i ahve 2 12" boston acoustic G1's with a JL audio 500watt amp with 4G wiring for future upgrades. I ahve the stock desck installed and i had a HI-LOW- covertor installed so i could run my subs and stuff. in my 2006 EX once i hook the subs up it will only pick up certain radio stations. IDK why it is doing this... any thoughts???
