You can find one $75 and under with a ton of power that can drive a 2Ω load (two 4Ω 12″ wired in parallel for example). After adding the sub to the system I’m missing Left to left sound and Right to right sound effect. Unfortunately the amp manual isn’t helpful. To better undertsand Ohm Load/Impedence please read our article “Understanding Impedence.” in the articles section or by clicking HERE ***PLEASE NOTE*** All information on this site is … Then bridge the rear channels to drive the subwoofer. If connected properly the issue should be eliminated. If there’s something I misunderstood or more info you have, just let me know. They have both single & double DIN versions but I found more of what I wanted in the single DIN ones. 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. After many hours of research and frustration, im still unable to find a way to wire my subs up correctly. For example, our XTHUNDER1200.1 amplifier is rated for 1200 watts RMS @ 1 ohm. So don’t worry you should be ok. You’ll need at least one pair of RCA cables, or 4 if using a front & rear fader if the radio has 4 outputs. Regards Neil. I want to bridge two channels to power my 600w rms sub. 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). Does this mean that the amplifier supports 4Ω and 2Ω connection? You can also use multiple resistors like this: 2Ω 25W + 2Ω 25W = equivalent of a 4Ω 50W. Don’t do it! Here’s an example chart to help you know what to expect when measuring speakers. While there are several ways you can go about it, wasting gas, time, and getting stressed out isn’t worth the headache. You can use 2 subwoofers, but the total load will have to be 4 ohms (unless it supports 2 ohms in bridged mode. It’s 4 channel with only speaker line out (no rca). Is it possible or feaseable to add resistors to the woofer, like you suggested for speakers running on a 4ohm minimum load amplifier? Two sets lead over to the amplifier (the ones I mentioned previously). It’s a little bit tough since I can’t hear your truck myself, so I’ll do the best I can. I recommend a model with adjustable level outputs (PAC and Scosche make some very good ones). In the case of a car amplifier that can’t go below 4 ohms per channel, there’s no other way. After playing, decided to go ahead and connect all 4 speakers to zone 1 leaving zone 2 available for either another amp or future move to a 5 channel amp. When you wire the subs as shown in the diagram below, the total impedance will be four ohms. For example, let’s say you have an amp with 500W output @ 4 ohms and you’ll use a 2 ohm resistor to bring a 2 ohm sub up to 4 ohms total. Say I’m using set up #1. However I want to use a DVC 4 ohm woofer. Right channel to front right, rear right. Any suggestions on how to set those?and one more thing sorry. Hey Marty thanks so much for all the great info! Really appreciated. Note: Most standard aftermarket car speakers are 4 ohms each so I’ll use that assumption for my diagram. This is the first and best choice for most modern 4 channel amps. If the meter has an auto-ranging function you should be fine. I’ve put together some really detailed information to help make this as painless (and inexpensive) as possible. switch or RCA Y adapters), then back from the amp to the factory front speaker wiring as I mention in the article (easier doing it at the dash). Love the period look but it’s almost inaudible after 40mph due to the road and wind noise so need more volume. Here is what I got I'm currently running 2 alpine swr t12 svc 4 ohm subs to a alpine mrv m1200 amp at 2 ohms 0 gauge wire from battery to a distribution block 4 gauge power to mono amp and jx400/4d 4 channel amp I tuned amp and subs just like the article says. However, you’ll want to buy the right kind of resistor. awesome Marty, btw I’m in Oz & just clicked link for pioneer on amazon, that item they don’t ship down under :( – but Im sure I can source it locally, or other ones similar, I know this might sound silly sorry as I’m not upto date with the tech side of audio, with the hidden head unit being bluetooth does this still mean the operation is all controlled by iPhone/App or remote that comes with head unit if supplied? Today’s 4 channel (and other) car amplifiers have a minimum speaker load they can handle. So, here are my thoughts: 2. please tell me if i have bought the wrong equipment or if it isss at all possible to make it work. What would be the best combination to get best sound output and “left to left/right to right” sound effect? I’ve got a 70 Mustang, & will be leaving the original radio in its place to keep it all looking original, I’m looking to put a aftermarket sound system in, a freind has a Rockford Fosgate P400-4 punch I can have, I was hoping to run a sub in the trunk & replace to front speakers with decent ones, can this amp be installed & possible adding a bluetooth device while using my iPhone as the head player, this way I’m avoiding installing any head unit, or would I need to buy a different Bluetooth amp, any suggestions or hep in which is best way to go would be greatly appreciated I usually recommend a minimum of 50W RMS/channel for amps driving full-range speakers, and yours will be able to drive 2 speakers per channel with 55W each. If you're only using 1 speaker/sub, you run it in Mono. Sure, and good luck with your installation! – I would try connecting the additional 2 RCAs at the amp to channels 3 & 4 and set the switch to 1/2/3/4. Lorenzo shows you how to wire your speakers to your factory wiring harness, being powered by the head unit's amplifier or an aftermarket Kenwood amplifier. R channel to ch. • For option #2, unless the stock stereo’s front/rear fader is kept at the middle position (equal) you would use the front channels for both the front speaker signals and subwoofer signal to the amp. Connect both cables to the left and right outputs on the amp (a pair of cables to the left and another pair to the right). The Pioneer’s internal circuitry scales down the speaker level signals to line level. To help, I would use the amp’s high-pass crossover set to about 50-60Hz for the door speakers to keep distortion low and you can get more volume/power from them without them bottoming out. I've got 2 x 12" svc 4ohm Pioneer 160W RMS subs running off a cheap 2 x 120W RMS 2 ohm stable amp and a 4 x 75W RMS (2 X 100W) 2 ohm stable amp running the front (6 1/2" splits and back 6" speakers. 2 front speakers and a sub – not both way for your kind and quick reply an issue!
