m720bos Posted March 18, 2014 Report Posted March 18, 2014 If i have two of the same subs, but one is dual 4 and the other is dual 2, if wire one at 2 ohms on one amp and the other at 2 ohms on the other amp will that essentially be the same? will they perform the same? or is that just stupid?
audiofanaticz Posted March 18, 2014 Report Posted March 18, 2014 No, because the dual 4 can only be wired at 2 or 8 ohms, and the dual 2 can only be wired at 1 or 4 ohms. So chances of you finding an amp to do the same wattage at 2 ohms as the other can do at 1 ohm will be slim to none, and even then the amps will react completley different to things such as voltage drop, impedance rise, etc. Unless you only wire up one coil and than the woofer wont work to its full performance since the BL would be cut in half, the subwoofers power handling would be less, and overall a bad idea.

m720bos Posted March 18, 2014 Author Report Posted March 18, 2014 yea i realized that i couldnt wire the d2 to 2 ohm right after i posted that......... brain fart...... i have 2 of the same amp and i was about to buy a second sub from this guy but guess its a bad idea cuz of the ohm difference. having one at 2 ohm and one at 1 ohm would def have them sounding different
dubtuner98284 Posted March 18, 2014 Report Posted March 18, 2014 wouldn't wiring one at 2 ohm and one at 1 ohm then bridging them produce a 1.5 ohm load giving you something you can run of a single amp? Just a question.
truthsayer Posted March 18, 2014 Report Posted March 18, 2014 If you wired both to one amp, you would either have a final load of .66 or 3. Depending on parallel or series wiring. And with two different impediances of the subs, i don't think they would respond the same. truthsayer
dubtuner98284 Posted March 18, 2014 Report Posted March 18, 2014 I guess I went the wrong way on ohm load. Sorry for the brain fart. I remember wiring two 4 ohm and two 8 ohm Cerwin Vega speakers to my home stereo once before. I ended up using one 4 ohm and one 8 ohm per channel. It was a non bridgeable amp. I seem to remember similar output from each woofer. Rms requirements were similar for each woofer. I don't know if it makes a huge difference in car audio though.
bassman619 Posted March 18, 2014 Report Posted March 18, 2014 I think its a bad idea..if you have the 4 ohm dvc then get another 4 ohm and wire to 1 ohm..if you have a 2 ohm..get another 2 ohm n wire to 2 ohm or .5 ohms.be careful with .5 ohms..if you dont have a amp stable for it and/ or sufficient electrical you will fry some shit... You need trunk space to get groceries and shit...bitches love groceries
Aj11 Posted March 18, 2014 Report Posted March 18, 2014 yea they will move differently. we tried this. i have 2 dual 4ohm 12s i wired one to 2ohm the other to 8ohm on the same amp. the 8ohm sub moved much less then the 2 ohm sub jvc deck stinger 1800 front hc 2000 kinetic rear 2 runs of 1/0g big 3/4 ct 60.4 2 ct 1400.1 ct EXO 15 d1 lots of deadner type r comps front stage 6 kicker tweets rear stage lots of great stuff coming soon ho alt more bats ct comps for front stage more deadner sweet amp rack lots of L.E.D lights new deck (thinking 80 prs, or flip out)
