Jextel Posted August 4, 2009 Report Share Posted August 4, 2009 alot ppl around here does/want stuff like this..IMO i really dont care..but when i had my hdc3s in my trunk i was louder than this guy with 3 10s and 2 15s in his expo...lol Quote http://www.cardomain.com/ride/3042878TEAM DEADLY HERTZ "GET LOUD OR DIE TRYIN"only the loudest will survive.

siucsaluki11 Posted August 4, 2009 Report Share Posted August 4, 2009 im confused, why would u do thatmix different sizes and different subs on the same amp too... i could see it on 2 amps, maybe. But on the same amp just sounds like a bad idea. Personally, id never mix and match unless it was a passive radiator setup. But to each their own.

Blazer=========================Last setup was in the 141s on music (37hz) with 2 12s and 1kw in a 4dr blazer.2010 Mitsubishi Lancer DE2 12in Clarions (kept from blazer)HiFonics BRZ1700.1d (at 2 ohms BLOWN) [JBL GTS180X for subs currently 60wRMS x2ch!!!!!! This works for till i get the blown amp fixed] Alpine 4ch salvaged from blazer (currently near death)9887 peerless 7s in the doors and CDT tweeters ran active no speakers in the rearKintik HC1400 under the hood.metered once a while ago, dont remember it...was piss poor compared to the blazer, mid 130s i think....looking to replace subs and amp when i have money.

Hotdog Posted August 4, 2009 Author Report Share Posted August 4, 2009 (edited) i could see it on 2 amps, maybe. But on the same amp just sounds like a bad idea. Personally, id never mix and match unless it was a passive radiator setup. But to each their own. I actually have another amp but I am not going to hook it up until I get my new Alternator I would lover to hook it up but then I would be pushing like 2000 RMS out of a stock 135amp Alt.. do have a Kinetic HC600 but that still would not be enough I dont think. I am able to hold above 13v at full tilt now Edited August 4, 2009 by Hotdog Quote (NEW) 2004 F-150 Build Log -->http://www.stevemeadedesigns.com/board/topic/192208-hotdogs-f-150-build-log/ 2003 Mercury Mountaineer Build Log --> http://www.stevemeadedesigns.com/board/topic/114380-hotdogs-2003-mountaineer-build-log-20-removed/page__gopid__1602379#entry1602379 2008 Equinox Build Log --> http://www.stevemead...g/#entry1475764 Link to comment Share on other sites More sharing options...

Decaf Posted August 4, 2009 Report Share Posted August 4, 2009 (edited) ok well ill be nice, but... thats a no go in my book and many others different subs have different specs, so it doesnt matter what volume the boxes are vs manufactuers specs because the subs dont match, so they wont react the same to the power or notes played you also used the same port surface area for the 12s and 15s... to make any of this logically work u would have needed to keep the same port surface area ratio vs box volume the same... along with using the same subs... and even then there will be cancellation and phasing issues with different sizes as the specs from 12s to 15s of the same sub are different if at any point in time u see the 12s or 15s not moving the same amount or at the same time... ur not in phase and will cause cancelation which will bring down ur score and just make all bass sound muddy and boomy since notes wont be clearly defined a video of the subs moving would show the subs not moving identically especially with a slower frame rate than the naked eye im not completely sure u know that so im not trying to be rude, just saying its not ideal at all to do it in this fashion for daily or competing... adding another amp would make it even more of a problem because then ud have two different amounts of power being delivered to two different sized subs that are different models... lots of places for issues how are the 4 subs wired... what ohm subs are they?

I yea I gotta say Im with Decaf on this one bro, I usually dont comment much on other people posts b/c there are many knowledgable people on this forum who can offer much better advice than I. However, I saw this and was like what the... Dont get me wrong nice box and build for sure bro kudos on that, but on the same mono block amp, with what is essentially two dif boxes and two dif sets of subs sounds iffy at best. Youre talking dif impeadences, dif reactives, really just dif everything. Wait to put your second amp on the second set of subs, but untill then id stick with the 15's. As always I could be wrong, and you could be ok running it like that.

Hotdog Posted August 5, 2009 Author Report Share Posted August 5, 2009 (edited) how are the 4 subs wired... what ohm subs are they? oh I will tell you but you are really going to think (WTF) .. All four subs are dual 4 ohm... the P2's are rated at 250 rms / 500 peak and the Punch Power 15's are rated at 1000 RMS / 2000 peak so I wired the 15's to one ohm and the 12's to 4 ohm then wired the 4 ohm subs to the 1 ohm subs with technically should give me a .8 ohm load but when tested with the Multimeter it came out to 1.1ohm. I have not tested the actual power to each sub but I was thinking in theory ( I could be wrong though ) that the 15's will be getting a lot more power then the 12's since they are wired at 1ohm and the 12's are wired at 4 ohm. on the 15's each sub is wired to 2 ohm then wired to each other to 1 ohm. The 12's each sub is wired to 8 ohm then wired together down to 4ohm. Then the 4 ohm and 1 ohm are wired together to get a hypothetical .8 ohm but it is actually seeing 1.1 ohm. how would one figure out how much wattage each sub is getting in theory with this wire configuration Edited August 5, 2009 by Hotdog Quote (NEW) 2004 F-150 Build Log -->http://www.stevemeadedesigns.com/board/topic/192208-hotdogs-f-150-build-log/ 2003 Mercury Mountaineer Build Log --> http://www.stevemeadedesigns.com/board/topic/114380-hotdogs-2003-mountaineer-build-log-20-removed/page__gopid__1602379#entry1602379 2008 Equinox Build Log --> http://www.stevemead...g/#entry1475764 Link to comment Share on other sites More sharing options...
Basshead08 Posted August 5, 2009 Report Share Posted August 5, 2009 This is just an all around bad idea bro. Never mix all the different aspects you have mixed.

Hotdog Posted August 5, 2009 Author Report Share Posted August 5, 2009 This is just an all around bad idea bro. Never mix all the different aspects you have mixed. but it all some how works great together... the nice tight bass tracks Rock are crisp and punchy and the heavy bass tracks will lay a beating on you. I have had a couple people that could not take the bass because it was hitting them to hard. I guess I am just use to it. and just to think I am a small fish in this forum a lot of people here would probably make me want to jump out.
