Amplifier Wiring Questions

[MXmike800]

I have 3 type r 12 (4) ohm dvc. Below is RF wiring wizard and how i have them wired up to my amplifier.

these are the specs on my jbl 1201.1 amp

GTO1201.1

• 787W RMS x 1 channel at 4 ohms and ≤1% THD + N

• Signal-to-noise ratio: 70dBA (reference 1W into 4 ohms)

• 1114W RMS x 1 channel at 2 ohms, 14.4V supply and

≤1% THD + N

• Dynamic power: 1339W at 2 ohms

• Effective damping factor: 6.348 at 4 ohms

• Frequency response: 10Hz – 302Hz (–3dB)

• Maximum input signal: 6.1V

• Maximum sensitivity: 140mV

• Output regulation: .14dB at 4 ohms

• Dimensions (L x W x H): 18-11/16" x 12-5/16" x 2-3/8"

so i have my type r wired to a 2 ohm load. what im trying to understand is am i underpowering them? Alpine rates them at 500 rms 1500 max. im planning on buying another type r 12 should i buy another jbl amp and run 2 per amp or will this amp push all 4.

you currently feeding each 12 278.5watts, so YES, you are under powering them by 50% almost. I would of course buy another JBL amp and power 2 12"s per amp. However, you said your suns are D4's, if you wire 2 12 D4's you can only get a 1OHM, or 4OHM load, and you need to be @ 2ohm to get max RMS power. Personally I would ditch the JBL amp, and go for 1 monster amp that will give you 2000+RMS power @ 2OHM's (As this is the ohm load you will be at with 4 D4's subs wired correctly.)

Sell the JBL and get a Stetsom or a Kicker 2500
