Can I do this the cheap way? (Powering a second amp)

[Punk In Drublic 10+ year member]

and OP ground your amps the same way

By this you mean make another y-split and run a ground wire from the new amp to under the drivers seat and ground it with the sub amp, right?

Thanks a ton for all your help guys, I don't know what I'd do without this forum. Probably set my car on fire. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
