Connecting 4 bass speakers to one amp?

Bass cancellation can occur if the polarity of one cable is reversed? Positive at the amp MUST go to the positive at the speakerS else one speaker will be pushing & the other pulling & the low frequencies get cancelled. You may also hear some strange imaging effects as you walk around the room - a bit like stereo from a mono setup.... check your cables :-)

i have found the specs to your amp. 1. Amplifier connections: Lets make things simple. As we look at the amplifier speaker connections, we will number the outputs 1 2 3 4 from left to right for the top connections and again 5 6 7 8 from left to right for the bottom connections. 1 should be connected to a positive (RED) (+) on sub woofer A on voice coil (a) 4 should be connected to a negative (BLACK) (-) on sub woofer A on voice coil (b) Now using a small piece of cable, connect negative of voice coil (a) to positive of voice coil (b) Follow the same procedure for the other sub woofer using 5 and 8 as 1 and 4 This configuration should make the amp run at 4 OHM BRIDGED x 2. i hope this helps. dreamsystems

Use the left and right to connect the positive and negative to the respective speakers in the right and left. Please make sure of the polarity and so be cautious. next you can connect the sub woofer from the left and right channel as the amp is bridgeable. Use the lead to connect from the R- positve to L negative. test and check the phasing of the speakers, must get good low bass or else you can reverse the sub woofer and check again. If you ae having frint speakers connect accordingly the the other channel. Helpful Good day

only subs should be hooked up to the amplifier the amp is mostly for bass anyways have your 6*9 just hooked up to the cd player itself to where its just for your vocals

HI DUDE .. I JUST GIVE suggestions Boss Car Audio D5504 "Diablo Series" 4-Channel Car Amplifier 2200 Watts ITS REALY GOOD FOR SOUND SYSTEM DUDE

Hello ctr1russo,
While it's not impossible to install a new head unit and speakers and leave the factory amp, it'll be a real bear of an install.
In order to work, the Monsoon amp needs 6v which is provided on the speaker leads. An aftermarket head unit will not provide that. Best to just install a new amp.
You should be able to use the wiring, including the speaker wiring, with no problems.
Check out www.bestkits.com for the appropriate adapters and wiring harness for Monsoon equipped vehicles. Just enter your vehicle info and it should bring up the required adapters and harnesses to make everything work properly.
There are three ways to connect more than one speaker to a single channel: 1) Parallel - both speaker +'s and -'s wired together - load impedance will be halved (2 4-ohm speakers in parallel equal a 2-ohm load). 2) Series - The + of one speaker wired to the - on the other speaker and the remaining + and - going to the channel output - load impedance will be doubled (2 4-ohm speakers wired in series equal an 8-ohm load). 3) Using a crossover - connect the bass speaker (woofer) and the input of a high-pass filter directly to the channel output and the treble (tweeter) speaker to the output side of the filter. In any of these connections, you want to make sure that the load (ohms) your amp "sees" is not less than it is rated for. Most amps will work into a 4-ohm or a 2-ohm load with no problems. Going below 2-ohms is bad, because it will cause the amp to overheat and possible fail. Going above 4-ohms is no problem for the amp, but it won't produce as much power (watts) at the higher impedance and your speakers will not be as loud as they could be.
Hope this helps. If it does, please rate as "FixYa:. Thanks!

You probably need your remote wire re-hooked and make sure the ground wire is good and the remote wire is connected to the right wire(the red wire).

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Amplifier in Protect Mode - Troubleshooting

Let me know if you have any other questions.

If I'm reading the amp manual right, you should be able to connect the amp in 3 channel mode. To do this:

• Connect both left door speakers in parallel to Ch A Left.
• Connect both right door speakers in parallel to Ch A Right.
• Bridge Ch B and connect it to the new 8" sub.
• Set the Ch A LPF/HPF to HPF.
• Set the Ch B LPF/HPF to LPF.

This should allow you to run all 4 door speakers and the sub from the amp. It will also automatically route non-bass to the door speakers and "only bass" to the sub.
