ok...well im got an 01 land cruiser and the stock system sucks. i need a bit of advice though. i wana get the kenwood ddx6019 for the head unit because its a double din and i like the touchscreen. i just bought 2 sets of these (http://sonicelectronix.com/item_3641.html) and a pair of tweeters. im probly gana buy another set of speakers and then onto the subs. i want these...http://sonicelectronix.com/item_8341.html....4 of them. but i dont know what amp(s) to get. i also need an amp for my door speakers but i only have $1100 to work with and that doesnt include install or wires bc that is free for me... so if you guys have any advice it would be very appreciated. thanks.
