4 channel, cheap, and suggested by a friend. Small enough to fit in the ice chest radio I am building.

Can I add a sub remote to this amp? & do you think it will perform well with "MTX Terminator 212 Dual Sub (TNE212D)
1200W Max Power, 800W Peak Power, 400W RMS Dual 12" Terminator Series Loaded Subwoofer Bass Enclosure"?

Best Answer: Hi,

-Can I add a sub remote to this amp?

Yes, but not an OEM one. It obviously doesn't have input for Power Acoustik remote, so you would need to get a Universal Bass Knob, like the NVX XBRC. It'll work the same way, and is a very common addition.

-do you think it will perform well with MTX TNE212D

We assume you are asking if the AMP will perform well (not the remote). To be fair, we suggest an amplifier that is specifically meant for subwoofers, not a full-range amplifier intended for door speakers. Nevertheless, the figures do fall within that which the amplifier calls for, albeit barely. Still, we would suggest a strong, better equipped amplifier. Give our sales team a call if you need further assistance.

I have a 1988 Ford Ranger that I am restoring, I was fortunate to get (4) Q-power 10" woofers in an enclosure that fits comfortable to my liking and it bangs just needing the correct amps to push these subs. I am thinking about purchasing (2) of these amps just for the low end and maybe (2) Power Acoustik RZ4-2000D for all of the Coaxials and additional tweeters.

What are your thoughts?

Best Answer: Hello,

We can't speak on the subwoofer vs amplifiers, because we don't know what subwoofers you are referring to, as you've only provided a description. We would need a proper model number to provide an accurate answer. As for the Speakers/Tweeters vs Amplifier, four speakers on one amplifier and four tweeters on one amplifier will work well. The system would have to be fine tuned, consult an installer for that, and would require a steady steady from the source. The figures provided by this manufacture can be a bit ambitious and often only reached at very high voltage level, but this works in your favor, as long as the system is properly tuned.

i have (4) 6.5" jbl gto 628 on my doors and on my rear deck i installed (2) 6x9 jbl p963. i have a precision power black ice ba1000.4 running all speakers. the door speakers are on ch 1/2 and the 6x9s are briged on ch 3/4 and obviously it handles until the amp gets hot then goes into protect mode. i am thinking about getting this amp. my question with this amp is will it put the amp in protect mode when i turn up the volume. i am also running a l.o.c. from my factory radio?

Best Answer: Hello Ricky,

Both Power Acoustik and Precision Power are fairly entry level manufactures. In fact, they are essentially the same brand. However, you may want to give each Rear Speaker its own Channel. Bridging the rear channels is not necessary, and is likely stressing the amplifier, causing it to overheat.
