No pix yet, the system is in, but the car isnt totally reassembled. And its in shambles. lol But Ive been testing it out and it sounds great, however, theres not enough midrange in the sound. I've messed with the HU EQ and still not getting what I want.

Heres my setup:
- Diamond Audio D661a Component Speakers up front
Specs: 6 1/2 In., 100/200 Watts

-Alpine MRV-F345 Multi Channel Amp
Specs: 4/3/2, 75 RMS x4,
*** Actually I have a temp amp, a newer smaller Alpine, the MRP-F250 powering the front speakers while my other amp gets repaired. **

- 2 Alpine SWR-1022D (10") Subs

- Alpine MRD-M1005 Mono Amp

- Subthump Dual 10" T-Top Box

Now, my questions are... is it possible the amp isnt providing enough power to the speakers? (We didnt bridge it.) Or that the amp itself could be adjusted to correct this? (I'm really thinking its amp related) Could some lower frequency sail panel speakers fix my problem if its not the amp? Could it be a power issue? (Yellow top going in, alternator more than likely in the future.)

Any help would be nice. The components are naturally brighter sounding, but I've heard them before and I dont remember them lacking this much in the mid range. So I'm at a loss.

Thanks.

Whats the crossover freq. set at on the amp?

I'm not sure, my friend is the one who took care of that. I just ran most of the wires. lol I didnt even know that there was an option for that, I'll take a look.

woswill

the freq on my amp was like 100 or so, i put it around 180 and it sounds fine now

It's set at 75, which by comparison seems very low. I'll mess with it a bit.

75 hz is a pretty good place for it.

Most people have their crossovers set between 40 and 100 hz. Mine are set at 80 hz and the subs pick up everything else below 80 hz.

What is the lowpass set at for the subs?

My question is but how do you like thoes subs?

Stop giving horrible advice. It's nice that you seem willing to offer suggestions and all, but please learn what you're talking about first. 100Hz is the absolute max subwoofer crossover frequency, and closer to 80Hz is usually better.

I love the subs, they hit hard and clean. Great bang for the buck for sure.

Dragon, he was talking about an amp powering components, not subs.

I think my problem lies in this temp amp underpowering the speakers. We didnt even bridge it, so theyre only seeing 50w. Which more than likely just isnt enough. So I need to figure out how to bridge this amp, I dont need the bridge the RCA's as well do I? It shows something about a y connector in the manual, but I dont see why thats needed?

dragonrage

Yes, that goes for the low end on speakers as well. Your highpass on the woofers is the same as a sub crossover, even if you don't have a sub.

I see. My mistake then.

Edit: Whoops, I don't understand. What are you talking about with Y cables? If it's taking 2 RCAs and putting them in through a Y cable to go into a mono amp, then you don't need it.

Its a multi channel amp with the RCA's just regularly plugged in to it from the HU. But the diagram shows something about bridging the RCA's as well. Which I dont follow... why would you do that?

dragonrage

To get more power if you don't need the extra channels...

Through the RCA's? I didnt think that would affect the amount of power going to the speakers.
