I use to run a 10" MTX Thunder 8500 in my 2004 GMC Savana, then changed over to a 15" Xplod with Xplod amp (Amp is okay but sub was nothing out of this world), and ultimately sold the setup. Now on my car I run a RF Power T115D2 15" sub, and RF T1000BD2 Monoblock Amp. The bass is monstrous and clean. In bass alone I am running a clean 1000RMS wattage and soon getting my 4-channel RF amp for mids & highs.
