so i recently got the alpine 9874 for christmas, but it wasnt the HU i was looking at because I was looking for the usb feature in my new HU. Now that alpine is releasing a whole new set of HUs, i was looking to get the cda-105 since they have the features i want. Since im going to be running everything i have on a stock alt, i was wondering if i should get the jl 300/4 or should i just get the new headunit power pack that alpine is releasing for 2006+ models that will give me 45 watts rms each channel. Do you think the 45 watts rms would be able to keep up with a w7? or should i just get the amp? its also like a difference of 250 between the power pack and the amp..
