If the car wasn't running wouldn't there be a voltage drop already since most car batteries can't discharge fast enough to meet the instant demand of an amp (mostly just subwoofer amps)? Even if you had a deep-cycle battery (which I don't) batteries take about a second to discharge. What...

I have a 2006 Acura TL. I'm doing the big 4 (grounding the alternator casing too) before the amp gets installed. Also I have a high output alternator that puts out 155A at idle.

The 4-channel isn't installed currently. Right now I just have a 2 channel amp powering two Alpine Type R's at 75W a piece. Everything is fine with it, but this new amp will be twice the power per channel and two more channels used.

Hi. I have an XStatic Model 400 Batcap that I use for my sub woofer amp. I'm about to get a higher power 4-channel speaker amp (150W per channel x 4). Would this amp now need to run through a cap?

Thank you for your responses. But mainly just do they sound THAT much better than the R's? And yes I understand the choice is still opinionated.

Hi. I'm trying to decide between the Alpine Type X or Type R 6.5" component system for my car. I will also be getting the same model (whatever I choose) for just 6.5" co-axials for my rear deck as well. All 4 of the speakers will be powered off Alpine's new Type X 4 channel amp (the X-A70F). Do...

I have not done the big 3, and no my front battery isn't old. It's a Diehard Gold Deep Cycle with 600CCA and a RC of 100 (those are the only specs I can find). I'm at the point now where I think I may have to upgrade my alternator because my system will be at 1900W (accounting for amp...

That's what I'm trying to determine. Would a half batcap/half battery like the Xstatic products (model 800, 2000, 3000, etc.) be better, or should I just get a large deep cycle battery (OPTIMA yellow top, XS D3400, XS D6500, etc.) to power my system? Also, would deep cycle batteries discharge...

Hi. My sound system is currently a little above 1200W with one sub amp (this is accounting for amp inefficiency) and will eventually be about 1900W (One sub amp and one speaker amp; again accounting for inefficiency). I have a XStatic Model 400 batcap (rated up to 1300W) on my system now...

Hi. I'm looking to find out some very detailed specs on the Alpine X-A70F amplifier. What I'm looking to find out is roughly what the true power output is per channel at 4 ohms (birth sheet gives highest power output at lowest ohms), what its true efficiency is, and its maximum current draw for...

Cool, thank you.

Hi. I have a XStatic Model 400 batcap for my sound system. When my system is all said and done it will be around 1,600W in total. On the company's website it says that for "maximum performance" this cap is rated between 1,000W-1,300W. I called a very reputable car audio store near me and they...

Ok cool. Thank you.

Thank you all for your suggestions. Another reason I asked about the two amp choices is because the batcap that I have says it’s rated for “maximum performance” between 1,000-1,300W and by putting in the amp that does 120Wx4 my system will be at 1,340W in total. I’m worried that will be too much...

Both of the amps are Alpine and both are 4 channel. Money is not a factor, I just want to know wattage wise will underpowering the speakers by 15W be ok, or should I get the amp that puts out 120W per channel? The amps I’m looking at are: Alpine PDR-F50 (4 channel 85W per channel at 4 ohms)...
