Question about Sony Xplod XM-1652Z Car Audio Amplifier

1 Answer

Kicker l7 dvc 2 ohm wired to sony xplod xm1652z amplifier isnt pushing the sub

I wired the sub so it gets a load of 4 ohms so i could get the most wattage out of the amplifier but it still doesnt sound good, should i rewire the subwoofer so the impedance is different?

It is not the way how get most wattage from your amp. If it is rated to drive a 4-ohm load then it should be ok for a 4-ohm load. If it is rated for a 2-ohm load, then you should not be loading less than that impedance. I recommend a 4-ohm load.
Take note: it is the sound quality from the source that makes up all the total quality of your audio system. If you are overdriving the amps it will give distortion too.
There are many factors to consider when it comes to quality of a car sound system- speaker enclosure design, choice of speaker or driver, equalization, etc...
One more thing, try to get at least no voltage drops if you are wiring the subwoofer amp away from the car's battery.
hope this helps.

How do i wire alpine swr1243d subwoofer


There are a couple different ways you can wire up this speaker as it is a DVC speaker. Duel Voice coil, it has two + post and two - post. A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you'll get the most output from your amp.
Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance.
You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you're wiring two DVC subs to a 4-channel amplifier - one voice coil per channel
Depending on what you are hooking it up to i.e. a mono amp or a bridged four channel amp. I can tell you post to wire exactly if I know how you want to hook it up and what ur hooking it up to.

I have a sound stream xta 600.2 what would be the best 12" subs to with it


match your total rms output at the resistance you will be running the amp at to the subs.
example:
if your amp puts out 300w RMS@ 4ohms, then it will produce 600w RMS@ 2ohms. half the resistance, double the power.
So now that you know your available power, you should get speakers that will be used to the fullest at that given resistance.
example:
If you have two 4 ohm subs that have a power handling of 300 watts, Then you can wire them in parallel ( + to + and - to -) to get a 2 ohm load (which will be 300w per sub with the above amp) or in series (+ to - to + to -) to get an 8 ohm load. (300w amp @ 4ohms = 150w amp @8ohms = 75 per sub).

Keep in mind: choose the speakers to fit the amp, not the amp to fit the speakers. If the amp has more power than the speakers can handle, you will blow them. and ALWAYS USE RMS WATTAGES.

Amp not working blue light is on?


You more than likely have subwoofer(s) wired too low for the amp. It's only stable down to 2 Ohms. You should rewire the sub(s) so that the amp will "see" a 4 or 2 Ohm load.

My kenwood kac 9103d just crapped out on me and i am looking to buy a new amp but when i bought my sub the guy specifically wanted to know what type of amp i had to match it to the sub. so now do i have to...


More specifically, the amp must support the resistance of the sub, or subs. If your amp is 2-ohm stable, it can run a sub, or subs wired for a 2-ohm load. Also, whatever the recommended maximum wattage is for the subwoofer, try not to exceed this much, if at all, with the amplifiers wattage.

How do i wire a mtx 251d at a 2 ohm load


To wire up a 2 ohm load depends on the subs. You will either need 1 sub rated at 2 ohms or 2 subs at 4 ohms wired in parallel. This website will help.
http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=41#results
You can also use 1 dual voice coil sub rated at 4 ohms wiring the same way you would the 2subs at 4 ohms. Good Luck

Wiring for 2 subs for max performance


This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.

2 12" dvc subs 2 ohm stable amp


+ on amp output to + on speaker #1 to + on speaker #2. - on amp output to - on speaker #1 to - on speaker #2. This is a parallel circuit....4 ohms in parallel with 4 ohms = 2 ohms. IF it were wired in series....would represent 8 ohm load.

How do i wire two kicker l7 dual 2 ohm subs to play on a mtx 7801 class d amplifier


Hello moore_broder,

Your MTX 7801 is stable at 1 ohm, but you cannot wire a pair of DVC 2 ohm subs to that impedance. They can only be wired to 1/2 ohm which is too low or to 2 ohms.

Series the voice coils and parallel the subs. On each sub, jumper Black to Red/White Dot, then run both red's (positive) and both black/white dot's (negative) to your amp terminals.

The diagram is here.

Hope this helps.

How do you hook up 2 12" L7's to a kicker 1200.1 amp?


You have a 2 ohm stable amp, and dual voice coil subs.. The L7's come in both Dual 4 ohm, and Dual 2 ohm, so you have to know what impedance your coils are prior to wiring. HERE is a nifty little guide that will show you how to wire your subs. DO NOT WIRE THE SUBS LOWER THAN 2 OHMS ON YOUR AMPLIFIER!

Need to wire two dvc 15 in kicer l7 to 1 ohm


Hello goldy6569,

To wire the L72's at 1ohm, simply connect both +'s and -"s on each sub together. Then connect to your amp terminals.

With 2ohm DVC's, you can have either a 1ohm load or a 4ohm load. The diagrams are here (I know it's the website of a Kicker competitor, but their "wiring wizard" is simply the best).

Hope this helps.
