sorry you are mistaken the alpine amp MRV 1507 is a two channel amp and it has tons of power 900rms at 4ohm but you know how to use it coz crossovers on top is difficult to use.I recommend you to first change wire to 0guage and big 3 then see the diff.another thing u should check how you wired your subs the alpine amp would not run on 1ohl or it cuts out at 2ohms.adding battery would never help in long run coz ur alt charges the batt when car running which is 90 ampere by which u r not able to fully charge those batts so useless to put batt.add an alt 200amp and u would be very happy if not then add a battery.look at ebay for alt might be around 150$.one more thing when u buy amp buy only quality brand and always look at efficiency of amp if u are not competing.i hope it helps

no, i disconnect the alpine v12 1507 already, im trying to see, would i need a extra battery when i run my orion hcca d2400 two of them and 2 eclipse sw9122 ti. because thats 3 amps one running my mids, and two sub. my yellow top might not handle it. because i dont want the light to dim or drop in volts when i turn it up.

the v12 i had it hook up months ago and disconnect it.

just wanna know can i use a yellow top in the front and a red top in the back, or do i need to use same battery, when having 2. someone told me its best to use same battery two yellow top or two red top dont mix them up.
