Reviewer: jeff taylor

These are the most durable and best subs i have ever owned and i have owned alot of high quality subs like audiobahn aluminums but with the easy replacement coils is the best feature that has ever come out but what i really wanted to say is that the subs are only 375 watts rms but i have a 1300watt soundstream monoblock 1ohm stable amp and they slam with all 1300watts running to them so they hold plenty of power and before that i had my boston acoustic GT28 running them at 4 ohms and they were 1 of the cleanest subs i have ever heard.

I have 3 G-3 subwoofers in my escalade. I didnt want to remove my third row seat, so my friend Ricardo at SOS electronics in los angeles Cal. suggesed the G-3. I was surprised by the bass I obtained out of them with so little space.I am pushing them with a t-1000 reference amp from Rockford Fosgate and man they sound clean and loud. A lot of people dont believe in boston until they hear my truck and get convinced of how good these subwoofers are. We are working on a el camino and we plan on using boston subwoofers and I will post the results.
