Hello all. have any of you ever used the alpine power pack(KTP-445)?
will it bring up my 6.5" type r speakers to or close to full potential?

does anyone have one to sell?

 

They're a pretty decent unit. I've used them in bikes and automotive. It will liven up your R's but not even close to full potential. Really should be used with your deck hi pass and in some cases I've ran a fused constant directly from the battery.
