I have a Audiobahn a2300hcx, Even though people doubt this amp and says that it blows, it hasnt for me and it does put out 2400 and more if you give it the right voltage which is 14.4 and my system runs at a 14.3. I have 2 optima yellow top batterys to aid in the power and it helps alot but my alts going out and im bout to upgrade to a rewound higher amp alternator. My lights dont dim at all but its getting there once in a while if I drive around a long time and when I have my system up. Im about to get some components up front (I have a set of polk momos thats been sitting here for 6 months because im too lazy to make kicks). Also im about to get another 15" woofer and im aiming towards the hifonics colossus amp next.
