Question about Sony Xplod XM-1652Z Car Audio Amplifier

2 Answers

Sony Xplod 1000 watt car amp quit working.

Hi, I installed a Sony xplod 1000 watt amp, and two Pioneer TS-300R 600 watt 12" subs into my son's car a few months ago. it sounded great for about two months and then it started shutting off when he turned it up, and steadily got worse before totally quitting. we removed the amp and sent it back to Sony repair, and they sent us another amp. I installed it today, and it still does not work. the red LED light is on, and there is power from the battery to the amp. the sterio head unit has a seperate "on off" selection for the subs, and it is switched to "on". any ideas as to what could cause this? I think there is a seperate "hot" that powers up the amp when the head unit is turned on, but don't know if it's a full 12 volts, and was wondering if I can put a jumper wire to see if it works. one more thing, I bypassed the amp and checked the speakers. they do work.

Almost all after market amps use 12v at very very low amperage to trigger the amp on. A temporary jumper from the battery plus terminal on the amp AFTER the battery and ground wires are attached should cause the amp to turn on. I would check to see if you have attached your speaker load correctly ESPECIALLY if you are bridging. Most of the blown amps that come into my shop are due to incorrect bridging loads from the speakers. Note that a 4ohm load bridged across both outputs of an amp will deliver a 2ohm load to each of the channels. When you parallel wire two 4ohm speakers together and then attached them to a bridged amp you will be putting a 1 (one) ohm load to each channel of the amp. Please don't make this mistake. It will fry your amp in about a month. Hope this helps. Good luck.

Amplifier For Powering Sony Xplod xs-l121p5

Pump the brakes!
You need to know the RMS power rating of the sub you are powering.
Dont exceed the RMS power rating of the sub by more than 25%.
If you see a peak power rating on either the sub or the amp, ignor it, means nothing. Always compare RMS ratings.
Example: a Sony 12" Xplod sub, boasting 1200 watts, will only handle, 350 watts RMS, so the amp you choose to power the sub should be 350 watts RMS as well, and should not exceed more than 25% of the RMS power handling (487.5 watts).
Bottom line, know your RMS numbers, not Peak.

Getting my son a sony xplod xm-1652 2 channel what subs would sound good and the things says 1000x2 and 500x2 what is the truth

165 watts x 2 @ 4ohms and 200-230 [email protected] 2 ohms or 400-460 watts bridged into a 4 ohm mono load is what the amp will actually do. A single 12 inch sub or a pair of 10 inch subs or 12s would be great

Sony Xplod

If your still getting a green light, it at least sounds like the amplifier portion may still be funcitonal. Perhaps your inputs are blown. If your comfortable with electronics, pop the cover, and try patching a signal directly to the amplifier stage. and of course check your source.

Will a SONY XPLOD XM1652Z 2 CH 1000 watts hold two 12in subs?

should do easily though you may need to employ the use of a cross over just incase something goes pop and burns you're car out when you park it after you've been hammering the subs.

Can I run 8 speakers and 1 sub through 1 1200watt 2:1 Sony Xplod?

asuming the 8s are 4ohms each; wire two in series and that gives you 8ohms then two more in series then you put those together in parallel and it gives you a 4ohm load. repeat with other four for the other side. you should then be able to bridge the sub


series; posative of one speaker to negative of other speaker and that doubles your ohms

parallel; posative to posative negative to negative and that cuts the ohms in half
