[QUOTE="DDlover, post: 8685149, member: 678097"] Hey guys. I need some advice on my built. I currently have 4 × Dd815 D2 subs and 2 x DD m4b 5000rms monos. I have wired the two subs at 0.5 ohms so im basically running 2 subs per amp. I have a upgraded alternator of which im not sure what the amperage is and i have 4 kinetics blu1800 at the back and 1 blu2400 in front. I have basically gain matched the two amps but im not happy with the performance. The voltage drop is alot. I also would like to know if it would be better to swop the negatives subwoofer wires on the amps. ( one subs positive with the other ones negative ) i have double 0 gauge runs from the alternator to battery bank at the back and double from there to the amps. I have multiple grounds although i havent checked the resistance. I have been played a few demos and when i connected my charged it went up to 100% in a few min. I have a nocco smart charger.Any advice and comments would be appreciated. Where i am there isnt alot of help when it comes to car audio. Thanx [/QUOTE]
