Ok I need some help. Can a 1800 Watt Amp power two 12" rockford He subs and four Alpine 5x7" interior speakers?

All speakers are brand new, as are the subs, and the amp and the Head Unit (Alpine).

I currently have the amp JUST powering the Subs and nothing else, and when I turn the volume up so you can hear the subs, the speakers get all distorted and it sounds terrible. I was thinking of hooking the speakers up to the amp also but im not sure if theres enough power or if its the right thing to do. Anyone know?

Specs:

Head Unit: 50Wx4 Amplifier, 4v preout

Interior Speakers(four): 200 Watts Peak, 40 Watts RMS

Subs(two): 400 Watts Peak, 200 Watts RMS

Amplifier: Maximum Power 1800 Watts,

4 0hm load- 150 Watts x2,

2 0hm load- 300 Watts x2,

4 0hm load- 600 Watts x1

I really dont know much about this stuff so I really need some help. I bought everything at best buy and it sounded amazing there, but terrible in my car. But i dont know how they wired everything

Any help is much appreciated.

(P.S.- I put alot of money into this, anyone know of ways to prevent theft of this stuff? Already have an alarm, but if im not around its not going to stop anyone)

Thanks again

ok first off, when u get into the true audio world.....MAX power ratings mean absolutely nothing. we go on the RMS of the amps.

And since ur amp is a 2 channel amp, unfortunately you can't run ur 4 speakers off of it as well. I'm assuming u bought aftermarket speakers upgrading from the factory speakers correct? well they are probably only getting around 15-20w(at the most) from the HU.

So what your gonna wanna do is buy a 4 channel amp that is 40-50 watts per channel so you can power the 4 speakers.

Ok, so do I need any extra things to have both amps running at once? Seems like its a lot of power getting sucked from the battery. Also I'm kind of worried about getting this stuff stolen, any security ideas?

The speakers are brand new Alpine SPS-570A. I need a way to just increase the bass without having the speaker volume go up. Not sure how to do that though I played around with bass and subwoofer settings on the HU. Any ideas?

shrinkydinx -- "your HU is putting too much bass into them, when the bass should only be going to the subs..."

I agree with shrink here sounds like you are putting to much bass into your speakers. you could see if you can buy some bass reducers from your stereo store they clean up the speakers some cost a bit less than buying a whole amp and wiring kit, and its less to be advertised to be stolen

Yuppers, i agree with whoever suggested getting another 4 channel, amping speakers is the way to go if you want good sound, and it to get hella loud...

Why not just run a second amp for your speakers and not worry about running them all off of the same one? And BTW why did you have Best Buy wire everything for you, they dont know what they are doing.

No I had a car audio store wire everything, and I have the bass for the speakers turned all the way down, and subwoofer output volume all the way up. Even with the bass control for speakers all the way down, there is still bass from them at higher volume. There's no way to get absolutely no base to go to the speakers.

yes there is. Tell us what Head Unit u have and maybe we can help you out. Some head units have High Pass Filters on them for the front and rear speakers. HPF will cut out the bass frequencies.

The HU is an Alpine CDA-9811
