I have a battery in the back at the amps. I would like to use my dmm to check the grounds. To clarify, do I need to disconnect the battery before I check the resistance?

no you should actually measure the voltage drop across your system while it is under load to test for a good ground location.

in my 98 Eclipse i just used the factory bolt right under the trunk floor on the left side, i used a 4awg battery terminal and sanded the paint off the trunk floor and bolted the ****er down. i only used 3' of 4awg wire for ground and 17' for the positive, kept the cost down. but Eclipse Spyders are the WORST cars to get loud because theyre soft-tops.. but it works i guess. the MOFO hits pretty decently
