corey0928 Posted June 25, 2010 Report Posted June 25, 2010 This may sound stupid but... I need to run an amp at 4 ohms (1500 rms @ 4) so say I buy an amp that is 3k @ 2 and 1500 @ 4, do I need to upgrade my electrical for the 3k or just the 1500?
kl0wn Posted June 25, 2010 Report Posted June 25, 2010 You need to upgrade your electrical according to how many amps the amplifier will be pulling. And running it at 4 ohms will be pulling less amperage than running it at 2 ohms. 06 Mini Cooper S Sundown, SoundQubed Cadence, XS Power 151s Sealed 155s Outlaw Windshield @ 37hz
Jared420 Posted June 25, 2010 Report Posted June 25, 2010 You will only need enough to support what you will be running, but to be smart, if you have a little extra cash its always a good idea to leave room or set yourself up for upgrades and going bigger. in the future. if your like most of us on here you will be constantly upgrading and changing, adding more power and its not worth the money to buy a nice beast amp without electrical because you will kill it will voltage drop, That being said it should be relatively inexpensive and easy to support your 1500 watts depending on the vehicle some could support that with stock electrical. 2012 silverado ext cab ltz 24" kmc rims AudioQue 2200 Pioneer AppRadio Alpine mrx f35 4 channel Bose mids and highs Iraggi Alt + stock alt in a DC power dual alternator kit Yellowtop+stock under hood 0 gauge Knu wire Big 3 4 gauge stinger (4 chan wiring) 3 DC 10'' LVL3 with LVL4 parts
corey0928 Posted June 25, 2010 Author Report Posted June 25, 2010 I already know I can support 2k with no real problem, I just know I will have a hard time finding an amp that is 1500@4 unless it's a 3k@2. And I am going to be getting a bigger alt after I get back from vacation and after I get the amp,

And I am going to be getting a bigger alt after I get back from vacation and after I get the amp, I believe the Rockford T2500-1bd is rated for 1500@4 and 2k@2.
