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.

I hooked my Hifonics BXi 1610 Brutus series amplifier up to my 2 12" Kicker Solo Baric L7 subs. Everything turns on on the amp but its barely pushing my subs. Ive tried tuning it and it still doesn't push...


wire the subs if thair dual 4 ohm . in parallel. red to red and black to black. giving it a 2ohm load. do the other sub the same. and conect it on the amp . turn your gain about 12oclock and db level less than 12oclock and your frequnecy around 80-100. and that should work

How should i arrange the wiring on my xm-zr1852 xplod amplifier to get the best performance out of my 12'' audiobahn subwoofers?


it depends on the impedance of the subs-if your subs are dual 4 ohm coils then you can parallel the coils which will give you 2 ohms per sub- you could get max performance from your amp by just wiring the 2 ohm speaker load to each channel of the amp which will hit them with about 200 watts rms each. another way to do it is to wire the coils in series which will make each sub an 8 ohm load and then parallel them together and that will show a 4 ohm load -which you can use to run the amp safely in bridged mode. This will give you exactly the same amount of power to your subs as in 2 ohm stereo will. so with your amp being 2 ohm stable in stereo or 4 ohm stable in bridged mode- those are the numbers you want to hit for maximum"safe" operation

I have 1500 kicker amp and 2 15L7 4oh want to hook up


you can't get full power out of it because those subs can be wired series/parrallel to a 1 ohm load or just series to a 4 ohm load and you don't want to put a 1 ohm load on this amp... you need dual 2 ohm subs for this amp... I have the same setup but with dual 2 ohm subs and it is rediculous... you need to buy different subs that are dual 2 ohm or buy an amp that is stable at 1 ohm... you will only get 750 rms out of a kicker 1500.1 at 4 ohms so u will do more harm than good to your subs.

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.

Installing two amps


No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)

Building Competition stereo's is a big hobby of mine.

Sub Wiring


Hello jtkpay,

Rockford-Fosgate claims their latest V-power 1500bd is stable to 1 ohm, and I would think that your Oldschool would also be. The 2 wiring options for 3 subs with 2 ohm dvc would give you a 1.34 ohm load and a 3 ohm load. The 1.34 ohm option would mean more watts to the subs, but the amp will run hotter. The diagrams look like this:

Using just 2 of the Kickers, you can wire 3 different ways, with final impedances of 0.5 ohms, 2 ohms, or 8 ohms. You do not want the 0.5 ohm load. It's bad for the amp. You don't want the 8 ohm load. It doesn't allow the amp to produce as much power. So that leaves only the 2 ohm, with coils in series and subs in parallel. It looks like this:

Hope this helps. If it does, please rate as "FixYa".

Good price


Hello smoot_dog,

Well, you did not specify whether you have the 2 ohm or the 4 ohm versions of the L7 and that will impact your choice of amps. But with 8 voice coils and 4 subs to work with, you certainly have lots or potential configurations.

If your subs are the 4-ohm version, I would recommend the Alpine MRP-M1000. Currently it is on sale at www.crutchfield.com for $347.00. With this amp you'd wire the voice coils in parallel (2 ohms), wire each of the 2 pair of subs in series (4 ohms), and the resulting pairs parallel to the amp for a final load of 2 ohms.

If your subs are the 2-ohm version, I would recommend the Rockford-Fosgate Punch P1000-1bd which is stable at 1 ohm. Crutchfield sells it for $349.99. With the Punch and 2-ohm voice coils, you'd series the voice coils (4 ohms), parallel each pair of subs (2 ohms), and then parallel the resulting pairs to the amp for a final load of 1 ohm.

Either of these amps will provide an honest 250 watts RMS to each L7. They'll not only rock your vehicle, they'll rock the pavement.

Sony xplod 500w 4/3 channel


If the speaker is a 4 ohm DVC (two 4 ohm coils), you can't wire it to get a single 4 ohm load. Try connecting one coil to each of the two rear channels. It may not be as loud but the amp should operate without going into protection.

If the two 4 ohm coils are in parallel, the amp is driving a 2 ohm mono load. That's probably why it's shutting down.

Pioneer prsx720 wiring question


If the subs are dual 4 ohm voice coils, you could hook the DVC's of each sub in parallel ("+"'s together, "-"'s together) making each sub essentially 2 ohms. Then connect one sub to each channel of the amps. This will put about 200W on each sub.
