i just bought my pioneer 7500mp off of ebay it was factory sealed and every thing, well i hooked it up to my new rockford fosgate compnets and my rear pioneer 4-ways and the front driver side blew and the rear passenger side blew. What do i do? we hooked up another speaker and it sounded like s**t what do i need to do? The back speaker is fried , i smelled it and every thing what do it do? That is a lot of money i just spent and it flew down the drain.

 

thats why id never buy from ebay...i dont know what to tellu, contact the seller and see if u can exchange it

 

i bought of e-bay i have pioneer DEH-P740MP same as urs but earlier edition it was brand new have it for a year no problem had it in 2 diff cars too and had systems in both subs and stuff all installed myself... and not one problem... plus the hu can't burn it has a fuse in the back so it should burn out... and maybe u connected the wires wrong and u get ****ty sound.... check all ur wires/wiring and fuses...
