a motorcycles charging system doesnt compare anywhere close to that of a four wheeled vehicle

so any suggestions on an efficient amp thats small in size
and power draw to run four 5.25" polk audio db521's

the four channel alpine? f300? ktp-445?
arc? others?
thanks

id say Arc (or their clone), they use G/H class,are very efficient and very small.

125.2 mini and parallel the a pair on each side, each speaker will receive around 60w and the current draw will not go over 30A.

parallel the pair? wont this change the impedance?
can i do that? obviously yes, but is there a downside?

nope stick with the ARC you won't be disappinted with the power and size.

Yes the load will be 2ohm on the amp, but the 125.2 mini can take it. Also the parallel pair will play at the same level and can't be adjusted, only the L/R will.

How the speakers will be layout?

all i care about is left/right which i would leave centered anyway
i was just likin the price of the alpine ktp-445
a lot less than the arc, and i am trying to do this on a limited budget

buy the right product the first time regardless if you are on a budget. IMHO alpine will be gutless from the specs in comparison. Even the Arc clone would be a better choice then the alpine

yeah i was working on a limited budget too before, trying to find the best buck per watt kinda deal. But i learn the hard way, and spent way more money on different amps trying to get what i wanted. Spend the extra cash on Arc and forget about it.

i guess your right, ive done that before!
so whats the arc clone called?
where can i get it?

lpchouinard
