Review: Get loud for the low - Got the mids talking pretty loud and at a amazing price couldnt beat it.
Review: I went to a professional and he sent me away, i didn't need his install it was easy to do DIY - I am no expert of installing Car Audio, but I bought a Nice little car android with touch screen and the installation was not that clear, so It wasn't just a plug and play in by Fiat Abarth 500 with the beats Subwoofer, however I managed to connect my speakers direct without the beats amplifier and the sound was crap, however I got on this amplifier and bought it with the expectants to be able to improve the sound and use my Sub woofer. And it worked perfect. i used the high in not the phono plugs and it just worked great. Yes I did see some one saying on the reviews that it does get hot, but as long as you give some some ventilation it is OK. It is running all my 4 speakers and my OEM factory subwoofer. Instructions simple to follow. All I would add is if you detail what is in the box, you would have saved me $20 from not buying the two 4 pin plugs for the high input. These do come in the package.

## Questions & Answers

**Q: How many ohms per channel?**
A: 2 ohms per channel is ok. I have had a few set ups running 2 ohms per channel. No issues. If you bridge the sub, it will only be stable at 4 ohm. It may do 2 ohms bridged for a week before it blows up. It will go into protect mode if you try this.

**Q: Will theses power 4 door speakers? Not sure how all this works. Just heard that door speakers sound better with an amp?**
A: I have used this amp in many different configurations. 4 channels = 4 outputs. It is 2 ohm stable meaning you could hook up 2 4 ohm door speakers per channel if you wanted to. I have used this amp as a mids and highs amp using the crossovers in the amp and it was great paired with a 1000W mono sub amp. For that set up I had 2 6x9s and a set of component speakers. I have also done a mustang, integra and silverado for guys on a budget with this amp. mids and highs on channel 1 and 2 6.5 3ways and 6x9s. and then 2 DVC subs on channel 3&4 using the built in crossover and bass boost.  Was it better than my Hifonics 2 amp set up or my JL audio set up? Absolutely not, but if you want  a good sound you can enjoy on a budget, this is a decent amp. Use 2 gauge power wires so you don't overheat your amp.

**Q: Install kit? Does this come with one?**
A: No , I had to purchase kit separate

**Q: Will this be ok for highs/mids in door and two fosgate 10s in rear**
A: This is good for speakers, but not powerful enough to properly run subs as well. This amp generally puts out around 350-400 watts, which is good for quality speakers. For Fosgates, I'd jump up to a name brand amp, or go with a cheap 2000+ watt amp.  I'm running 2x 6.5 mids, 2x 6x9 coax, 4x tweets, and a 3.5 mono high on this amp, and its run them well.
