    hi there. just wondering if someone can help me out.

    i have an alpine mrpm500 amp and want to have a gain control on it but it doesn't come with one. i dont think it has the input (like phone jack) for it so i assume i have to buy rca type and that will work on that amp? will there be room on the amp for that to hook up to even if i need to use an inline converter since i am leaving my factory deck installed? also i have a factory sub and amp in my car but want to add aftermarket amp and sub so should i be relaying into the factory amp/sub and using those hook ups or leave that as is and do totally separate hookup?

    the amp is 2ohm and 4ohm. i have two subs (solobaric l3 and l5. one is 2ohm (with kicker box thats ported) and the l5 (higher version) but is 4ohm and comes with a qlogic box (sealed). what do you recomend would be better? i only want to use one box/sub. i would like deeper/louder bass. thanks in advance.

    According to this, it does have gain control..... http://support.alpine-usa.com/products/documents/OM_MRP-M500.PDF
    Leave the factory sub amp in place but disconnect it, you may be able to use the inputs for the new amp but I wouldn't use the factory output or power(unless the power/ground is up to par with the new amp)

    Now for the second part of your question, simply put, the 2ohm ported is what you want if you decide to go that route.
