a subwoofer. What if my amp can’t be bridged. How to connect a 2 ch. To drive 4 speakers and a sub with a single 4-channel amp you’ll have to make a few compromises. Most but not all car amps today can handle speaker loads down to 2 ohms. If yours doesn’t, you’ll need a work-around I’ll show you. You may need a few extra parts. Driving 4 speakers from 2 channels means the speakers are sharing the amp’s power, so you’ll have less power available to each of those. That being said, don’t worry too much. What does the minimum impedance (Ohms) rating mean for an amp. Image showing a typical 4 channel amplifier’s minimum speaker load (Ohms) rating. Most car amps today have a minimum of 2 ohms per channel in standard (stereo) use and 4 ohms minimum when bridged. Never run an amplifier with a speaker load that’s lower than the rating. Your amp will run hot and possibly become damaged. Today’s 4 channel (and other) car amplifiers have a minimum speaker load they can handle. The speaker impedance or “Ohms” rating of a speaker (also called the speaker load) is the resistance to the flow of electrical current that the amplifier sees at the speaker terminals. Amplifiers are designed to handle a minimum speaker load. The rating shown on the amp or in the owner’s manual serves as a warning. If you connect a speaker load below the amp’s minimum rating it can get hot and even become permanently damaged at some point. I’ve seen this happen when people try to “get more power” by incorrectly wiring speakers to an amp. Don’t do it! Burning out your amp’s output stages is not a nice surprise. Minimum speaker loads for wiring a 4 channel amp to 4 speakers and a subwoofer Diagram showing how a car amplifier’s Ohm rating works with speakers. Speakers are usually connected in series or parallel (well, really, most often in parallel) which affects the total resistance an amp will see. That’s important because amps are designed for a certain minimum speaker load (Ohms rating). The real answer, however, is that it depends on your amp’s ratings. Always be sure to check to be sure. Maybe you’ve got an older amp that’s been sitting around unused. If so, you’ll be glad to know there’s a work-around that I’ve come up with that will let you wire your 4 speakers up without damaging your amp. 4 Channel Amp Wiring Examples Here are the speaker wiring and speaker (Ohms) loads possible for nearly all amps you’ll run across. I’ll describe 3 main system setups which I’ll cover in detail. This is the first and best choice for most modern 4 channel amps. Because these kinds of amps can’t handle a 2 ohm load, it’s a bit harder and needs a different approach. Testing speaker ohms with a multimeter Shown: An example of how to measure speaker impedance (Ohms) with a multimeter. It’s a great way to know for 100 sure what kind of speakers you’re dealing with to avoid problems with your 4 channel amp. Car stereo and home speaker speakers are very similar except for the impedance rating they use. A speaker’s impedance value, measured in Ohms, is just the total measurement of electrical resistance the amp will see from the speaker’s voice coil. Partly due to tradition in the electronics world and partly due to various other electrical reasons car stereos are commonly rated at 4 ohms and home stereo speakers around 8 ohms. The good thing is that all you really need to know is roughly what the resistance of a speaker is. If you can measure that you can tell what Ohms rating to go by. How to measure speaker Ohms with a multimeter To measure the Ohms (resistance) of a speaker’s voice coil, hold the meter probes to the speaker terminals, making sure to keep firm contact to bare metal Paint, insulation, dirt, and solder flux can mess up your reading otherwise. For example, we usually have a label on a speaker telling us if it’s 2 ohms, 4 ohms, and so forth. Measuring speaker Ohms with a multimeter Set the multimeter to the Ohms setting. If the meter has an auto-ranging function you should be fine. Otherwise, set it to the lowest setting like the 10 Ohms or 200 Ohms range, etc. With the speaker disconnected, touch the speaker terminals with the meter probes. Be sure to touch bare metal on the terminals and make good contact. Read the measured value. The general range will tell you the Ohms rating of the speaker (Example: 3.6 ohms resistance would mean a 4 ohm speaker) It’s important to be sure you’re not measuring across substances that can interfere with your measurement. Things like the following can cause problems (I have seen this happen many times!): Leftover solder flux or solder coating from manufacturing Heavy oxidation Heavy dirt, dusty, or other contaminants that build up over time Paint or other coatings that don’t conduct electricity If in doubt, you can rub them gently with a bit of sandpaper or even scratch the meter probes against the terminals to make better electrical contact. Note: If a speaker is “blown” or burned out from abuse or physical damage to the voice coil you’ll never get a reading. That’s because for blown speakers the voice coil no longer has a complete electrical path you can measure. Multimeters show an open circuit condition as “infinite” Ohms, which just means there’s no reading to be made. Speakers don’t measure exactly 4 or 8 ohms! Car and home speakers are rated by their general Ohms (impedance) rating. For example, 2, 4, and 8 ohm speakers are never measure exactly with those Ohm measurements. That’s because each speaker’s design is a bit different from the next. The resistance you measure from a speaker is due to the voice coil’s resistance thanks to the long wire it’s made of. Here’s an example chart to help you know what to expect when measuring speakers. Speaker Rating Typical Measurements 2 Ohms 1-1.8 Ohms 4 Ohms 3.2-3.6 Ohms 8 Ohms 6 Ohms or more 16 Ohms 12 Ohms or more As you can see, you won’t measure exactly 4 ohms for a 4 ohm speaker. It will be in the general range and close to its advertised rating, however. What is “bridging” an amp. Shown: Example of a 4-channel amp bridged to 2 channels. Bridged mode (mono mode) is a built-in amplifier feature in which a “push-pull” set up is created: one channel (normally used for the left speaker) produces a signal that’s the opposite of the second channel (normally used for the right speaker). When this happens the result is that you’ll get substantially more power with them working together than you would with one channel alone.
