i love my factory radio because it doesnt skip like aftermarkets... now i want to upgrade the speakers because they dont sound that good... is like the sounds gets bad the more volume i put... any ideas wich ones will be good but not that expensive? also does any one have the harness information? i need this to install the amp and sub.... also can someone tell me what gauge should i use on a 1600 watts amp and 2, 800 watts speakers? sorry for the many questions, is just that i had a toyota matrix and i used smaller wires and now i want to do the right job... thanks
