[10" 200-250RMS subs good for small sealed?]

Could also do the aq sd2.0 if his mind isnt completely set

[voltage drop]

To fix voltage drop is to produce enough current to keep the voltage up.

Adding/upgrading batteries will help keep it above 12 volts but will be still drop.

If you want 14volts with hardly any drop, you need to upgrade alternator, or add another one.

If you don't mind the dropping but can live with it being at battery voltage, upgrade and add a battery.

thanks for the info. but do you think a rockford 1500 could draw that much? and maybe its my meter that is crap?

i had this amp in my dodge at 2ohm and it barely dimmed lights. would changing to 1ohm make that much of a difference?

[voltage drop]

thats horrible i dont drop below 13.8 with stock alt no big 3 just a walmart bat up front and reg bat in trunk. bmw... aq1200d btw. are u sure your readings are right?

i was thinking maybe the stock meter is shit. but it might be just that weak

[voltage drop]

it is wired to 1ohm. it drops to like 9-10v at idle. and drops to 12 when driving city.(atleast what it says on stock voltage meter)

[voltage drop]

i just put my 1500 and 9515 in my fullsize blazer. and i noticed that im gettin terrible voltage drop. what would be the best way to fix this. an alt or a second battery or a stronger front battery.? all help appreciated
