Awesome amp for the price

You will not find a more powerful amp any where else for 120 bucks. This amp is perfect for anyone seeking power on a budget. And its strappable. What more could you want?

Audio Tech In Fresno Car Audio Installer

We sell these amps in our store that i work at and i have to say, im really surpised what power comes out of this amp, it may not be true power but to get the most of it does require a good cap or extra battery, 0gauge power wire with the big 3 aswell. 0 to 4 gauge splitter for the 4guage amp inputs. a good stereo like pioneer or a simple jvc headunit. and a fan to cool it down since it doesnt have a cooling system so to keep it from getting hot. and some good subs like kicker or re audio. it would sound awesome. from Fresno CA, this is my review and i reccomend it for this price.

Alright but the usual issue.

This amp has a great price but I have noticed in the 6 months that I have had this as usual BOSS once again overrated this amp. 2100 RMS you say? It hits less hard than a 900 RMS kicker. It's decent but you can get better. Doesn't over heat and lasts.
I wouldn't recomend it since it is overrated. Spend the bit extra and get a quality amp.

Alright

I was hesitant to purchase this product due to the same reason as the prior review. Boss tends to overate their wattage and that's what they did. This is pushing out less than my friends 1500 Kicker amp. Looks decent and doesn't over heat often. Decent but not the best.

I recommend anybody to buy this amp. I wasn't a fan of Boss but I must say I love this amp. I have a Grand Marquis and this amp has those 2 Kicker Comp CVR's dancing all in the trunk

This amp is amazing. Just make sure that when you ground it to your vehicle that the ground is solid. Have no other problems. Keeps the bass going and no shorting.
