I just bought a 8" Kicker Comp. with a Kicker ZX100.2 Amp to in stall in my truck. I'm not looking for really loud or hard hitting sound. Just wanting better sound with a little more bass. Do you guys think that this will help?
Yes
Im a firm believer that no matter what you listen to, you need a little bottem end, a good sub always rounds out a system. You wont be disappointed.
will be putting this weekend. if it sounds like i think its going to sound, just might get another 8".
More than likely, youll be trading those 8's for a couple of 10's..... Trust me, It never ends.
thats what i'm afraid of. i used to have 2 12" kicker comps years ago on a 1000 watt amp. my wife made me give them up. 
That sucks, Me and the Wife have an aggreement, I dont complain about her shopping, She doesnt complain about my truck and related accesories.
she tells me that i'm too old for stuff like that. everytime i buy something for my truck, she tells me that i'm putting my truck before my kids.
Your never too old for something you enjoy. I guess im just lucky to have a wife who doesnt mind such things. And with my son, man I wish I had the toys he does... but I guess thats what its all about, I love to see him happy. When Daddy gets a "toy" so does my son. The wifey too btw... I just recent got schooled on Coach purses. 
(P.S. Stay away from the Coach Store....)
i hear ya bud. my 2 boys has alot of toys. my 7 year old whated a 4wheeler, so i bought him one. now, he want even ride it. but wife didn't say anything about that $1000 down the drain. he wants to stay in my shop and play with my toys. whats up with that?
Well I can tell you, at least with me anyway, what daddy does is what my son wants to do. Hes only three, but would rather be with me on a tractor or my old man in the crawfish pond than watching tv. Best of luck convincing your wife that you NEED those new twelves.... 
well, i figured if its my money that i make for my shop welding and selling, i buy what i want to buy.Well Good Luck to you. Remember its easier to beg for forgiveness than to ask for permission.
