Hey people. First post here and I thought it'd be best to ask audiophiles what they think or can offer. I have an 06 Charger SRT8 with 6disknav system and about 8 kicker speakers and one sub in the trunk which are all factory. I'm looking to buy an amp that can run an additional sub on the other side of the trunk and perhaps add a couple additional speakers somewhere in the car but I want to keep my head unit. I'm also a noob at car audio but know it can be expensive. Can anyone offer me some advice for these components and if anyone is selling these components, I'd be interested in hearing from you. I don't want to run an extra battery or anything though lol. I'm looking for some more bass and the ability to run things louder but with two little kids both under 3 1/2 and a wife who gets annoyed by it, I'd like the extra ooomph when I'm out and about on my own haha. Thanks in advance.
