Sorry in advance for what sounds like a book but i am not happy in the progress of the install....Here it is old school Eclipse competition cd player 3 sets of RE audio 6 1/2 components pushed by a US AMP md-43 4 channel....2 18in FI BTLS in a 6cuft box (ea) after displacement being pushed by 2 US AMPS md-3d rated at 2000rms @ 1ohm @14.4volts....I also have a 300amp alt big 3 done 5 optima batteries (looking to get XS POWER) and all 0 gauge wire.....Stinger volt meter that is ran to the sub at is ranging 14.7 to 14.0 (i know voltage drop isnt good im getting another 300 amp alt soon) It is loud and hits pretty hard (broke weld in tailgate that holds the handle so know it sounds like SHIT) and the cd player skips real bad on most songs (soon to go the VMOD on board carputer) but from what i have heard and seen about these subs mine are not there.....i am BARELY moving them...So i guess my question is do i just need more power (getting 2nd alt soon) and or do my sub amps just NOT have the power these power hungry subs want or need.......Please any insight would help out alot...I know i probably forgot some details you might need but just ask thanks again

Need more power.

as far as amps i know i need second alt but what amps would do these subs good...my wallet doesnt go real deep either

Was you box designed for your truck? Sealed or ported? Is it a blow thru? Walk thru?

well its in my 99 tahoe and the box is 6cuft per side after displacement and the subs fire up and the ports fire back tuned to 32hrtz

it was custom built

Do they have the Hixm coil?

they are dual 2ohm fully loaded so i can run them at 1ohm to ea amp

So how are the settings on these amps?

You enclosure is pretty small, they will be very strong mechanically with a small internal chamber.

I think you gotta fiddle with your levels on your amp... if you know your power is dirty don't get close to a clip but on sure you can get them subs moving with that power.

And what's your signal setup? Sound processor?

the amp settings are lil more then half on the gain subsonic is few below tune of box sublevel on deck is all the way up bass boost off........dont get me wrong its loud but not moving the sub very much cd player skips sooo bad its not funny....and the box is built by what FI stated..6cuft per sub after displacement should be good or am i wrong...tuned to 32hrtz

sounds like you got alot more in your ride than i do and i think my single BTL 18 does the damn thing. i only have a 220A alt and 2 kinetik battery's, and only running the sub with a sundown 1500 @ 1 ohm. I believe my box is alot closer to 8 cu ft though. Only complaint i have is not buying a 2nd one when the gen 2s were still for sale lol. just my .02 cents for ya. good luck
