These two shouldn't have a problem running well together if you bridge it and run at 4ohms you will see about 400 rms to the sub, which is adequate to what it's rated at.

I would say that be careful with the placement of this amp though. I have owned the same version and it runs very hot and can also burn out easier than most.
You shouldn't have a problem as long as the top is free to air, and the bottom is not laying on carpet (Mount it to a piece of MDF or any wood so it has free air underneath)

This is from experience using this exact same amp.

For future purchases, Never buy alpine amps.
At $90 that was a adequate deal though.

As for wiring kit, even though everything @ boss audio sucks, wiring kits are all the same and its on sale.

Thats a cheap kit that fits your purposes.

Enjoy ;D

where are you seeing it will run at 400rms? its a 4ohm svc sub and a 4 channel amplifier that only puts out 120rmsx2@4ohm. so at best it can do 240rms with a ton of distortion that will kill the sub either way.

bridging it down to 2 channels then bridging those into 1 channel again doesn't even sound right. i've never tried a 4 channel on a svc subwoofer but it sounds like a terrible idea from the start.

and how are all wiring kits the same? the problem with cheaper brands is the wire is actually much smaller than they claim and half the time its not even copper but copper coated aluminum or just aluminum.

Yea sorry i just realized it said max in bold under that rating *failfacepalm*.
In that case I would not reccomend using that amp for this equation, because for startes its a 4 ch amp meant for mids/hi's, not subs,
It however is possible, but it will not be seeing very much power considering the amp is only going to put out a max of 300 stable rms wattage, and since i have seen how hot this amp gets this is even more so, a bad idea.

As for wiring,
I have installed probably 20 different setups using cheap-highest grade nasa wire, and i have never had a problem while installing/after install/ or down the line with any of the wiring going bad.

The only problem i ever see with cheaper kits is the fuses sometimes plainly suck.

This is just what i have experienced, so its what i recommend.
