techronics.com, sonicelectronix.com, woofersetc.com are good sites to buy from. Don't buy from onlinecarstereo.com or dealercostcaraudio.com. Both of them will f*ck with you. I've read a ton of bad reviews about dealercostcaraudio to not even attempt to do business with them and I recently got screwed by onlinecarstereo. I heard from a few others after the fact that onlinecarstereo isn't the best to order from anyways. I got my issue straightened out but it took them a couple of weeks to do so. They shouldn't have f*cked up in the first place. Hope that helps you out in your audio endeavor.
