## Questions & Answers

**Q: Is this amplifier for my car door speakers? If so, what watts should my speakers be? I have 2-6.25” and 2-5.25” And what about tweeters?**
A: Great amp. You say u have 6.5 and 5.5 speakers are the 6.5 component? Or you just have a pair os tweeters that will like to add? If your tweeters have a capacitor it won’t change ohm’s and can just be installed with the front or rear speakers. Hope that helps. I’m running (4) 6.5 Rockford fosgate and (2) tweeters

**Q: what size speaker wire can this use 12 gauge or 10?**
A: Either one should be fine.

**Q: Is this amp waterproof ???**
A: No it is not you would need a marine amp polk audio makes the best water proof amps on the planet in all wattages check them out😁

**Q: Can I install the 4 door speakers and 2 tweeters on this amp? Would this amp be able to handle it?**
A: Yes this amp has more than enough power to handle your door speakers .

### ⭐⭐⭐⭐⭐ This amp rocks!
*by G***E on February 8, 2022*

I've been using MTX amp's since 1996. They always put out more than they advertise. I power the front(Mb Quart 6.5in. components) and the rear (Focal 6 X 9) with the Thunder75.4 and an MTX Thunder 280 for the sub. Fantastic sound. Kenwood head unit
