Wow you respond quick! I don't actully have speakers in it yet, I was going to do the same speakers I did in the bimmer. 4 5.25in nvx speakers (although Ill try to fit 6.5's) hooked to the same recoil amp (di800.4). I was so satisfied with those speakers that I would use them for this. The sub would probably over power them, but thats what im going for.IMHO, anything in the 1500 to 3000 watt range is going to get REALLY loud. there are diminishing returns after about 1000 watts, it takes exponential wattage to get there. 500 watts to a sub needs 1000 watts to get 3 db more output, 2000 watts to get another 3 db, 4000 watts to get a perceived 9 db boost or a doubling of the sound pressure level to the ear.
A system with lets say 3000 watts overall is most likely going to benefit from a helper battery in the rear next to the amplifier for sure. I think the alternator in that regal may be fine but benefit from a big three upgrade.
Keeping in mind balance, what is powering the other speakers and what speakers are you using?
1980 Buick regal 4 door.Guessing it is a 2000 regal? That old school?
Are they the exact same battery?I'm not running anything between my batteries...just the positive wire between the 2 batteries and the rear battery is grounded to the frame
But I'm also running agm on both...I don't know the mysteries of lithium yet
Nope different brands and sizes...just both agmAre they the exact same battery?
That Si is 9 db more efficient, thats double the volume at any given wattage. Unless my math is wonky, 2 of them will outperform that sundown 12 at the same wattage.That sundown has almost double the point to point travel over a sql-12...the sundown with move way more air...
That's only part of the equation cone area and movement play into it...I can get louder than sql on 1k with 500w given enough coneThat Si is 9 db more efficient, thats double the volume at any given wattage. Unless my math is wonky, 2 of them will outperform that sundown 12 at the same wattage.
And two 12s have twice the cone area. at max 1000 watts ea. - versus twice the wattage to push to get there on the single sundown. Take your pick but I'm giving the edge to the dual Si setup.That's only part of the equation cone area and movement play into it...I can get louder than sql on 1k with 500w given enough cone
The op stated a single sub...why bring 2 into itAnd two 12s have twice the cone area. at max 1000 watts ea. - versus twice the push to get there on the single sundown. Take your pick but I'm giving the edge to the dual Si setup.
