Before anyone goes bat-$#*! crazy on me, I've used Google and searched the forum, here and several others as well... But I'm looking for some final words of wisdom on this particular set-up, because I haven't found the answer to this particular question.
Backstory: I've been improving the sound system in my ol' car gradually. I have little to no budget (as we've heard a thousand times). I used to be a fairly decently paid art director in an advertising agency, and then a freelance illustrator... Then one day in my old age, I decided to join the Army. I have a wife and multiple dependents, so cash doesn't come easy, freely or in abundance. :)
I purchased some polk component speakers for my fronts and some polk coaxials for the rears (though I'm wondering if that was economical or just my need for symmetry. All of these are running off the head unit (which is cheap, but sounds clean even at moderately high levels).
But the Army moves people around like mad. My neighbor came over with a box of car audio stuff that wouldn't fit into his u-haul. New, it was about $500 in stuff, and he just gave it to me. I would never have purchased the items in that box, as saving up my money for some more worthwhile pieces would have been a priority in sound... But I peeked in, saw almost everything in its original packaging and took the box off his hands for the cash in my wallet (which was very little).
Don't judge me for using these things; I'm still saving up for improvements, but since I'm out very little money while I'm saving, I figure I'll make the most out of what I got. In the box i have:
One 1000w Sony 2 Channel Amp (really only 1000w max at 1 channel and 185w rated at 2 channels)
One 12" Sony Sub
Two Alpine Bass Engines (Butt-kickers or Tactile Transducers or whatever you want to call them; hence the parenthetical "subs" in the title of the post)
The 'speakers' are all 4ohm and the amp is 4ohm at 2 channels/2ohm at 1 channel.
I was hoping to get some safe options. I want to try these little shakers and the sub (the speakers I have are great at producing ear-bleeding highs and crisp, punchy mid-bass, but the lows are heavily missing) together, but spending more dough on another amp for this rather than a new headunit OR an amp to sufficiently power my speakers is not an option.
BUT everything I've read covers only power hungry subs (I'm powering one sub and 2 low, low power 'shakers) and wires everything bridged, which at 4ohms per sub always ends up being a 1.3333ohm or a 12ohm load is wired in a different way (but still bridged) and not in safe tolerance with the amplifier I have. But if I run the sub off one channel and run the alpines in series off the other channel, will this still read as a 1.3333ohm load or a 12ohm load?
I'm not in this "hobby" to spend money; I have an audiophile's ear, but I'm lacking the audiophile wallet. I just want some lows to balance out my music (sub) and maybe a bit of fun (alpine bass engines).
