MA 5 channel or SoundStream

[jstan8806]

I new to the forum so I apologize if this has been addressed before but I couldn't find it. I'm in need of a 5 channel amp with a sub channel rms rating of what these are putting out 750-800. Just to specify I'm talking about the Massive Audio Massive Audio NX5 Nano Block Series 5-Channel Car Amplifier and the SoundStream TA5.1250 Soundstream TA5 1250 5 Channel 1 250 Watt Amplifier | eBay I Would need all the sub power so it would be wired to 1 ohm, do you guys believe both will perform well at 1 ohm. Also is one gonna be cleaner than the other. thanks in advance

For the heat of Arizona I definitely do not recommend running the NX5 at 1 ohm on the subwoofer channel. This amplifier has thermal issues because of the heat sink, which you can see does not have an excess of surface area or mass to quickly rid the chassis of heat. I'm much more comfortable recommending the JBL GTO-5EZ, although it's not rated for 1 ohm operation. Do you have your subwoofer purchased already?

I haven't bought subs yet nor am I set on running a 5 ch amp. Its just that my truck is brand new and I am really hesitant to mess with I want to keep it clean, efficient, and neat. So this system will be for a 2013 f 150 supercab.(extended cab) From all my own research it seems that the fox acoustics dual 10" sealed box is gonna be my best bet as far as mass produced enclosures go. the fox box has a mounting depth of 6" and is sealed with a volume of 0.65 cuft3. I am interested in these amps because they have some of the highest output for the sub channel from my research, I want around 800watts RMS for my subs. How close should my subs be to their recommended enclosure volume because so far I have crossed off all subs whos recommended enclosure volumes who do not match up with the fox box specs. Is there a rule of thumb to go by lets say if your sealed box is smaller than recommended you need a more powerful amp than if the volume of the box was bigger.

Ideally I would be able to run 2-12"s in a ported boxas I listen to rap/hip hop 98% of the time, but I just dont have the room. Under my backseat i have a height of 6-7" in the front and it tapers down to like 4" in the back. I have about 14" from the start of the back seat to the back of the cab, and about 36"+ wide, and Sorry if I got a little off topic and thanks to all who reply. I tried to paste a link to the page for that fox box for reference but I'm at work and the computer wont let me.

The CT Sounds 60.4-500.1 would work well for your application.

As for the subs, look for a high EBP sub. You can calculate EBP by dividing Fs by Qes. Subs with an EBP above 50 will work best in smaller enclosures and low EBP subs will need large enclosures.

When you run a sub in too little volume, low end extension is diminished and adding power will only make it hit louder, not lower.

Fox Acoustics comes highly recommended, and while I have not had experience with their enclosures they do look very well made. For a 2009+ Supercrew with 2 10" subwoofers this is the enclosure you should have: F-150 SUPERCREW 2-10" VENTED 2009-UP

Is this what you were looking at?
