Did they give me the right amp for my subs?

[steven01]

Hi, I just got the Kicker L7 12 inch subs from 901 sounds in memphis. My concern is the amp the installed with my setup. Its a JVC

Arsenal KS-AR7501D Amp here are the specs:

* Arsenal Series 1-Channel Class D Car Amplifier

* RMS Power Rating:

o 4 ohms: 400 watts x 1 chan.

o 2 ohms: 700 watts x 1 chan.

o 1 ohm: 1000 watts x 1 chan.

* Max power output: 1200 watts x 1 chan.

* Pulse Width Modulated MOSFET Power Supply

* Remote bass level input (remote level control sold separately)

* Tuned Bass EQ (0-18 dB bass boost at 45 Hz)

* Single channel operation)

* Variable Speaker Level Input

* Stackable 4-Way Installation

* Anti-pop and protection circuit

* Phase Control (0/180°)

* 1 ohm Stable

* Large Top Mounted Rotary Controls

* Gold Plated RCA Input & Output(Pass Through)

* Angle Mount Gold-Plated Power & Speaker Terminals

* Variable low-pass filter (50-300 Hz, 18 dB/octave)

* Subsonic filter: 20-50 Hz

* CEA-2006 compliant amplifier

* Frequency response: 20-300 Hz

* Authorized Internet Dealer

* 2-year Manufacturer's warranty

Kicker l7 12s

Size (IN.,CM) 12, 30.5

Impedance (OHMS) 2 or 4 DVC

Max Rec Amplifier Power (WATTS PEAK/RMS)* 1500/750

Sensitivity (dB 1w/1m) 88.6

Frequency Response (Hz) 20-100

Mounting Depth (IN.,CM) 6-11/16, 16.9

Mounting Cutout, Square (IN.,CM) 11-1/16, 28.1

Min Rec Sealed Box Volume (CU. FT., Liters) .88, 24.9

Max Rec Sealed Box Volume (CU. FT., Liters) 2.0, 56.6

Min Rec Vented Box Volume (CU. Ft., Liters)** 1.75, 49.6

Max Rec Vented Box Volume (CU. Ft., Liters)** 3.25, 92.1

The max output power of the is amp is 1200 watts but the kicker l7s I have got a 1500 watt peak rating. So is this amp a little underpowered? I want my subs to sound the loudest possible. Thank you.

Also, how do I get my car door speakers to play louder. I'm hearing a lot of bass from my subs but not much music. Thanks.

This could get ugly. On the subs, you should be fine in my opinion. You never look at peak only at the rms watts of the sub. As far as the door speakers, you may just want to have them tune it for you or you can try tuning it yourslef, I'll wait for someone else to chime in on those.

if you want to give your subs there full RMS get a bigger amp. If its dual 2ohm get an amp that does 1500 at 1 ohm, If its dual 4 ohm get an amp that does 1500 at 2ohm. Upgrade to a set of components upfront powered by another amp to make them equal the output of your sub.

id definitely get a new amp, how much did they charge you for it?

Yeah dont look at max watts only pay attention to rms

Jvc makes amp ha, pry doesn't do rated power.

they prolly gave you 2 D4 subs to wire it to 1 ohm for the "1000" watts. what youll need to do is get an amp that does 1500 watts at 1ohm at least. you might have to upgrade the electrical a little bit depending on your car as well.

Did you get 2 subs? and what is the impedance of the subs you got? As far as the amp, it will run 1 L7 just fine. The amp is CEA compliant so it probably puts out the power it say's it does.
