i have some kicker 8'' midbass to put in the door (08 must.) but it a signle coil and the factory is dual coil, can i tie the speaker negative wire together and the postive wire together, i'm running the factory amp

 

I wouldn't recomend it. You really need a good amp to push anything bigger then an 8 and the factory amps are made to work with the factory speakers.

 

aftermarket amp

 

Was this a needed post I think an aftermarket amp was covered when TTOCS said the samething.

 

just confirming what he said
