if i have an alpine 9813 which will have alot of mode to choose and i will buy and mb quart rsc 213 which have crossover. is the crossover worth anything if the alpine already have crossover. or should i go with coakcial speaker. will it sound good if i hook it up to the alpine receiver with the crossover. my second question is if i hook the rsc 213 to an amp can i hook another speaker to the alpine at the same time so that equal eigth speaker. if i can hook it up that way should i use coakcial speaker or component to hook it up to the head unit.
Please solver this big question for me....thannnnnnnkkkk..
