Kicker makes great speakers if you are looking for a cheaper route. Their KS series are very nice. I am running a Sony deck ($129.99), 2- Kicker KS 6x9 in the front ($199.99), 2- Kicker 5 1/4 in the back ($80.00), a cheap 300w amp off Craigslist ($40.00), and a Ram single 10" sub box w/ a 10" JL Sub (Craigslist $60.00). The system sounds great!!!! Total cost: $509.98. A good place to buy your speakers and deck online is: www.onlinecarstereo.com
. They have good customer service and great pricing.
