Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.

I Have a Sony Xplod 800 watt amp and 2 12 inch Sony Xplod subs


You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

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


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.

MRV - 1507 Question ...


The MRV-1507 is a two channel amplifier, below I've pasted important info from the manual:

Battery Lead (Sold Separately)
Be sure to add a 80 amp fuse as close as possible
to the battery’s positive (+) terminal. This fuse will
protect your vehicle’s electrical system in case of a
short circuit. If you need to extend this lead, the wire
gauge should be AWG8 or larger.
MRV-1507 ... 80A amp fuse

Power Output: RMS Continuous Power (at 12.0V, 20 Hz to 20
kHz)
MRV-1507
Per channel into 4 ohms ......................... 150W, 0.08% THD
Per channel into 2 ohms .......................... 300W, 0.3% THD
Bridged into 4 ohms ................................ 600W, 0.3% THD

You can find a manual for this amp here:

Sub power hadling capacity


Yes. If the rated power is 380W and the Max power is 1000W then it will handle it. Subs fry when clipping occurs. Clipping is when the amplifier is pushed past its capabilities and the output to the sub gets "dirty". The better quality the amp, the safer it will be on your speakers. It is also important to remember that the gain control on the amplifier is NOT a volume control to boot the sound, it is only to match the output from the headunit to the input handling of the amp. Cranking the gain up too much WILL CAUSE CLIPPING.

V12 / xplod issues questions


sounds to me like you have a poor ground, which is causing the amp to overheat. make sure you have as large a gauge wire for the ground as you can and make sure it has a good connection to metal this should solve your problem.
