Can I use 8 gauge wire for my mtx rfl600 - MTX RFL600D Car Amp

Mtx 801

if the subs are different models or sizes don't install anything.
use the best subwoofer you have, if you use both you can have cancellation with uneven woofers or damage them. use a large ported box and tune it close to the music you listen to.
use a minimum of 4 gauge copper or cca wire. anything smaller and you risk burning the wire, the brand doesn't matter. use 14 gauge or larger for speaker wire and setup your impedance of your subwoofers in the pattern that will give you more power.

This amp takes 0 gauge inputs. So I suggest you beef up your power wiring if you haven't. If your running this at 1ohm. You need a second battery, or a H/O alternator. This amp draws some current and if you can't feed it, it will overheat.

I have a Rockford fosgate punch 1000.1bd in a sealed enclosure about 1.5 cubic feet each. I have 0 gauge wire for the amp and running it at 1 ohms. My surroundings are dry rotten on both subs. Need new surrounds

You need to get another amp for your sub. I would say if you want good quality go for MTX because I have had amps from MTX and never had a problem. what you need to know is look at the fuses on the amp if there are 3 of the 25 amp fuses on there then it should push out about 750 watts but on MTX they under clock the amp so it will push about 800 at 14.4 volts for that you will need a 4 gauge wiring kit with a 60 amp fuse in the fuse link. As far as your other amp hook up the speakers and tweeters to that but be sure to tune in down and you would need a 8 gauge wiring kit. I hope this helps you.

it all depends on what kind of box the mtx subs are in as far as wiring the subs. The best way would be take the speaker wire from both sub boxes and run the positive into the right positive then the negative into the left negative. and run 8 gauge wiring kit to the amp because 10 might be to small and 4 is to big 8 gauge is perfect for this amp.

Hi i use rockford fosgate amps they are the best you can get a great punch amp on ebay that will hit them great try seller> fingerz022 on ebay i bought mine from him and its hitting my 15"s nice...

first of all you should check the minimal impedance your amp handles , if is class d it should handle between 1-2 ohms total impedance in a mono conection , meaning whatever quantity of subs you have hooked to your amplifier,their total impedance should the minimum the amp handles that way all the power from your amplifier will be used.

Since the distance is short, you can go with 14 gauge wire but 12 is pretty much the best you can use...

Hi jimmyjames,

 

How do you have the wires hooked from the sony reciever to the inputs on the mtx? 

 Sounds like your Remote wire is way too big. it should be 14 guage.  It only sends a low voltage low amp signal.

 

Another thing that could be messing up the sounds is the routing of the wires.  you should have the power supply wires separate from the Audiop signal wiring.  Power should run down the Driver side and Audio down the passenger side.

 

When you answer I may be able to tell you more.
