1. I ordered the Us amps merlin md1, and it says on their site it has 4 gauge awg terminals, but i also ordered the 1/0 gauge from knu, so my question is will it still fit/work? Or can you use any size wire for any amp? 2. Also, can someone link me to where you can buy the steve meade custom woofer from AA, or tell me if it's any good? 3. LASTLY lol: would you recommend a single fi bl 12 or 15 for mainly rap and hip hop? Thanks.
