I’m thinking about just letting Best Buy do my installation of a 200.1 amp and a 500.1 amp for the sub. I’m also having a TRTP Kicker down firing sub box installed in the cargo area.I have never installed a sub before and know very little. My question is do I need to buy a plug n play harness since I’m not installing everything? Can they do the install without a harness? I want the install done right, but if they can hook both amps up without using a harness then why spend 275$ for a harness?
